The file has been forwarded to President Pranab Mukherjee, who is likely to review the case only after his return from the six-day historic visit to West Asian countries including Israel and Palestine, official sources said here.
The President had last month returned the file of the HRD Ministry, which recommended sacking of Dattagupta, and had asked it to seek legal opinion before any decision could be taken on the matter.
A committee, constituted by the HRD Ministry to go into the allegations levelled against Dattagupta, claimed to have found him guilty of administrative and financial wrongdoings.
The Ministry moved for Dattagupta's sacking as it was "unconvinced" by his reply to the show-cause notice issued to him in June.

Though the existing laws relating to central universities do not provide for sacking of a vice-chancellor, the President can invoke section 16 of the General Clauses Act, 1987, to remove him.
