"In determining whether, in a particular case, there is a duty to give reasons and the extent of it, regard should, in my opinion, be had to the function to be served by the giving of reasons. Thus, the statement of reasons may be necessary to enable a party to exercise his right of appeal or such other rights, as he may have to contest the decision: this is one of the conventional functions of the requirement: see Pettitt v Dunkley (at 387, 388). But, in my opinion, the requirement that reasons be given should not be limited to cases where there is an appeal. There is as yet no finally authoritative decision on this question. I think that the requirement should be seen as an incident of the judicial process. However, the fact that the function of the requirement is, at least in part, to allow a party to exercise appeal rights is of significance in determining the extent of the duty and what will be a discharge of it. Thus, in some cases where ordinarily an appeal is not contemplated, there may not be a need for reasons. Thus, in England, it has been said that reasons need not be given in certain procedural applications: see Capital and Suburban Properties Ltd v Swycher [1976] Ch 319 at 325, 326. In such cases, and in cases of, eg, applications for leave, where the considerations of fact and law are clear, reasons need not ordinarily be given.
