"We conclude that the Originating Application was actually delivered to the Central Office in the course of the post by the Post Office on Monday the5 October 1992 because of the stamp on it on that date. We have to consider whether it was the reasonable expectation of the applicant's Solicitors that the application would be delivered in the ordinary course on Saturday the3 October 1992 . We have their assertion in their letter that they did have that expectation and accept that. All members of the Tribunal have known recent public announcements by the Post Office that they deliver 90% of their first-class mail within 24 hours of its posting. We have come to the conclusion that we are entitled to take that into account in deciding this case."
