What is the role of a "witness" in a trial?

The role of a witness in a trial is to provide testimony and evidence relevant to the case. Witnesses are individuals who have firsthand knowledge about the events surrounding the trial and can offer their observations or expertise to the court. Their contributions can help establish the facts of the case, supporting the arguments presented by either the prosecution or defense.

Testimonies from witnesses can take many forms, including eyewitness accounts, expert opinions, or recollections of events pertinent to the case. This information is critical for the judge or jury to understand the context and details of the situation being adjudicated, ultimately assisting them in reaching an informed verdict.

The decision on guilt or innocence lies solely with the judge or jury, who evaluate all the evidence presented, including witness testimony. Additionally, the representation of the defendant or plaintiff is conducted by their respective legal counsels, while courtroom order is maintained by court officers, rather than being the responsibility of witnesses.
