arguments on president obama's hotly debated health care law. it's a historic and partisan battle with dramatic changes in this country's health care system and the reach of the federal government. the justices will consider four different legal issues. up first this morning, the basic question, is it too soon for the courts to even take up this law? susan mcginnis in washington. good morning to you. >> reporter: good morning. the central issue this week the supreme court will hear is whether it's constitutional to require americans to buy health insurance. but today the court is going to hear arguments about whether it's legal for them to even decide on this law before key elements of it go into effect. people have been lining up outside the supreme court all weekend. they want a seat to watch historic arguments over whether or not president obama's health care law is constitutional. today is day one of arguments. the focus, should the high court postpone a decision since the law doesn't go into full effect

until 2014. the law requires what's called an individual mandate, meaning all americans must buy health insurance or face a fine. tomorrow's main question is, can congress force people to buy something? 26 states are opposed and some lawyers say if the court upholds the law, it could have far-reaching consequences. >> if the administration wins on this one, it is, frankly, hard to see what would be left of federalism as a concept in the united states. >> reporter: wednesday's focus will be if the individual mandate is unconstitutional, does that mean the entire law is struck down? these three days of argument will be the longest the supreme court has heard in 45 years. lawyers will have a total of six hours to state their cases. the obama administration is looking forward. >> we're confident it will be constitutional. and our focus right now, obviously there's going to be a process play out this week and the supreme court will deliver it. we'll continue to make sure we implement this law smartly. >> reporter: republicans say it

goes too far. >> americans have now come to their own conclusion. they don't like it. they think it's unconstitutional. and they want it repealed. >> reporter: a ruling will likely come later this year. now, if the court decides by law it has to postpone a decision on this until 2015, and that's when the americans who don't buy health insurance pay the first penalty, it would relieve the court of the burden of making a decision on the law before it's so close to a presidential election. tyrell? >> take a seat. this will take a while. susan mcginnis in washington, thank you. president obama is in seoul, south korea, this morning for an international nuclear security summit. notably absent is north korea. this morning the president had tough words for north korean leaders and their nuclear weapons program. the president warned there will be no rewards for provocation and now is the time to pursue peace. today we say, have the courage to pursue peace and give a better life to the people of north korea.
