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.

Scientific jury selection, often abbreviated SJS, is the use of social science techniques and expertise to choose favorable juries during a criminal or civil trial. Scientific jury selection is used during the jury selection phase of the trial, during which lawyers have the opportunity to question jurors. It almost always entails an expert's assistance in the attorney's use of peremptory challenges—the right to reject a certain number of potential jurors without stating a reason—during jury selection. The practice is currently unique to the American legal system.

SJS has roots in criminal trials during the Vietnam War era, but in modern times is usually employed in high-stakes civil litigation (where only money is usually at issue, in contrast to criminal trials, where the defendant can go to prison). SJS practitioners determine what background characteristics and attitudes predict favorable results, and then coordinate with attorneys in choosing the jury. Studies are mixed as to the effectiveness of the practice, though it is clear that the evidence presented at trial is the most important determiner of verdicts (the trial result) and that SJS is more likely to have an impact where that evidence is ambiguous. SJS's potential to unfairly skew the jury has led to some reform proposals, but none have yet been implemented. (Full article...)

Selected biography

A black and white photograph of Birkett

William Norman Birkett, 1st Baron Birkett, PC (6 September 1883 – 10 February 1962), was a British barrister, judge, politician and preacher who served as the deputy British judge during the Nuremberg Trials.

Birkett received his education at Barrow-in-Furness Higher Grade School. He was a Methodist preacher and a draper before attending Emmanuel College, Cambridge, in 1907, to study theology, history and law. Upon graduating in 1910 he worked as a secretary and was called to the Bar in 1913.

Declared medically unfit for military service during World War I, Birkett used the time to make up for his late entry into the legal profession and was appointed a King's Counsel in 1924. He became a criminal defence lawyer and acted as counsel in a number of famous cases including the second of the Brighton trunk murders. A member of the Liberal Party, he sat in Parliament for Nottingham East twice, first in 1923 and again in 1929.

Despite refusing appointment to the High Court of Justice in 1928, he was offered the position again in 1941 and accepted, joining the King's Bench Division. In 1945 he served as the alternate British judge at the Nuremberg trials, and he was made a privy counsellor in 1947. He joined the Court of Appeal in 1950 but retired in 1956 when he had served for long enough to draw a pension. From 1958 he served in the House of Lords, and his speech against a private bill in 1962 (the Bill sought to convert the Cumbrian lake Ullswater into a reservoir) saw it defeated by 70 votes to 36, two days before he died on 10 February 1962.

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.

Hours of service (HOS) regulations are issued by the Federal Motor Carrier Safety Administration (FMCSA) and govern the working hours of anyone operating a commercial motor vehicle (CMV) in the United States. These regulations apply to truck drivers, commercial and intercity bus drivers, and school bus drivers who operate CMVs. These rules limit the number of daily and weekly hours spent driving and working, and regulate the minimum amount of time drivers must spend resting between driving shifts. For intrastate commerce, the respective state's regulations apply.

The HOS's main purpose is to prevent accidents caused by driver fatigue. This is accomplished by limiting the number of driving hours per day, and the number of driving and working hours per week. Fatigue is also prevented by keeping drivers on a 21- to 24-hour schedule, maintaining a natural sleep/wake cycle (or circadian rhythm). Drivers are required to take a daily minimum period of rest, and are allowed longer "weekend" rest periods to combat cumulative fatigue effects that accrue on a weekly basis. (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.

Public Prosecutor v. Taw Cheng Kong is a landmark case decided in 1998 by the Court of Appeal of Singapore which shaped the landscape of Singapore's constitutional law. The earlier High Court decision, Taw Cheng Kong v. Public Prosecutor, was the first instance in Singapore's history that a statutory provision was struck down as unconstitutional. The matter subsequently reached the Court of Appeal when the Public Prosecutor applied for a criminal reference for two questions to be considered. The questions were:

  1. whether section 37(1) of the Prevention of Corruption Act (Cap. 241, 1993 Rev. Ed.) ("PCA") was ultra vires the powers of the legislature on the ground that the legislature had, under section 6(3) of the Republic of Singapore Independence Act 1965 (No. 9 of 1965, 1985 Rev. Ed.), been divested of the power to legislate extraterritorially; and
  2. whether section 37(1) of the PCA was discriminatory against Singapore citizens and hence inconsistent with Article 12(1) of the Constitution of the Republic of Singapore (1992 Reprint) (now the Singapore Constitution (1999 Reprint)).

In answering both questions in the negative, the Court of Appeal overturned the High Court's finding that the statute was unconstitutional. The Court of Appeal further clarified Singapore's stance on legislative plenary power and expounded upon Article 12(1) of the Constitution, explaining that the promise of equality does not mean that all persons are to be treated equally, but simply that all persons in like situations will be treated alike. Drawing on foreign case law, the Court of Appeal further outlined the test to determine if a differentiating law falls foul of Article 12. (Full article...)
