Montana District Courts are the state trial courts of general jurisdiction in the U.S. state of Montana.
 Montana District Courts have original jurisdiction over most civil cases (at law and in equity), civil actions involving monetary claims against the state, criminal felony cases, naturalization proceedings, probate cases, and most writs.
 They may also hear certain special actions and proceedings, and oversee a narrowly-defined class of ballot issues.
 Montana District Courts also have limited appellate jurisdiction regarding cases that arise in Justice Courts, City Courts, and Municipal Courts (Courts of Limited Jurisdiction) as well as Judicial review of decisions by state administrative law tribunals that fall under the Montana Administrative Procedures Act.
The Courts for Violence Against Women (Spanish: "Juzgados de Violencia Sobre la Mujer" ) are Specialised criminal courtrooms associated to the Inquiry Courts, established by the Organic Law 1/2004 of Comprehensive Protection Measures against Violence against women.

A ban on sharia law is legislation that would prohibit the application or implementation of Islamic law (sharia) in courts in any civil (non-religious) jurisdiction.

 s of 2014 these include Alabama, Arizona, Kansas, Louisiana, North Carolina, South Dakota and Tennessee.

 In Canada, Sharia law is explicitly banned in Quebec, upheld by a unanimous vote against it in 2005 by the National Assembly, while the province of Ontario allows family law disputes to be arbitrated only under Ontario law.
The manorial courts were the lowest courts of law in England during the feudal period.
 They had a civil jurisdiction limited both in subject matter and geography.
 They dealt with matters over which the lord of the manor had jurisdiction, primarily torts, local contracts and land tenure, and their powers only extended to those who lived within the lands of the manor: the demesne and such lands as the lord had enfeoffed to others, and to those who held land therein.
 Historians have divided manorial courts into those that were primarily seignorial – based on feudal responsibilities – and those based on separate delegation of authority from the monarch.
 There were three types of manorial court: the court of the honour; the court baron; and the court customary, also known as the halmote court.
The Fissile Material Cutoff Treaty (FMCT) is a proposed international treaty to prohibit the further production of fissile material for nuclear weapons or other explosive devices.
 The treaty has not been negotiated and its terms remain to be defined.
 According to a proposal by the United States, fissile material includes high-enriched uranium and plutonium (except plutonium that is over 80% Pu-238).
 According to a proposal by Russia, fissile material would be limited to weapons-grade uranium (with more than 90% U-235) and plutonium (with more than 90% Pu-239).
 Neither proposal would prohibit the production of fissile material for non-weapons purposes, including use in civil or naval nuclear reactors.
The Civil Jurisdiction and Judgments Act 1982 (c.27) is an Act of the Parliament of the United Kingdom, which was passed to implement the Brussels Convention of 1968 into British law.
 As well as governing whether the Courts of England and Wales, Northern Ireland and Scotland have jurisdiction to hear cases against defendants in other contracting states, the Act provided a statutory basis for the division of jurisdiction between the three jurisdictions within the UK.
 No provision was made in 1982 for division of jurisdiction between the UK and Gibraltar; this was rectified by the Civil Jurisdiction and Judgments Act 1982 (Gibraltar) Order 1997 which stated that, for the purposes of the 1982 Act, Gibraltar should be treated as a separate contracting state.
