Cross-examination is a legal process in which a lawyer questions a witness who has already provided testimony during a trial. This questioning aims to challenge the witness's statements, clarify details, and uncover inconsistencies. It is a critical part of the adversarial legal system, helping to ensure that all relevant information is considered. During cross-examination, the lawyer may use leading questions, which suggest their own answer, to guide the witness's responses. This technique helps to test the credibility of the witness and strengthen the case for the defense or prosecution. Effective cross-examination can significantly influence the outcome of a trial.
