Who would be classified as a compellable witness in a hearing?

The classification of a compellable witness in a hearing involves understanding who can be legally required to provide testimony. In this context, the correct answer focuses on the investigated person or any individual who possesses relevant knowledge pertaining to the complaint. This broad classification encompasses those who are directly involved in the matter at hand, allowing for a comprehensive gathering of information that is crucial for the hearing's outcome.

The investigated person is central to the proceedings, as their testimony can shed light on the circumstances surrounding the complaint. Additionally, including anyone else who has knowledge of the situation ensures that all perspectives and potentially critical information can be presented, leading to a more informed decision-making process by the hearing committee.

In contrast, other options are limited. The Investigative Committee is focused on carrying out the investigation rather than being a witness. Expert witnesses can provide valuable insights, but they are typically called only when specific expertise is necessary, rather than being considered compellable in all instances. Finally, third parties associated with the investigation may have relevant information, but they may not be deemed compellable unless they directly relate to the matters of relevance in the complaint. Thus, the broad inclusion of the investigated person and anyone with knowledge makes the second choice the most accurate.
