Revenue Reforms: Although the Company had got the diwani of Bengal, Bihar and Orissa in 1765, the work of collection of land revenue had been left in the hands of amils. Warren Hastings decided that the Company must directly collect the revenue. Consequently, he appointed collectors for revenue collection and administration, who were to be helped by native officers. Settlement was made for five years with the highest bidders. To supervise the whole organization, a Board of Revenue was established at Calcutta. This revenue system was found to be defective and consequently in 1777 the old system of bidding for a year was resorted to. He made the account of revenue simple and intelligible and made many provisions for the protections of ryots.
Economic Reforms: Warren Hastings prohibited the used of dastaks by the servants of the Company and thereby added to the revenues of the Company. He abolished a large number of custom houses or chowkies as they were hampering the growth of trade in the country. He reduced the duties on all goods except salt, betel nut and tobacco.
He reduced the allowance of the Nawab of Bengal from 26lakhs of rupees to 16 lakhs of rupees. He also took over district of Kora and Allahabad from the Mughal emperor and sold them to the Nawab Wazir of Oudh for rupees 50 lakhs. He also obtained a large sum of money from the Nawab of Oudh for helping him against the Rohilas.
Judicial Reforms: Warren Hastings carried out a large numbers of reforms in the judicial sphere. In 1772, he established Diwani Adalat ( Civil Court
) and a Faujdari Adalat (Criminal Court) in each districts. The Diwani Adalat was presided over by the English collector and Faujdari Adalat was presided over by Indian officersQazis and Muftis. Two courts of appeal were established at Calcutta. They are the Sadar Diwani Adalat (the Supreme of Civil Court) and the Sadar Nizamat Adalat (the Supreme Criminal Court) which heard appeals from the Diwani Adalat and Faujdari Adalatrespectively. He also compiled a simple code about the personal laws of Hindus and Muslims.
