Yes, the judge totally ignored Congressional intent. That is making the Judicial Branch superior to the Legislative and Executive.
The judge should have ordered the feeding tube restored, while a thorough new (de novo?) review of the case took place. This was not done. Can a federal judge be impeached by congress for disregard of the other two branches? This would send a good message to federal judges, that they are not the end of a matter, they have to take orders also. Those orders are not just the law (as they interpret it either).
He did not recuse himself because he is a conspirator and murderer.
Want to bet there are other victims?
I don't think Judges can be impeached under present system. Supreme and other Federal Courts Judges appointed for life by President, subject to Senate approval.
I actually had a post on my blog why not to have a possibility to impeach judges in light of how certain judges keep on abusing and outstepping their constitutionally defined power and hand one absurd verdict after another ("gay marriage" as a Constitutional Right, 10 commandement and other Jewish and Christian symbols removals from public places, Tossing out death Penalty case because one of the Jurors brought Bible, Terri Schiavo, etc.). Other possible solutions is to have Judicial term Limits for Federal Judges instead of life-time appointments.
This is very delicate issue, but something definitely must be done to institute more checks and balances in judiciary system.
