Law

 ( Main Topic Articles ) 

Law is a set of rules that are created and are law enforcement by 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 as the art of justice. State-enforced laws can be made by a legislature, resulting in ; by the executive through and ; or by judges' decisions, which form precedent in common law jurisdictions. An autocrat may exercise those functions within their realm. 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 also serves as a mediator of relations between people.

Legal systems vary between jurisdictions, with their differences analysed in comparative law. In civil law jurisdictions, a legislature or other central body codifies and consolidates the law. In common law systems, judges may make Legally binding case law through precedent, although on occasion this may be overturned by a higher court or the legislature. Religious law is in use in some religious communities and states, and has historically influenced secular law.

The scope of law can be divided into two domains: public law concerns government and society, including constitutional law, administrative law, and criminal law; while private law deals with legal disputes between parties in areas such as contracts, property, torts, delicts and commercial law. This distinction is stronger in civil law countries, particularly those with a separate system of administrative courts; by contrast, the public-private law divide is less pronounced in common law jurisdictions.

Law provides a source of scholarly inquiry into legal history,

philosophy, economic analysis and sociology.

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.Mc Coubrey, Hilaire and White, Nigel D. Textbook on Jurisprudence. Second Edition. Blackstone Press Limited. 1996. . p. 2. 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.Williams, Glanville. International Law and the Controversy Concerning the Meaning of the Word "Law". Revised version published in Laslett (Editor), Philosophy, Politics and Society (1956) p. 134 et seq. The original was published in (1945) 22 BYBIL 146. 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 Case law").Baron Lloyd of Hampstead. Introduction to Jurisprudence. Third Edition. Stevens & Sons. London. 1972. Second Impression. 1975.

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 describes law as an "interpretive concept" to achieve justice in his text titled Law's Empire; and Joseph Raz argues law is an "authority" to mediate people's interests. Oliver Wendell Holmes defined law as "the prophecies of what the courts will do in fact, and nothing more pretentious."Holmes, Oliver Wendell. "The Path of Law" (1897) 10 Harvard Law Review 457 at 461. In his Treatise on Law, Thomas 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.Aquinas, St Thomas. Summa Theologica. 1a2ae, 90.4. Translated by J G Dawson. Ed d'Entreves. (Basil Blackwell). Latin: "nihil est aliud qau edam rationis ordinatio ad bonum commune, ab eo qi curam communitatis habet, promulgata". This definition has both Legal positivism and Natural law elements.McCoubrey, Hilaire and White, Nigel D. Textbook on Jurisprudence. Second Edition. Blackstone Press Limited. 1996. . p. 73.

Connection to morality and justice Definitions of law often raise the question of the extent to which law incorporates morality. John Austin's utilitarianism answer was that law is "commands, backed by threat of sanctions, from a sovereign, to whom people have a habit of obedience". , on the other hand, 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.

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.Fritz Berolzheimer, The World's Legal Philosophies, 115–116 Immanuel Kant believed a moral imperative requires laws "be chosen as though they should hold as universal laws of nature".Immanuel Kant, Groundwork of the Metaphysics of Morals, 42 (par. 434) Jeremy Bentham and his student Austin, following David Hume, believed that this conflated the Is-ought problem problem. Bentham and Austin argued for law's legal 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".Nietzsche, Zur Genealogie der Moral, Second Essay, 11Kazantzakis, Friedrich Nietzsche and the Philosophy of Law, 97–98Linarelli, Nietzsche in Law's Cathedral, 23–26

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 () 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.Bielefeldt, Carl Schmitt's Critique of Liberalism, 25–26 Therefore, Schmitt advocated a jurisprudence of the exception (state of emergency), which denied that legal norms could encompass all of the political experience.

Later in the 20th century, H. L. A. Hart attacked Austin for his simplifications and Kelsen for his fiction 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 Anglo-American 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 is best left to sociology, rather than jurisprudence.

History The history of law links closely to the development of civilization. law, dating as far back as 3000 BC, was based on the concept of Ma'at and characterised by tradition, speech, social equality and impartiality.VerSteeg, Law in ancient Egypt

(2016). 9780199935390, Oxford University Press. . ISBN 9780199935390

By the 22nd century BC, the ancient ruler Ur-Nammu had formulated the first law code, which consisted of Casuistry statements ("if … then ..."). Around 1760 BC, 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 Stele, 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 Ancient Greece 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 ( nómos) 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 (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 Code 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.

Ancient India and Chinese law 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.For discussion of the composition and dating of these sources, see Olivelle, Manu's Code of Law, 18–25. 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 Hinduism legal tradition, along with Islamic law, were both supplanted by common law when India British Raj 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 Code Civil, 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 Soviet Union Socialist law, which essentially prioritises 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.

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 of many features traditionally considered typical of either common law or civil law. The third type of legal system is religious law, based on . 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.

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 passed by government—and custom. Codifications date back millennia, with one early example being the Babylonian law Codex Hammurabi. Modern civil law systems essentially derive from legal codes issued by Byzantine Empire 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 Empire 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, which scholars at the University of Bologna used to interpret their own laws. Civil law codifications based closely on Roman law, alongside some influences from 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 heavily influenced not only the law systems of the countries in continental Europe but also the Japanese and South Korea legal traditions. A central doctrine in continental European legal thinking, originating in Germany jurisprudence, is the cocpet of a Rechtsstaat, meaning that everyone is subjected to the law, especially governments.Carl Schmitt, The Concept of the Political, ch. 7; Crisis of Parliamentary Democracy Today, countries that have civil law systems range from Russia and Turkey to most of Central America and Latin America.

Common law and equity In common law legal systems, decisions by courts are explicitly acknowledged as "law" on equal footing with legislative Statutory law and executive regulations. The "doctrine of precedent", or stare decisis (Latin for "to stand by decisions") means that decisions by higher courts bind lower courts 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 adjudicator 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 law, and the Canadian province of Quebec law). In medieval England during 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 who had the 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.

As time went on, many felt that the common law was overly systematised and inflexible, and increasing numbers of citizens petitioned the King to override the common law. On the King's behalf, the Lord Chancellor started giving judgments to do what was equitable in a case. From the time of 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.Pollock (ed) Table Talk of John Selden (1927) 43; "Equity is a roguish thing. For law we have a measure... equity is according to the conscience of him that is Chancellor, and as that is longer or narrower, so is equity. 'Tis all one as if they should make the standard for the measure a Chancellor's foot." Over time, courts of equity developed solid principles, especially under Lord Eldon. Gee v Pritchard (1818) 2 Swans. 402, 414 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.Blackstone, Commentaries on the Laws of England, Book the First – Chapter the First But merely in describing, scholars who sought explanations and underlying structures slowly changed the way the law actually worked.

Religious law 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". 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.

(2025). 9781136132506, Routledge. ISBN 9781136132506

Nonetheless, most religious jurisdictions rely on further human elaboration to provide for thorough and detailed legal systems. 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.

A number of countries are sharia jurisdictions. Israeli law allows 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.

Canon law Canon law () is a set of ordinances and regulations made by ecclesiastical authority, for the government of a Christian organisation or church and its members. It is the internal ecclesiastical law governing the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox Churches, and the individual national churches within the Anglican Communion. The way that such church law is legislated, interpreted and at times court varies widely among these three bodies of churches. In all three traditions, a canon was originally a rule adopted by a church council; these canons formed the foundation of canon law.

The Catholic Church has the oldest continuously functioning legal system in the western world,Raymond Wacks, Law: A Very Short Introduction, 2nd Ed. (Oxford University Press, 2015) pg. 13. predating the evolution of modern European civil law and common law systems. The 1983 Code of Canon Law governs the Latin Church Sui iuris. The Eastern Catholic Churches, which developed different disciplines and practices, are governed by the Code of Canons of the Eastern Churches. The canon law of the Catholic Church influenced the common law during the medieval period through its preservation of Roman law doctrine such as the presumption of innocence.Friedman, Lawrence M., American Law: An Introduction (New York: W.W. Norton & Company, 1984), pg. 70.

Roman Catholic canon law is a fully developed legal system, with all the necessary elements: courts, Canon lawyer, judges, a fully articulated legal code, principles of legal interpretation, and coercive penalties, though it lacks civilly-binding force in most secular jurisdictions.

Sharia law 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 the 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 Global politics.

Socialist law Socialist law is the legal systems in 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.

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 General Edward 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.Edward H. Levi, An Introduction to Legal Reasoning (2013), p. 1-2. In a U.S. Supreme Court case regarding procedural efforts taken by a debt collection company to avoid errors, Justice Sonia Sotomayor cautioned that "legal reasoning is not a mechanical or strictly linear process". Jerman v. Carlisle, 130 S.Ct. 1605, 1614, 559 U.S. 573, 587 (2010), Sonia Sotomayor, J.

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 The main institutions of law in industrialised countries are independent courts, representative parliaments, an accountable executive, the military and police, bureaucracy organisation, the legal profession and civil society itself. John Locke, in his Two Treatises of Government, and Baron de Montesquieu in The Spirit of the Laws, advocated for a separation of powers between the political, legislature and executive bodies.Montesquieu, The Spirit of Laws, Book XI: Of the Laws Which Establish Political Liberty, with Regard to the Constitution, Chapters 6–7 Their principle was that no person should be able to usurp all powers of the state, in contrast to the absolutist theory of Thomas Hobbes' Leviathan.Thomas Hobbes, Leviathan, XVII Sun Yat-sen's Five Power Constitution for the Republic of China took the separation of powers further by having two additional branches of government—a Control Yuan for auditing oversight and an Examination Yuan to manage the employment of public officials.

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.

Judiciary

---

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 unicameralism, most countries are bicameralism, meaning they have two separately appointed legislative houses.

In the 'lower house' politicians are elected to represent smaller constituency. The 'upper house' is usually elected to represent states in a Federal republic 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).

---

Executive 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.

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 President of Austria (elected by popular vote). The other important model is the presidential system, 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.Olson, The New Parliaments of Central and Eastern Europe, 7

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 policy, the law enforcement, and the bureaucracy. Ministers or other officials head a country's public offices, such as a Foreign minister or Defence minister. The election of a different executive is therefore capable of revolutionising an entire country's approach to government.

Law enforcement Max Weber famously argued that the state is that which controls the monopoly on the legitimate use of force.Weber, Weber, The Theory of Social and Economic Organisation, 154 The military and police carry out law 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. 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 law, or Assize Court, used and public executions to instill communities with fear to maintain control.See, e.g. Tuberville v Savage (1669), 1 Mod. Rep. 3, 86 Eng. Rep. 684, where a knight said in a threatening tone to a layperson, "If it were not assize time, I would not take such language from you." 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.[

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 private enterprise motivated by profit.Mises, Bureaucracy, II, Bureaucratic Management 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, 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.

Legal profession 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. The Sunday Times v The United Kingdom 1979 ECHR 1 at 49 Case no. 6538/74

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 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.Fine, The Globalisation of Legal Education, 364

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 law report, and legislation. Law practice also involves drafting documents such as court , 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.

Civil society The Classical republican concept of "civil society" dates back to Hobbes and Locke.Warren, Civil Society, 3–4 Locke saw civil society as people who have "a common established law and judicature to appeal to, with authority to decide controversies between them."Locke, , Chap. VII, Of Political or Civil_Society. Chapter 7, section 87 German philosopher Georg Wilhelm Friedrich Hegel distinguished the "state" from "civil society" () in Elements of the Philosophy of Right.Hegel, Elements of the Philosophy of Right, 3, II, 182

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.(Pelczynski, The State and Civil Society, 1–13; Warren, Civil Society, 5–9) 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."Robertson, Crimes Against Humanity, 98–99

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, cogers, 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.Kaldor–Anheier–Glasius, Global Civil Society, passim

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 trust law are regarded as the "traditional core subjects", although there are many further disciplines.

International law

Constitutional and administrative law 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.

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.Locke, The Second Treatise, Tamanaha, On the Rule of Law, 47 Administrative law is the chief method for people to hold state bodies to account. People (wheresoever allowed) may potentially have prerogative to legally challenge (or sue) an agency, local council, public service, or government ministry for judicial review of the offending edict (law, ordinance, policy order). Such challenge vets the ability of actionable authority under 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.

A sub-discipline of constitutional law is election law. It along with Elections commissions, councils, or committees deal with policy and procedures facilitating elections. These rules settle disputes or enable the translation of the will of the people into functioning Democracy. Election law addresses issues who is entitled to Voting, voter registration, ballot access, campaign finance and party funding, redistricting, apportionment, electronic voting and , accessibility of elections, Electoral system and formulas, vote counting, election disputes, , and issues such as electoral fraud and Election silence.

Criminal law Criminal law, also known as penal law, pertains to crimes and punishment.Cesare Beccaria's seminal treatise of 1763–1764 is titled On Crimes and Punishments ( Dei delitti e delle pene). 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.Dennis J. Baker, Glanville Williams Textbook of Criminal Law (London: 2012), 2 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).See e.g. about Robinson v. California, 370 U.S. 660 (1962). 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.See e.g. Feinman, Law 111, 260–261 about Powell v. Texas, 392 U.S. 514 (1968). 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.

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 defense. Another example is in the 19th-century English case of R v Dudley and Stephens, which tested whether a defence of "necessity" could justify murder and cannibalism to survive a shipwreck.About R v Dudley and Stephens 1884 14 QBD 273 DC , see Simpson, Cannibalism and the Common Law, 212–217, 229–237

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 Monarchy or Queen regnant) v ...". Also, lay jury 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 prison, 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.Pelser, Criminal Legislation, 198 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 Contract law concerns enforceable promises, and can be summed up in the Latin phrase pacta sunt servanda (agreements must be kept).Wehberg, Pacta Sunt Servanda, 775 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.

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. Austotel v Franklins (1989) 16 NSWLR 582

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 and specific performance of contracts. They also do not require consideration for a contract to be binding.e.g. in Germany, § 311 Abs. II BGB 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.Smith, The Structure of Unjust Enrichment Law, 1037

Torts and delicts Certain are grouped together as under common law systems and 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 ball. Bolton v Stone 1951 AC 850 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. Donoghue v Stevenson 1932 AC 532, 580

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 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.e.g. concerning a British politician and the Iraq War, George Galloway v Telegraph Group Ltd 2004 EWHC 2786 More infamous are economic torts, which form the basis of labour law in some countries by making trade unions liable for strikes, Taff Vale Railway Co v Amalgamated Society of Railway Servants 1901 AC 426 when statute does not provide immunity.

---

Property law Property law governs ownership and possession. Real property, sometimes called 'real estate', refers to ownership of land and things attached to it.e.g. Hunter v Canary Wharf Ltd 1997 2 All ER 426 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 Mortgage law, Leasehold estate, license, covenants, and the statutory systems for land registration. Regulations on the use of personal property fall under intellectual property, company law, Trust law and commercial law.

A representative example of property law is the 1722 suit of Armory v Delamirie, applying English law. Armory v Delamirie (1722) 93 ER 664, 1 Strange 505 A child was deprived of possession of the gemstones that had been set in piece of jewellery, by the businessperson entrusted to appraise the piece. The court articulated that, according to the view of property in common law jurisdictions, 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.

---

Trusts In historical English law, the common law did not permit dividing the ownership from the control of one piece of property—but the law of equity did recognize 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. Another example of a trustee's duty might be to invest property wisely or sell it. Nestlé v National Westminster Bank plc 1993 1 WLR 1260 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 trust.

Some international norms for the structure and regulation of trusts are set out in the Hague Trust Convention of 1985.

Intersection with other fields

Economics 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 prominent economic analyst of law is 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 . Homo economicus 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 with one another to create the same allocation of resources, regardless of the way a court might rule in property disputes. He contended that law ought to be pre-emptive, and be guided by the most efficient solution.

Many members of the so-called Chicago School are generally advocates of deregulation and privatisation, and are hostile to state regulation or what they see as restrictions on the operation of .

Sociology The sociology of law examines the interaction of law with society and overlaps with jurisprudence, philosophy of law, social theory and more specialised subjects such as criminology. It is a transdisciplinary and multidisciplinary study focused on the theorisation and empirical study of legal practices and experiences as social phenomena. The institutions of social construction, social norms, dispute processing and legal culture are key areas for inquiry in this knowledge field. 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 lawyers and courts.Ehrlich, Fundamental Principles, Hertogh, Living Law, Rottleuthner, La Sociologie du Droit en Allemagne, 109, Rottleuthner, Rechtstheoritische Probleme der Sociologie des Rechts, 521 Contemporary research in the sociology of law is concerned with the way that law develops outside discrete state jurisdictions, being produced through social interaction in social arenas, and acquiring a diversity of sources of authority in national and transnational communal networks.

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 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.
