The Senate is poised on Tuesday to confirm Patricia Millett to a key federal appeals court in Washington, making her the first nominee approved under a new streamlined procedure that could deliver a pre-holiday rush of judges to the bench.

Millett, a co-leader of Akin Gump Strauss Hauer & Feld’s appellate and U.S. Supreme Court practice, would become the sixth woman ever to sit on the influential U.S. Court of Appeals for the D.C. Circuit. The court’s decisions in the regulatory arena—from securities law to the environment—have national sweep.
