Kejriwal said he would respect and follow the "people's verdict", whether it was against or for the party.
He said there was a divided opinion over the issue and during the meeting of MLAs, a section was of the view that AAP should not shy away from forming the government as Congress was extending unconditional support.
According to some MLAs, the party could implement its agenda as there would be no interference by the Congress.
"BJP. But off late, a section of people started to say that we should form the government while another section was opposed to it, so we decided to go back to people to decide," he said.

AAP had yesterday decided to seek people's opinion through SMS, mails, and phone on whether it should form the government or not with the outside support from the Congress.
He said that among the many new things that AAP had brought into politics was the concept of participation of common man in formation of government.
Asked whether the party was outsourcing its decision by going for a referendum, the AAP leader said "it was not outsourcing of decision but what happens today is outsourcing and we want to bring an end to this system."
Kejriwal said he agrees that the party cannot go to people for every decision but "participation of people was important in critical and important decisions".
