"Extraordinary" and "Unprecedented" ?

Today as the Supreme Court continues to hear arguments on the constitutionality of ObamaCare, the President made this remark:

Ultimately, I'm confident that the Supreme Court will not take what would be an unprecedented, extraordinary step of overturning a law that was passed by a strong majority of a democratically elected Congress

Were the Court to rule the law is indeed unconstitutional it would hardly constitute an unprecedented or extraordinary act.

See the following government documents for lists of Acts of Congress  (last updated 2002) struck down as unconstitutional by the Supreme Court (158 are listed): ACTS OF CONGRESS HELD UNCONSTITUTIONAL IN WHOLE OR IN PART BY THE SUPREME COURT
