A federal judge has imposed sanctions on lawyers for GMAC, the bank that acts as the financial-services arm of General Motors that is now called Ally Financial, as requested by a pair of now-defunct car dealerships that had won a $4 million jury verdict in 2009 against the bank.

GMAC had put the two Kutztown, Pa., dealerships out of business when it seized them after claiming that they had failed to immediately turn over funds for 11 vehicles, lawyers representing the dealerships owned by Donald Mente had told the court at trial. The jury found that the dealerships were not “out of trust” under the terms of their contract with the bank.
