The natural justice principles referred to in sub section 3(d) are the underlying principles of fairness which guide the process of informed decision making.  The two fundamental rules of fair procedure are –

(1)    a man may not be a judge in his own cause;
(2)    a man’s defence must always be fairly heard.

The principles of natural justice are –

(i)    The right to a fair hearing which includes -
    (a)    the right to make representation before a decision is made;
    (b)    the right to call witnesses and have their testimony heard;
(ii)    The right to be heard by an unbiased Tribunal;
(iii)    The duty to act fairly;
(iv)   The right to have notice of charges brought against you and to know the particulars of the charges;
(v)    The right to reason for a decision.
