British India's three presidency towns of Madras (Chennai), Bombay (Mumbai), and Calcutta (Kolkata) were each granted a High Court by letters patent dated 26 June 1862. The letters patent were issued by Queen Victoria under the authority of the British parliament's Indian High Courts Act 1861. The three courts remain unique in modern India, having been established under British royal charter; this is in contrast with the country's other high courts, which have been directly established under the Indian Constitution. However, the Constitution of India recognises the status of the older courts.
