> they’re appointed by the government for life.
“In good behavior”, actually.
> There’s literally nothing the public can do (short of revolution) that impacts their jobs.
Political pressure on Congress to impeach a particular justice, or exercise its power to adjust the scope of the appellate jurisdiction of the Court, as well as taking direct extralegal action against specific judges are all acts “short of revolution”.
> Historically, no Supreme Court justice has ever been impeached by the House and convicted by the Senate. It’s been around 200 years (1805) since the last attempt was even made.
No, 1805 was the only successful impeachment of a Supreme Court justice, though no conviction occurred in the Senate. The last attempt (counting only those where there is some official action in the House directed explicitly directed at impeachment) was far more recent, 2019 against Justice Kavanaugh (H.Res. 560).
