Natural Justice - Background

Background

Natural justice is a term of art that denotes specific procedural rights in the English legal system and the systems of other nations based on it. It is similar to the American concepts of fair procedure and procedural due process, the latter having roots that to some degree parallel the origins of natural justice.

Although natural justice has an impressive ancestry and is said to express the close relationship between the common law and moral principles, the use of the term today is not to be confused with the "natural law" of the Canonists, the mediaeval philosophers' visions of an "ideal pattern of society" or the "natural rights" philosophy of the 18th century. Whilst the term natural justice is often retained as a general concept, in jurisdictions such as Australia and the United Kingdom it has largely been replaced and extended by the more general "duty to act fairly". Natural justice is identified with the two constituents of a fair hearing, which are the rule against bias (nemo iudex in causa sua, or "no man a judge in his own cause"), and the right to a fair hearing (audi alteram partem, or "hear the other side").

The requirements of natural justice or a duty to act fairly depend on the context. In Baker v. Canada (Minister of Citizenship and Immigration) (1999), the Supreme Court of Canada set out a list of non-exhaustive factors that would influence the content of the duty of fairness, including the nature of the decision being made and the process followed in making it, the statutory scheme under which the decision-maker operates, the importance of the decision to the person challenging it, the person's legitimate expectations, and the choice of procedure made by the decision-maker. Earlier, in Knight v. Indian Head School Division No. 19 (1990), the Supreme Court held that public authorities which make decisions of a legislative and general nature do not have a duty to act fairly, while those that carry out acts of a more administrative and specific nature do. Furthermore, preliminary decisions will generally not trigger the duty to act fairly, but decisions of a more final nature may have such an effect. In addition, whether a duty to act fairly applies depends on the relationship between the public authority and the individual. No duty exists where the relationship is one of master and servant, or where the individual holds office at the pleasure of the authority. On the other hand, a duty to act fairly exists where the individual cannot be removed from office except for cause. Finally, a right to procedural fairness only exists when an authority's decision is significant and has an important impact on the individual.
