Spyker has filed a 3 billion-dlr complaint against General Motors, claiming the US carmaker took "unlawful actions" that contributed to the bankruptcy of Sweden's Saab Automobile.

Spyker, a Dutch maker of luxury sports cars, bought Saab from GM in early 2010 for 76 million dlrs. But it failed to turn around the ailing Swedish carmaker. Saab filed for bankruptcy in late 2011 after attempts to find financial backers in China failed.

In the lawsuit, filed early Monday in the US District Court of the Eastern District of Michigan, Spyker alleges that  GM took action to avoid Saab falling into Chinese hands and become a competitor in that important market.

"GM's actions had the direct and intended objective of driving Saab Automobile into bankruptcy," Spyker said in a press release.

Spyker said that, without GM's interference, a tie-up between Saab, Spyker and China's Youngman would have allowed the Swedish carmaker to restructure and remain a solvent, going concern.

Victor Muller, Spyker's CEO and the main architect of the company's unsuccessful plan to restore Saab to profitability, expressed a strong commitment to the lawsuit. "Ever since we were forced to file for Saab Automobile's bankruptcy in December of last year, we have worked relentlessly on the preparation for this lawsuit," he said. The suit "seeks to compensate Spyker and Saab for the massive damages we have incurred as a result of GM's unlawful actions," he added.

Separately, bankruptcy administrators are continuing efforts to salvage the Saab brand with the help of an Asian-European consortium. An investment group said in June it had reached agreement with the administrators to continue saab as an electric-vehicle brand.
