Recently, several Justices have opined on the legitimacy of the Supreme Court.
The Chief urged people not to criticize the legitimacy of the Court, simply because they disagree with an opinion.
"You don't want the political branches telling you what the law is. And you don't want public opinion to be the guide of what the appropriate decision is," said Roberts, who added, to laughter, "Yes, all of our opinions are open to criticism. In fact, our members do a great job of criticizing some opinions from time to time. But simply because people disagree with an opinion is not a basis for criticizing the legitimacy of the court."
