Cross-Examination under the Law of Evidence
Cross-examination is one of the most powerful and essential tools in the judicial process. Under Sections 137 and 138 of the Indian Evidence Act, 1872, cross-examination is the process in which the opposite party questions a witness to test the accuracy, credibility and truthfulness of his testimony. It is widely regarded as the “greatest legal engine ever invented for the discovery of truth,” because it allows the court to filter genuine facts from fabricated or exaggerated statements. The primary purpose of cross-examination is not merely to contradict a witness but to ensure that the evidence presented is reliable, consistent, and free from bias. Through this process, courts determine the weight that should be given to each piece of testimony. Without cross-examination, the trial would become one-sided, and the risk of wrongful convictions or unjust acquittals would significantly increase.
Cross-examination serves as a safeguard against falsehood because it compels the witness to answer questions relating not only to the facts deposed in examination-in-chief but also to their credibility, prior conduct, or motives. As per Section 146, questions may be asked to test the veracity of the witness, to discover their position in life, or to shake their credit through injurious answers. This provision ensures that the court gets a complete picture of the witness’s reliability. Thus, cross-examination is not merely a procedural formality but the heart of adversarial justice. It is through this rigorous questioning that hidden facts surface, contradictions emerge, and the real truth becomes accessible to the judge.
Nature of Cross-Examination
The nature of cross-examination is adversarial, confrontational, and investigative. It allows the counsel to dissect every statement made by the witness to determine whether it withstands scrutiny. Unlike examination-in-chief, where only open-ended, non-leading questions are permitted, cross-examination allows the asking of leading questions, i.e., questions that suggest the answer. This is authorized under Section 143, which states that leading questions may be asked as a matter of right during cross-examination. This feature makes cross-examination more aggressive and results-oriented.
Furthermore, cross-examination is broad in scope. A witness may be questioned on any relevant fact, irrespective of whether it was raised in the examination-in-chief. The intention is to uncover inconsistencies, motives, prejudices, or previous conduct relevant to the credibility of the witness. Courts have repeatedly emphasized that the purpose is not to harass or insult the witness, but to bring clarity and authenticity to the testimony. A well-conducted cross-examination can entirely change the direction of a case by exposing exaggerations, contradictions, and falsehoods that would otherwise remain hidden.
The nature of cross-examination also includes a procedural safeguard: it must be fair and conducted within legal boundaries. Section 148 allows the court to decide whether a witness must answer questions that could injure their reputation unless the truth of the accusation has a strong bearing on the case. This balances the rights of the parties and prevents misuse of the process. Thus, cross-examination is a highly structured, procedurally regulated, yet strategically flexible tool to bring out the truth.
Scope of Cross-Examination
The scope of cross-examination is extremely wide. As per Section 138, the cross-examination need not be confined to the facts stated in examination-in-chief. It may extend to all matters relevant to the issue and also to matters affecting the credibility of the witness. This means the opposite party can question the witness on any fact that may help the court in understanding the truth, even if it appears indirectly connected.
The scope includes testing the witness on prior inconsistent statements under Section 155(3), where the defense may confront the witness with contradictions from previous statements recorded under Section 161 CrPC or before a Magistrate. It also allows questioning regarding the witness’s relationship with the parties, possible motives for testifying falsely, or financial interest in the outcome of the case. Questions about character, bias, past criminal conduct, or professional competence may also be explored if they impact credibility.
Cross-examination is also used strategically to elicit favorable facts from an adverse witness. Sometimes, the opposing counsel extracts admissions or clarifications that strengthen their own case. The witness may unintentionally reveal facts that undermine their earlier statements. Thus, cross-examination is not only for discrediting but also for discovering supportive evidence. In essence, its scope is as wide as the search for truth allows, limited only by the necessity of relevance and fairness.
Real-Time Example
Consider a murder trial where the prosecution’s key eyewitness claims he saw the accused stabbing the victim at 10 PM under a streetlight. During cross-examination, the defense counsel asks leading questions to challenge visibility, distance, lighting, and the witness’s position. The witness eventually admits that the streetlight was not functioning on the date of the incident—a fact recorded in municipal repair logs. He further admits he was standing nearly 50 meters away. These revelations create serious doubt about the reliability of his testimony. Thus, a statement that initially appeared strong becomes weak through effective cross-examination, demonstrating its power in discovering truth and preventing wrongful conviction.
