In law, common law is the body of law created by judges and similar quasi-judicial tribunals by virtue of being stated in written opinions.
Precedent is a principle or rule established in a legal case that becomes authoritative to a court or other tribunal when deciding subsequent cases with similar legal issues or facts. The legal doctrine stating that courts should follow precedent is called stare decisis.
Procedural law, adjective law, in some jurisdictions referred to as remedial law, or rules of court, comprises the rules by which a court hears and determines what happens in civil, lawsuit, criminal or administrative proceedings. The rules are designed to ensure a fair and consistent application of due process or fundamental justice to all cases that come before a court.
English law is the common law legal system of England and Wales, comprising mainly criminal law and civil law, each branch having its own courts and procedures.
In law, certiorari is a court process to seek judicial review of a decision of a lower court or government agency. Certiorari comes from the name of an English prerogative writ, issued by a superior court to direct that the record of the lower court be sent to the superior court for review. The term is Latin for "to be made more certain", and comes from the opening line of such writs, which traditionally began with the Latin words "Certiorari volumus...".
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.
Justiciability concerns the limits upon legal issues over which a court can exercise its judicial authority. It includes, but is not limited to, the legal concept of standing, which is used to determine if the party bringing the suit is a party appropriate to establishing whether an actual adversarial issue exists. Essentially, justiciability seeks to address whether a court possesses the ability to provide adequate resolution of the dispute; where a court believes that it cannot offer such a final determination, the matter is not justiciable.

An advisory opinion is an opinion issued by a court or a commission like an election commission that does not have the effect of adjudicating a specific legal case, but merely advises on the constitutionality or interpretation of a law. Some countries have procedures by which the executive or legislative branches may certify important questions to the judiciary and obtain an advisory opinion. In other countries or specific jurisdictions, courts may be prohibited from issuing advisory opinions.

Sosa v. Alvarez-Machain, 542 U.S. 692 (2004), was a United States Supreme Court case involving the Alien Tort Statute and the Federal Tort Claims Act. Many ATS claims were filed after the Second Circuit ruling in Filártiga v. Peña-Irala created a new common law cause of action for torture under the ATS: "For purposes of civil liability, the torturer has become—like the pirate and slave trader before him—hostis humani generis, an enemy of all mankind." The Court in Sosa does not find there is a similar cause of action for arbitrary arrest and detention. They wrote that finding new common law causes of action based on international norms would require "a substantial element of discretionary judgment", and explain that the role of common law has changed since ATS was enacted meaning the Court will "look for legislative guidance before exercising innovative authority over substantive law".
A contract is an agreement that specifies certain legally enforceable rights and obligations pertaining to two or more parties. A contract typically involves the transfer of goods, services, money, or a promise to transfer any of those at a future date, and the activities and intentions of the parties entering into a contract may be referred to as contracting. In the event of a breach of contract, the injured party may seek judicial remedies such as damages or equitable remedies such as specific performance or rescission. A binding agreement between actors in international law is known as a treaty.
Constitutional avoidance is a legal doctrine of judicial review in United States constitutional law that dictates that United States federal courts should refuse to rule on a constitutional issue if the case can be resolved without involving constitutionality. In Ashwander v. Tennessee Valley Authority (1936), the Supreme Court of the United States established a seven-rule test for the justiciability of controversies presenting constitutional questions:
- Collusive lawsuit rule: The Court will not [rule] upon the constitutionality of legislation in a friendly, nonadversary, proceeding, declining because to decide such questions "is legitimate only in the last resort, and as a necessity in the determination of real, earnest and vital controversy between individuals. It never was the thought that, by means of a friendly suit, a party beaten in the legislature could transfer to the courts an inquiry as to the constitutionality of the legislative act."
- Ripeness: The Court will not "anticipate a question of constitutional law in advance of the necessity of deciding it."
- Minimalism: The Court will not "formulate a rule of constitutional law broader than is required by the precise facts to which it is to be applied."
- Last resort rule: The Court will not [rule] upon a constitutional question, although properly presented by the record, if there is also present some other ground upon which the case may be disposed of. ... [I]f a case can be decided on either of two grounds, one involving a constitutional question, the other a question of statutory construction or general law, the Court will decide only the latter.
- Standing; Mootness: The Court will not [rule] upon the validity of a statute upon complaint of one who fails to show that he is injured by its operation.
- Constitutional estoppel: The Court will not [rule] upon the constitutionality of a statute at the instance of one who has availed himself of its benefits.
- Constitutional avoidance canon: "When the validity of an act of the Congress is drawn in question, and even if a serious doubt of constitutionality is raised, it is a cardinal principle that this Court will first ascertain whether a construction of the statute is fairly possible by which the question may be avoided."
Threshold issues are legal requirements in Singapore administrative law that must be satisfied by applicants before their claims for judicial review of acts or decisions of public authorities can be dealt with by the High Court. These include showing that they have standing to bring cases, and that the matters are amenable to judicial review and justiciable by the Court.
Pacific States Telephone & Telegraph Co. v. Oregon, 223 U.S. 118 (1912), was a decision of the Supreme Court of the United States involving the constitutionality of the citizens' initiative and the enforceability of the Guarantee Clause of the Constitution. In an opinion authored by Chief Justice Edward Douglass White, a unanimous Court rejected a corporation's argument that the Guarantee Clause forbade Oregon's initiative process, citing Luther v. Borden to conclude that such claims presented political questions and thus were non-justiciable.
