“My Lords, I think it unnecessary to refer by name or to quote from, any of the often-cited authorities in which the courts have explained what is essentially an intuitive judgment. They are far too well known. From them, I derive that (1) where an Act of Parliament confers an administrative power there is a presumption that it will be exercised in a manner which is fair in all the circumstances. (2) The standards of fairness are not immutable. They may change with the passage of time, both in the general and in their application to decisions of a particular type. (3) The principles of fairness are not to be applied by rote identically in every situation. What fairness demands is dependent on the context of the decision, and this is to be taken into account in all its aspects. (4) An essential feature of the context is the statute which creates the discretion, as regards both its language and the shape of the legal and administrative system within which the decision is taken. (5) Fairness will very often require that a person who may be adversely affected by the decision will have an opportunity to make representations on his own behalf either before the decision is taken with a view to producing a favourable result; or after it is taken, with a view to procuring its modification; or both. (6) Since the person affected usually cannot make worthwhile representations without knowing what factors may weigh against his interests, fairness will very often require that he is informed of the gist of the case which he has to answer.”
“Natural justice requires that the procedure before any tribunal which is acting judicially shall be fair in all the circumstances, and I would be sorry to see this fundamental general principle degenerate into a series of hard-and-fast rules. 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.”
“There has been a growing and unwelcome tendency by first instance courts and, dare I say it, this court as well to depart from the starting point set out in rule [44.2(2)(a)] too far and too often. Such an approach may strive for perfect justice in the individual case, but at huge additional cost to the parties and at huge costs to other litigants because of the uncertainty which such an approach generates...”
