/tə ˈvɪʃɪˌeɪt ə ˈkɒntrækt/ – Phrase
Definition: làm mất hiệu lực một hợp đồng.
A more thorough explanation: To vitiate a contract means to render it void or invalid due to a defect or flaw that undermines its legal validity or enforceability. This defect could be caused by factors such as fraud, misrepresentation, duress, undue influence, mistake, or illegality. When a contract is vitiated, it is considered as though it never existed, and the parties are released from their obligations under the contract.
Example: The fraudulent misrepresentation made by one party served to vitiate the contract, rendering it voidable.
