“The judge took what has turned out to be an unfortunate course. Instead of finding the facts, which should have presented no difficulty and taken little time, he allowed a preliminary point 5 of law to be taken. … So the case has reached this House on hypothetical facts, the correctness of which remain to be tried. I, with others of your Lordships, have often protested against the practice of allowing preliminary points to be taken, since this course frequently adds to the 10 difficulties of courts of appeal and tends to increase the cost and time of legal proceedings. If this practice cannot be confined to cases where the facts are complicated and the legal issue short and easily decided, cases outside this guiding principle should at least be exceptional.”
“In my judgment, the right approach to preliminary issues should be as 30 follows. (a) Only issues which are decisive or potentially decisive should be identified. (b) The questions should usually be questions of law. (c) They should be decided on the basis of a schedule of agreed or assumed facts. (d) They should be triable without significant delay, making full allowance for the implications of a possible appeal. (e) 35 Any order should be made by the court following a case management conference.”
“A number of recent appeals from decisions of the Fair 20 Employment/Industrial tribunals have involved challenges to conclusions reached on preliminary points - see, for instance, Bombadier Aerospace v McConnell and Cunningham v Ballylaw Foods. While I do not suggest that the hearing of a preliminary issue will never be 25 appropriate for determination by a tribunal, I consider that the power to determine a preliminary point should be sparingly exercised. It is, I believe, often difficult to segregate in a wholly compartmentalised way a single issue in this field from other material that may have 30 relevance to the matter to be decided.”
