Coles v. Wood was recently applied by this Court in Knight v. Spadano[14] where it was held that the refusal by a judge of the Trial Division to make orders in the nature of certiorari and mandamus (and declarations) was interlocutory notwithstanding that there was no principal cause elsewhere, unlike the position in Coles v. Wood, where the main proceeding concerned the validity of search and arrest warrants and the application for prerogative relief was ancillary to that proceeding.[15] Mr Clelland sought to distinguish Knight v. Spadano on the basis that the Court in that case recognised that the applicant could make another application for like relief. Here, said counsel, the time limits have expired and, therefore, there was no real prospect of the appellant bringing another such proceeding. But such an argument disregards a critical aspect of the criteria for determining whether a decision is final or interlocutory, namely, whether the legal, as distinct from the practical, effect of the decision determines finally the rights of the parties. To determine that question one looks at the hypothetical situation. Thus, if it is possible, from a legal point of view, to bring another like proceeding, albeit on different grounds, the decision will ordinarily be considered to be interlocutory, notwithstanding that, from a practical point of view, it can be said that such an application is unlikely to be made.[16] I consider that, as in Knight, it is possible, from a legal point of view, for the appellant to bring another proceeding for like relief notwithstanding that the time limit fixed by Rule 56.02(1) has expired, and notwithstanding that "special circumstances" must be shown before the Court can grant an extension of time.[17]
