Unprecedented?

Mr. Obama said that it would be unprecedented for the Supreme Court to rule any portion of Obamacare unconstitutional.  Where did he go to law school again? Does the president have access to the internet?

I did a quick search and found this information-- Answers.com

The US Supreme Court has declared a total of 1,315 laws (as of 2002, the most recent year for which statistics are available; the database may be updated in 2012) unconstitutional using the process of judicial review.

The first time the Court declared a federal law unconstitutional was in Chief Justice John Marshall's opinion for Marbury v. Madison, 5 US 137 (1803), in which he asserted Section 13 of the Judiciary Act of 1789 was unconstitutional because it extended to the Supreme Court an act of original jurisdiction not explicitly granted by the Constitution.
