Not at all. Roberts said the role of the Court was to make sure legislation comported with the Constitution. Thus he substituted taxation for commerce clause.
This will rank him with Marshall and Warren if he keeps it up. Wow!
If you just look at the politics of the judgement, it looks like an objective judge who really interprets the constgitutionbut in reality, Roberts ruled that the individualmadate AS WRITTEN in the law was unconstitutional and then ruled it could be constitutional as argued by the president's attorneys. That in essence is a legislative court maneuver. The law has to be interpreted as written, not argued.
The attorneys could say anything, and essentially did. Listen to Obama now. "It is NOT a tax!"
