What is the primary purpose of cross-examination?

The primary purpose of cross-examination is to ask a witness after they have already been examined. This phase of questioning allows the opposing party to challenge the credibility, reliability, and accuracy of the witness's testimony provided during the direct examination. During cross-examination, the attorney can explore inconsistencies, highlight biases, or uncover any lack of knowledge the witness may have regarding the case. It serves as a critical mechanism in legal proceedings to ensure thorough fact-finding and helps to test the strength of the evidence presented.

Other options do not accurately capture the essence of cross-examination. For instance, while leading questions may be used during this phase, they are not the primary purpose; they're simply a technique utilized. Introducing new evidence is not the focus during cross-examination, as this process is specifically aimed at assessing previously presented testimony. Submitting a formal objection refers to a procedural action rather than a purpose of questioning a witness. Thus, the choice about asking a witness following their examination aligns perfectly with the function and objective of cross-examination in the courtroom.
