This may be a tad over-stated here.
The Congress has complete authority over Judge Jackson. She may be impeached by the House and convicted and tossed off the bench by the Senate.
Also, she can be tried, found guilty and jailed for any common criminal offense like attempting to illegally influence the outcome of a trial. If it should be discovered that Judge Amy Berman-Jackson knowingly conspired with that Dem activist jury foreperson before or during Stone's trial, she will have to be arrested, jailed and await judgement on the merits.
Any federal judge like Amy may be prosecuted in the criminal courts for criminal activity. If found guilty of a crime in a US District Court, Judge Berman-Jackson would face the same type of sentencing any other criminal defendant would.
True...but it will never happen. In the history of the US...only 15 federal judges have been impeached. Only 8 convicted. And none of those convicted were for bias. So thus no one has authority over her.
