Jeffrey Wall is the latest lawyer to decamp the U.S. solicitor general’s office to lead or co-lead a major law firm’s appellate practice. But Wall traveled a slightly different path when he left last fall, signing on as special counsel at Sullivan & Cromwell, a Wall Street titan, rather than heading to a Washington or Chicago firm with deep experience at the high court.

Given the fickle attention New York firms have given to high court practice, Wall’s move may be something of a gamble. But two months into Wall’s job as co-head of the firm’s appellate litigation practice, a colleague says Wall has already established that his experience in the SG’s office—he argued 10 cases over five years—is of value to the firm.
