Congress has the authority to take away the court’s appellate authority in the vast majority of cases

Yeah, in theory, but that’ll happen roughly never. Congress is far too focused on decorum, and tradition, and making insider stock trades to enrich themselves to pull their collective heads out of their own asses to pass even basic, simple, required and popular laws never mind spending time to fix other branches of the government.

I don’t want to veer into the failed state crackpottiness or anything, but even an actual insurrection invading the capitol didn’t get them to do anything so I’m at a substantial loss as to what could possibly motivate congress to you know, legislate.
