"… 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. … 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."

"It is the alleged failure of Dwr Cymru to offer what Albion considers to be a reasonable common carriage price, and the Director's finding in the Decision that the common carriage price offered by Dwr Cymru did not constitute an abuse of a dominant position within the meaning of the Chapter II prohibition, which form the subject matter of this appeal."
"… It was plainly necessary for the Tribunal to have regard to the costs underlying the Bulk Supply Price, since the Director relied on the Bulk Supply Price as the basis for the ECPR calculation at paragraphs 329 and 338 of the Decision (see e.g. paragraphs 747 to 760 of the judgment of 6 October, and paragraph 288 of the judgment of 18 December). As it happens, the Bulk Supply Price has remained broadly the same (around 26p/m3) up to the present day. However, that does not imply that the Tribunal has taken any position, in its judgments or otherwise, in relation to what the level of any contemporaneous or future Bulk Supply Price should be ."
