"We will not give in to someone else's calendar of saying you must do it (forming Delhi government) without consulting the people," he told reporters in Bangalore.
His assertion came after Union Home Minister Sushilkumar Shinde said the central government would give some more days to AAP for government formation in Delhi. "We will give some more days (to AAP) for government formation in Delhi. This is a democratic process," Shinde said.
Yadav said AAP would consult the citizens of Delhi no matter if any party or an individual gives a time-frame to form government.
On Wednesday, AAP had announced that it would distribute 25 lakh copies of a letter seeking people's views on the issue of government formation and that replies will be accepted till December 22.
"If the constitutional calendar says you cannot form the government, that's all right, we will not form it," he said.
AAP had sought time from Delhi Lt Governor Najeeb Jung to take a decision whether to form the government after Congress, with eight MLAs, offered outside support to the Arvind Kejriwal-led party.
In a House of 70, BJP (31) and its ally Akali Dal (1) together have 32 seats, four short of a majority, while AAP has 28 seats.
Jung has already recommended that Delhi be put under President's rule with the new assembly in suspended animation, among other options.
The imposition of central rule was one of the options listed by Jung in his report submitted to the President after his consultations with BJP, the single largest party, followed by AAP.
