Members of the United Auto Workers union have overwhelmingly approved picking their leaders by direct ballot elections, rejecting a system that many blamed for a bribery and embezzlement scandal in the union’s top ranks.

The “one member, one vote” measure got about 64% of 140,586 valid ballots that were received by Monday’s mail-in deadline.

Only about 36% favored the current system of leadership picked by delegates to a convention, according to results released Thursday.

The results are not official until approved by the Labor Department and a federal judge.

A court-appointed monitor will develop rules and oversee the election of the union’s 13-member International Executive Board, which includes the president, three vice presidents, secretary-treasurer and regional directors. All current board members including President Ray Curry are expected to run.

The monitor, Neil Barofsky, said Thursday in a statement that the election is likely to take place in the summer or fall of next year.
