"The grounds upon which this appeal is brought are that the Industrial Tribunal erred in law in that although the appellant's last day at work was 27.2.97, this was in fact the date upon which she received one month's notice. Consequently the effective date of termination for the purposes of making a claim is 27.3.97. This means that the IT1 form received by the Industrial Tribunal on 27.5.97 was within the three months time limit. .... "
"We would wholly endorse what was said by Arnold J. and what would seem to be setting out the settled and accepted practice in this appeal tribunal, and we would not seek to depart from what he said - except, in our view, that where the matter raises the question of jurisdiction, (that is to say, whether the industrial tribunal claimed jurisdiction, or refused to accept jurisdiction) it is open, even if that matter was not raised before the industrial tribunal, to argue it before the appeal tribunal. It would seem to us quite contrary to any principles of justice not so to hold."
"There were two possible ways of arguing the case on behalf of the employee, one of which was allowed to be advanced by the appeal tribunal although it had not been advanced below. Here we have two possible ways in which the case could have been mounted by the employee when the matter came before the industrial tribunal. We have come to the conclusion that the statement to be found in House v Emerson Electric Industrial Controls is not to be construed as meaning that any and every point on jurisdiction, whether or not it may involve the adducing of further evidence, can be taken at any stage in the proceedings. For that in our view would be much too wide a principle. In each case in our view, the court has to decide on balance whether justice requires that the new point should be allowed to be taken."
"It does not however follow from this that all jurisdictional points must be allowed at any stage even if they involve a further hearing to establish further facts. In our view in each case the appeal tribunal has to decide on balance whether justice requires that the new point should be allowed to be taken. If it appears on existing evidence that the decision appealed from is a nullity that will be a consideration of overwhelming strength. Where what is relied upon is a chance of establishing a lack of jurisdiction by calling fresh evidence which was always available the case is far less straightforward."
