Michael Saunders, a former partner at Unisys federal systems division, says the company terminated him for not cooperating in a $13 million overbilling scheme related to a task order on the Army's Joint Automated Identification Technology program. Saunders filed suit under the Fair Claims Act, including one claim for the fraudulent overbilling and one alleging retaliation. Last October, Unisys asked the court to dismiss the complaint, arguing the company had self-disclosed the billing problems before Saunders was hired and that he was simply recycling the charges for personal financial gain.
