(CBS News) -- President Obama expressed confidence Monday the Supreme Court will not overturn his signature health care law when it issues a ruling later this year on the constitutionality of the landmark legislation, arguing it would be "unprecedented" for the court to make such a dramatic power play over Congress.
"I am confident that this will be upheld because it should be upheld," Mr. Obama told reporters at the White House when asked about the case at press availability after meeting with Canadian Prime Minister Stephen Harper and Mexican President Felipe Calderon.
Mr. Obama said a decision by the nation's top court to throw out the law would be unprecedented and precisely the kind of action that many conservatives for years have criticized as overreaching "judicial activism."
"Ultimately I am 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," Mr. Obama said in the Rose Garden appearance.
The president characterized the debate over the law as a "political" one, and said most constitutional law scholars believe the law should not be thrown out.
"That is not just my opinion, that is the opinion of a whole lot of constitutional law professors and academics and judges and lawyers who have examined this law even if they are not particularly sympathetic to this particular piece of legislation or my presidency," said Mr. Obama, himself a former constitutional law professor at the University of Chicago.
"I would just remind conservative commentators that for years what we have heard is the biggest problem on the bench was judicial activism or a lack of judicial restraint. That an unelected group of people would somehow overturn a duly constituted and passed law. Well, this is a good example and I am pretty confident that this court will recognize that and not take that step," he said.
On the most controversial aspect of the law, a requirement that everyone purchase health insurance or pay a penalty, Mr. Obama said there is more than just a legal argument to be made.
"I think it's important, I think the American people understand, and I think the justices should understand, that in the absence of an individual mandate, you cannot have a mechanism to ensure that people with pre-existing conditions can actually get healthcare," the president said.
"So, there is not only an economic element to this and a legal element to this, but there is a human element to this. And I hope that is not forgotten in this political debate," he added.
