John Roberts, Robert M. Bell

In this May 18, 2006, file photo, Robert M. Bell, left, Chief Judge of the Maryland Court of Appeals, presents U.S. Supreme Court Chief Justice John Roberts with a Maryland flag bowtie at the Maryland Judicial Conference in Cambridge, Md. Bell was 16 years old when he recruited classmates to join a sit-in at a downtown Baltimore restaurant. Twelve demonstrators, including Bell, were charged 50 years ago this month with trespassing in a civil rights case that eventually made it all the way to the U.S. Supreme Court. In the 50 years since Bell v Maryland, Bell, now retired, went on to become a lawyer and later a judge on Maryland’s highest court, where he sat on the bench with two men who had been prosecutors on his case.
