"Only the LG (Najeeb Jung) can say what will be done. Only he can take any decision," Rajnath Singh said when questioned about the prevailing political situation in Delhi.
Asked what would be the home ministry's recommendation to the president on the issue, the minister said: "The president has not sought our advice."
He, however, refused to comment on allegations of MLA poaching against the Bharatiya Janata Party (BJP).
The Aam Aadmi Party Monday released a video which showed Delhi BJP vice president Sher Singh Dagar allegedly offering a plum post and money to AAP legislator Dinesh Mohaniya in a bid to help the BJP to take power in Delhi.
Meanwhile, reports suggested Jung is likely to invite the BJP to form the government in the national capital.
Delhi has been under President's rule since AAP chief Arvind Kejriwal resigned as chief minister Feb 14 after 49 days in office.
The BJP won 31 seats in the 70-member house but now has 28 legislators after three were elected to the Lok Sabha in the general elections held in April-May.
