Which of the following is NOT one of the rules of procedural fairness?

The concept of procedural fairness, also known as natural justice, encompasses specific principles that ensure fairness in legal proceedings. Among these principles, the "duty to inform opponents" is not typically recognized as a standalone rule of procedural fairness.

The right to an interpreter is important, particularly in jurisdictions where language barriers may impede a party's understanding and participation in legal proceedings. This ensures that individuals who may not be proficient in the language of the court can fully understand the proceedings and communicate effectively.

Legitimate expectation pertains to a party's ability to expect that certain processes or practices will be followed based on past behavior or guidelines outlined by an authority. This expectation is crucial in maintaining fairness and consistency in decision-making processes.

Freedom from bias is a foundational principle of procedural fairness, ensuring that decision-makers are impartial and do not have personal stakes in the outcome of a case. This is critical in upholding the integrity of legal proceedings and instilling public confidence in the judicial system.

In contrast, while the duty to inform opponents is a concept related to fairness in the broader context of legal proceedings, it does not specifically fall under the traditional categories of procedural fairness rules that focus primarily on impartiality, the right to a fair hearing, and the right to present one’s case.
