Just when boutique international law firm ShawnCoulson thought it was out, a former client has pulled it back in.

In August 2009, ShawnCoulson settled a $2.2 million fee dispute in U.S. District Court for the District of Columbia with former client PowerTrain Inc. Late last year, the Mississippi-based engine parts importer moved to reopen the case, seeking sanctions for an allegedly false affidavit filed in the case.
