"The application was refused. The dates of the allegations are clearly set out in Section 10 of each of the Originating Applications.
"An Industrial Tribunal shall not consider a complaint under Section 54 unless it is presented to the tribunal before the end of three months beginning when the act complained of was done."
"In giving its decision in interlocutory proceedings an industrial tribunal is exercising its discretion, but that discretion must be exercised within the powers given to the industrial tribunal on that issue and within the relevant legal principles which have been evolved largely through decisions of appellate courts. It is the exercise of a judicial discretion. It seems to us desirable, and indeed we would have expected, that the same principle would apply to interlocutory appeals as for final appeals even though the former will in the main be the result of the exercise of a discretion. Thus, in examining an interlocutory order of an industrial tribunal or of a chairman sitting alone we would define three issues: (a) Is the order made one within the powers given to the tribunal? (b) Has the discretion been exercised within guiding legal principles? (e.g. as to confidential documents in discovery issues); (c) Can the exercise of the discretion be attacked on the principles in Associated Provincial Picture Houses v. Wednesbury Corporation [1948] 1 K.B.223?"
"The words "in all the circumstances of the case" refer, as we think, to the actual facts of the matter in so far as they are relevant to the matter under consideration in Section 76(5). "The case" does not refer, we think, to the entire complaint which, if time were extended, would have to be investigated. The words refer to the actual facts so far as relevant to the matter in hand."
"Because it is such a wide discretion conferred upon an industrial tribunal, the task which the appellant has in such a case is a heavy one. Really he must show, if he is to succeed upon appeal, that the industrial tribunal demonstrably took a wrong approach to the matter, or that they took into account facts which they ought not to have done, or that they failed to take into account facts which they should have done, or, as a last resort which is always open upon an appeal, that the decision was so unreasonable in all the circumstances that no reasonably instructed tribunal could have reached it."
"There are many occasions when it is a convenient course to have a preliminary issue decided in advance of the main hearing of a complaint where it is felt that the decision on the preliminary issue will shorten the main hearing. If that is so, it can save time for the industrial tribunal and help listing to have a preliminary issue decided. An obvious instance is where there is an issue entirely separate from the disputes on the merits of the complaint as, for instance, whether the complaint was lodged in due time or not."
"A.......tribunal may nevertheless consider any such complaint.....which is out of time if in all the circumstances of the case, it considers that it is just and equitable to do so."
