What is the purpose of the cross-examination phase?

The purpose of the cross-examination phase primarily revolves around questioning the credibility and reliability of a witness’s testimony. During this stage, the legal representatives of the opposing party have the opportunity to challenge the statements made by a witness during direct examination. This can involve highlighting inconsistencies, biases, or motives that might affect how the witness's testimony should be interpreted. By successfully casting doubt on a witness's credibility, the cross-examiner aims to persuade the jury or judge to disregard some or all of the information presented.

In contrast, the other options do not accurately capture the primary goal of cross-examination. While providing information to the jury and summarizing a case are important aspects of a trial, they typically occur during direct examination or closing arguments rather than during cross-examination. Introducing new evidence is also generally not allowed during cross-examination, as this phase focuses on the existing testimony rather than bringing in fresh material. Thus, questioning a witness's credibility is, in essence, the core focus of cross-examination.
