The Federal Constitutional Court is the supreme constitutional court for the Federal Republic of Germany, established by the constitution or Basic Law of Germany. Since its inception with the beginning of the post-World War II republic, the court has been located in the city of Karlsruhe, which is also the seat of the Federal Court of Justice.

In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, and high court of appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are binding on all other courts in a nation and are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. A Supreme Court can also, in certain circumstances, act as a court of original jurisdiction, however, this is typically limited to constitutional law.
