Philosophy of law

The philosophy of law is commonly known as jurisprudence. Normative jurisprudence asks "what should law be?", while analytic jurisprudence asks "what is law?"


Analytical jurisprudence

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. Dennis Lloyd, Baron Lloyd of Hampstead. ''Introduction to Jurisprudence''. Third Edition. Stevens & Sons. London. 1972. Second Impression. 1975. p. 39. McCoubrey and White said that the question "what is law?" has no simple answer.
Glanville Williams Glanville Llewelyn Williams (15 February 1911 – 10 April 1997) was a Welsh legal scholar who was the Rouse Ball Professor of English Law at the University of Cambridge from 1968 to 1978 and the Quain Professor of Jurisprudence at University ...

" 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,'' H.L.A Hart argued that law is a "system of rules"; John Austin said law was "the command of a sovereign, backed by the threat of a sanction";
Ronald Dworkin Ronald Myles Dworkin (; December 11, 1931 – February 14, 2013) was an American philosopher, jurist, and scholar of United States constitutional law. At the time of his death, he was Frank Henry Sommer Professor of Law and Philosophy at New Yo ...

Connection to morality and justice

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".Bix
John Austin
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 ''

, 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".

; 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

), which denied that legal norms could encompass all of the political experience.Finn, ''Constitutions in Crisis'', 170–171 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'',

attacked Hart and the positivists for their refusal to treat law as a moral issue. Dworkin argues that law is an " interpretive concept",Law's Empire, 410" /> 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, ''The Authority of Law'', 3–36 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.

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.

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 enslaved people. 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.As a legal system, Roman law has affected the development of law worldwide. It also forms the basis for the law codes of most countries of continental Europe and has played an important role in the creation of the idea of a common European culture (Stein, ''Roman Law in European History'', 2, 104–107). Although codes were replaced by custom and

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

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.


Legal systems

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.Mattei, ''Comparative Law and Economics'', 71 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

. 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

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

'' Codex 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

Socialist law is the legal systems in communist states such as the former Soviet Union and the People's Republic of China.

" 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

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

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.

Legislature

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

, meaning they have two separately appointed legislative houses.Riker, ''The Justification of Bicameralism'', 101 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

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).


Executive

The executive in a legal system serves as the centre of political
authority In the fields of sociology and political science, authority is the legitimate power of a person or group over other people. In a civil state, ''authority'' is practiced in ways such a judicial branch or an executive branch of government.''The N ...
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.Haggard, ''Presidents, Parliaments and Policy'', 71 The head of state is apart from the executive, and symbolically enacts laws and acts as representative of the nation. Examples include the President of Germany (appointed by members of federal and state legislatures), the Queen of the United Kingdom (an hereditary office), and the

, found in the United States and in Brazil. In presidential systems, the executive acts as both head of state and head of government, and has power to appoint an unelected cabinet. Under a presidential system, the executive branch is separate from the legislature to which it is not accountable. 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

. The election of a different executive is therefore capable of revolutionising an entire country's approach to government.


Military and police

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 travelling criminal courts, or
assizes The courts of assize, or assizes (), were periodic courts held around England and Wales until 1972, when together with the quarter sessions they were abolished by the Courts Act 1971 and replaced by a single permanent Crown Court. The assizes e ...

famously argued that the state is that which controls the monopoly on the legitimate use of force.Weber, Politics as a Vocation 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.


Bureaucracy

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

" 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, ''Economy and Society'', I, 393 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.

Civil society

The
Classical republican Classical republicanism, also known as civic republicanism or civic humanism, is a form of republicanism developed in the Renaissance inspired by the governmental forms and writings of classical antiquity, especially such classical writers as Ar ...
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."

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.

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

Criminal law

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.Brody, Acker and Logan, ''Criminal Law'', 2; Wilson, ''Criminal Law'', 2 Investigating, apprehending, charging, and trying suspected offenders is regulated by the law of

Negligence does not carry criminal responsibility unless a particular crime provides for its punishment. 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.

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".About

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.

s 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 unintentionally 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''.'' Donoghue v Stevenson'' ( 932A.C. 532, 1932 S.C. (H.L.) 31, [1932All ER Rep 1">932.html" ;"title="932A.C. 532, 1932 S.C.

A friend of Donoghue ordered an opaque bottle of ginger beer (intended for the consumption of Donoghue) in a café in Paisley, Renfrewshire, 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

'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.'' Sturges v Bridgman'' (1879) 11 Ch D 852 Under a nuisance claim the noise could be stopped. Torts can also involve intentional acts such as

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,

. An example of a basic case of most property law is '' Armory v Delamirie'' 722 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 Sir John Pratt (1657–1725) was an English judge and politician. He was Lord Chief Justice of England from 15 May 1718 until 2 March 1725. He was appointed as an interim Chancellor of the Exchequer on 2 February 1721 until 3 April 1721. Life ...
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 and trusts

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'' 722 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 A conflict of interest (COI) is a situation in which a person or organization is involved in multiple interests, financial or otherwise, and serving one interest could involve working against another. Typically, this relates to situations i ...
. 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

, 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 in Economics, 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. Homo economicus, 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 bargaining, 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 efficiency (economics), 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

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.Cotterrell, ''Sociology of Law'', Jary, ''Collins Dictionary of Sociology'', 636 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. Around 1900
Max Weber Maximilian Karl Emil Weber (; ; 21 April 186414 June 1920) was a German sociologist, historian, jurist and political economist, who is regarded as among the most important theorists of the development of modern Western society. His ideas profo ...
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.Papachristou, ''Sociology of Law'', 81–82
