Ex Post Facto Clause: A Key Protection Against Retroactive Legislation
Definition & Meaning
The Ex Post Facto Clause is a provision in the U.S. Constitution that prohibits states and the federal government from enacting laws that apply retroactively to punish individuals for actions that were not illegal at the time they were committed. Specifically, Article I, section 10, clause 1 of the Constitution forbids states from passing such laws, while Article I, section 9, clause 3 imposes the same restriction on Congress. This clause is designed to protect individuals from unfair legal consequences and is limited to criminal laws, meaning it does not apply to civil matters. However, retroactive civil laws may still violate other constitutional protections, such as the Contract Clause or the Due Process Clause.

Real-world examples
Here are a couple of examples of abatement:
Example 1: A state passes a law making it illegal to use a specific type of software retroactively. If a person used that software before the law was enacted, they cannot be prosecuted under this new law due to the Ex Post Facto Clause.
Example 2: A new law increases penalties for a crime committed in the past. If a person committed the crime before the law was passed, they cannot be punished under the new, harsher penalties. (hypothetical example)
