Abstract Natural Justice is a key principle in common English law which requires the procedural fairness in the administrative law. In relating to the natural justice principle ‘’Audi Alteram Partem’’ implies that no one should condemned without fair hearing. This principle demonstrates a fair hearing before every decision which is affecting the individuals’ rights. The main component of the fair hearing includes the cross examination, legal representation and prior notice. In the case of Ridge v Baldwin it is clearly mentioned that if the rules are ignored the decision can be declared. An early example of applying the fair hearing rule is Bagg’s case, where judicial review was sought through the mandamus. In this case made it clear that all proceedings without a fair hearing are invalid, supporting the Court king’s Bench stance. Natural Justice has two main doctrines.’audi alteram partem’ and ‘nemo judex in causa sua’ which means no one should judge their own case while the right to a fair hearing is absolute and the rule against bias has some exceptions. Many constitutions like Nigeria include provisions for fair hearings in civil disputes. Sir Mattew Hale, in 1676 points out the importance of hearing both sides before deciding. The idea was reinforced in the Cooper v Wandsworth Board of Works, where the division of fairness was mentioned.
