Moving swiftly, a two-judge panel of the 2nd U.S. Circuit Court of Appeals on Thursday heard an appeal of an order issued on the eve of trial disqualifying Debevoise & Plimpton as counsel for MetLife in an $8 billion class action.

Eastern District of New York Judge Thomas C. Platt on Tuesday issued the order disqualifying Debevoise, which represented MetLife during its conversion in 2000 from a mutual company to a publicly traded stock company, and has handled litigation arising from the conversion ever since.
