The “doctrine of precedent”, or stare decisis (Latin for “to stand by decisions”) means that decisions by higher courts bind lower courts, and future decisions of the same court, to assure that similar cases reach similar results. This case is used to support the view of property in common law jurisdictions, that the person who can show the best claim to a piece of property, against any contesting party, is the owner. By contrast, the classic civil law approach to property, propounded by Friedrich Carl von Savigny, is that it is a right good against the world. Obligations, like contracts and torts, are conceptualised as rights good between individuals. The idea of property raises many further philosophical and political issues.

In the United States the field is usually called Law News 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. 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. 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’ means that the personal obligation of contract forms separately from the title of property being conferred.

According to Malloy , Smith established “a classical liberal philosophy that made individuals the key referential sign while acknowledging that we live not alone but in community with others”. Richard Posner, University of Chicago Law School professor and the most cited legal scholar, until 2014 ran a blog with Nobel Prize winning economist Gary Becker. Competition law, known in the United States as antitrust law, is an evolving field that traces as far back as Roman decrees against price fixing and the English restraint of trade doctrine. Modern competition law derives from the U.S. anti-cartel and anti-monopoly statutes of the turn of the 20th century.

They constantly evolve in order to adapt to new technologies or science . Environmental law is increasingly important, especially in light of the Kyoto Protocol and the potential danger of climate change. Environmental protection also serves to penalise polluters within domestic legal systems.

This is mainly contained in a body of law and jurisprudence known as Sharia and Fiqh respectively. Another example is the Torah or Old Testament, in the Pentateuch or Five Books of Moses. This contains the basic code of Jewish law, which some Israeli communities choose to use. The Halakha is a code of Jewish law that summarizes some of the Talmud’s interpretations. Nevertheless, Israeli law allows litigants to use religious laws only if they choose.

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). A judiciary is theoretically bound by the constitution, just as all other government bodies are. In most countries judges may only interpret the constitution and all other laws. But in common law countries, where matters are not constitutional, the judiciary may also create law under the doctrine of precedent. The UK, Finland and New Zealand assert the ideal of parliamentary sovereignty, whereby the unelected judiciary may not overturn law passed by a democratic legislature.
