89-583: Law is a set of rules that are created and are enforceable 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 statutes ; by the executive through decrees and regulations ; 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

178-401: 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

267-644: 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

356-687: A ruler ') 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

445-440: 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

534-464: A case. From the time of Sir Thomas More , the first lawyer to be appointed as Lord Chancellor, a systematic body of equity grew up alongside the rigid common law, and developed its own Court of Chancery . At first, equity was often criticised as erratic. 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. ,

623-441: 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

712-414: 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 ,

801-598: A process of reform, at least in terms of economic, if not social and political, rights. A new contract code in 1999 represented a move away from administrative domination. Furthermore, after negotiations lasting fifteen years, in 2001 China joined the World Trade Organization . In general, legal systems can be split between civil law and common law systems. Modern scholars argue that the significance of this distinction has progressively declined. The numerous legal transplants , typical of modern law, result in

890-586: A wide variety of non-criminal violations of rules and norms, effected through the imposition of less severe consequences such as probation. Law enforcement organizations existed in ancient times, such as prefects in ancient China , paqūdus in Babylonia , curaca in the Inca Empire , vigiles in the Roman Empire , and Medjay in ancient Egypt . Who law enforcers were and reported to depended on

979-459: Is legislated , interpreted and at times adjudicated 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 , predating the evolution of modern European civil law and common law systems. The 1983 Code of Canon Law governs

1068-499: Is a code of Jewish law that summarizes some of the Talmud's interpretations. A number of countries are sharia jurisdictions. Israeli law allows litigants to use religious laws only if they choose. Canon law is only in use by members of the Catholic Church , the Eastern Orthodox Church and the Anglican Communion . Canon law ( Ancient Greek : κανών , romanized :  kanon , lit.   'a straight measuring rod;

1157-767: Is a national police agency, which supervises the police agencies for each individual prefecture ; and in Niger , there is a national police for urban areas and a gendarmerie for rural areas, both technically national-level. In some cases, there may be multiple agencies at the same level but with different focuses: for example, in the United States, the Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives are both national-level federal law enforcement agencies, but

1246-458: 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

1335-468: 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." 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. This definition has both positivist and naturalist elements. Definitions of law often raise

1424-509: 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. The history of law links closely to the development of civilization . Ancient Egyptian law, dating as far back as 3000 BC, was based on the concept of Ma'at and characterised by tradition, rhetorical speech, social equality and impartiality. By

1513-459: Is autonomous or dependent on other organizations for its operations, the governing body that funds and oversees the agency may decide to dissolve or consolidate its operations. Dissolution of an agency may occur when the governing body or the agent itself decides to end operations. This can occur due to multiple reasons, including criminal justice reform , a lack of population in the jurisdiction, mass resignations , efforts to deter corruption , or

1602-438: Is defined in opposition to international law . It encompasses the laws enacted by national, state , or local governments and is concerned with regulating the behavior of individuals, corporations, and entities within the country. Municipal law includes various branches such as criminal law , private law , administrative law , and constitutional law . It is enforced by domestic courts and administrative bodies. Municipal law

1691-465: Is law?" There have been several attempts to produce "a universally acceptable definition of law". In 1972, Baron Hampstead suggested that no such definition could be produced. McCoubrey and White said that the question "what is law?" has no simple answer. Glanville Williams said that the meaning of the word "law" depends on the context in which that word is used. He said that, for example, " early customary law " and " municipal law " were contexts where

1780-533: 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 . Law also raises important and complex issues concerning equality, fairness, and justice . The word law , attested in Old English as lagu , comes from

1869-515: Is tailored to the unique needs, values, and circumstances of the specific political entity it governs. For instance, traffic regulations, criminal codes , and property laws are all examples of municipal laws that vary from one country to another. Article 27 of the Vienna Convention on the Law of Treaties from 1969 provides that if a treaty conflicts with a state's municipal law (including

1958-437: 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

2047-1056: Is the Supreme Court ; in Australia, the High Court ; in India, the Supreme Court of India ; in the UK, the Supreme Court ; in Germany, the Bundesverfassungsgericht ; and in France, the Cour de Cassation . For most European countries the European Court of Justice in Luxembourg can overrule national law, when EU law is relevant. The European Court of Human Rights in Strasbourg allows citizens of

2136-486: Is the legal systems in communist states such as the former Soviet Union and the People's Republic of China . Academic opinion is divided on whether it is a separate system from civil law, given major deviations based on Marxist–Leninist ideology, such as subordinating the judiciary to the executive ruling party. There are distinguished methods of legal reasoning (applying the law) and methods of interpreting (construing)

2225-566: Is to make laws, since they are acts of the general will ; nor whether the prince is above the law, since he is a member of the State; nor whether the law can be unjust, since no one is unjust to himself; nor how we can be both free and subject to the laws, since they are but registers of our wills. Jean-Jacques Rousseau, The Social Contract , II, 6. The philosophy of law is commonly known as jurisprudence. Normative jurisprudence asks "what should law be?", while analytic jurisprudence asks "what

2314-697: The Manusmriti (c. 100–300 AD) were foundational treatises in India, and comprise texts considered authoritative legal guidance. Manu's central philosophy was tolerance and pluralism , and was cited across Southeast Asia. During the Muslim conquests in the Indian subcontinent , sharia was established by the Muslim sultanates and empires, most notably Mughal Empire 's Fatawa-e-Alamgiri , compiled by emperor Aurangzeb and various scholars of Islam. In India,

2403-455: The "is" and what "ought to be" problem. Bentham and Austin argued for law's positivism ; that real law is entirely separate from "morality". Kant was also criticised by Friedrich Nietzsche , who rejected the principle of equality, and believed that law emanates from the will to power , and cannot be labeled as "moral" or "immoral". In 1934, the Austrian philosopher Hans Kelsen continued

2492-503: The Codex Hammurabi . The most intact copy of these stelae was discovered in the 19th century by British Assyriologists , and has since been fully transliterated and translated into various languages, including English, Italian, German, and French. The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society. The small Greek city-state, ancient Athens , from about

2581-610: The Council of Europe member states to bring cases relating to human rights issues before it. Some countries allow their highest judicial authority to overrule legislation they determine to be unconstitutional . For example, in Brown v. Board of Education , the United States Supreme Court nullified many state statutes that had established racially segregated schools, finding such statutes to be incompatible with

2670-486: 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

2759-592: 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

2848-1248: 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 Korean legal traditions. Today, countries that have civil law systems range from Russia and Turkey to most of Central and Latin America . In common law legal systems, decisions by courts are explicitly acknowledged as "law" on equal footing with legislative statutes 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

2937-570: The Fourteenth Amendment to the United States Constitution . A judiciary is theoretically bound by the constitution, just as all other government bodies are. In most countries judges may only interpret the constitution and all other laws. But in common law countries, where matters are not constitutional, the judiciary may also create law under the doctrine of precedent . The UK, Finland and New Zealand assert

3026-666: The French , but mostly the German Civil Code. This partly reflected Germany's status as a rising power in the late 19th century. Similarly, traditional Chinese law gave way to westernisation towards the final years of the Qing Dynasty in the form of six private law codes based mainly on the Japanese model of German law. Today Taiwanese law retains the closest affinity to the codifications from that period, because of

3115-536: The Hindu legal tradition, along with Islamic law, were both supplanted by common law when India became part of the British Empire . Malaysia, Brunei, Singapore and Hong Kong also adopted the common law system. The Eastern Asia legal tradition reflects a unique blend of secular and religious influences. Japan was the first country to begin modernising its legal system along Western lines, by importing parts of

3204-676: The Latin Church sui juris . 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 . Roman Catholic canon law is a fully developed legal system, with all

3293-478: The Old Norse word lǫg . The singular form lag meant ' something laid or fixed ' while its plural meant ' law ' . But what, after all, is a law? [...] When I say that the object of laws is always general, I mean that law considers subjects en masse and actions in the abstract, and never a particular person or action. [...] On this view, we at once see that it can no longer be asked whose business it

3382-621: 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

3471-679: The absolutist theory of Thomas Hobbes ' Leviathan . 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

3560-656: The s hurta , and the Maréchaussée provided services ranging from law enforcement and personal protection to customs enforcement and waste collection. In England , a complex law enforcement system emerged, where tithings , groups of ten families, were responsible for ensuring good behavior and apprehending criminals; groups of ten tithings ("hundreds") were overseen by a reeve ; hundreds were governed by administrative divisions known as shires ; and shires were overseen by shire-reeves . In feudal Japan , samurai were responsible for enforcing laws. The concept of police as

3649-595: The "basic pattern of legal reasoning is reasoning by example"—that is, reasoning by comparing outcomes in cases resolving similar legal questions. In a U.S. Supreme Court case regarding procedural efforts taken by a debt collection company to avoid errors, Justice Sotomayor cautioned that "legal reasoning is not a mechanical or strictly linear process". Jurimetrics is the formal application of quantitative methods, especially probability and statistics , to legal questions. The use of statistical methods in court cases and law review articles has grown massively in importance in

The Province of Carolina established slave-catcher patrols in the 1700s, and by 1785, the Charleston Guard and Watch was reported to have the duties and organization of a modern police force. The first municipal police department in the United States was the Philadelphia Police Department , while the first American state police , federal law enforcement agency

3827-937: The 1749 establishment of the London Bow Street Runners , the first formal police force in Britain. In 1800, Napoleon reorganized French law enforcement to form the Paris Police Prefecture ; the British government passed the Glasgow Police Act , establishing the City of Glasgow Police ; and the Thames River Police was formed in England to combat theft on the River Thames . In September 1829, Robert Peel merged

3916-644: The 19th century, improvements in technology, greater global connections, and changes in the sociopolitical order led to the establishment of police forces worldwide. National, regional, and municipal civilian law enforcement agencies exist in practically all countries; to promote their international cooperation, the International Criminal Police Organization , also known as Interpol, was formed in September 1923. Technology has made an immense impact on law enforcement, leading to

4005-424: The 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code , which consisted of casuistic statements ("if … then ..."). Around 1760 BC, King Hammurabi further developed Babylonian law , by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae , for the entire public to see; this became known as

4094-471: 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

4183-428: 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

4272-889: The Bow Street Runners and the Thames River Police to form the Metropolitan Police . The title of the "first modern police force" has still been claimed by the modern successors to these organizations. Following European colonization of the Americas , the first law enforcement agencies in the Thirteen Colonies were the New York Sheriff's Office and the Albany County Sheriff's Department , both formed in

4361-728: The DEA focuses on narcotics crimes, while the ATF focuses on weapon regulation violations. Various segments of society may have their own specialist law enforcement agency , such as the military having military police , schools having school police or campus police , or airports having airport police . Private police may exist in some jurisdictions, often to provide dedicated law enforcement for privately-owned property or infrastructure, such as railroad police for private railways or hospital police for privately-owned hospital campuses. Depending on various factors, such as whether an agency

4450-492: 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,

4539-507: 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 world politics . Socialist law

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

4717-468: 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 , and the Canadian province of Quebec ). In medieval England during the Norman conquest , the law varied shire-to-shire based on disparate tribal customs. The concept of

Aside from their duties to enforce laws, many ancient law enforcers also served as slave catchers , firefighters , watchmen , city guards , and bodyguards . By the post-classical period and the Middle Ages , forces such as the Santa Hermandades ,

4895-506: The defining features of any legal system. Civil law is the legal system used in most countries around the world today. In civil law the sources recognised as authoritative are, primarily, legislation —especially codifications in constitutions or statutes passed by government—and custom . Codifications date back millennia, with one early example being the Babylonian Codex Hammurabi . Modern civil law systems essentially derive from legal codes issued by Byzantine Emperor Justinian I in

4984-575: The development and regular use of police cars , police radio systems, police aviation , police tactical units , and police body cameras . Most law enforcement is conducted by some law enforcement agency , typically a police force. Civilians generally staff police agencies, which are typically not a military branch . However, some militaries do have branches that enforce laws among the civilian populace, often called gendarmerie , security forces , or internal troops . Social investment in enforcement through such organizations can be massive in terms of

5073-428: 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

5162-597: 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 religious laws such as canon law , continued to spread throughout Europe until

5251-411: The governing body contracting with a different agency that renders the original agency redundant or obsolete. According to the International Association of Chiefs of Police , agency consolidation can occur to improve efficiency, consolidate resources, or when forming a new type of government. Municipal law Municipal law is the national, domestic, or internal law of a sovereign state and

5340-469: The idea of the rule of law because he did not accept the primacy of abstract normative principles over concrete political positions and decisions. Therefore, Schmitt advocated a jurisprudence of the exception ( state of emergency ), which denied that legal norms could encompass all of the political experience. 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

5429-426: The ideal of parliamentary sovereignty , whereby the unelected judiciary may not overturn law passed by a democratic legislature. In communist states , such as China, the courts are often regarded as parts of the executive, or subservient to the legislature; governmental institutions and actors exert thus various forms of influence on the judiciary. In Muslim countries, courts often examine whether state laws adhere to

5518-562: The last few decades. It is a real unity of them all in one and the same person, made by covenant of every man with every man, in such manner as if every man should say to every man: I authorise and give up my right of governing myself to this man, or to this assembly of men, on this condition; that thou givest up, thy right to him, and authorise all his actions in like manner. Thomas Hobbes, Leviathan , XVII The main institutions of law in industrialised countries are independent courts , representative parliaments, an accountable executive,

5607-475: The law more difficult. A government usually leads the process, which can be formed from Members of Parliament (e.g. the UK or Germany). However, in a presidential system, the government is usually formed by an executive and his or her appointed cabinet officials (e.g. the United States or Brazil). The 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,

5696-614: The law. In common law systems, judges may make 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

5785-686: 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

5874-446: 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

5963-426: The legal profession is an important part of people's access to justice , whilst civil society is a term used to refer to the social institutions, communities and partnerships that form law's political basis. A judiciary is a number of judges mediating disputes to determine outcome. Most countries have systems of appeal courts, with an apex court as the ultimate judicial authority. In the United States, this authority

6052-469: 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

6141-411: The military and police, bureaucratic 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. Their principle was that no person should be able to usurp all powers of the state , in contrast to

6230-499: The military and police, and the bureaucracy. Ministers or other officials head a country's public offices, such as a foreign ministry or defence ministry . The election of a different executive is therefore capable of revolutionising an entire country's approach to government. Law enforcement The concept of law enforcement dates back to ancient times, and forms of law enforcement and police have existed in various forms across many human societies. Modern state legal codes use

6319-611: 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 China represent distinct traditions of law, and have historically had independent schools of legal theory and practice. The Arthashastra , probably compiled around 100 AD (although it contains older material), and

6408-701: 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

6497-511: The necessary elements: courts , lawyers , judges, a fully articulated legal code, principles of legal interpretation, and coercive penalties, though it lacks civilly-binding force in most secular jurisdictions. 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

Hugo Grotius , the founder of a purely rationalistic system of natural law, argued that law arises from both a social impulse—as Aristotle had indicated—and reason. Immanuel Kant believed a moral imperative requires laws "be chosen as though they should hold as universal laws of nature". Jeremy Bentham and his student Austin, following David Hume , believed that this conflated

6675-569: 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 ' ( German : Grundnorm ) instructing us to obey. Kelsen's major opponent, Carl Schmitt , rejected both positivism and

6764-488: 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

6853-665: The primary law enforcement organization originated in Europe in the early modern period ; the first statutory police force was the High Constables of Edinburgh in 1611, while the first organized police force was the Paris lieutenant général de police in 1667. Until the 18th century, law enforcement in England was mostly the responsibility of private citizens and thief-takers , albeit also including constables and watchmen. This system gradually shifted to government control following

6942-415: The principle of representative government people vote for politicians to carry out their wishes. Although countries like Israel, Greece, Sweden and China are unicameral , most countries are bicameral , meaning they have two separately appointed legislative houses. In the 'lower house' politicians are elected to represent smaller constituencies . The 'upper house' is usually elected to represent states in

7031-467: The question of the extent to which law incorporates morality. John Austin 's utilitarian answer was that law is "commands, backed by threat of sanctions, from a sovereign, to whom people have a habit of obedience". Natural lawyers , on the other 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

7120-742: The resources invested in the activity and the number of people professionally engaged to perform those functions. Law enforcement agencies are limited to operating within a specified jurisdiction . These are typically organized into three basic levels: national, regional, and municipal. However, depending on certain factors, there may be more or less levels, or they may be merged: in the United States, there are federal , state , and local police and sheriff agencies; in Canada, some territories may only have national-level law enforcement, while some provinces have national, provincial, and municipal; in Japan , there

7209-400: 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 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

7298-457: 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 Socialist law , which essentially prioritises administrative law at the expense of private law rights. Due to rapid industrialisation, today China is undergoing

7387-418: The term law enforcement officer or peace officer to include every person vested by the legislating state with police power or authority; traditionally, anyone sworn or badged who can arrest any person for a violation of criminal law is included under the umbrella term of law enforcement. Although law enforcement may be most concerned with the prevention and punishment of crimes, organizations exist to discourage

7476-418: 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

7565-619: The way the law actually worked. Religious law is explicitly based on religious precepts. Examples include the Jewish Halakha and Islamic Sharia —both of which translate as the "path to follow". 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. Nonetheless, most religious jurisdictions rely on further human elaboration to provide for thorough and detailed legal systems. For instance,

7654-415: 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

7743-495: Was formed so that merchants could trade with common standards of practice rather than with the many splintered facets of local laws. The Law Merchant, a precursor to modern commercial law, emphasised the freedom to contract and alienability of property. As nationalism grew in the 18th and 19th centuries, the Law Merchant was incorporated into countries' local law under new civil codes. The Napoleonic and German Codes became

7832-404: 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

7921-752: Was the United States Marshals Service , both formed in 1789. In the American frontier , law enforcement was the responsibility of county sheriffs , rangers , constables , and marshals . The first law enforcement agency in Canada was the Royal Newfoundland Constabulary , established in 1729, while the first Canadian national law enforcement agency was the Dominion Police , established in 1868.
