/ɛks poʊst ˈfæktoʊ ˌæplɪˈkeɪʃən/ – Phrase
Definition: đơn khiếu nại về sự kiện đã xảy ra từ trước.
A more thorough explanation: “Ex post facto application” refers to the retroactive application of a law or regulation to events that occurred before the law was enacted. This can have implications for individuals who may be subject to penalties or consequences for actions that were legal at the time they were committed but are now prohibited by the new law.
Example: The new law cannot have an ex post facto application, meaning it cannot be applied retroactively to punish individuals for actions that were legal at the time they were committed.
