> 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.

I believe this applies to the USA as a whole as well, not just to states (Bolling v. Sharpe (1954) according to ChatGPT). One could argue the law is unconstitutional because it applies a punishment without due process.
