The Ṣadr Dīwānī ʿAdālat (Urdu: صدر دیوانی عدالت ) (English: Sudder Dewanny Adawlut) was the Supreme Court of Revenue in British India established at Calcutta by Warren Hastings in 1772. It was reformed in 1780 and again in 1793 by the British Parliament. The court's judges were the Governor General and Council Members of the East India Company, assisted by native judges and officers of revenue.
The term is in the Urdu language:
The court was established to allow Hindu Indians to be governed by Hindu law in matters of property, and not as before by Muslim law, although they were still subject to Muslim criminal law.
In each of the districts of British India, subordinate courts of revenue with definitive jurisdiction of up to 500 rupees, were established in which the judges were the relevant District Collector and his deputy and register, assisted by native officers. For cases exceeding 500 rupees, appeals were allowed to the Sudder Dewanny Adawlut.
The court was abolished after the Indian Rebellion of 1857.
