Not likely but, a Supreme Court Justice may be impeached by the House of Representatives and removed from office if convicted in a Senate trial, but only for the same types of offenses that would trigger impeachment proceedings for any other government official under Articles I and II of the Constitution.
Article III, Section 1 states that judges of Article III courts shall hold their offices "during good behavior." "The phrase "good behavior" has been interpreted by the courts to equate to the same level of seriousness 'high crimes and misdemeanors" encompasses.
In addition, any federal judge may prosecuted in the criminal courts for criminal activity. If found guilty of a crime in a federal district court, the justice would face the same type of sentencing any other criminal defendant would. The district court could not remove him/her from the Bench. However, any justice found guilty in the criminal courts of any felony would certainly be impeached and, if found guilty, removed from office.
>This is one that can’t be undone
In addition to the legal method of impeachment to undoing this there is the illegal option of assassination {and don’t hesitate to believe that the statists wouldn’t “false flag” as ‘right-wing extremists’ to assassinate her to gain political power}.
This is perhaps the “big thing” that I can see happening; once things “break down” enough that CWII is starting the ‘statists’ could sacrifice a number of their own to placate the majority and then keep things right at that level for a while {then they could claim “it’s always been this way” as a response to any concerns about freedoms/liberties} before resuming their course again.
