Gregory Garre, who was deputy solicitor general and then briefly solicitor general at the end of the Bush administration, has begun work as chair of Latham & Watkins‘ Supreme Court and appellate practice group in the firm’s Washington, D.C., office. He will take over that role from Maureen Mahoney, who has headed Latham’s 70-lawyer appellate practice for two decades. As with any former SG, this is a significant catch for the firm.

Garre says Mahoney has decided to “step back her practice.” Mahoney could not be reached for comment, but in a statement released by the firm she said, “Greg is a superb lawyer and friend. We are delighted that he has agreed to join us and assume the leadership of our appellate group.”
