Former George W. Bush Solicitor General Paul Clement of Kirkland & Ellis will defend the single-director structure of the Consumer Financial Protection Bureau at the U.S. Supreme Court this term, arguing in the closely watched case at the invitation of the justices after the U.S. Justice Department abandoned defending the agency.

The high court issued an order Wednesday announcing Clement’s “invitation” to brief and argue the case. The justices agreed last week to hear Seila Law v. CFPB, a major test of the president’s power to fire the heads of independent agencies. The consumer bureau director, who serves a five-year term, can only be fired for cause, not at-will. The court has not set an argument date.
