about four posts prior to this one i first entered into the nullification fracas, led there by a friend who sent me the lew rockwell article. the tenth amendment is the origin in the constitution for this discussion and its been ongoing in various states since the founding. its the law and has virtually been unused since its origin;

Acting Attorney General Matthew Whitaker's comments on states' rights to nullify unconstitutional federal laws have come under attack this week, but he is taking the position of our founders by advancing nullification.
For those unaware, nullification is rooted in the Tenth Amendment to the Constitution, which plainly states that if the states, who are the creators of the federal government, have not specifically given them authority, that authority rests with the states and the people of the state.

The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
By the way, notice the people and the states are distinguishable.  They are not synonyms for the state.  Some powers are delegated to the states that are not delegated to the federal government, and some powers are inherently given to the people by their Creator and not given to the state nor the federal government.
CNN legal analyst Renato Mariotti uttered these utterly stupid words:

"'Nullification' was a legal argument made by Southerners before the Civil War who believed their states could 'nullify' federal law. That argument was discredited after their defeat in the Civil War, but it was made again by racists opposing desegregation. And now by Whitaker."

The War of Northern Aggression did not discredit that argument.  In my opinion, it was simply the result of the South not cutting the head off of the snake in DC and destroying the tyrant, Abraham Lincoln............https://freedomoutpost.com/acting-attorney-general-matthew-whitakers-comments-on-nullification-is-the-founders-position/
