From Jake Towne:

A talk given May 20, 2010 to the Concerned Citizens of Upper Perkiomen Valley for Smaller Government on the concept of nullification. Nullification is one of the checks the states have on the federal government where the state refuses to comply with federal law — which are deemed harmful to the state and usually assume powers not delegated by the state to the federal government. Nullified federal laws are deemed null and void in the state(s) where passed and have no force.
