Both these codes influenced heavily not only the law systems of the countries in continental Europe (e.g. Greece), but also the Japanese and Korean legal traditions. Today, countries that have civil law systems range from Russia and Turkey to most of Central and Latin America. Sociology of law is a diverse field of study that examines the interaction of law with society and overlaps with jurisprudence, philosophy of law, social theory and more specialised subjects such as criminology. The institutions of social construction, social norms, dispute processing and legal culture are key areas for inquiry in this knowledge field.

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 exclude the political parties. In civil law systems such as those of Italy, France, Germany, Spain and Greece, there is a distinct category of notary, a legally trained public official, compensated by the parties to a transaction. This is a 16th-century painting of such a notary by Flemish painter Quentin Massys.

  • To pass legislation, a majority of the members of a legislature must vote for a bill in each house.
  • Anarchist law primarily deals with how anarchism is implemented upon a society, the framework based on decentralized organizations and mutual aid, with representation through a form of direct democracy.
  • Law and commerceCompany law sprang from the law of trusts, on the principle of separating ownership of property and control.
  • 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”).
  • Pitt Law provides a world-class legal education; advances and transforms the law and our society; serves and partners with communities; and develops and manages resources sustainably.

Furthermore, after negotiations lasting fifteen years, in 2001 China joined the World Trade Organization. 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.


When contracts are invalidated for some reason (e.g. a car buyer is so drunk that he lacks legal capacity to contract) the contractual obligation to pay can be invalidated separately from the proprietary title of the car. Unjust enrichment law, rather than contract law, is then used to restore title to the rightful owner. The main institutions of law in industrialised countries are independent courts, representative parliaments, an accountable executive, 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 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.

Legal profession

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”). Access leading legal scholars in policy and research, attend in-depth seminars and conferences/symposia by renowned experts, and learn from respected practitioners.

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 , and the Manusmriti (c. 100–300 AD) were foundational treatises in India, and comprise texts considered authoritative legal guidance.

If a country has an entrenched constitution, a special majority for changes to the constitution may be required, making changes to the Law News 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). Constitution, U.S. laws, rules or regulations, or a treaty signed by the U.S., and the federal courts have exclusive jurisdiction, then the case must be litigated in federal court. Pitt’s Center for International Legal Education advances legal education and the rule of law throughout the world. One-year master’s degree programs and a doctoral degree for international graduate students who have earned a law degree outside the United States.

The use of statistical methods in court cases and law review articles has grown massively in importance in the last few decades. 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.

His state constitutional law research has been cited by the New Jersey Supreme Court, and his research into constitutional change has been cited by leading scholars in law reviews, textbooks, and academic journals. Professor Marshfield has also served as a consultant to foreign officials regarding issues of constitutional revision, and he has advised public policy groups regarding voter awareness and ballot issues. There are distinguished methods of legal reasoning and methods of interpreting 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 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.

Examples include the Jewish Halakha and Islamic Sharia—both of which translate as the “path to follow”—while Christian canon law also survives in some church communities. Often the implication of religion for law is unalterability, because the word of God cannot be amended or legislated against by judges or governments. However, a thorough and detailed legal system generally requires human elaboration.
