The high courts of India are the highest courts of appellate jurisdiction in each state and union territory of India. However, a high court exercises its original civil and criminal jurisdiction only if the subordinate courts are not authorized by law to try such matters for lack of peculiar or territorial jurisdiction. High courts may also enjoy original jurisdiction in certain matters, if so designated, especially by the constitution, a state law or union law.
The work of most high courts primarily consists of adjudicating on appeals from lower courts and writ petitions in terms of Articles 226 and 227 of the Constitution. Writ jurisdiction is also the original jurisdiction of a high court.
