Amicus curiae
Latin for “friend of the court,” this is a person or entity that is not directly involved in a particular lawsuit but still wants to provide information or advice to the Court about the case. A brief filed by a “friend of the court” is known as an amicus brief.
Appeals court
A court that hears appeals from trial courts. After the appeals court decides a case, it can be appealed to the Supreme Court, which accepts only a tiny fraction of the cases it receives from appeals courts.
Certiorari
Latin term for when the Supreme Court agrees to review the decision of a lower court. When at least four justices agree to hear a case, the Supreme Court grants a “writ of certiorari.”
Circuit
The territory within which a specific court has jurisdiction to hear cases. The federal appeals courts are divided into 12 geographic circuits covering different parts of the country, each with its own court of appeals. The Seventh Circuit Court of Appeals, for example, hears federal cases from Illinois, Indiana, and Wisconsin.
Dissent
A minority opinion that disagrees with a majority court ruling. The dissent doesn’t become the law of land, but it indicates what the justices in the minority were thinking and can influence future decisions.
Docket
A list of legal cases pending before a court. The cases on the Supreme Court docket are those it will consider during its current term.
Judicial activism
The view that Supreme Court justices should reinterpret the Constitution to serve the needs of contemporary society.
Judicial restraint
The view that Supreme Court justices should base their rulings solely on precedents and the law as it is written, rather than trying to second-guess what lawmakers intended or allowing their personal beliefs to affect their decisions.
Jurisdiction
The authority of a court to issue a decision in a particular case.
Petitioner
The person or entity that brings an appeal to the Supreme Court.
Precedent
A previous court decision that judges often rely upon to decide cases involving similar legal questions.
Respondent
The person or entity against which an appeal is brought. This side wants the lower court ruling to be upheld.
Stare decisis
Latin for “to stand by what has been decided.” It’s the underlying concept used in both the American and British legal systems—the idea that the court relies on precedent, or previous court rulings, as the basis for its current decisions.
