A judge has temporarily stopped the Philadelphia school district from imposing health care costs on teachers.

Common Pleas Court Judge Nina Wright Padilla issued a preliminary injunction on Monday.

The teachers union sought the ruling after the School Reform Commission canceled its contract Oct. 6.

Commissioners say the cash-strapped district can't afford the agreement, which gives teachers free health benefits. They want to impose new terms that would cost teachers up to $140 per month.

The union contends the parties must go to arbitration before any changes can be made. The two sides have been negotiating for more than a year.

Union president Jerry Jordan said Monday that he's pleased with judge's decision.

District spokesman Fernando Gallard says the district will appeal to Commonwealth Court.
