This is exactly why we should not have lifetime appointments to the Supreme Court, and why our SCJ's should have more oversight and accountability, not for their decisions, but for their actions. This line pretty much sums it up:
"In fact, justices are exempt from the Code of Conduct that governs the actions of lower federal justices."
That's pretty much the problem in a nutshell. You have judges like Scalia and Thomas, very brazenly taking part in public functions that present them as being partisan on their decisions, yet there is no way to sanction them. They have been passing down decisions that have gutted our democratic process, they have disregarded common sense and non-political objectivity, and have instead become what the conservatives also decry as "rogue judges". By popular definition, a rogue judge is one whose decisions are driven by personal belief, personal gain, personal politics, and are purely subjective. All of these things are meant to be barred from our judicial process because it creates a conflict of interest. It is why a person who was once a member of the gun lobby should no preside over a case involving gun rights.
This cuts both ways, of course, but this kind of blatant partisanship is a slap in our nation's face. They are clearly making a statement that they've already had their minds made up. They are lining their pockets with the money from these groups who are fighting health care reform, and yet there is no way to counter this. We can't kick them out, we can't provide oversight for their actions, and we have no authority above them to stop this kind of thing. In short, they are free to be as un-judicial as they want. In the end, they will be making another party-line vote, as all parties have apparently made up their minds already. Why go through the farce of hearing the case at all? It's a mockery of our system, and we should not have to live with this.
