What type of witness is primarily concerned with the facts they have personally observed?

The type of witness who is primarily concerned with the facts they have personally observed is known as a fact witness. This witness provides testimony based on their direct experience and observations related to the case at hand. They do not provide opinions or interpretations; instead, their role is to convey what they saw, heard, or experienced in relation to the event in question.

Fact witnesses play a crucial role in legal proceedings as their firsthand accounts can significantly impact the understanding of the events being investigated. Their testimony helps to establish a factual basis for the case, often serving to support or refute claims made by other parties.

In contrast, other types of witnesses, such as expert witnesses, typically offer opinions based on specialized knowledge or expertise, while character witnesses testify about a person's character rather than the facts of the case. Vicarious witnesses are not commonly recognized in legal terminology and typically do not fit within the traditional categories of witness types recognized in legal settings.
