“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.”
Nullification is a method by which states prevent the enforcement of Federal authority in instances when the Constitution does not give the central government the right of encroachment upon states’ rights.
In the Texas Constitution there are at least three sections of Article I, Bill of Rights that plainly establish legal (and binding) grounds for nullification.
Section 1 reads: “Texas is a free and independent State, subject only to the Constitution of the United States, and the maintenance of our free institutions and the perpetuity of the Union depend upon the preservation of the right of local self-government, unimpaired to all the States.”
Section 2 reads: “All political power is inherent in the people, and all free governments are founded on their authority, and instituted for their benefit. The faith of the people of Texas stands pledged to the preservation of a republican form of government, and, subject to this limitation only, they have at all times the inalienable right to alter, reform or abolish their government in such manner as they may think expedient.”
Section 29 of the Texas Bill of Rights, reads: “To guard against transgressions of the high powers herein delegated, we declare that everything in this ‘Bill of Rights’ is excepted out of the general powers of government, and shall forever remain inviolate, and all laws contrary thereto, or to the following provisions, shall be void.”
