The supreme court, however, seems to think that it is somehow above checks and balances, and that any talk that they might have made a bad decision is somehow threatening the structure of the republic. BS. If they make up the law, congress can impeach them.
I'm wondering if we can't just get a 2-for-1 deal and send Breyer packing with O'Connor...
Judicial Independence has become code for, or a euphemism for Judicial Supremacy.
And you're right that this is an arrogant attitude held by Breyer. He's basically saying that the Courts' reckless and outrageous usurpation of power from the people and the states must be accepted w/o question or we are guilty of questioning the independence of the Courts. Who are we to dare question the invention out of thin air new rights to abortion and gay marriage? Who are we to dare disagree that the First Amendment stricture against Congress establishing a national religion also forbids the placing of nativity scenes on public grounds? Who are we to insist on deciding for ourselves those issues that the Framers of the Constitution clearly didn't see fit to elevate above the normal democratic process? Who are we to insist on self governance?
This is a very convenient attitude for people like Breyer, who shares part of the blame for turning the Sup Court into a political body, and for those who turn to the Courts to have imposed what they can't implement through the proper channels.
You forgot one very important check on the Supreme Court. According to Article 3, Section 2, Clause 2: "In all Cases affecting Ambassadors, other public Ministers and Consuls, and those in which a State shall be Party, the supreme Court shall have original Jurisdiction. In all the other Cases before mentioned, the supreme Court shall have appellate Jurisdiction, both as to Law and Fact, with such Exceptions, and under such Regulations as the Congress shall make." Therefore, Congress can remove entire classes of cases from the appellate jurisdiction of the Supreme Court.
