At times it also included the British military Commander-in-Chief of India (although this post was usually held concurrently by the Governor General).
It also added provision that Governor General was to be assisted by an executive council of four members and was given a casting vote but no veto.
Other members of the council included Lt. General John Clavering, George Monson, Richard Barwell and Philip Francis.
Philip Francis along with Monson and Clavering reached Calcutta in October 1774, and a conflict with Warren Hastings started almost immediately.
This attempt to impeach Hastings was unsuccessful and Nanda Kumar was hanged in 1775 after being found guilty of forgery by Supreme Court of Bengal in Calcutta.
[5] The trial was held under childhood friend of Hastings Sir Elijah Impey - India's first Chief Justice.
Clavering died a year later and Francis was left powerless, but he remained in India and strove to undermine Hastings' governance.
The act restricted the Supreme Court's jurisdiction to either those who lived in Calcutta, or to any British Subject in Bengal, Bihar and Odisha.
