/ˈnʌləti prəˈsidʒər/ – Phrase
Definition: thủ tục tiêu hủy, thủ tục vô hiệu hóa.
A more thorough explanation: A nullity procedure is a legal process used to challenge the validity of a contract, marriage, or other legal document. It is typically initiated when one party believes that the document is invalid due to a defect in its formation or execution. The nullity procedure seeks to have the document declared null and void, effectively canceling its legal effect.
Example: In the event of a breach of contract, the nullity procedure allows for the contract to be declared void and unenforceable by a court of law.
