for: List of national supreme courts

A supreme court, also called a court of last resort or high court, is in some jurisdictions the highest judicial body within that jurisdiction's court system, whose rulings are not subject to further review by another court. The designations for such courts differ among jurisdictions. Courts of last resort typically function primarily as appellate courts, hearing appeals from the lower trial courts or intermediate-level appellate courts.

The main power for the Judicial Branch is to consider appeals from state courts, rather than just federal courts...

Many countries in fact have multiple "supreme courts," with each being the court of last resort for a particular geographical region or on a particular area of law. The United States, having a federal system of government, has a single Supreme Court of the United States, but each U.S. state furthermore has its own high court over which the U.S. Supreme Court only has jurisdiction on issues of federal law. Other jurisdictions follow the Austrian model of a separate constitutional court (first developed in the Czechoslovak constitution and Austrian Constitution of 1920). Furthermore, in e.g. Finland, Sweden, Czech republic and Poland, there is a separate Supreme Administrative Court whose decisions are final and whose jurisdiction does not overlap with the Supreme Court. The U.S. states of Texas and Oklahoma also divide subject matter jurisdiction among two separate courts of last resort, with one hearing criminal cases and the other civil cases.

Many higher courts create through their decisions case law applicable within their respective jurisdictions or interpret codal provisions in civil law countries to maintain a uniform interpretation:

• Most common law nations have the doctrine of stare decisis in which the previous rulings (decisions) of a court constitute binding precedent upon the same court or courts of lower status within their jurisdiction.

• Most civil law nations do not have the official doctrine of stare decisis and hence the rulings of the supreme court are usually not binding outside the immediate case in question. However, in practice, the precedent, or jurisprudence constante, expressed by those courts is often extremely strong. Some exceptions such as Spain are discussed below.

Australia

In Australia, the High Court of Australia became the court of last resort with the passing of the Australia Act in 1986. This act abolished the last rights of appeal to the Privy Council. Each state and territory has its own Supreme Court, which is the highest court in that state/territory. This leads to some confusion among those from other jurisdictions as the term "supreme court" seems to refer to the court of last resort. The reason that the High Court of Australia is not named the "supreme court" is purely historical. Before the federation of the Australian colonies as states of Australia (in 1901), each colony had its own independent judicial system with a supreme court as the highest court physically within the colony (with a right of appeal to the Privy Council). On federation, the constitution provided for the establishment of the 'High Court' which could hear appeals from the state Supreme Courts. With the exception of The Australian Capital Territory, each state's Supreme Court are divided into two divisions: The Trial Division and The Court of Appeals. Appeals from The ACT Supreme Court are heard in The High Court Justice of Australia. The current Chief Justice is Murray Gleeson.
