Greenberg Traurig and Hunton & Williams are defendants in a federal suit filed Nov. 15 by investors in R. Allen Stanford’s failed companies and a court-appointed receiver.

The complaint in Ralph S. Janvey, et al. v. Greenberg Traurig, et al. alleges that the firms helped Stanford shield his “offshore Ponzi bank” from regulatory scrutiny and deceived Stanford customers into believing his investment business was legitimate.
