When Marc Raspanti left the Philadelphia District Attorney's Office in the late 1980s to strike out on his own, he wasn't sure where to focus his practice.
He started out with a fairly standard white-collar defense practice with a private firm, drawing on his experience with the district attorney. But he soon set up his own firm and moved into whistle-blower lawsuits - a fateful decision, it turns out.
Whistle-blower lawsuits have boomed in recent years, and Raspanti's practice, along with those of the small clutch of other lawyers who handle these cases nationally, has grown accordingly.
Since Congress bolstered the federal False Claims Act in 1986 by expanding the circumstances under which contractors can be sued for cheating the government, financial penalties assessed against crooked companies have reached $27 billion, according to the latest Department of Justice compilation.
