Testimony is a type of evidence that involves a statement made by a witness under oath, often in a legal setting such as a courtroom. This evidence can provide firsthand accounts of events, helping to establish facts in a case. Testimony can come from various sources, including eyewitnesses, experts, or individuals involved in the situation. In legal proceedings, testimony is crucial for both the prosecution and defense. It can support or challenge claims made by either side. The credibility of the witness, as well as the clarity and consistency of their testimony, can significantly impact the outcome of a trial involving judges, jurors, and lawyers.
