But the appeal by Mr. Erdogan’s party, Justice and Development, may forestall that. After submitting the application for a do over, Ali Ihsan Yavuz, the party’s deputy leader, told reporters outside the headquarters of the High Election Council in the capital, Ankara, that 85 percent of the mistakes detected in the voting were against his party. He added that the irregularities included 16,000 votes for Justice and Development having been erroneously recorded for other parties.

“There is complete organized irregularity and complete election corruption,” he said. “It shows us the will of the nation was snatched away.”

Officials from Mr. Erdogan’s party, Justice and Development, have been saying for several days that as a final resort they would lodge an “extraordinary application” for a rerun of the race because of what they called numerous and grave irregularities. A decision from the election council could come within days, and a new vote would be held on June 2 if the governing party’s application were accepted, officials have said.

Eleven judges sit on the board of the High Election Council, elected by judges of the Supreme Court and the State Council. The judiciary in Turkey has come under increasing government control in recent years as hundreds of judges, prosecutors and lawyers have been imprisoned or purged from their jobs since a failed coup.
