At his confirmation hearing for Chief Justice of the U.S. Supreme Court, John Roberts famously said:
Judges are like umpires. Umpires don't make the rules. They apply them. The role of an umpire and a judge is critical. They make sure everybody plays by the rules. But it is a limited role. Nobody ever went to a ballgame to see the umpire.
Infamously, Chief Justice Roberts failed to follow his own advice when he upheld the Obamacare individual mandate in NFIB v. Sebelius.
Do as Chief Justice Roberts says, not as he does.
