An amicus curiae (also spelled amicus curiæ; plural amici curiae) is someone, not a party to a case, who volunteers to offer information to assist a court in deciding a matter before it. The information provided may be a legal opinion in the form of a brief (which is called an amicus brief when offered by an amicus curiae), a testimony that has not been solicited by any of the parties, or a learned treatise on a matter that bears on the case. The decision on whether to admit the information lies at the discretion of the court. The phrase amicus curiae is legal Latin and literally means "friend of the court".

The amicus curiae figure originates in Roman law. Starting in the 9th century, it was incorporated to English law, and was later extended to most of common law systems. Later, it was also introduced in international law, in particular concerning human rights. From there, it was integrated in some civil law systems (it has recently been integrated in Argentina). Today, it is used by the European Court of Human Rights, the Inter-American Commission on Human Rights, the Inter-American Court of Human Rights and the Court of Justice of European Union.
The role of an amicus is often confused with that of an intervener. The role of an amicus is, as stated by Salmon LJ (as Lord Salmon then was) in Allen v Sir Alfred McAlpine & Sons Ltd [1968] 2 QB 229 at p. 266 F-G:
The situation most often noted in the press is when an advocacy group files a brief in a case before an appellate court to which it is not a litigant. Appellate cases are normally limited to the factual record and arguments coming from the lower court case under appeal; attorneys focus on the facts and arguments most favorable to their clients. Where a case may have broader implications, amicus curiae briefs are a way to introduce those concerns, so that the possibly broad legal effects of court decisions will not depend solely on the parties directly involved in the case.
In prominent cases, amici curiae are generally organizations with sizable legal budgets. Non-profit legal advocacy organizations such as the American Civil Liberties Union, the Landmark Legal Foundation, the Electronic Frontier Foundation, the American Center for Law and Justice or NORML frequently submit such briefs to advocate for or against a particular legal change or interpretation. If a decision could affect an entire industry, companies other than the litigants may wish to have their concerns heard. In the United States, federal courts often hear cases involving the constitutionality of state laws. Hence states themselves may file briefs as amici curiae when their laws are likely to be affected, as in the Supreme Court case McDonald v. Chicago when thirty-two states under the aegis of Texas (and California independently) filed such briefs.[1]
Amici curiae that do not file briefs often present an academic perspective on the case. For example, if the law gives deference to a history of legislation of a certain topic, a historian may choose to evaluate the claim using their expertise. An economist, statistician, or sociologist may choose to do the same. Blogs, newspaper editorials, and other opinion pieces arguably have the capability to influence Supreme Court decisions as de facto amici curiae.[2][3] They are not, however, considered as an actual amicus curiae in the sense that they do not submit materials to the Court, do not need to ask for leave, and have no guarantee that they will be read.
The Supreme Court of the United States has special rules for amicus curiae briefs, covered generally by Supreme Court Rule 37. The Rule states, in part, such a brief should cover "relevant matter" not dealt with by the parties which "may be of considerable help".[4] The cover of an amicus brief must identify which party the brief is supporting or if the brief only supports affirmance or reversal. Supreme Court Rule 37.3(a). The Court, inter alia, also requires that all non-governmental Amici identify those providing a monetary contribution to the preparation or submission of the brief. Supreme Court Rule 37.6. Briefs must be prepared in booklet format and 40 copies must be served with the Court.[5]
In general, unless the amicus brief is being filed by the federal government (or one of its officers or agents) or a U.S. state, permission of the court (by means of motion for leave) or mutual consent of the parties is required. Allowing an amicus curiae to present oral argument is considered "extraordinary".[6]
