What penalties, if any, are applicable to those who judges who reach decisions that annoy the government?
I'm doing some reading on the system over here and trying to reach some understanding, I'd like to grasp how it works 'over there' too. Some opinions would be very welcome too.
Oh, there's a lot that can be done to reign in the Judiciary.
The Constitution says little, save that there will be a supreme court with certain jurisdiction, and that the legislature can flesh out the court system.
Judges can be impeached. There isn't a hard and fast rule for what constitutes an impeachable offense. In Nixon v. US (1993) an impeached federal judge sued to have his impeachment overturned on technicalities. One of the issues that came up was what it takes for an impeachment....basically, it's what the Senate thinks deserves impeachment.
Congress can cut funding to the courts. They can't diminish salaries for sitting judges, but there's no duty to fund the construction of new court buildings; one of the classic examples a JD I used to study under brought up is 'they don't have to pay to air condition the new court.'
Nor is there any duty to appropriate money for the upkeep of the Supreme Court building. Congress could legally stop funding that and tell the justices to meet in the broom closet in the basement of the Capitol building. There's a lot to be said for holding the purse strings of the nation.
When the Court rules that certain governmental actions are illegal, the other branches can just flat out ignore it. Andrew Jackson said something to the effect of "the Court made their decision, now let's see them enforce it." The one big example I'm familliar with was INS v. Chadha, in which the Court declared one house vetoes of executive agency decisions illegal. The Senate and Congress still do those constantly.
Congress has set sentencing guidelines. (Mistretta v. US) Basically, in criminal cases, a judge is now supposed to look at a chart which will give a sentence range, say, 3-5 years. There are certain extenuating circumstances, but one of the big things the DoJ is doing now is to keep tabs on all sentences handed down. As a segue, [edit]Congressman Feeney*** said that anyone giving lesser sentences than those proscribed was grounds for for impeachment.
Congress can suspend the writ of habeas corpus to prevent the courts from hearing certain cases. This is the nuclear bomb of legal retaliations, though.
Someone mentioned fillibustering appointments. There are other fun things that can be done to muck with court composition. During Senate recess, the President can appoint without any confirmation. However, these appointees must later be confirmed or they must step down. Also, as the number of Supreme Court justices is defined by statute, the house and senate can pass a bill stating that there will be "x" justices, and possibly work with the president to pack the court with justices who will be favorable to the current political climate.
If they had a real wild hair, Congress and Senate could simply abolish a federal court which gave decisions they hated.
Since the Courts rule on principles of law, and the House and Senate can pass or rescind laws, they can change the legal framework upon which a decision was based. If it's a constitutional issue, the Constitution can be amended.
So, getting back to the point: legal penalties, as such, are impeachment. There is a great deal which can be done to influence decisions, or to harass for decisions already made.
***Edit. Remembered the name. Feeney and Delay have formed a caucus on judicial accountability. You may wish to look into that a bit.
