Roberts is scum because he didn't vote your way?
I would not call Roberts 'Scum', but he did throw his reputation as a non-partisan Justice away in his ruling on Obamacare.
Justice Kennedy said it bluntly, that it was NOT the duty, responsibility, or role of the USSC to CHANGE the Government's Judicial Argument but that is what Roberts did.
The WH lawyer argued the punitive tax' being imposed on people who refused to buy the ACA was a 'FINE' - a negative incentive for NOT buying into the program. Kennedy pointed out that this should have been a SHORT case because such a 'FINE' was UN-Constitutional.
What SHOULD HAVE happened at this point, after the FINE was ruled Un-Constitutional, was the WH lawyers file for an appeal, change their argument, and present that argument at the next court case....if they had done so (which I can't imagine they would not have).
INSTEAD, as Kennedy pointed out, it was Chief Justice Roberts who CHANGED THE GOVERNMENT'S ARGUMENT FOR THEM, declaring WHAT THE GOVERNMENT MEANT TO SAY WAS that the punitive fine was actually a 'Tax'. As Kennedy pointed out, Roberts stepped way out of his lane to change the argument of a lawyer appearing before him for the benefit of that lawyer, an act which DID change the outcome of the court's decision.
Kennedy THEN pointed out the trial should have immediately been STOPPED, after the argument was changed from it being a 'fine' to a 'tax', because ACCORDING TO THE LAW a case regarding a Tax CAN NOT be heard until AFTER the 1st time the tax was imposed, which it had not been. STILL Roberts allowed the trial to continue...
Although it is most probably that the Obama administration would have eventually won, Roberts single-handedly went out of his way to prevent the WH's case from being dropped, as it initially should have been. Roberts single-handedly changed the govt's argument, allowed it to continue - even though it wasn't supposed to, and basically saved the ACA...or at least saved months to a year of the case going forward.
After Obama had insulted and verbally attacked the USSC (Remember how the USSC had refused to stand when he walked in to give one of his State of the union addresses after Obama had insulted / impugned the court earlier that week?), Roberts did go well above and beyond to ensure Obama's ACA was found Constitutional.
(There was a 'conspiracy theory at the time that the effort to adopt a foreign child by the Roberts was threatened if he did not do what he could to see the ACA passed this USSC test. While I don't believe it, the actions of Roberts did seem out of the norm for him, enough for Justice Kennedy to rail a bit about it in his arguments.)
