"Within such further period as the Tribunal considers reasonable in a case it is satisfied that it was not reasonably practicable for the complaint to be presented before the end of the specified period of three-months."
"Where the Tribunal is satisfied that it was not reasonably practicable for the complaint to be presented before the end of the period of three months." has been the subject of a certain amount of judicial authority. The written submissions of the respondents, which we have taken into account in this case, refer us in particular to an earlier decision of another division of this court, presided over by Slynn J as he then was, in Beanstalk Shelving Ltd v Horn[1980] ICR 273 . That was a case in which a Tribunal had accepted that an applicant, who had relied on delivery by the first class post taking place on the following day, had taken steps which were reasonable and was not prevented from having his application considered by the consideration that it might have been practicable in some way to post the application earlier, allowing more time. As Slynn J explained in that case, the expression "reasonably practicable" has been given a somewhat extended meaning in this particular context, as he says on page 275 D: "
"Accordingly, on the basis of these authorities, the question is whether, if a letter is posted by first class post, on a particular day, it can be expected, in the ordinary course of post to arrive within the time limit for making an application. Here the Industrial Tribunal were confident that it could have been expected in the ordinary course of post, having been sent first class, to have arrived on the following day. The Tribunal would not appear, it would seem, from the notes of evidence, to have had a great deal of evidence as to the position; but it is clear they were told it was sent first class; and they were referred to what is said in notes to the Supreme Court Practice [1979] that if a letter is sent by first class mail at that time, service will be treated as if having been effected on the next day after posting."
