"Imperial Courts"

I read this Quote in a Newsweek article: ""It shows that the imperial judiciary thinks that, in addition to abortion, affirmative action and religion, war should be within its grasp," says John Yoo" and I had to take a double take. This John Yoo, A Berkeley law professor said the courts are becomming to "Imperial"? This in regards to a decision that the Supremem court made regarding how our president has overreached his power in the use of Military Tribunals in the name of fighting terrorism. The irony is causing me to make a scene at work!
