Option A is correct: Natural Justice implies fairness, reasonableness, equity and equality. Natural Justice is a concept of Common Law, and it is the Common Law world counterpart of the American concept of ‘procedural due process’. Natural Justice represents higher procedural principles developed by judges which every administrative agency must follow in taking any decision adversely affecting the rights of a private individual.
