Absolute criminal immunity isn't a thing. It has never been a thing. Trump made it up.
If the Supreme Court rules for him, they give up all their own power because all the President needs is enough members of Congress to refuse to impeach or remove him, and he can literally do anything.
Any crime. Anything.
If the Supreme Court does that, it's literally all over.
Incidentally, they also lose their own power. If they create a dictator they are dispensable.
