The Calcutta High Court is the oldest High Court in India. It is located at Esplanade Row West, Kolkata, West Bengal. It has jurisdiction over the state of West Bengal and the Union Territory of the Andaman and Nicobar Islands. The High Court building's design is somewhat based on the Lakenhal in Ypres in Flanders, Belgium.

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.
