From another thread Anti-Federalist papers 78-82 - The Power of the Judiciary comes the following quote from the Federalist Papers, which is more likely right in its understanding of the Constitution than I:
The only clause in the constitution which provides for the removal of the judges from offices, is that which declares, that "the president, vice- president, and all civil officers of the United States, shall be removed from office, on impeachment for, and conviction of treason, bribery, or other high crimes and misdemeanors." By this paragraph, civil officers, in which the judges are included, are removable only for crimes. Treason and bribery are named, and the rest are included under the general terms of high crimes and misdemeanors. Errors in judgment, or want of capacity to discharge the duties of the office, can never be supposed to be included in these words, high crimes and misdemeanors. A man may mistake a case in giving judgment, or manifest that he is incompetent to the discharge of the duties of a judge, and yet give no evidence of corruption or want of integrity. To support the charge, it will be necessary to give in evidence some facts that will show, that the judges committed the error from wicked and corrupt motives.As this paper notes elsewhere: Men placed in this situation will generally soon feel themselves independent of heaven itself.
The remaining path, short of revolution, is to put forth good judges. We can only turn back this tide one bail at a time.
