The first section of the fourteenth amendment,-which is the one relied on,-after declaring who shall be citizens of the United States, and of the several states, is prohibitory in its character, and prohibitory upon the states. It declares that [109 U.S. 3, 11] 'no state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.' It is state action of a particular character that is prohibited. Individual invasion of individual rights is not the subject- matter of the amendment. It has a deeper and broader scope. It nullifies and makes void all state legislation, and state action of every kind, which impairs the privileges and immunities of citizens of the United States, or which injures them in life, liberty, or property without due process of law, or which denies to any of them the equal protection of the laws. It not only does this, but, in order that the national will, thus declared, may not be a mere brutum fulmen, the last section of the amendment invests congress with power to enforce it by appropriate legislation. To enforce what? To enforce the prohibition. To adopt appropriate legislation for correcting the effects of such prohibited state law and state acts, and thus to render them effectually null, void, and innocuous. This is the legislative power conferred upon congress, and this is the whole of it. It does not invest congress with power to legislate upon subjects which are within the domain of state legislation; but to provide modes of relief against state legislation, or state action, of the kind referred to.
It would seem to me that the Courts reasoning would completely over turn every State level gun ban, CCW, and open carry restriction in the Nation.
Further, it also would over turn some 90% of the Federal laws including the NFA of '34 and the GCA of '68. Assuming, of course, that anyone in a position of "power" cared to do so. It isn't in their best interests to let go of this pilfered power.
That, and folks like our erstwhile Brady Troll would need to find other employment.
