“(1) Subject to the provisions of the 2007 Act and any other enactment, the Tribunal may regulate its own procedure. (2) The Tribunal may give a direction in relation to the conduct or disposal of proceedings at any time, including a direction amending, suspending or setting aside an earlier direction. (3) In particular, and without restricting the general powers in paragraphs (1) and (2), the Tribunal may by direction … (e) deal with an issue in the proceedings as a preliminary issue …”
“Preliminary issues have received widely varying judicial comments through the years. In Tilling v Whiteman[1980] AC 1 Lord Scarman described preliminary issues as often being ‘treacherous shortcuts’ which can lead to ‘delay, anxiety and expense’. On the other hand, it is clear that determination of preliminary issues can be very beneficial asCPR Part 24 recognises. To my mind, as is so often the case, there are inevitably conflicting factors. The determination of a preliminary issue can be a very satisfactory way of cheaply and quickly disposing of a case or part of a case. However, as this case and Tilling v Whiteman show, careful thought should be given to the possible consequences, benefits and disadvantages of having a preliminary issue before that course is adopted.”
“In my judgment, the right approach to preliminary issues should be as 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. Any order should be made by the court following a case management conference.”
‘A number of recent appeals from decisions of the Fair 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 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 relevance to the matter to be decided.’
“In my judgment, the ordering of a preliminary issue is bound to include advantages and disadvantages, or pros and cons, some of which are predictable and some of which are less predictable. As I see it, the task of the court in being asked to order a preliminary issue in a case such as this, is to weigh up the possible pros and cons of ordering or not ordering a preliminary issue and decide where the balance lies. When I put this, or something like it, to counsel, neither of them demurred.”
