It is the unnecessary nature of the Tribunal's legal rulings in its judgment that is most troubling. The court itself drew the attention of the parties at the hearing to R (Burke) v GMC [2006] QB 27. There are sound reasons why courts and tribunals at all levels generally confine themselves to deciding what is necessary for the adjudication of the actual disputes between the parties. Deciding no more than is necessary may be described as an unimaginative, unadventurous, inactive, conservative or restrictive approach to the judicial function, but the lessons of practical experience are that unnecessary opinions and findings of courts are fraught with danger.
Specialist tribunals seem to be more prone than ordinary courts to yield to the temptation of generous general advice and guidance. The wish to be helpful to users is understandable. It may even be commendable. But bodies established to adjudicate on disputes are not in the business of giving advisory opinions to litigants or potential litigants. They should take care not to be, or to feel, pressured by the parties or by interveners or by critics to do things which they are not intended, qualified or equipped to do. In general, more harm than good is likely to be done by deciding more than is necessary for the adjudication of the actual dispute.
One of the dangers of unnecessary rulings is that, with only the assistance of the parties and without the benefit of wider consultation on relevant aspects of the public interest, the court's opinions, though meant to be helpful, may turn out to be damaging in practice and wrong in law. The court may be unaware of all the available arguments or ignorant of the practical implications of what it says. Those who rely on its advisory opinions when applying the law in practice may be misled or confused. A judgment aimed at giving authoritative advice and guidance may be misused by selective citation in different and unforeseen disputes and circumstances.
It is also the case that the Court of Appeal is faced with a dilemma when presented with unnecessarily wide ranging judgments at first instance or, as in this case, at a lower appellate level. If, on the one hand, the Court of Appeal accepts an appeal against unnecessary rulings on points of law, it risks making the situation even worse by itself expressing unnecessary opinions, apparently impressed with greater authority. If, on the other hand, it takes a purist stance and refuses to accept the appeal at all, those who have reasonable grounds to be aggrieved by parts of the judgment of the lower court may have to wait a very long time in the happenstance of litigation before they have an opportunity to challenge those parts of the judgment. Indeed, they may never have the chance to get what has been said judicially examined and, if necessary, corrected.
