The Supreme Court is refusing to disturb a ruling from New Jersey's top court that sided with Gov. Chris Christie in a legal fight with public worker unions over pension funds.

The justices did not comment Monday in rejecting the unions' appeal. The high court order came less than three weeks after Christie ended his run for the Republican presidential nomination.

New Jersey's Supreme Court ruled last year that the state is obligated to pay individual retirees their pensions. But it overturned a lower court ruling that would have forced the state to come up with billions to pay promised pension benefits.
