"Subject to subsection (4), an industrial tribunal shall not consider a complaint under this section unless it is presented to the tribunal before the end of the period of three months beginning with the effective date of termination or within such further period as the tribunal considers reasonable in a case where it is satisfied that it was not reasonably practicable for the complaint to be presented before the end of the period of three months."
"Accordingly the vital question is this: could the solicitors reasonably have expected the letter to be delivered in the ordinary course of post on the Friday? As we have indicated, the industrial tribunal do not deal with that question, nor, indeed, was the evidence presented to them on the subject complete. We have been invited to bring our own knowledge and experience to bear on this question, and we have been offered the knowledge and experience of the representatives of the parties. But a question of that kind is a question of fact and not one to be decided by speculation or guesswork.
"For clarity, we repeat: the question is, could the solicitors reasonably have expected the letter to be delivered in the ordinary course of post on the Friday? If the answer to that is `yes', then in our judgment, unless some quite new circumstances are discovered, the case is one which falls within paragraph 21 (4) where it is not `reasonably practicable' for the complaint to be presented within the period of three months, with the consequence that it would be reasonable for the industrial tribunal to extend the time. It seems to us, though the details will depend on the parties, their advisers and the tribunal, that the tribunal require to hear evidence from the solicitors about their normal practice and expectation in these matters and, in particular, evidence from the Post Office. It is not a question of what can be guaranteed of the postal services; it is a question of what a reasonable solicitor would have expected, or might reasonably have expected, at the time, date and place in question."
"We cannot however leave this case without saying that it seems to us an extremely dangerous practice for applicants to industrial tribunals to leave the posting of their applications until the penultimate day. In future cases, if this matter is gone into, it will be open to tribunals to hear evidence as to what now is the reasonable expectation as to delivery, even of first class mail, which is posted at a particular time and on a particular day. It seems to us that tribunals ought to go into the question as to what time the letter was posted, and to investigate in perhaps rather more depth than was done in the present case what was the expectation of the parties."
"We have emphasized in those cases yet again the importance of not leaving matters until the last minute and we expressed the view that in these days it was probably not reasonable to expect that the first-class post will necessarily arrive the following day. It is important to remember that where one has important documents such as writs or defences or applications for industrial tribunals or notes of appearance, there are time-limits involved and particular attention must be paid to those time-limits. Industrial Tribunals and this Court have always looked upon those time-limits as important for a number of reasons, which we need not repeat here today but the fact remains that in the future it seems to us unlikely that Industrial Tribunals will merely accept the evidence that the Post Office will say, as they will always say and probably believe, that in 99 per cent of the cases the first-class post arrives the next day."
"A finding of fact which is unsupported by any evidence clearly involves an error of law. The Tribunal cannot have directed itself, as it should, that findings of fact need some evidence to support them. The danger in the approach of May LJ is that an appellate court...."
"is that an appellate court can very easily persuade itself that, as it certainly would not have reached the same conclusion, the Tribunal that did so was `certainly wrong'. The more dogmatic the temperament of the judges, the more likely they are to take that view. That is a classic non sequitur. It does not matter whether, with whatever degree of certainty, the appellate court considers that it would have reached a different conclusion. What matters is whether the decision under appeal was a permissible option. To answer that question in the negative in the context of employment law the EAT will almost always have to be able to identify a finding of fact which was unsupported by any evidence or a clear self misdirection in law by the industrial tribunal. If it cannot do this it should re-examine with the greatest care its preliminary conclusion that the decision under appeal is not a permissible option and has to be characterised as perverse."
"Unsatisfactory though we found much of Mr McCrossan's evidence, this is not a case where he posted his originating application on the last possible day. On the face of it there was sufficient time between the 19th and the 22nd May for the document to arrive. We accept Mr McCrossan's evidence that he believed the letter would arrive in time and that he was not merely taking a chance. He held this belief because of the course of post with which he was familiar between Strabane and Birmingham which brought his mother's letters to him on the day after posting. It therefore seems to us, on the balance of probabilities, that the delay in presenting the originating application was outside Mr McCrossan's control."
