I am sad to report that Robert J. (Bobby) Lipkin has passed away. From the Widener website:
Robert 'Bobby’ J. Lipkin, a Distinguished Professor of Constitutional Law on Widener Law’s Delaware Campus, passed away on Thursday, February 18th. The Widener Law community’s thoughts and prayers are with Professor Lipkin’s loved ones. We are shocked and saddened by his passing and share their grief. Bobby Lipkin was an exceptional individual, a good friend, and a respected professor. His passing is a substantial loss for the entire law school community. He will be missed by all of us privileged to have known and worked with him.
Bobby was a frequent and stimulating contributor to many online discussions.
