Hell Roberts was so determined to rule unanimously in favor of the ACA that he rewrote Obama's argument himself.
Not only did he rewrite Obama's argument, but then he agreed with what he, himself, wrote and not with what Obama was presenting. He rewrote Obama's argument to make it what he, Roberts, thought that Obama should have been arguing, not what Obama was actually arguing. The single most bizarre ruling that I know of in the history of the Supreme Courts.
Can you imagine presenting a case before a judge, and the judge rejects your case. But, he then rewrites his own version of your case, and then rules in your favor based on the case he wrote for you in that he agrees with himself. Bizarre is putting it mildly.
