Robert Case, the former associate general counsel of the RAND Corp., is returning to the nonprofit policy think tank, this time as its top attorney.

Case, who served as RAND's associate GC from 2013 to 2015, returned on Monday as vice president, general counsel and corporate secretary.

Most recently, he was senior vice president and GC at ASRC Industrial Services, a diversified environmental, industrial and commercial services provider.

Case could not immediately be reached for comment. He succeeds Debra Schroeder, who had served as RAND's legal boss since late 2010. It was not immediately clear what Schroeder's next move is.

Prior to joining Santa Monica, California-based RAND for the first time, Case was deputy counsel at Pratt & Whitney Rocketdyne, a federal contractor and subsidiary of United Technologies, where he advised company leadership and program offices on aerospace, defense and energy systems matters, according to a statement announcing his hire.

A graduate of the UC Hastings College of the Law, Case previously served as an associate at Bremer Whyte Brown & O'Meara and later Tucker Ellis & West, both in Los Angeles, according to his LinkedIn profile.

Case specializes in government contracts and grants, commercial contracts, intellectual property rights and licensing, regulatory compliance, employment law and litigation, according to the RAND statement.
