To nullify something means to:

To nullify something refers to the act of rendering it invalid, void, or without value. This concept is often used in legal contexts where agreements, contracts, or laws can be nullified, indicating that they no longer have legal standing or enforceability. By stripping something of its worth or validity, nullification effectively negates its existence or effectiveness in a practical sense. Understanding this definition is crucial, as it highlights the transformation from a state of existence or agreement to a state of nonexistence or rejection.
