Natural Justice in UK Law

For a long time the Courts have, without objection from Parliament, supplemented procedure laid down in legislation where they have found that to be necessary for this purpose. But before this unusual kind of power is exercised it must be clear that the statutory procedure is insufficient to achieve justice and that to require additional steps would not frustrate the apparent purpose of the legislation.

What they comprehend has been analysed and described in many authorities. We do not search for prescriptions which will lay down exactly what must, in various divergent situations, be done. The principles and procedures are to be applied which, in any particular situation or set of circumstances, are right and just and fair. Natural justice, it has been said, is only "fair play in action".

In particular, it is well-established that when a statute has conferred on any body the power to make decisions affecting individuals, the courts will not only require the procedure prescribed by the statute to be followed, but will readily imply so much and no more to be introduced by way of additional procedural safeguards as will ensure the attainment of fairness.

It is only too easy in a complex case for a party who is dissatisfied with the decision of an adjudicator to comb through the adjudicator's reasons and identify points upon which to present a challenge under the labels "excess of jurisdiction" or "breach of natural justice". The task of the adjudicator is to find an interim solution which meets the needs of the case. The need to have the "right" answer has been subordinated to the need to have an answer quickly.

But there are many cases where, although the tribunal had jurisdiction to enter on the enquiry, it has done or failed to do something in the course of the enquiry which is of such a nature that its decision is a nullity. It may in perfect good faith have misconstrued the provisions giving it power to act so that it failed to deal with the question remitted to it and decided some question which was not remitted to it.

Secondly, trials are conducted on the basis of the principle of natural justice. A party has a right to know the case against him and the evidence on which it is based. He is entitled to have the opportunity to respond to any such evidence and to any submissions made by the other side. The other side may not advance contentions or adduce evidence of which he is kept in ignorance. The Privy Council said in the civil case of Kanda v Government of Malaya [1962] AC 322, 337:

I turn secondly to the proper purpose of the remedy of judicial review, what it is and what it is not. His was a dissenting judgment but the dissent was not concerned with this point. Judicial review is concerned, not with the decision, but with the decision-making process. Unless that restriction on the power of the court is observed, the court will in my view, under the guise of preventing the abuse of power, be itself guilty of usurping power.
