“Nullification acts have been introduced in state legislatures all across the country, particularly in the last few months. According to one estimate at the Tenth Amendment Center, which tracks such things, there are more than 70 proposed bills to nullify federal laws and practices now in state legislatures, sometimes consciously labeled nullification, sometimes not. For example, 12 states have introduced proposals for state marijuana laws in defiance of federal regulations under the Controlled Substances Act of 1970. State laws against National Defense Authorization Act indefinite detention provisions have been introduced in almost half the states.”
