/ˈsuːpərˌviːnɪŋ ˌɪlɪˈɡæləti/ – Phrase
Definition: tình trạng bất hợp pháp phát sinh ngoài ý muốn.
A more thorough explanation: Supervening illegality refers to a situation where an action that was initially legal becomes illegal due to a change in law or circumstances. This term is often used in legal contexts to describe a situation where an existing contract or agreement becomes unenforceable or void because it violates a new law or regulation that was enacted after the contract was formed.
Example: The contract was rendered void due to supervening illegality, as the new law prohibited the type of transaction outlined in the agreement.
