The Supreme Court of India is the supreme judicial authority and the highest court of the Republic of India. It is the final court of appeal for all civil and criminal cases in India. It also has the power of judicial review. The Supreme Court, which consists of the Chief Justice of India and a maximum of fellow 33 judges, has extensive powers in the form of original, appellate and advisory jurisdictions.

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.
