LOS ANGELES (CNS) - Los Angeles City Controller Ron Galperin, who has  been fighting to audit two trusts controlled by the union representing  Department of Water and Power employees, said today he would not authorize $4  million in annual payments to the trusts this fiscal year.

For the past decade, the trusts have each received $2 million annually,  but Galpin said he could not ``in good conscience, authorize the payments at  this time.''

Employee union members of the Joint Training Institute and the Joint  Safety Institute, which handle safety and training programs for Department of  Water and Power workers, have refused to turn over financial documents on how  the money was spent.

'`As the city controller, I have a duty to protect the public's money  and to ensure that city funds are spent appropriately,'' he said.

Brian D'Arcy, the head of the International Brotherhood of Electrical  Workers Local 18, which represents DWP employees, did not immediately respond  to an email seeking comment. The union is fighting a Los Angeles Superior Court  judge's decision to order the union to open its books on the trusts. Galperin cited a city ordinance that gives him the authority to withhold  payments ``if there is a question as to whether it is improper.''
