Invalidates

To invalidate something means to prove that an argument, statement, or theory is not valid; to weaken or destroy the effectiveness or validity of something. It can involve revealing flaws, contradictions, or errors that render the original concept unsound or unusable. This act can be applied to laws, contracts, experiments, ideas, data, or claims, questioning their truth, legality, or reliability and therefore making them null.

Invalidates meaning with examples

• A critical discovery of significant errors and omissions by the research team invalidates the findings of the study, requiring a complete rework of the methodology before the conclusions can be reliably accepted by the scientific community.
• The discovery of a clause that was originally written in bad faith invalidates the contract and the court ruled that the agreement between the company and the contractor is therefore no longer binding or enforceable under law.
• When it was revealed that the key witness had a history of mental instability and was possibly paid off, it completely invalidates his testimony and significantly weakens the defense's case, opening them up to higher conviction rates.
