Facebook is expanding its legal team -- perhaps just in time -- and its newest hire comes from behind the bench. U.S. Magistrate Judge Paul Grewal will join the company in late June as its Deputy General Counsel, after serving in the North District of California since being appointed in December of 2010. The Recorder first reported the move, noting that Grewal pulled out of several cases involving Facebook in January. In his time on the bench he has ruled on cases involving the social network before, like this ruling on parents trying to access messages in their dead daughter's account, or another case over an outside developer's storage and use of customer data.
