John G. Roberts Jr. showed up for jury duty in Rockville like other civic-minded citizens and was being considered for a civil trial in a case involving a car crash. He answered two questions in open court about relatives — noting that his sister in Indiana is a nurse, and his brother-in-law was with Indiana State Police — but none about his own line of work, which would be listed on a questionnaire. He then talked with attorneys and the judge privately at the bench. Roberts was not selected, and left court without comment.The Washington Post article from which the above quote is taken goes on to note that Justice Kagen was also recently called to duty. She too was not selected to serve, though.
The National Constitution Center has more on why the Chief Justice was eligible to sit on a jury.
