"Reject" is a pretty harsh word, but I understand your meaning. Under the 10th amendment of the U.S. Constitution, states have certain political rights. They can, for example, write laws that creatively expand upon a federal law without conflicting with the federal law. One such area of law is gun rights. Although the 2nd amendment to the U.S. Constitution says that you have the right bear arms, states can and do put restrictions on the carrying of guns by requiring licenses to carry guns. Requirements to apply for these licenses differ widely. Most states restrict gun licenses to those who have not been convicted of a felony, are of a particular age (18 or 21), etc., etc. In this way, states maintain some semblance of community standards without "rejecting" federal law.

The Doctrine of Nullification.
Calhoun believed in states rights above all. He espoused the doctrine of nullification which meant that states could nullify or reject Federal Laws they did not want to obey. He also thought states had the right to leave the federal union if they wished.
Nullification is the theory that states have the right to invalidate federal laws they deem unconstitutional. It is based on the belief that the states are sovereign entities with the power to challenge and reject laws imposed by the federal government. This principle was most notably debated during the early 19th century in the context of disputes over state vs. federal authority.
