Nullification was a well settled concept by the year 1798. Which is why it is often referred to as the rule of 98‘. Also as the Kentucky or Virginia resolutions.
Nullification is based on the idea that the Constitution lists very definite and limited powers delegated to the Federal government by the sovereign States, and that when they do things that we did not authorize them to do, that the States and the people have the right and the duty not to follow those laws.
Nullification is being used today by states to nullify the Obama health mandates, the real ID drivers license mandates, federal marijuana laws, and many other unconstitutional federal mandates.
