Court of Last Resort

A court of last resort is the apex judicial body within a legal system: once it rules, the matter is final as a question of domestic law, subject only to constitutional amendment, legislative override (where permitted), or, in some cases, review by a supranational body to which the state has consented.

The label is functional rather than formal. In the United States, the Supreme Court is the court of last resort for federal questions, while each state designates its own — usually called a Supreme Court, though New York confusingly names its highest court the Court of Appeals. In the United Kingdom, the Supreme Court of the United Kingdom has held this role since October 2009, replacing the Appellate Committee of the House of Lords under the Constitutional Reform Act 2005. Germany splits the function across specialized apex courts (the Bundesgerichtshof, Bundesverfassungsgericht, and others), while France divides between the Cour de cassation for ordinary matters and the Conseil d'État for administrative law.

Key characteristics typically include:

• Discretionary docket: many apex courts, like the US Supreme Court via certiorari, choose which cases to hear.
• Binding precedent: rulings bind lower courts within the jurisdiction.
• Constitutional review: in many systems, the court of last resort is also the final interpreter of the constitution, though some states (e.g., Germany, Italy, South Africa) assign this to a separate constitutional court.

For international law, the term is sometimes loosely applied to bodies like the International Court of Justice or the European Court of Human Rights, but these are not strictly courts of last resort — their jurisdiction depends on state consent and they do not sit atop a unified judicial hierarchy. The principle of exhaustion of local remedies, codified in Article 35 of the European Convention on Human Rights, in fact requires applicants to reach their domestic court of last resort before petitioning Strasbourg.
