Dutch car company Spyker is suing General Motors for three billion dollars over the bankruptcy of GM's former brand, Saab.
Spyker says GM illegally interfered with a sale of part of Saab, and claims it was that interference which caused Saab's bankruptcy.
GM sold Saab to Spyker in 2010, with a stipulation that Spyker would have to obtain GM's permission to sell Saab to anyone else.
Spyker almost immediately ran into financial problems trying to keep Saab afloat.
