What rights do parties have during the hearings regarding witnesses?

The correct response is that all parties may call witnesses and present evidence, as this reflects the fundamental principles of fairness and due process in administrative hearings. In such proceedings, it is essential that all parties have the ability to present their case fully, which includes the right to call witnesses to testify and introduce relevant evidence that supports their argument. This process allows for a comprehensive examination of the facts and ensures that each party's perspective is considered.

Allowing each party to call witnesses also serves to enhance the adversarial nature of the hearing, promoting a more equitable and just outcome. This setup is vital in ensuring that decisions are made based on a complete and factual representation of the circumstances surrounding the case.

In contrast, options that suggest restrictions on who can call witnesses or cross-examine fail to uphold these standards of fair representation and due process, which are essential in any legal proceedings.
