[W]e decided to hear counsel on both sides on the point, even though it was a point which could have been properly raised under a respondents’ notice. This course is of course permitted by the Rules (see, for example, Order 8 rule 3(6) of the Supreme Court Rules, 1985). Besides, our consideration of the point is necessary for the determination of the real question in controversy in the appeal within the meaning of Section 22 of the Supreme Court Act. Indeed it is envisaged by the subsidiary issue framed for the appellants in their brief. But let me emphasize that although such powers, no doubt, exist, they are such that this court does not want to make a habit of drawing therefrom constantly so that it does not give the wrong impression that it is taking sides in matters in controversy before it. A respondent’s counsel should always make his own decision and file a respondent’s notice whenever necessary, otherwise he may find that he cannot advance a certain line of argument. I am invoking the power in this case because it is necessary for my decision in the case and has been raised by the subsidiary issue and was fully argued.
