An ex post facto law refers to a law that prosecutes a person who has committed a crime, which was not an offense at the time it was committed, or adds onto an existing punishment. It is deemed unjust and is not allowed in most legal systems as it goes against the concept of justice and legal certainty.

An ex post facto law is a law that punishes someone for an action that was legal when it was done.

An ex post facto law is a law that is applied retroactively, meaning it punishes or changes the legal consequences of actions that were committed before the law was enacted. Such laws are generally considered unfair because they make something illegal after it has already been done, and many legal systems, including the U.S. Constitution, prohibit them to protect individuals’ rights.

An ex post facto law is a law that retroactively makes an action illegal or increases punishment for a crime after it was committed. Such laws are generally prohibited in many legal systems to ensure fairness and prevent misuse of legislative power.
