The primary role of corroborating evidence in a legal case is to reinforce or support existing evidence. Corroborating evidence serves to bolster the credibility of the primary evidence presented, making it more persuasive and reliable. This type of evidence helps to confirm that the facts presented are accurate, consistent, and help substantiate the overall argument or claim being made in the case.

For example, if a witness testifies about seeing an event occur, corroborating evidence might include surveillance footage or another witness who observed the same event. This additional support increases confidence in the validity of the witness's account, thereby strengthening the overall case.

Introducing new facts would not align with the purpose of corroborating evidence, as it focuses on reinforcing what is already established rather than bringing in new information. Similarly, the roles of contradicting testimonies or providing personal opinions do not serve to uphold the integrity of existing evidence, which is the crucial function of corroborating evidence in the legal context.
