The Hearing Rule
For ensuring that respect is being given to these rights, the authority taking decision must provide an opportunity to both for preparing and presenting evidence and for responding to the argumentative statements that are being presented by the opposite side (Hall and Purcell, 2012). When the investigation is conducted with respect to a complaint, it is relevant that the individual against whom the complaint is filed, is suggested to provide maximum level of facts and information, and with respect to the opportunity of replying to the allegations imposed.
The Bias Rule
According to this rule, it has been stated that no one will be making judgements over her or his own case. This has been identified as the basic requirement that the authority making the decision has to be unbiased when the hearing is being accorded or the decision is being made (Barrett, 2000). In addition to this, the decision makers and investigators must act without any biasness within the procedures that are in connection with the process in which decision is made.
The Evidence Rule
This rule is that a decision of administration must be made on the basis of evidence material or logical proof. Decision makers and investigators should have the ability of clearly pointing out the evidence over which the determination or inference is based (Labour Research Department, 2005). In addition to this, it is important to state that the decision must not be made on the basis of mere suspicion or speculation.
