Cravath, Swaine & Moore rarely sees lawyers moving to and from its partnership ranks, but bankruptcy bigwig Richard Levin has now bucked that trend twice. Levin will relocate to Jenner & Block effective May 18, his new firm announced Monday.

Levin was lured to Cravath in 2007 from Skadden, Arps, Slate, Meagher & Flom in a move that surprised the legal community, given the former's propensity to promote from within. Cravath's addition of the bankruptcy and restructuring expert was hailed as a sign that the practice area had become one worthy of even the most elite Wall Street firms.

But at 64, Levin is now approaching Cravath's mandatory retirement age. And he says he's not ready to stop working. “Sixty-five is the new 50,” Levin says. “I'd be bored. I love what I do, [and] I want to keep doing it.”
