Prasad is also the fifth governor to have been sworn in in as many years since July 2013.
The Chief Justice of Meghalaya High Court. Justice Dinesh Maheshwari administered the oath of office and secrecy to Prasad in the presence of Chief Minister Mukul Sangma, his cabinet colleagues, MLAs and senior officials of the government.
Prasad relieved B Purohit from his additional charge as governor of Meghalaya, a temporary appointment made after V Shanmuganathan resigned earlier this year on charges of compromising with the dignity of the gubernatorial office.
