“Our Courts have consistently acted on the view that it is their function in the ordinary run of contentious litigation to decide only live, practical questions, and that they have no concern with hypothetical, premature or academic questions, nor do they exist to advise litigants as to the policy which they should adopt in the ordering of their affairs. The Courts are neither a debating club nor an advisory bureau. Just what is a live practical question is not always easy to decide and must, in the long run, turn on the circumstances of the particular case.”
“The discretion to hear disputes, even in the area of public law, must, however, be exercised with caution and appeals which are academic between the parties should not be heard unless there is a good reason in the public interest for doing so, as for example (but only by way of example) when a discrete point of statutory construction arises which does not involve detailed consideration of facts and where a large number of similar cases exist or are anticipated so that the issue will most likely need to be resolved in the near future.”
