The principles stated in the resolutions became known as the "Principles of '98". Adherents argued that the states could judge the constitutionality of central government laws and decrees. The Kentucky Resolutions of 1798 argued that each individual state has the power to declare that federal laws are unconstitutional and void. The Kentucky Resolution of 1799 added that when the states determine that a law is unconstitutional, nullification by the states is the proper remedy. The Virginia Resolutions of 1798 refer to "interposition" to express the idea that the states have a right to "interpose" to prevent harm caused by unconstitutional laws. The Virginia Resolutions contemplated joint action by the states.
