/ˈnʌləti keɪs/ – Phrase
Definition: vụ án về hành vi pháp lý vô hiệu.
A more thorough explanation: A nullity case refers to a legal proceeding in which a court is asked to declare a marriage or other contract void or invalid from its inception, as if it never existed. This can be due to various reasons such as lack of capacity, fraud, or other legal defects that render the agreement or marriage null and void.
Example: In the nullity case, the court found that the contract was void due to a lack of capacity of one of the parties to enter into a legally binding agreement.
