What constitutes "witness testimony"?

Witness testimony is defined as an account provided by an individual who has been sworn in under oath to tell the truth in a legal proceeding. This testimony is typically based on the witness's personal knowledge or observations related to the case, and it plays a critical role in helping the court understand the facts and circumstances at hand.

This type of testimony is essential in establishing the evidence that can support claims made by either party in a case. It differs significantly from documents or other forms of evidence because it involves the personal experience and perspective of a witness, which can provide unique insights and factual background that are not captured in written records.

The other options do not accurately describe witness testimony. Documents submitted by a witness do not constitute testimony; they are separate pieces of evidence. Lawyer arguments, while critical to the legal process, do not qualify as testimony since they are interpretations and strategies rather than firsthand accounts. Lastly, excluding any prior legal knowledge of the witness does not accurately reflect the nature of testimony, as a witness might bring relevant experience that informs their account, thus enriching the testimony provided.
