Political science is the scientific study of politics. It is a social science dealing with systems of governance and power, and the analysis of political activities, political thought, political behavior, and associated constitutions and laws.
As a
social political science, contemporary political science started to take
shape in the latter half of the 19th century. At that time it began to
separate itself from political philosophy, which traces its roots back to the works of Aristotle and Plato,
which were written nearly 2,500 years ago. The term "political science"
was not always distinguished from political philosophy, and the modern
discipline has a clear set of antecedents including also moral
philosophy, political economy, political theology,
history, and other fields concerned with normative determinations of
what ought to be and with deducing the characteristics and functions of
the ideal state.
The advent of political science as a university discipline was
marked by the creation of university departments and chairs with the
title of political science arising in the late 19th century. In fact,
the designation "political scientist" is typically for those with a
doctorate in the field, but can also apply to those with a master's in
the subject.Integrating political studies of the past into a unified discipline is
ongoing, and the history of political science has provided a rich field
for the growth of both normative and positive political science, with each part of the discipline sharing some historical predecessors. The American Political Science Association and the American Political Science Review were founded in 1903 and 1906, respectively, in an effort to distinguish the study of politics from economics and other social phenomena.
In
the 1950s and the 1960s, a behavioural revolution stressing the
systematic and rigorously scientific study of individual and group
behaviour swept the discipline. A focus on studying political behaviour,
rather than institutions or interpretation of legal texts,
characterized early behavioural political science, including work by Robert Dahl, Philip Converse, and in the collaboration between sociologist Paul Lazarsfeld and public opinion scholar Bernard Berelson.
The late 1960s and early 1970s witnessed a takeoff in the use of deductive, game-theoretic
formal modelling techniques aimed at generating a more analytical
corpus of knowledge in the discipline. This period saw a surge of
research that borrowed theory and methods from economics to study
political institutions, such as the United States Congress, as well as
political behaviour, such as voting. William H. Riker and his colleagues and students at the University of Rochester were the main proponents of this shift.
Despite considerable research progress in the discipline based on
all the kinds of scholarship discussed above, it has been observed that
progress toward systematic theory has been modest and uneven.
Recent developments
In 2000, the Perestroika Movement
in political science was introduced as a reaction against what
supporters of the movement called the mathematicization of political
science. Those who identified with the movement argued for a plurality
of methodologies and approaches in political science and for more
relevance of the discipline to those outside of it.
Some evolutionary psychology
theories argue that humans have evolved a highly developed set of
psychological mechanisms for dealing with politics. However, these
mechanisms evolved for dealing with the small group politics that
characterized the ancestral environment and not the much larger
political structures in today's world. This is argued to explain many
important features and systematic cognitive biases of current politics.
Political science is a social study concerning the allocation and transfer of power in decision making, the roles and systems of governance including governments and international organizations, political behaviour, and public policies. It measures the success of governance and specific policies by examining many factors, including stability, justice, material wealth, peace, and public health. Some political scientists seek to advance positive theses (which attempt to describe how things are, as opposed to how they should be) by analysing politics; others advance normative
theses, such as by making specific policy recommendations. The study of
politics and policies can be closely connected—for example, in
comparative analyses of which types of political institutions tend to
produce certain types of policies.
Political scientists may provide the frameworks from which journalists, special interest groups, politicians, and the electorate analyse issues. According to Chaturvedy,
Political scientists may serve as
advisers to specific politicians, or even run for office as politicians
themselves. Political scientists can be found working in governments, in
political parties, or as civil servants. They may be involved with non-governmental organizations
(NGOs) or political movements. In a variety of capacities, people
educated and trained in political science can add value and expertise to
corporations. Private enterprises such as think tanks, research institutes, polling and public relations firms often employ political scientists.
Country-specific studies
Political
scientists may study political phenomena within one specific country;
for example, they may study just the politics of the United States or just the politics of China.
The theory of political transitions, and the methods of analyzing and anticipating crises,
form an important part of political science. Several general indicators
of crises and methods were proposed for anticipating critical
transitions. Among them, one statistical indicator of crisis, a simultaneous increase of variance and correlations in large groups, was proposed for crisis anticipation and may be successfully used in various areas.
Its applicability for early diagnosis of political crises was
demonstrated by the analysis of the prolonged stress period preceding
the 2014 Ukrainian economic and political crisis.
There was a simultaneous increase in the total correlation between the
19 major public fears in the Ukrainian society (by about 64%) and in
their statistical dispersion (by 29%) during the pre-crisis years.
A feature shared by certain major revolutions is that they were not
predicted. The theory of apparent inevitability of crises and
revolutions was also developed.
The study of major crises, both political crises and external
crises that can affect politics, is not limited to attempts to predict
regime transitions or major changes in political institutions. Political
scientists also study how governments handle unexpected disasters, and
how voters in democracies react to their governments' preparations for
and responses to crises.
Cognate fields
Most political scientists work broadly in one or more of the following five areas:
Program evaluation
is a systematic method for collecting, analyzing, and using information
to answer questions about projects, policies, and programs,
particularly about their effectiveness and efficiency. In both the
public and private sectors, stakeholders often want to know whether the
programs they are funding, implementing, voting for, receiving, or
objecting to are producing the intended effect. While program evaluation
first focuses on this definition, important considerations often
include how much the program costs per participant, how the program
could be improved, whether the program is worthwhile, whether there are
better alternatives, whether there are unintended outcomes, and whether
the program goals are appropriate and useful.
Policy analysis
is a technique used in public administration to enable civil servants,
activists, and others to examine and evaluate the available options to
implement the goals of laws and elected officials.
Some political science departments also classify methodology as well as scholarship on the domestic politics of a particular country as distinct fields. In the United States, American politics is often treated as a separate subfield.
In contrast to this traditional classification, some academic
departments organize scholarship into thematic categories, including
political philosophy, political behaviour (including public opinion, collective action, and identity), and political institutions (including legislatures and international organizations).
Political science conferences and journals often emphasize scholarship
in more specific categories. The American Political Science Association,
for example, has 42 organized sections that address various methods and
topics of political inquiry.
Political science is methodologically diverse; political scientists
approach the study of politics from a host of different ontological
orientations and with a variety of different tools. Because political
science is essentially a study of human behaviour, in all aspects of politics, observations in controlled environments are often challenging to reproduce or duplicate, though experimental methods are increasingly common (see experimental political science). Citing this difficulty, former American Political Science Association President Lawrence Lowell once said "We are limited by the impossibility of experiment. Politics is an observational, not an experimental science."
Because of this, political scientists have historically observed
political elites, institutions, and individual or group behaviour in
order to identify patterns, draw generalizations, and build theories of
politics.
Like all social sciences, political science faces the difficulty
of observing human actors that can only be partially observed and who
have the capacity for making conscious choices, unlike other subjects
such as non-human organisms in biology or inanimate objects as in physics.
Despite the complexities, contemporary political science has progressed
by adopting a variety of methods and theoretical approaches to
understanding politics, and methodological pluralism is a defining feature of contemporary political science.
Empirical political science methods include the use of field experiments, surveys and survey experiments, case studies, process tracing, historical and institutional analysis, ethnography, participant observation, and interview research.
Political scientists also use and develop theoretical tools like
game theory and agent-based models to study a host of political systems
and situations.
Political science may overlap with topics of study that are the
traditional focuses of other social sciences—for example, when
sociological norms or psychological biases
are connected to political phenomena. In these cases, political science
may either inherit their methods of study or develop a contrasting
approach. For example, Lisa Wedeen has argued that political science's approach to the idea of culture, originating with Gabriel Almond and Sidney Verba and exemplified by authors like Samuel P. Huntington, could benefit from aligning more closely with the study of culture in anthropology.
In turn, methodologies that are developed within political science may
influence how researchers in other fields, like public health, conceive
of and approach political processes and policies.
Education
Political
science, possibly like the social sciences as a whole, "as a discipline
lives on the fault line between the 'two cultures' in the academy, the sciences and the humanities." Thus, in some American colleges where there is no separate school or college of arts and sciences per se, political science may be a separate department housed as part of a division or school of humanities or liberal arts. Whereas classical political philosophy is primarily defined by a concern for Hellenic and Enlightenment thought, political scientists are also marked by a great concern for "modernity" and the contemporary nation state, along with the study of classical thought, and as such share more terminology with sociologists (e.g., structure and agency).
Most United Statescolleges and universities offer BA programs in political science. MA or MAT and PhD or EdD programs are common at larger universities. The term political science is more popular in North America
than elsewhere; other institutions, especially those outside the United
States, see political science as part of a broader discipline of political studies,politics, or government. While political science implies the use of the scientific method, political studies implies a broader approach, although the naming of degree courses does not necessarily reflect their content. Separate programs (often professional degrees) in international relations and public policy are not uncommon at both the undergraduate and postgraduate levels. Master's-level programs in public administration
are professional degrees covering public policy along with other
applied subjects; they are often seen as more linked to politics than
any other discipline, which may be reflected by being housed in that
department.
The national honour society for college and university students of government and politics in the United States is Pi Sigma Alpha.
Iustitia ("Lady Justice") is a symbolic personification of the coercive power of a tribunal: a sword representing state authority, scales representing an objective standard and a blindfold indicating that justice should be impartial.
The law is legislation created and enforced through social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions. Private individuals may create legally binding contracts,
including arbitration agreements that adopt alternative ways of
resolving disputes to standard court litigation. The creation of laws
themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people.
Legal systems vary between countries, with their differences analysed in comparative law. In civil lawjurisdictions, a legislature or other central body codifies and consolidates the law. In common law systems, judges make binding case law through precedent, although on occasion this may be overturned by a higher court or the legislature. Historically, religious law influenced secular matters, and is still used in some religious communities. Sharia law based on Islamic principles is used as the primary legal system in several countries, including Iran and Saudi Arabia.
But what, after all, is a law? [...] When I say that the object of
laws is always general, I mean that law considers subjects en masse and
actions in the abstract, and never a particular person or action. [...]
On this view, we at once see that it can no longer be asked whose
business it is to make laws, since they are acts of the general will;
nor whether the prince is above the law, since he is a member of the
State; nor whether the law can be unjust, since no one is unjust to
himself; nor how we can be both free and subject to the laws, since they
are but registers of our wills.
The philosophy of law is commonly known as jurisprudence. Normative
jurisprudence asks "what should law be?", while analytic jurisprudence
asks "what is law?"
There have been several attempts to produce "a universally acceptable definition of law". In 1972, Baron Hampstead suggested that no such definition could be produced. McCoubrey and White said that the question "what is law?" has no simple answer. Glanville Williams said that the meaning of the word "law" depends on the context in which that word is used. He said that, for example, "early customary law" and "municipal law" were contexts where the word "law" had two different and irreconcilable meanings. Thurman Arnold
said that it is obvious that it is impossible to define the word "law"
and that it is also equally obvious that the struggle to define that
word should not ever be abandoned.
It is possible to take the view that there is no need to define the
word "law" (e.g. "let's forget about generalities and get down to cases").
One definition is that law is a system of rules and guidelines
which are enforced through social institutions to govern behaviour. In The Concept of Law Hart argued law is a "system of rules"; Austin said law was "the command of a sovereign, backed by the threat of a sanction"; Dworkin describes law as an "interpretive concept" to achieve justice in his text titled Law's Empire; and Raz argues law is an "authority" to mediate people's interests. Holmes said, "The prophecies of what the courts will do in fact, and nothing more pretentious, are what I mean by the law." In his Treatise on Law
Aquinas argues that law is a rational ordering of things which concern
the common good that is promulgated by whoever is charged with the care
of the community. This definition has both positivist and naturalist elements.
Definitions of law often raise the question of the extent to which law incorporates morality. John Austin's utilitarian answer was that law is "commands, backed by threat of sanctions, from a sovereign, to whom people have a habit of obedience". Natural lawyers on the other side, such as Jean-Jacques Rousseau, argue that law reflects essentially moral and unchangeable laws of nature. The concept of "natural law" emerged in ancient Greek philosophy concurrently and in connection with the notion of justice, and re-entered the mainstream of Western culture through the writings of Thomas Aquinas, notably his Treatise on Law.
When having completed the first two parts of his book Splendeurs et misères des courtisanes, which he intended to be the end of the entire work, Honoré de Balzac visited the Conciergerie. Thereafter, he decided to add a third part, finally named Où mènent les mauvais chemins (The Ends of Evil Ways), entirely dedicated to describing the conditions in prison. In this third part, he states:
The law is good, it is necessary,
its execution is poor, and the manners judge the laws based on the
manner in which they are executed.
Hugo Grotius,
the founder of a purely rationalistic system of natural law, argued
that law arises from both a social impulse—as Aristotle had
indicated—and reason. Immanuel Kant believed a moral imperative requires laws "be chosen as though they should hold as universal laws of nature". Jeremy Bentham and his student Austin, following David Hume, believed that this conflated the "is" and what "ought to be" problem. Bentham and Austin argued for law's positivism; that real law is entirely separate from "morality". Kant was also criticised by Friedrich Nietzsche, who rejected the principle of equality, and believed that law emanates from the will to power, and cannot be labeled as "moral" or "immoral".
In 1934, the Austrian philosopher Hans Kelsen continued the positivist tradition in his book the Pure Theory of Law.
Kelsen believed that although law is separate from morality, it is
endowed with "normativity", meaning we ought to obey it. While laws are
positive "is" statements (e.g. the fine for reversing on a highway is €500); law tells us what we "should" do. Thus, each legal system can be hypothesised to have a basic norm (Grundnorm) instructing us to obey. Kelsen's major opponent, Carl Schmitt, rejected both positivism and the idea of the rule of law because he did not accept the primacy of abstract normative principles over concrete political positions and decisions. Therefore, Schmitt advocated a jurisprudence of the exception (state of emergency), which denied that legal norms could encompass all of the political experience.
Bentham's utilitarian theories remained dominant in law until the 20th century.
Later in the 20th century, H. L. A. Hart attacked Austin for his simplifications and Kelsen for his fictions in The Concept of Law.
Hart argued law is a system of rules, divided into primary (rules of
conduct) and secondary ones (rules addressed to officials to administer
primary rules). Secondary rules are further divided into rules of
adjudication (to resolve legal disputes), rules of change (allowing laws
to be varied) and the rule of recognition (allowing laws to be
identified as valid). Two of Hart's students continued the debate: In
his book Law's Empire, Ronald Dworkin attacked Hart and the positivists for their refusal to treat law as a moral issue. Dworkin argues that law is an "interpretive concept",
that requires judges to find the best fitting and most just solution to
a legal dispute, given their constitutional traditions. Joseph Raz, on the other hand, defended the positivist outlook and criticised Hart's "soft social thesis" approach in The Authority of Law.
Raz argues that law is authority, identifiable purely through social
sources and without reference to moral reasoning. In his view, any
categorisation of rules beyond their role as authoritative instruments
in mediation are best left to sociology, rather than jurisprudence.
King Hammurabi is revealed the code of laws by the Mesopotamian sun god Shamash, also revered as the god of justice.
The history of law links closely to the development of civilization. Ancient Egyptian law, dating as far back as 3000 BC, was based on the concept of Ma'at and characterised by tradition, rhetorical speech, social equality and impartiality. By the 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code, which consisted of casuistic statements ("if … then ..."). Around 1760 BC, King Hammurabi further developed Babylonian law, by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae, for the entire public to see; this became known as the Codex Hammurabi. The most intact copy of these stelae was discovered in the 19th century by British Assyriologists, and has since been fully transliterated and translated into various languages, including English, Italian, German, and French.
The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society. The small Greek city-state, ancient Athens, from about the 8th century BC was the first society to be based on broad inclusion of its citizenry, excluding women and the slave class. However, Athens had no legal science or single word for "law", relying instead on the three-way distinction between divine law (thémis), human decree (nomos) and custom (díkē). Yet Ancient Greek law contained major constitutional innovations in the development of democracy.
Roman law
was heavily influenced by Greek philosophy, but its detailed rules were
developed by professional jurists and were highly sophisticated. Over the centuries between the rise and decline of the Roman Empire, law was adapted to cope with the changing social situations and underwent major codification under Theodosius II and Justinian I. Although codes were replaced by custom and case law during the Early Middle Ages,
Roman law was rediscovered around the 11th century when medieval legal
scholars began to research Roman codes and adapt their concepts to the canon law, giving birth to the jus commune. Latin legal maxims (called brocards) were compiled for guidance. In medieval England, royal courts developed a body of precedent which later became the common law. A Europe-wide Law Merchant
was formed so that merchants could trade with common standards of
practice rather than with the many splintered facets of local laws. The
Law Merchant, a precursor to modern commercial law, emphasised the
freedom to contract and alienability of property. As nationalism grew in the 18th and 19th centuries, the Law Merchant was incorporated into countries' local law under new civil codes. The Napoleonic and German
Codes became the most influential. In contrast to English common law,
which consists of enormous tomes of case law, codes in small books are
easy to export and easy for judges to apply. However, today there are
signs that civil and common law are converging. EU law is codified in treaties, but develops through de facto precedent laid down by the European Court of Justice.
The Constitution of India
is the longest written constitution for a country, containing 444
articles, 12 schedules, numerous amendments and 117,369 words.
Ancient India and China represent distinct traditions of law, and have historically had independent schools of legal theory and practice. The Arthashastra, probably compiled around 100 AD (although it contains older material), and the Manusmriti (c. 100–300 AD) were foundational treatises in India, and comprise texts considered authoritative legal guidance. Manu's central philosophy was tolerance and pluralism, and was cited across Southeast Asia. During the Muslim conquests in the Indian subcontinent, sharia was established by the Muslim sultanates and empires, most notably Mughal Empire's Fatawa-e-Alamgiri, compiled by emperor Aurangzeb and various scholars of Islam. In India, the Hindu legal tradition, along with Islamic law, were both supplanted by common law when India became part of the British Empire. Malaysia, Brunei, Singapore and Hong Kong
also adopted the common law system. The eastern Asia legal tradition
reflects a unique blend of secular and religious influences. Japan was the first country to begin modernising its legal system along western lines, by importing parts of the French, but mostly the German Civil Code. This partly reflected Germany's status as a rising power in the late 19th century. Similarly, traditional Chinese law gave way to westernisation towards the final years of the Qing Dynasty in the form of six private law codes based mainly on the Japanese model of German law. Today Taiwanese law retains the closest affinity to the codifications from that period, because of the split between Chiang Kai-shek's nationalists, who fled there, and Mao Zedong's
communists who won control of the mainland in 1949. The current legal
infrastructure in the People's Republic of China was heavily influenced
by SovietSocialist law, which essentially inflates administrative law at the expense of private law rights.
Due to rapid industrialisation, today China is undergoing a process of
reform, at least in terms of economic, if not social and political,
rights. A new contract code in 1999 represented a move away from
administrative domination. Furthermore, after negotiations lasting fifteen years, in 2001 China joined the World Trade Organization.

In general, legal systems can be split between civil law and common law systems. Modern scholars argue that the significance of this distinction has progressively declined; the numerous legal transplants,
typical of modern law, result in the sharing by modern legal systems of
many features traditionally considered typical of either common law or
civil law. The term "civil law", referring to the civilian legal system originating in continental Europe, should not be confused with "civil law" in the sense of the common law topics distinct from criminal law and public law.
The third type of legal system—accepted by some countries without separation of church and state—is religious law, based on scriptures.
The specific system that a country is ruled by is often determined by
its history, connections with other countries, or its adherence to
international standards. The sources
that jurisdictions adopt as authoritatively binding are the defining
features of any legal system. Yet classification is a matter of form
rather than substance since similar rules often prevail.
Civil law is the legal system used in most countries around the world
today. In civil law the sources recognised as authoritative are,
primarily, legislation—especially codifications in constitutions or statutes passed by government—and custom. Codifications date back millennia, with one early example being the BabylonianCodex Hammurabi. Modern civil law systems essentially derive from legal codes issued by Byzantine Emperor Justinian I in the 6th century, which were rediscovered by 11th century Italy. Roman law in the days of the Roman Republic and Empire was heavily procedural, and lacked a professional legal class. Instead a lay magistrate, iudex,
was chosen to adjudicate. Decisions were not published in any
systematic way, so any case law that developed was disguised and almost
unrecognised.
Each case was to be decided afresh from the laws of the State, which
mirrors the (theoretical) unimportance of judges' decisions for future
cases in civil law systems today. From 529 to 534 AD the Byzantine Emperor Justinian I
codified and consolidated Roman law up until that point, so that what
remained was one-twentieth of the mass of legal texts from before. This became known as the Corpus Juris Civilis.
As one legal historian wrote, "Justinian consciously looked back to the
golden age of Roman law and aimed to restore it to the peak it had
reached three centuries before." The Justinian Code remained in force in the East until the fall of the Byzantine Empire. Western Europe, meanwhile, relied on a mix of the Theodosian Code and Germanic customary law until the Justinian Code was rediscovered in the 11th century, and scholars at the University of Bologna used it to interpret their own laws. Civil law codifications based closely on Roman law, alongside some influences from religious laws such as canon law, continued to spread throughout Europe until the Enlightenment; then, in the 19th century, both France, with the Code Civil, and Germany, with the Bürgerliches Gesetzbuch,
modernised their legal codes. Both these codes influenced heavily not
only the law systems of the countries in continental Europe (e.g.
Greece), but also the Japanese and Korean legal traditions. Today, countries that have civil law systems range from Russia] and Turkey to most of Central and Latin America.
Anarchism has been practiced in society in much of the world. Mass anarchist communities, ranging from Syria to the United States, exist and vary from hundreds to millions. Anarchism encompasses a broad range of social political philosophies with different tendencies and implementation.
Anarchist law primarily deals with how anarchism is implemented
upon a society, the framework based on decentralized organizations and mutual aid, with representation through a form of direct democracy. Laws being based upon their need. A large portion of anarchist ideologies such as anarcho-syndicalism and anarcho-communism primarily focuses on decentralized worker unions, cooperatives and syndicates as the main instrument of society.
Socialist law is the legal systems in communist states such as the former Soviet Union and the People's Republic of China. Academic opinion is divided on whether it is a separate system from civil law, given major deviations based on Marxist–Leninist ideology, such as subordinating the judiciary to the executive ruling party.
In common law legal systems, decisions by courts are explicitly acknowledged as "law" on equal footing with statutes adopted through the legislative process and with regulations issued by the executive branch. The "doctrine of precedent", or stare decisis
(Latin for "to stand by decisions") means that decisions by higher
courts bind lower courts, and future decisions of the same court, to
assure that similar cases reach similar results. In contrast, in "civil law"
systems, legislative statutes are typically more detailed, and judicial
decisions are shorter and less detailed, because the judge or barrister
is only writing to decide the single case, rather than to set out
reasoning that will guide future courts.
Common law originated from England and has been inherited by almost every country once tied to the British Empire (except Malta, Scotland, the U.S. state of Louisiana, and the Canadian province of Quebec). In medieval England, the Norman conquest the law varied-shire-to-shire, based on disparate tribal customs. The concept of a "common law" developed during the reign of Henry II
during the late 12th century, when Henry appointed judges that had
authority to create an institutionalised and unified system of law
"common" to the country. The next major step in the evolution of the
common law came when King John was forced by his barons to sign a document limiting his authority to pass laws. This "great charter" or Magna Carta
of 1215 also required that the King's entourage of judges hold their
courts and judgments at "a certain place" rather than dispensing
autocratic justice in unpredictable places about the country.
A concentrated and elite group of judges acquired a dominant role in
law-making under this system, and compared to its European counterparts
the English judiciary became highly centralised. In 1297, for instance,
while the highest court in France had fifty-one judges, the English Court of Common Pleas had five. This powerful and tight-knit judiciary gave rise to a systematised process of developing common law.
However, the system became overly systematised—overly rigid and
inflexible. As a result, as time went on, increasing numbers of
citizens petitioned the King to override the common law, and on the
King's behalf the Lord Chancellor gave judgment to do what was equitable in a case. From the time of Sir Thomas More, the first lawyer to be appointed as Lord Chancellor, a systematic body of equity grew up alongside the rigid common law, and developed its own Court of Chancery. At first, equity was often criticised as erratic, that it varied according to the length of the Chancellor's foot. Over time, courts of equity developed solid principles, especially under Lord Eldon. In the 19th century in England, and in 1937 in the U.S., the two systems were merged.
In developing the common law, academic writings have always played an important part, both to collect overarching principles from dispersed case law, and to argue for change. William Blackstone, from around 1760, was the first scholar to collect, describe, and teach the common law.
But merely in describing, scholars who sought explanations and
underlying structures slowly changed the way the law actually worked.
Religious law is explicitly based on religious precepts. Examples include the Jewish Halakha and Islamic Sharia—both of which translate as the "path to follow"—while Christian canon law
also survives in some church communities. Often the implication of
religion for law is unalterability, because the word of God cannot be
amended or legislated against by judges or governments. However, a thorough and detailed legal system generally requires human elaboration. For instance, the Quran has some law, and it acts as a source of further law through interpretation, Qiyas (reasoning by analogy), Ijma (consensus) and precedent. This is mainly contained in a body of law and jurisprudence known as Sharia and Fiqh respectively. Another example is the Torah or Old Testament, in the Pentateuch or Five Books of Moses. This contains the basic code of Jewish law, which some Israeli communities choose to use. The Halakha is a code of Jewish law that summarizes some of the Talmud's interpretations. Nevertheless, Israeli law allows litigants to use religious laws only if they choose. Canon law is only in use by members of the Catholic Church, the Eastern Orthodox Church and the Anglican Communion.
A trial in the Ottoman Empire, 1879, when religious law applied under the Mecelle
Until the 18th century, Sharia law was practiced throughout the Muslim world in a non-codified form, with the Ottoman Empire's Mecelle code in the 19th century being a first attempt at codifying
elements of Sharia law. Since the mid-1940s, efforts have been made, in
country after country, to bring Sharia law more into line with modern
conditions and conceptions.
In modern times, the legal systems of many Muslim countries draw upon
both civil and common law traditions as well as Islamic law and custom.
The constitutions of certain Muslim states, such as Egypt and
Afghanistan, recognise Islam as the religion of the state, obliging
legislature to adhere to Sharia. Saudi Arabia recognises Quran as its constitution, and is governed on the basis of Islamic law. Iran has also witnessed a reiteration of Islamic law into its legal system after 1979. During the last few decades, one of the fundamental features of the movement of Islamic resurgence has been the call to restore the Sharia, which has generated a vast amount of literature and affected world politics.
Legal methods
There are distinguished methods of legal reasoning (applying the law)
and methods of interpreting (construing) the law. The former are legal syllogism, which holds sway in civil law legal systems, analogy,
which is present in common law legal systems, especially in the US, and
argumentative theories that occur in both systems. The latter are
different rules (directives) of legal interpretation such as directives
of linguistic interpretation, teleological interpretation or systemic
interpretation as well as more specific rules, for instance, golden rule or mischief rule. There are also many other arguments and cannons of interpretation which altogether make statutory interpretation possible.
Law professor and former United States Attorney GeneralEdward H. Levi
noted that the "basic pattern of legal reasoning is reasoning by
example" - that is, reasoning by comparing outcomes in cases resolving
similar legal questions. In a U.S. Supreme Court case regarding procedural efforts taken by a debt collection company to avoid errors, Justice Sotomayor cautioned that "legal reasoning is not a mechanical or strictly linear process".
Jurimetrics is the formal application of quantitative methods, especially probability and statistics,
to legal questions. The use of statistical methods in court cases and
law review articles has grown massively in importance in the last few
decades.
Legal institutions
It is a real unity of them all in one and the same person, made by
covenant of every man with every man, in such manner as if every man
should say to every man: I authorise and give up my right of governing
myself to this man, or to this assembly of men, on this condition; that
thou givest up, thy right to him, and authorise all his actions in like
manner.
Max Weber
and others reshaped thinking on the extension of state. Modern
military, policing and bureaucratic power over ordinary citizens' daily
lives pose special problems for accountability that earlier writers such
as Locke or Montesquieu could not have foreseen. The custom and
practice of the legal profession is an important part of people's access
to justice,
whilst civil society is a term used to refer to the social
institutions, communities and partnerships that form law's political
basis.
A judiciary is a number of judges mediating disputes to determine
outcome. Most countries have systems of appeal courts, with an apex court as the ultimate judicial authority. In the United States, this authority is the Supreme Court; in Australia, the High Court; in the UK, the Supreme Court; in Germany, the Bundesverfassungsgericht; and in France, the Cour de Cassation.
For most European countries the European Court of Justice in Luxembourg
can overrule national law, when EU law is relevant. The European Court
of Human Rights in Strasbourg allows citizens of the Council of Europe member states to bring cases relating to human rights issues before it.
A judiciary is theoretically bound by the constitution, just as
all other government bodies are. In most countries judges may only interpret
the constitution and all other laws. But in common law countries, where
matters are not constitutional, the judiciary may also create law under
the doctrine of precedent. The UK, Finland and New Zealand assert the ideal of parliamentary sovereignty, whereby the unelected judiciary may not overturn law passed by a democratic legislature.
In communist states,
such as China, the courts are often regarded as parts of the executive,
or subservient to the legislature; governmental institutions and actors
exert thus various forms of influence on the judiciary. In Muslim countries, courts often examine whether state laws adhere to the Sharia: the Supreme Constitutional Court of Egypt may invalidate such laws, and in Iran the Guardian Council ensures the compatibility of the legislation with the "criteria of Islam".
Prominent examples of legislatures are the Houses of Parliament in London, the Congress in Washington D.C., the Bundestag in Berlin, the Duma in Moscow, the Parlamento Italiano in Rome and the Assemblée nationale in Paris. By the principle of representative government people vote for politicians to carry out their wishes. Although countries like Israel, Greece, Sweden and China are unicameral, most countries are bicameral, meaning they have two separately appointed legislative houses.
In the 'lower house' politicians are elected to represent smaller constituencies. The 'upper house' is usually elected to represent states in a federal
system (as in Australia, Germany or the United States) or different
voting configuration in a unitary system (as in France). In the UK the
upper house is appointed by the government as a house of review.
One criticism of bicameral systems with two elected chambers is that
the upper and lower houses may simply mirror one another. The
traditional justification of bicameralism is that an upper chamber acts
as a house of review. This can minimise arbitrariness and injustice in
governmental action.
To pass legislation, a majority of the members of a legislature must vote for a bill (proposed law)
in each house. Normally there will be several readings and amendments
proposed by the different political factions. If a country has an
entrenched constitution, a special majority for changes to the
constitution may be required, making changes to the law more difficult. A
government usually leads the process, which can be formed from Members
of Parliament (e.g. the UK or Germany). However, in a presidential
system, the government is usually formed by an executive and his or her
appointed cabinet officials (e.g. the United States or Brazil).
The G20 meetings are composed of representatives of each country's executive branch.
The executive in a legal system serves as the centre of political authority of the State. In a parliamentary system,
as with Britain, Italy, Germany, India, and Japan, the executive is
known as the cabinet, and composed of members of the legislature. The
executive is led by the head of government, whose office holds power under the confidence
of the legislature. Because popular elections appoint political parties
to govern, the leader of a party can change in between elections.
Although the role of the executive varies from country to
country, usually it will propose the majority of legislation, and
propose government agenda. In presidential systems, the executive often
has the power to veto legislation. Most executives in both systems are
responsible for foreign relations, the military and police, and the bureaucracy. Ministers or other officials head a country's public offices, such as a foreign ministry or defence ministry. The election of a different executive is therefore capable of revolutionising an entire country's approach to government.
While military organisations have existed as long as government
itself, the idea of a standing police force is a relatively modern
concept. For example, Medieval England's system of traveling criminal courts, or assizes, used show trials and public executions to instill communities with fear to maintain control. The first modern police were probably those in 17th-century Paris, in the court of Louis XIV, although the Paris Prefecture of Police claim they were the world's first uniformed policemen.
Max Weber famously argued that the state is that which controls the monopoly on the legitimate use of force. The military and police carry out enforcement at the request of the government or the courts. The term failed state
refers to states that cannot implement or enforce policies; their
police and military no longer control security and order and society
moves into anarchy, the absence of government.
The etymology of bureaucracy derives from the French word for office (bureau) and the Ancient Greek for word power (kratos).
Like the military and police, a legal system's government servants and
bodies that make up its bureaucracy carry out the directives of the
executive. One of the earliest references to the concept was made by Baron de Grimm, a German author who lived in France. In 1765, he wrote:
The real spirit of the laws in France is that bureaucracy
of which the late Monsieur de Gournay used to complain so greatly; here
the offices, clerks, secretaries, inspectors and intendants are
not appointed to benefit the public interest, indeed the public interest
appears to have been established so that offices might exist.
Cynicism over "officialdom" is still common, and the workings of public servants is typically contrasted to private enterprise motivated by profit. In fact private companies, especially large ones, also have bureaucracies. Negative perceptions of "red tape"
aside, public services such as schooling, health care, policing or
public transport are considered a crucial state function making public
bureaucratic action the locus of government power.
Writing in the early 20th century, Max Weber believed that a
definitive feature of a developed state had come to be its bureaucratic
support.
Weber wrote that the typical characteristics of modern bureaucracy are
that officials define its mission, the scope of work is bound by rules,
and management is composed of career experts who manage top down,
communicating through writing and binding public servants' discretion
with rules.
In civil law systems such as those of Italy, France, Germany, Spain and Greece, there is a distinct category of notary, a legally trained public official, compensated by the parties to a transaction. This is a 16th-century painting of such a notary by Flemish painter Quentin Massys.
A corollary of the rule of law is the existence of a legal profession
sufficiently autonomous to invoke the authority of the independent
judiciary; the right to assistance of a barrister
in a court proceeding emanates from this corollary—in England the
function of barrister or advocate is distinguished from legal counselor.
As the European Court of Human Rights has stated, the law should be
adequately accessible to everyone and people should be able to foresee
how the law affects them.
In order to maintain professionalism, the practice of law is typically overseen by either a government or independent regulating body such as a bar association, bar council or law society.
Modern lawyers achieve distinct professional identity through specified
legal procedures (e.g. successfully passing a qualifying examination),
are required by law to have a special qualification (a legal education
earning the student a Bachelor of Laws, a Bachelor of Civil Law, or a Juris Doctor degree. Higher academic degrees may also be pursued. Examples include a Master of Laws, a Master of Legal Studies, a Bar Professional Training Course or a Doctor of Laws.), and are constituted in office by legal forms of appointment (being admitted to the bar). There are few titles of respect to signify famous lawyers, such as Esquire, to indicate barristers of greater dignity, and Doctor of law, to indicate a person who obtained a PhD in Law.
Many Muslim countries have developed similar rules about legal
education and the legal profession, but some still allow lawyers with
training in traditional Islamic law to practice law before personal
status law courts.
In China and other developing countries there are not sufficient
professionally trained people to staff the existing judicial systems,
and, accordingly, formal standards are more relaxed.
Once accredited, a lawyer will often work in a law firm, in a chambers as a sole practitioner, in a government post or in a private corporation as an internal counsel. In addition a lawyer may become a legal researcher
who provides on-demand legal research through a library, a commercial
service or freelance work. Many people trained in law put their skills
to use outside the legal field entirely.
Significant to the practice of law in the common law tradition is
the legal research to determine the current state of the law. This
usually entails exploring case-law reports, legal periodicals and legislation. Law practice also involves drafting documents such as court pleadings, persuasive briefs, contracts, or wills and trusts. Negotiation and dispute resolution skills (including ADR techniques) are also important to legal practice, depending on the field.
The Classical republican concept of "civil society" dates back to Hobbes and Locke.
Locke saw civil society as people who have "a common established law
and judicature to appeal to, with authority to decide controversies
between them." German philosopher Georg Wilhelm Friedrich Hegel distinguished the "state" from "civil society" (bürgerliche Gesellschaft) in Elements of the Philosophy of Right.
Hegel believed that civil society and the state
were polar opposites, within the scheme of his dialectic theory of
history. The modern dipole state–civil society was reproduced in the
theories of Alexis de Tocqueville and Karl Marx.
In post-modern theory, civil society is necessarily a source of law, by
being the basis from which people form opinions and lobby for what they
believe law should be. As Australian barrister and author Geoffrey Robertson QC
wrote of international law, "one of its primary modern sources is found
in the responses of ordinary men and women, and of the non-governmental
organizations which many of them support, to the human rights abuses
they see on the television screen in their living rooms."
Freedom of speech, freedom of association
and many other individual rights allow people to gather, discuss,
criticise and hold to account their governments, from which the basis of
a deliberative democracy
is formed. The more people are involved with, concerned by and capable
of changing how political power is exercised over their lives, the more
acceptable and legitimate
the law becomes to the people. The most familiar institutions of civil
society include economic markets, profit-oriented firms, families, trade
unions, hospitals, universities, schools, charities, debating clubs,
non-governmental organisations, neighbourhoods, churches, and religious
associations. There is no clear legal definition of the civil society,
and of the institutions it includes. Most of the institutions and
bodies who try to give a list of institutions (such as the European Economic and Social Committee) exclude the political parties.
Areas of law
All legal systems deal with the same basic issues, but jurisdictions
categorise and identify their legal topics in different ways. A common
distinction is that between "public law" (a term related closely to the state, and including constitutional, administrative and criminal law), and "private law" (which covers contract, tort and property). In civil law systems, contract and tort fall under a general law of obligations, while trusts law is dealt with under statutory regimes or international conventions. International, constitutional and administrative law, criminal law, contract, tort, property law and trusts are regarded as the "traditional core subjects", although there are many further disciplines.
International law
can refer to three things: public international law, private
international law or conflict of laws and the law of supranational
organisations.
Public international law concerns relationships between sovereign nations. The sources for public international law development are custom, practice and treaties between sovereign nations, such as the Geneva Conventions. Public international law can be formed by international organisations, such as the United Nations (which was established after the failure of the League of Nations to prevent World War II), the International Labour Organisation, the World Trade Organisation, or the International Monetary Fund. Public international law has a special status as law because there is no international police force, and courts (e.g. the International Court of Justice
as the primary UN judicial organ) lack the capacity to penalise
disobedience. The prevailing manner of enforcing international law is
still essentially "self help"; that is the reaction by states to alleged
breaches of international obligations by other states. However, a few bodies, such as the WTO, have effective systems of binding arbitration and dispute resolution backed up by trade sanctions.
Conflict of laws, or private international law in civil law countries, concerns which jurisdiction
a legal dispute between private parties should be heard in and which
jurisdiction's law should be applied. Today, businesses are increasingly
capable of shifting capital and labour
supply chains across borders, as well as trading with overseas
businesses, making the question of which country has jurisdiction even
more pressing. Increasing numbers of businesses opt for commercial
arbitration under the New York Convention 1958.
European Union law is the first and so far the only example of a supranational law, i.e. an internationally accepted legal system, other than the United Nations and the World Trade Organization. Given the trend of increasing global economic integration, many regional agreements—especially the African Union—seek to follow a similar model. In the EU, sovereign nations have gathered their authority in a system of courts and the European Parliament.
These institutions are allowed the ability to enforce legal norms both
against or for member states and citizens in a manner which is not
possible through public international law. As the European Court of Justice noted in its 1963 Van Gend en Loos decision,
European Union law constitutes "a new legal order of international law"
for the mutual social and economic benefit of the member states.
Constitutional and administrative law govern the affairs of the
state. Constitutional law concerns both the relationships between the
executive, legislature and judiciary and the human rights or civil liberties of individuals against the state. Most jurisdictions, like the United States and France, have a single codified constitution with a bill of rights. A few, like the United Kingdom, have no such document. A "constitution" is simply those laws which constitute the body politic, from statute, case law and convention. A case named Entick v Carrington
illustrates a constitutional principle deriving from the common law.
Entick's house was searched and ransacked by Sheriff Carrington. When
Entick complained in court, Sheriff Carrington argued that a warrant
from a Government minister, the Earl of Halifax, was valid authority. However, there was no written statutory provision or court authority. The leading judge, Lord Camden, stated:
The great end, for which men entered into society, was to
secure their property. That right is preserved sacred and
incommunicable in all instances, where it has not been taken away or
abridged by some public law for the good of the whole ... If no excuse
can be found or produced, the silence of the books is an authority
against the defendant, and the plaintiff must have judgment.
The fundamental constitutional principle, inspired by John Locke, holds that the individual can do anything except that which is forbidden by law, and the state may do nothing except that which is authorised by law.
Administrative law is the chief method for people to hold state bodies
to account. People can sue an agency, local council, public service, or
government ministry for judicial review
of actions or decisions, to ensure that they comply with the law, and
that the government entity observed required procedure. The first
specialist administrative court was the Conseil d'État set up in 1799, as Napoleon assumed power in France.
Criminal law, also known as penal law, pertains to crimes and punishment.
It thus regulates the definition of and penalties for offences found to
have a sufficiently deleterious social impact but, in itself, makes no
moral judgment on an offender nor imposes restrictions on society that
physically prevent people from committing a crime in the first place. Investigating, apprehending, charging, and trying suspected offenders is regulated by the law of criminal procedure. The paradigm case of a crime lies in the proof, beyond reasonable doubt, that a person is guilty of two things. First, the accused must commit an act which is deemed by society to be criminal, or actus reus (guilty act). Second, the accused must have the requisite malicious intent to do a criminal act, or mens rea (guilty mind). However, for so called "strict liability" crimes, an actus reus is enough. Criminal systems of the civil law tradition distinguish between intention in the broad sense (dolus directus and dolus eventualis), and negligence. Negligence does not carry criminal responsibility unless a particular crime provides for its punishment.
A depiction of a 17th-century criminal trial, for witchcraft in Salem
Examples of crimes include murder, assault, fraud and theft. In
exceptional circumstances defences can apply to specific acts, such as
killing in self defence, or pleading insanity. Another example is in the 19th-century English case of R v Dudley and Stephens, which tested a defence of "necessity". The Mignonette, sailing from Southampton
to Sydney, sank. Three crew members and Richard Parker, a 17-year-old
cabin boy, were stranded on a raft. They were starving and the cabin boy
was close to death. Driven to extreme hunger, the crew killed and ate
the cabin boy. The crew survived and were rescued, but put on trial for
murder. They argued it was necessary to kill the cabin boy to preserve
their own lives. Lord Coleridge,
expressing immense disapproval, ruled, "to preserve one's life is
generally speaking a duty, but it may be the plainest and the highest
duty to sacrifice it." The men were sentenced to hang, but public opinion was overwhelmingly supportive of the crew's right to preserve their own lives. In the end, the Crown commuted their sentences to six months in jail.
Criminal law offences are viewed as offences against not just individual victims, but the community as well.
The state, usually with the help of police, takes the lead in
prosecution, which is why in common law countries cases are cited as "The People v ..." or "R (for Rex or Regina) v ...". Also, lay juries
are often used to determine the guilt of defendants on points of fact:
juries cannot change legal rules. Some developed countries still condone
capital punishment for criminal activity, but the normal punishment for
a crime will be imprisonment, fines, state supervision (such as probation), or community service. Modern criminal law has been affected considerably by the social sciences, especially with respect to sentencing, legal research, legislation, and rehabilitation. On the international field, 111 countries are members of the International Criminal Court, which was established to try people for crimes against humanity.
Contract law concerns enforceable promises, and can be summed up in the Latin phrase pacta sunt servanda (agreements must be kept). In common law jurisdictions, three key elements to the creation of a contract are necessary: offer and acceptance, consideration and the intention to create legal relations. In Carlill v Carbolic Smoke Ball Company
a medical firm advertised that its new wonder drug, the smokeball,
would cure people's flu, and if it did not, the buyers would get £100.
Many people sued for their £100 when the drug did not work. Fearing
bankruptcy, Carbolic argued the advert was not to be taken as a serious,
legally binding offer. It was an invitation to treat, mere puffery, a gimmick. But the Court of Appeal held that to a reasonable man
Carbolic had made a serious offer, accentuated by their reassuring
statement, "£1000 is deposited". Equally, people had given good
consideration for the offer by going to the "distinct inconvenience" of
using a faulty product. "Read the advertisement how you will, and twist
it about as you will", said Lord Justice Lindley, "here is a distinct promise expressed in language which is perfectly unmistakable".
Consideration indicates the fact that all parties to a contract
have exchanged something of value. Some common law systems, including
Australia, are moving away from the idea of consideration as a
requirement. The idea of estoppel or culpa in contrahendo, can be used to create obligations during pre-contractual negotiations.
Civil law jurisdictions treat contracts differently in a number
of respects, with a more interventionist role for the state in both the
formation and enforcement of contracts.
Compared to common law jurisdictions, civil law systems incorporate
more mandatory terms into contracts, allow greater latitude for courts
to interpret and revise contract terms and impose a stronger duty of good faith, but are also more likely to enforce penalty clauses and specific performance of contracts. They also do not require consideration for a contract to be binding. In France, an ordinary contract is said to form simply on the basis of a "meeting of the minds" or a "concurrence of wills". Germany has a special approach to contracts, which ties into property law. Their 'abstraction principle' (Abstraktionsprinzip)
means that the personal obligation of contract forms separately from
the title of property being conferred. When contracts are invalidated
for some reason (e.g. a car buyer is so drunk that he lacks legal
capacity to contract) the contractual obligation to pay can be invalidated separately from the proprietary title of the car. Unjust enrichment law, rather than contract law, is then used to restore title to the rightful owner.
The "McLibel case" was the longest-running case in UK history. It involved publishing a pamphlet that criticised McDonald's restaurants.
Certain civil wrongs are grouped together as torts under common law systems and delicts under civil law systems.
To have acted tortiously, one must have breached a duty to another
person, or infringed some pre-existing legal right. A simple example
might be accidentally hitting someone with a cricket ball. Under the law of negligence,
the most common form of tort, the injured party could potentially claim
compensation for their injuries from the party responsible. The
principles of negligence are illustrated by Donoghue v Stevenson. A friend of Donoghue ordered an opaque bottle of ginger beer (intended for the consumption of Donoghue) in a café in Paisley.
Having consumed half of it, Donoghue poured the remainder into a
tumbler. The decomposing remains of a snail floated out. She claimed to
have suffered from shock, fell ill with gastroenteritis and sued the
manufacturer for carelessly allowing the drink to be contaminated. The House of Lords decided that the manufacturer was liable for Mrs Donoghue's illness. Lord Atkin took a distinctly moral approach and said:
The liability for negligence [...] is no doubt based upon
a general public sentiment of moral wrongdoing for which the offender
must pay. [...] The rule that you are to love your neighbour becomes in
law, you must not injure your neighbour; and the lawyer's
question, Who is my neighbour? receives a restricted reply. You must
take reasonable care to avoid acts or omissions which you can reasonably
foresee would be likely to injure your neighbour.
This became the basis for the four principles of negligence, namely that (1) Stevenson owed Donoghue a duty of care to provide safe drinks; (2) he breached his duty of care; (3) the harm would not have occurred but for his breach; and (4) his act was the proximate cause of her harm. Another example of tort might be a neighbour making excessively loud noises with machinery on his property. Under a nuisance claim the noise could be stopped. Torts can also involve intentional acts such as assault, battery or trespass. A better known tort is defamation, which occurs, for example, when a newspaper makes unsupportable allegations that damage a politician's reputation. More infamous are economic torts, which form the basis of labour law in some countries by making trade unions liable for strikes, when statute does not provide immunity.
A painting of the South Sea Bubble, one of the world's first ever speculations and crashes, led to strict regulation on share trading.
Property law governs ownership and possession. Real property, sometimes called 'real estate', refers to ownership of land and things attached to it. Personal property, refers to everything else; movable objects, such as computers, cars, jewelry or intangible rights, such as stocks and shares. A right in rem is a right to a specific piece of property, contrasting to a right in personam
which allows compensation for a loss, but not a particular thing back.
Land law forms the basis for most kinds of property law, and is the most
complex. It concerns mortgages, rental agreements, licences, covenants, easements and the statutory systems for land registration. Regulations on the use of personal property fall under intellectual property, company law, trusts and commercial law. An example of a basic case of most property law is Armory v Delamirie [1722]. A chimney sweep's
boy found a jewel encrusted with precious stones. He took it to a
goldsmith to have it valued. The goldsmith's apprentice looked at it,
sneakily removed the stones, told the boy it was worth three halfpence
and that he would buy it. The boy said he would prefer the jewel back,
so the apprentice gave it to him, but without the stones. The boy sued
the goldsmith for his apprentice's attempt to cheat him. Lord Chief Justice Pratt
ruled that even though the boy could not be said to own the jewel, he
should be considered the rightful keeper ("finders keepers") until the
original owner is found. In fact the apprentice and the boy both had a
right of possession in the jewel (a technical concept, meaning evidence that something could
belong to someone), but the boy's possessory interest was considered
better, because it could be shown to be first in time. Possession may be
nine-tenths of the law, but not all.
This case is used to support the view of property in common law
jurisdictions, that the person who can show the best claim to a piece of
property, against any contesting party, is the owner. By contrast, the classic civil law approach to property, propounded by Friedrich Carl von Savigny,
is that it is a right good against the world. Obligations, like
contracts and torts, are conceptualised as rights good between
individuals.
The idea of property raises many further philosophical and political
issues. Locke argued that our "lives, liberties and estates" are our
property because we own our bodies and mix our labour with our surroundings.
Equity is a body of rules that developed in England separately from
the "common law". The common law was administered by judges and
barristers. The Lord Chancellor on the other hand, as the King's keeper of conscience, could overrule the judge-made law if he thought it equitable to do so. This meant equity came to operate more through principles
than rigid rules. Whereas neither the common law nor civil law systems
allow people to split the ownership from the control of one piece of
property, equity allows this through an arrangement known as a trust.
Trustees control property whereas the beneficial, or equitable,
ownership of trust property is held by people known as beneficiaries.
Trustees owe duties to their beneficiaries to take good care of the
entrusted property. In the early case of Keech v Sandford [1722], a child had inherited the lease on a market in Romford,
London. Mr Sandford was entrusted to look after this property until the
child matured. But before then, the lease expired. The landlord had
(apparently) told Mr Sandford that he did not want the child to have the
renewed lease. Yet the landlord was happy (apparently) to give Mr
Sandford the opportunity of the lease instead. Mr Sandford took it. When
the child (now Mr Keech) grew up, he sued Mr Sandford for the profit
that he had been making by getting the market's lease. Mr Sandford was
meant to be trusted, but he put himself in a position of conflict of interest. The Lord Chancellor, Lord King,
agreed and ordered Mr Sandford should disgorge his profits. He wrote:
"I very well see, if a trustee, on the refusal to renew, might have a
lease to himself few trust-estates would be renewed. [...] This may seem
very hard, that the trustee is the only person of all mankind who might
not have the lease; but it is very proper that the rule should be
strictly pursued and not at all relaxed."
Lord King LC was worried that trustees might exploit
opportunities to use trust property for themselves instead of looking
after it. Business speculators using trusts had just recently caused a stock market crash.
Strict duties for trustees made their way into company law and were
applied to directors and chief executive officers. Another example of a
trustee's duty might be to invest property wisely or sell it.
This is especially the case for pension funds, the most important form
of trust, where investors are trustees for people's savings until
retirement. But trusts can also be set up for charitable purposes, famous examples being the British Museum or the Rockefeller Foundation.
Further disciplines
Law spreads far beyond the core subjects into virtually every area of
life. Three categories are presented for convenience, although the
subjects intertwine and overlap.
Labour law is the study of a tripartite industrial relationship between worker, employer and trade union. This involves collective bargaining regulation, and the right to strike. Individual employment law refers to workplace rights, such as job security, health and safety or a minimum wage.
Admiralty law and the sea law
lay a basic framework for free trade and commerce across the world's
oceans and seas, where outside of a country's zone of control. Shipping
companies operate through ordinary principles of commercial law,
generalised for a global market. Admiralty law also encompasses
specialised issues such as salvage, maritime liens, and injuries to passengers.
Intellectual property law aims at safeguarding creators and other producers of intellectual goods and services. These are legal rights (copyrights, trademarks, patents, and related rights) which result from intellectual activity in the industrial, literary and artistic fields.
Restitution deals with the recovery of someone else's gain, rather than compensation for one's own loss.
Unjust enrichment
When someone has been unjustly enriched (or there is an "absence of
basis" for a transaction) at another's expense, this event generates the
right to restitution to reverse that gain.
Space law
is a relatively new field dealing with aspects of international law
regarding human activities in Earth orbit and outer space. While at
first addressing space relations of countries via treaties, increasingly
it is addressing areas such as space commercialisation, property, liability, and other issues.
Banking law and financial regulation
set minimum standards on the amounts of capital banks must hold, and
rules about best practice for investment. This is to insure against the
risk of economic crises, such as the Wall Street Crash of 1929.
Regulation deals with the provision of public services and utilities. Water law is one example. Especially since privatisation
became popular and took management of services away from public law,
private companies doing the jobs previously controlled by government
have been bound by varying degrees of social responsibility. Energy, gas, telecomms and water are regulated industries in most OECD countries.
Competition law, known in the United States as antitrust law, is an evolving field that traces as far back as Roman decrees against price fixing and the English restraint of trade doctrine. Modern competition law derives from the U.S. anti-cartel and anti-monopoly statutes (the Sherman Act and Clayton Act)
of the turn of the 20th century. It is used to control businesses who
attempt to use their economic influence to distort market prices at the
expense of consumer welfare.
Consumer law could include anything from regulations on unfair contractual terms and clauses to directives on airline baggage insurance.
Environmental law is increasingly important, especially in light of the Kyoto Protocol and the potential danger of climate change. Environmental protection also serves to penalise polluters within domestic legal systems.
Aviation law
deals with all regulations and technical standards applicable to the
safe operation of aircraft, and is an essential part both of pilots'
training and pilot's operations. Non adherence to Air Law regulations
and standards renders a flight operation illegal. It is framed by
national civil aviation acts (or laws), themselves mostly aligned with
the recommendations or mandatory standards of the International Civil Aviation Organisation
or ICAO. Regulations are often abbreviated as CARS and standards as
CATS. They constantly evolve in order to adapt to new technologies or
science (for example in medical protocols which pilots have to adhere to
in order to be fit to fly or hold a license).
In the 18th century, Adam Smith presented a philosophical foundation for explaining the relationship between law and economics. The discipline arose partly out of a critique of trade unions and U.S. antitrust law. The most influential proponents, such as Richard Posner and Oliver Williamson and the so-called Chicago School of economists and lawyers including Milton Friedman and Gary Becker, are generally advocates of deregulation and privatisation, and are hostile to state regulation or what they see as restrictions on the operation of free markets.
The most prominent economic analyst of law is 1991 Nobel Prize winner Ronald Coase, whose first major article, The Nature of the Firm (1937), argued that the reason for the existence of firms (companies, partnerships, etc.) is the existence of transaction costs. Rational individuals
trade through bilateral contracts on open markets until the costs of
transactions mean that using corporations to produce things is more
cost-effective. His second major article, The Problem of Social Cost (1960), argued that if we lived in a world without transaction costs, people would bargain with one another to create the same allocation of resources, regardless of the way a court might rule in property disputes. Coase used the example of a nuisance case named Sturges v Bridgman, where a noisy sweetmaker and a quiet doctor were neighbours and went to court to see who should have to move.
Coase said that regardless of whether the judge ruled that the
sweetmaker had to stop using his machinery, or that the doctor had to
put up with it, they could strike a mutually beneficial bargain about
who moves that reaches the same outcome of resource distribution. Only
the existence of transaction costs may prevent this. So the law ought to pre-empt what would happen, and be guided by the most efficient
solution. The idea is that law and regulation are not as important or
effective at helping people as lawyers and government planners believe.
Coase and others like him wanted a change of approach, to put the
burden of proof for positive effects on a government that was
intervening in the market, by analysing the costs of action.
Sociology of law is a diverse field of study that examines the
interaction of law with society and overlaps with jurisprudence,
philosophy of law, social theory and more specialised subjects such as criminology. The institutions of social construction, social norms, dispute processing and legal culture
are key areas for inquiry in this knowledge field. Sociology of law is
sometimes seen as a sub-discipline of sociology, but its ties to the
academic discipline of law are equally strong, and it is best seen as a
transdisciplinary and multidisciplinary study focused on the
theorisation and empirical study of legal practices and experiences as
social phenomena. In the United States the field is usually called law and society
studies; in Europe it is more often referred to as socio-legal studies.
At first, jurists and legal philosophers were suspicious of sociology
of law. Kelsen attacked one of its founders, Eugen Ehrlich,
who sought to make clear the differences and connections between
positive law, which lawyers learn and apply, and other forms of 'law' or
social norms that regulate everyday life, generally preventing
conflicts from reaching barristers and courts.
Contemporary research in sociology of law is much concerned with the
way that law is developing outside discrete state jurisdictions, being
produced through social interaction in many different kinds of social
arenas, and acquiring a diversity of sources of (often competing or
conflicting) authority in communal networks existing sometimes within
nation states but increasingly also transnationally.
Max Weber in 1917, Weber began his career as a lawyer, and is regarded as one of the founders of sociology and sociology of law.
Around 1900 Max Weber
defined his "scientific" approach to law, identifying the "legal
rational form" as a type of domination, not attributable to personal
authority but to the authority of abstract norms.
Formal legal rationality was his term for the key characteristic of the
kind of coherent and calculable law that was a precondition for modern
political developments and the modern bureaucratic state. Weber saw this
law as having developed in parallel with the growth of capitalism. Another leading sociologist, Émile Durkheim, wrote in his classic work The Division of Labour in Society
that as society becomes more complex, the body of civil law concerned
primarily with restitution and compensation grows at the expense of
criminal laws and penal sanctions. Other notable early legal sociologists included Hugo Sinzheimer, Theodor Geiger, Georges Gurvitch and Leon Petrażycki in Europe, and William Graham Sumner in the U.S.
