KEVAN MOORE, BARNESVILLE, GEORGIA: Hello, my name is Kevan Moore. I'm from Barnesville, Georgia. And my question is, how did it come about that our court systems are asked to interpret laws set forth by Congress?</s>ROGER COSSACK, CNN LEGAL ANALYST: There's a very famous case in American jurisprudence called Marbury vs. Madison. Every law student studies it. In the early part of our history, there was a debate about what exact role the courts could play. The courts were looked upon, perhaps, as the weakest of the three branches of government. And in Marbury vs. Madison, the holding in that case was that the courts did have the power to interpret legislation that was passed by Congress. And it was a very clever decision because, in fact, the court set up its own abilities and defined for itself the role that it could play. And while, in that particular case, they held that the legislation or that, in fact, the facts that were in Marbury vs. Madison were OK and were not going to be changed by the court -- but it did establish the principle of the courts being able to be an equal partner along with the other two branches of government.
