Quote from Alexander Hamilton,
"The interpretation of the laws is the proper and peculiar province of the courts. A constitution is in fact, and must be, regarded by the judges as a fundamental law. It therefore belongs to them to ascertain its meaning as well as the meaning of any particular act proceeding from the legislative body. If there should happen to be an irreconcilable variance between the two, that which has the superior obligation and validity ought of course to be preferred; or in other words, the constitution ought to be preferred to the statute, the intention of the people to the intention of their agents."
