Case Facts & Court Holding

Key Facts & Case Background

The Lancelot Funds, managed by Gregory Bell, invested in Thomas Petters’ ventures, which were later revealed as a Ponzi scheme. In 2005, the Funds hired Winston & Strawn LLP (W&S) to revise their offering circular. Bell allegedly informed W&S that Petters refused inventory verification and did not use lockboxes, contrary to representations. The revised 2006 circular, prepared by W&S, continued these misrepresentations. Bell eventually pleaded guilty to fraud, admitting knowledge of the scheme from early 2008, but claimed ignorance during W&S’s engagement. The Funds’ bankruptcy trustee sued W&S for malpractice, arguing the firm should have alerted the Funds’ directors to Bell’s and Petters’s conduct and ensured the 2006 circular was accurate. The district court dismissed the complaint, invoking in pari delicto, reasoning Bell’s (and thus the Funds’) knowledge was at least equal to W&S’s. The trustee appealed, standing in the shoes of the Funds.

Court Holding & Legal Precedent
