Full Definition Of Ex Post Facto Clause

The Ex Post Facto Clause in the United States Constitution prevents the government from enacting laws that retroactively penalize individuals for actions that were not illegal when they were committed. For instance, if a law were to be passed today criminalizing the wearing of blue shirts, and someone were to be arrested and punished for wearing a blue shirt yesterday, this would violate the Ex Post Facto Clause. This clause serves to safeguard individuals from arbitrary and unfair punishment by the government. It ensures that people are only penalized for actions that were illegal at the time they were committed, rather than for actions that were legal at the time but later deemed illegal.
