/ʌnˈlɔfəl ˌæb ɪˈnɪʃiˌoʊ/ – Phrase
Definition: bất hợp pháp ngay từ đầu.
A more thorough explanation: “Unlawful ab initio” is a legal term that means something is considered illegal or invalid from the beginning or inception. It indicates that an action, contract, or decision was unlawful from the start and therefore has no legal effect.
Example: The court declared the contract to be unlawful ab initio, meaning it was invalid from the beginning.
