What is the aim of impeaching a witness?

Impeaching a witness serves the crucial purpose of questioning the credibility of the evidence or testimony they provide. This process allows attorneys to challenge the reliability or truthfulness of what a witness has said, ultimately impacting the weight of their testimony in the eyes of the judge or jury.

When a witness's credibility is successfully undermined, it can lead to significant implications for the overall case, possibly affecting the outcome of a trial. The aim is not to make the witness leave the courtroom, eliminate them entirely from the trial, or reinforce their statements; rather, it focuses specifically on scrutinizing their reliability and the accuracy of their evidence.
