What is meant by the Constitution's declaring itself the supreme law of the land? Section 5. _The Federal Judiciary_. [Sidenote: Need for a federal judiciary.] The creation of a federal judiciary was the second principal feature in the Constitution, which transformed our country from a loose confederation into a federal nation, from a _Band-of-States_ into a _Banded-State_. We have seen that the American people were already somewhat familiar with the method of testing the constitutionality of a law by getting the matter brought before the courts.[27] In the case of a conflict between state law and federal law, the only practicable peaceful solution is that which is reached through a judicial decision. The federal authority also needs the machinery of courts in order to enforce its own decrees. [Footnote 27: See above p. 194.]
