The bankruptcy judge overseeing the Chrysler case had given approval for the company's most valuable assets, such as plants, dealerships and contracts, to become part of a new company in which Fiat would hold a significant stake.

Supreme Court Justice Ruth Bader Ginsburg, in an order issued late Monday, granted a request for a delay of that approval sought by Indiana state pension funds, which had argued that they and other lenders deserved better treatment by the bankruptcy court.

No reason for the delay was given in the order, and there were no details about how quickly the issue could be resolved by the nation's highest court.
