It’s also an incredibly dangerous thing for a justice to say because it just begs for a constitutional test. The court is probably best known for the ability to decide whether a law is constitutional, or judicial review, which is not spelled out in the constitution. So let’s say congress passes a law concerning ethics on the court and the court says “that’s not constitutional” and congress just goes “neither is judicial review.” Pure chaos. The courts power mostly is like that episode of The Office where Pam says she’s the office manager and everyone just goes along with it. The court says it has judicial review authority, and everyone just went “ok.”
