Ex post facto

by | Nov 1, 2023

Ex post facto – It means “from a thing done afterward” in English. In legal contexts, it refers to a law or regulation that retroactively changes the legal consequences of actions that were committed before the law was enacted. In many legal systems, ex post facto laws are prohibited because they can be unfair by punishing individuals for actions that were legal at the time they were committed.

  • Ex :- from or after
  • Post :- after or subsequent to
  • Facto :- fact or deed

ExampleWhen a government changes tax laws to increase rates for income earned in the previous year, affecting taxpayers who had already filed their returns based on the old rates.
