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 group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions. Private individuals may create legally binding contracts, including arbitration agreements that adopt alternative ways of resolving disputes to standard court litigation. 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 binding case law through precedent, although on occasion this may be overturned by a higher court or the legislature. Historically, religious law has influenced secular matters and is, as of the 21st century, still in use in some religious communities. Sharia law based on Islamic principles is used as the primary legal system in several countries, including Iran and Saudi Arabia.

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.

Royal assent is the method by which a monarch formally approves an act of the legislature, either directly or through an official acting on the monarch's behalf. In some jurisdictions, royal assent is equivalent to promulgation, while in others that is a separate step. Under a modern constitutional monarchy, royal assent is considered little more than a formality. Even in nations such as the United Kingdom, Norway, the Netherlands, Liechtenstein and Monaco which still, in theory, permit their monarch to withhold assent to laws, the monarch almost never does so, except in a dire political emergency or on advice of government. While the power to veto by withholding royal assent was once exercised often by European monarchs, such an occurrence has been very rare since the eighteenth century.

Royal assent is typically associated with elaborate ceremony. In the United Kingdom the Sovereign may appear personally in the House of Lords or may appoint Lords Commissioners, who announce that royal assent has been granted at a ceremony held at the Palace of Westminster for this purpose. However, royal assent is usually granted less ceremonially by letters patent. In other nations, such as Australia, the governor-general (as the Monarch's representative) has the right to dissolve the parliament and to sign a bill. In Canada, the governor general may give assent either in person at a ceremony in the Senate or by a written declaration notifying Parliament of their agreement to the bill. (Full article...)

Selected biography

Earl Warren as Chief Justice of the Supreme Court

Earl Warren (March 19, 1891 – July 9, 1974) was an American lawyer, politician, and jurist who served as the 30th governor of California from 1943 to 1953 and as the 14th Chief Justice of the United States from 1953 to 1969. The Warren Court presided over a major shift in American constitutional jurisprudence, which has been recognized by many as a "Constitutional Revolution" in the liberal direction, with Warren writing the majority opinions in landmark cases such as Brown v. Board of Education (1954), Reynolds v. Sims (1964), Miranda v. Arizona (1966), and Loving v. Virginia (1967). Warren also led the Warren Commission, a presidential commission that investigated the 1963 assassination of President John F. Kennedy. He previously served as Governor of California from 1943 to 1953. Warren is generally considered to be one of the most influential Supreme Court justices and political leaders in the history of the United States.

Warren served as Thomas E. Dewey's running mate in the 1948 presidential election, but the ticket lost the election to incumbent President Harry S. Truman and Senator Alben W. Barkley in an election upset. Warren sought the Republican nomination in the 1952 presidential election, but the party nominated General Dwight D. Eisenhower. After Eisenhower won election as president, he appointed Warren as Chief Justice. A series of rulings made by the Warren Court in the 1950s helped lead to the decline of McCarthyism. Warren helped arrange a unanimous decision in Brown v. Board of Education (1954), which ruled that racial segregation in public schools was unconstitutional. After Brown, the Warren Court continued to issue rulings that helped bring an end to the segregationist Jim Crow laws that were prevalent throughout the Southern United States. In Heart of Atlanta Motel, Inc. v. United States (1964), the Court upheld the Civil Rights Act of 1964, a federal law that prohibits racial segregation in public institutions and public accommodations.

In the 1960s, the Warren Court handed down several landmark rulings that significantly transformed criminal procedure, redistricting, and other areas of the law. Many of the Court's decisions incorporated the Bill of Rights, making the protections of the Bill of Rights apply to state and local governments. Gideon v. Wainwright (1963) established a criminal defendant's right to an attorney in felony cases, and Miranda v. Arizona (1966) required police officers to give what became known as the Miranda warning to suspects taken into police custody that advises them of their constitutional protections. Reynolds v. Sims (1964) established that all state legislative districts must be of roughly equal population size, while the Court's holding in Wesberry v. Sanders (1964) required equal populations for congressional districts, thus achieving "one man, one vote" in the United States. Schmerber v. California (1966) established that forced extraction of a blood sample is not compelled testimony, illuminating the limits on the protections of the 4th and 5th Amendments and Warden v. Hayden (1967) dramatically expanded the rights of police to seize evidence with a search warrant, reversing the mere evidence rule. Furthermore, Griswold v. Connecticut (1965) established a constitutional right to privacy and struck down a state law that restricted access to contraceptives, and Loving v. Virginia (1967) struck down state anti-miscegenation laws, which had banned or otherwise regulated interracial marriage. Warren announced his retirement in 1968 and was succeeded by Appellate Judge Warren E. Burger in 1969. The Warren Court's rulings have received criticism, but have received widespread support and acclamation from both liberals and conservatives. As yet, few of the Court's decisions have been overturned. (Full article...)

Selected statute

A statute is a formal written enactment of a legislative body, a stage in the process of legislation. Typically, statutes command or prohibit something, or declare policy. Statutes are laws made by legislative bodies; they are distinguished from case law or precedent, which is decided by courts, regulations issued by government agencies, and oral or customary law.[better source needed] Statutes may originate with the legislative body of a country, state or province, county, or municipality.

The Occupiers' Liability Act 1957 (5 & 6 Eliz. 2. c. 31) is an Act of the Parliament of the United Kingdom that covers occupiers' liability. The result of the Third Report of the Law Reform Committee, the Act was introduced to Parliament as the Occupiers' Liability Bill and granted royal assent on 6 June 1957, coming into force on 1 January 1958. The Act unified several classes of visitors to property and the duty of care owed to them by the occupier, as well as codifying elements of the common law relating to this duty of care. It also covered the duty owed to parties to a contract entering the property and ways of excluding the liability for visitors. The Act introduced an element of liability for landlords who failed to maintain their properties and were as a result responsible for the injury of a non-tenant, something counter to the previous common law rule in English law. The Act is still valid law, and forms much of the law relating to occupiers' liability in English law along with the Occupiers' Liability Act 1984. (Full article...)

Selected case

Case law, also used interchangeably with common law, is a law that is based on precedents, that is the judicial decisions from previous cases, rather than law based on constitutions, statutes, or regulations. Case law uses the detailed facts of a legal case that have been resolved by courts or similar tribunals. These past decisions are called "case law", or precedent. Stare decisis—a Latin phrase meaning "let the decision stand"—is the principle by which judges are bound to such past decisions, drawing on established judicial authority to formulate their positions.

Roe v. Wade, 410 U.S. 113 (1973), was a landmark decision of the U.S. Supreme Court in which the Court ruled that the Constitution of the United States generally protected a right to have an abortion. The decision struck down many abortion laws, and caused an ongoing abortion debate in the United States about whether, or to what extent, abortion should be legal, who should decide the legality of abortion, and what the role of moral and religious views in the political sphere should be. The decision also shaped debate concerning which methods the Supreme Court should use in constitutional adjudication.

The case was brought by Norma McCorvey—under the legal pseudonym "Jane Roe"—who, in 1969, became pregnant with her third child. McCorvey wanted an abortion but lived in Texas, where abortion was illegal except when necessary to save the mother's life. Her lawyers, Sarah Weddington and Linda Coffee, filed a lawsuit on her behalf in U.S. federal court against her local district attorney, Henry Wade, alleging that Texas's abortion laws were unconstitutional. A special three-judge court of the U.S. District Court for the Northern District of Texas heard the case and ruled in her favor. The parties appealed this ruling to the Supreme Court. In January 1973, the Supreme Court issued a 7–2 decision in McCorvey's favor holding that the Due Process Clause of the Fourteenth Amendment to the United States Constitution provides a fundamental "right to privacy", which protects a pregnant woman's right to an abortion. It also held that the right to abortion is not absolute and must be balanced against the government's interests in protecting women's health and prenatal life. It resolved these competing interests by announcing a pregnancy trimester timetable to govern all abortion regulations in the United States. The Court also classified the right to abortion as "fundamental", which required courts to evaluate challenged abortion laws under the "strict scrutiny" standard, the most stringent level of judicial review in the United States.

The Supreme Court's decision in Roe was among the most controversial in U.S. history. In addition to the dissent, Roe was criticized by some in the legal community, including some who thought that Roe reached the correct result but went about it the wrong way, and some called the decision a form of judicial activism. Others argued that Roe did not go far enough, as it was placed within the framework of civil rights rather than the broader human rights. The decision also radically reconfigured the voting coalitions of the Republican and Democratic parties in the following decades. Anti-abortion politicians and activists sought for decades to restrict abortion or overrule the decision; polls into the 21st century showed that a plurality and a majority, especially into the late 2010s to early 2020s, opposed overruling Roe. Despite criticism of the decision, the Supreme Court reaffirmed Roe's central holding in its 1992 decision, Planned Parenthood v. Casey. Casey overruled Roe's trimester framework and abandoned its "strict scrutiny" standard in favor of an "undue burden" test. (Full article...)
