My question concerns the principle that constitutional courts should not decide what is not strictly necessary for deciding the case at hand. What happens if, say the Supreme Court, made well reasoned and detailed (but unduly far-reaching) conclusions about a legal question deciding which was not at all necessary for the case at hand ?
Do these circumstances alone suffice to argue that these conclusions (insofar as they relate to the question which was not before the court) do not form binding precedents when the legal question arises before a High Court in a future case? I am attaching a pic from the book Constitutional Law of India Vol-II by H.M. Seervai.
This question is in context of India, but I would appreciate answers from other jurisdictions as well.
