General Motors Co. has asked a federal judge to reconsider the tossing of a lawsuit it filed last fall against Fiat Chrysler Automobiles NV, the car company's latest attempt at reviving an unusual legal battle between two of Detroit's biggest rivals.

In a new motion filed Monday in Detroit, GM said it had uncovered new evidence to further support its earlier claims that Fiat Chrysler was trying to weaken its larger competitor by bribing top officials with the United Auto Workers union.

Federal Judge Paul Borman last month dismissed GM's civil racketeering lawsuit, ruling the Detroit auto maker had failed to show it would have been a primary victim of any misconduct allegedly perpetrated by Fiat Chrysler executives.

GM's new motion not only claims it has new evidence to prove it was the victim of direct harm, but also for the first time names former UAW President Dennis Williams as a defendant.
