/nɛgətɪv tɛstəˈmoʊni/ – Phrase
Definition: lời chứng phủ định.
A more throughout explanation: Negative testimony refers to evidence given by a witness that tends to disprove or contradict a fact or claim asserted by another party in a legal proceeding. It involves the witness stating that something did not happen or was not observed, rather than affirmatively stating what did happen or was observed.
Example: In a court case, the witness provided negative testimony by stating that they did not see the defendant at the scene of the crime.
