A more thorough explanation: Vitiation is a legal term that refers to the act of making something legally ineffective or void. It can occur when a contract or agreement is tainted by fraud, mistake, duress, or other factors that undermine its validity. When vitiation occurs, the contract may be considered null and void, and the parties may be released from their obligations under it.
Example: The contract was found to be void due to the vitiating factor of misrepresentation by one of the parties.
