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.

Insanity in English law is a defence to criminal charges based on the idea that the defendant was unable to understand what he was doing, or, that he was unable to understand that what he was doing was wrong.

The defence comes in two forms; where the defendant claims he was insane at the time of the crime, and where the defendant asserts he is insane at the time of trial. In the first situation, the defendant must show that he was either suffering from a disease which damaged the functioning of the mind and led to a defect of reason that prevented him from understanding what he was doing, or that he could not tell that what he was doing was wrong. In the second situation, the test is whether or not the defendant can differentiate between "guilty" and "not guilty" verdicts, instruct counsel and recognise the charges he is facing. If successful, he is likely to be detained under the Criminal Procedure (Insanity) Act 1964, although judges have a wide discretion as to what to do.

Use of insanity as a concept dates from 1324, and its criminal application was used until the late 16th century in an almost identical way. The defence, if successful, either allowed the defendant to return home or led to him being incarcerated until he was granted a royal pardon; after 1542, a defendant who became insane prior to the trial could not be tried for any crime, up to and including high treason. During the 18th century the test to determine insanity became extremely narrow, with defendants required to prove that they could not distinguish between good and evil and that they suffered from a mental disease which made them incapable of understanding the consequences of their actions. The current wording comes from the M'Naghten Rules, based on the trial of Daniel M'Naghten in 1843. (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 Defective Premises Act 1972 (c. 35) is an act of the Parliament of the United Kingdom that covers landlords' and builders' liability for poorly constructed and poorly maintained buildings, along with any injuries that may result. During the 19th century, the common law principle that a landlord could not be liable for letting a poorly maintained house was established, while a long-running principle was that, in practice, builders could not be sued for constructing defective buildings. The courts began to turn against the first principle during the 20th century, imposing several restrictions on the landlord's immunity, but the landlord was still largely free from being sued.

The Defective Premises Bill was introduced to the House of Commons as a private member's bill by Ivor Richard on 1 December 1971, and given the royal assent on 29 June 1972, coming into force as the Defective Premises Act 1972 on 1 January 1974. The act establishes a duty of care builders and their sub-contractors owe to the occupiers of property they construct or modify, and also establishes a duty of care landlords hold towards their tenants and any third parties who might be injured by their failure to maintain or repair property. The act received a mixed reaction from critics; while some complimented it on its simple nature compared to the previously complex common rule laws, others felt that it was too limited for what was desired to be achieved, and that the wording used was at times both too vague and too specific.

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.

The Smith Act trials of Communist Party leaders in New York City from 1949 to 1958 were the result of US federal government prosecutions in the postwar period and during the Cold War between the Soviet Union and the United States. Leaders of the Communist Party of the United States (CPUSA) were accused of violating the Smith Act, a statute that prohibited advocating violent overthrow of the government. The defendants argued that they advocated a peaceful transition to socialism, and that the First Amendment's guarantee of freedom of speech and of association protected their membership in a political party. Appeals from these trials reached the US Supreme Court, which ruled on issues in Dennis v. United States (1951) and Yates v. United States (1957).

The first trial of eleven communist leaders was held in New York in 1949; it was one of the lengthiest trials in United States history. Numerous supporters of the defendants protested outside the courthouse on a daily basis. The trial was featured twice on the cover of Time magazine. The defense frequently antagonized the judge and prosecution; five defendants were jailed for contempt of court because they disrupted the proceedings. The prosecution's case relied on undercover informants, who described the goals of the CPUSA, interpreted communist texts, and testified of their own knowledge that the CPUSA advocated the violent overthrow of the US government.

While the first trial was under way, events outside the courtroom influenced public perception of communism: the Soviet Union tested its first nuclear weapon, and communists prevailed in the Chinese Civil War. In this period, the House Un-American Activities Committee (HUAC) had also begun conducting investigations and hearings of writers and producers in Hollywood suspected of communist influence. Public opinion was overwhelmingly against the defendants in New York. After a 10-month trial, the jury found all 11 defendants guilty. The judge sentenced them to terms of up to five years in federal prison, and sentenced all five defense attorneys to imprisonment for contempt of court. Two of the attorneys were subsequently disbarred. (Full article...)
