Noteworthy Representations

Represented the National Credit Union Administration as liquidating agent in a series of lawsuits against major financial institutions regarding the sale of residential mortgage-backed securities.   The suits were filed in three federal district courts and generated multiple appeals to three Courts of Appeals. Dan was involved in all aspects of the litigation, including drafting the complaints, briefing dispositive motions and appeals, taking and defending fact and expert depositions, and managing discovery. Each suit was resolved prior to trial, with defendants in three suits offering judgment for the full damage demand plus attorneys’ fees. More than $5.1 billion has been recovered. 

Successfully briefed and argued against an appeal brought by two groups of objectors to a class action settlement agreement. The settlement agreement concerned overpayments for motor fuel and resolved more than eight years of multi-district litigation. See In re Motor Fuel Temperature Sales Practices Litig., 872 F.3d 1094 (10th Cir. 2017).
