Dutch sports car maker Spyker said it will appeal a U.S. judge’s decision to dismiss its $3 billion lawsuit accusing General Motors Co. of trying to bankrupt Swedish automaker Saab.

Spyker said on Wednesday that it would appeal the decision following a “careful review” of the court’s opinion. No further details were disclosed and Spyker CEO Victor Muller was not immediately available to comment.

U.S. District Court Judge Gershwin Drain said on June 10, in tossing the lawsuit, that GM had a contractual right to approve or disapprove the proposed sale of Saab to China’s Zhejiang Youngman Lotus Automobile Co.

Saab stopped production in May 2011 when it could no longer pay suppliers and employees. It went bust in December 2011, less than two years after GM sold it to Spyker.

Spyker sued GM in August 2012, seeking damages and accusing GM of trying to scuttle the deal with Zhejiang and eliminate a potential rival in the growing Chinese market.
