BTW, while all but 3 of the 111 SCOTUS Justices have practiced law at some point before being appointed to the court, they have all had some training in the law, but the last one to be appointed without a formal law degree was appointed in 1938.

Forty of the justices, though, had no previous experience as judges. They include Chief Justices John Marshall, William Rehnquist, and Earl Warren.
