Why it matters
The words substantial question of law control the gateway to a higher appeal. Where the decree appealed from affirms the decision of the court immediately below, no certificate can issue unless the appeal involves such a question. Everything therefore turns on what the adjective "substantial" is doing in that phrase, and this Full Bench is the decision that settles it.
Its value for an examinee is that it does two jobs at once. It clears away a wrong test — that any question of law which happens to affect the rights of the parties in a material way is ipso facto substantial — and it then supplies a workable positive test in a single sentence which can be reproduced verbatim.
How the question came to a Full Bench
The matter began as an application for leave to appeal. Before disposing of it finally, the Division Bench thought it necessary to obtain an authoritative decision by a Full Bench on the meaning of the words "substantial question of law" occurring in Article 133.
The reason was an earlier Division Bench decision, Mahadeva Royal v Chikka Royal, where the learned Judges had granted a certificate on a question about the admissibility of certain documents even while saying there was no substance in the contention advanced. The referring Judges disagreed with that approach. They pointed out where it leads: suppose a question of limitation is raised which has already been disposed of one way by the Judicial Committee, the Supreme Court or a Full Bench, the High Court would still be bound to give leave merely because the point affected the parties substantially.
The referring order states the correction in a sentence worth memorising: the word "substantial" qualifies the expression "question of law" and not "the subject-matter of the appeal". And it adds the positive formulation which the Full Bench later adopted and widened: "Unless a question of law is one of importance and difficulty or in regard to which there is a reasonable doubt or difference of opinion, it cannot be a substantial question of law within the meaning of the Article."
The question referred was, in substance, whether the phrase means an important or difficult question of law, or any question of law affecting the rights of parties.
The statutory history
Rajamannar C.J. begins by tracing the requirement. The condition in Article 133 is the identical condition imposed for an appeal to the Judicial Committee under s. 110 of the Code. It was introduced for the first time by the Privy Council Appeals Act of 1874, appeared in the Code of 1877, was reproduced in the Code of 1882 and again in s. 110 of the Code of 1908, the only change being the addition of the words "or final order" after "the decree".
Two points were settled early. The substantial question of law need not be restricted to questions arising on the facts found concurrently by the courts below. And it is not enough, on an application for leave, that the grounds of appeal disclose a question of law: the court must also find that there really is a substantial question of law raised.
The meaning of "substantial"
The Court notes that the word carries two distinct shades of meaning. In legal parlance it is often understood as "essential, material"; in ordinary usage it means "having substance; real worth". In ss. 10 and 11 of the Code the cognate adverb is used in the first sense.
The Privy Council authority is then placed. In Raghunath Prasad Singh v Deputy Commissioner of Partabgarh their Lordships ruled that a substantial question of law did not mean a question of general importance but "a substantial question of law as between the parties in the case involved", and that reading was confirmed in Guran Ditta v Ram Ditta. So a question of general importance is not required; it is sufficient if the question arises between the parties.
But — and this is the pivot of the judgment — that does not mean every question of law between the parties is substantial. In the Privy Council's own paraphrase the word "substantial" recurs alongside the phrase "as between the parties". The tempting shortcut, that a question is substantial whenever its decision materially affects the rights of the parties and not merely incidentally, is rejected in terms: logically that test would make even a palpably absurd plea raise a substantial question of law, simply because the decision on the merits would be directly affected by it. Mahadeva Royal is accordingly held not to be authority for that position.
The positive test
The Court then states the principles. When a question of law is fairly arguable, when there is room for difference of opinion on it, then such a question would be a substantial question of law. Where the High Court found it necessary to deal with a point at some length and to discuss alternative views on it, that too points towards substantiality. Conversely, when a point of law is practically covered by a decision of the highest authority, it would not be a substantial question; and if the general principles are well settled, a mere application of such principles would not involve a substantial question of law. Where a conflict of judicial opinion among the High Courts exists and there is no direct decision of the highest Court, that divergence is treated as conclusive evidence of the existence of a substantial question of law.
Held
The answer returned to the referring Bench was this: "The only answer to the question that we can usefully give is that any question of law affecting the rights of parties would not by itself be a substantial question of law. An important or difficult question would of course be a substantial question; but even if a question is not important or difficult, if there is room for reasonable doubt or difference of opinion on the question, then it would be a substantial question of law within the meaning of Article 133, Constitution of India."
Applying that answer, the Division Bench dismissed the application with costs. The construction of the trust deed had raised no reasonable doubt; the fact that the Court had dealt with it at some length, only to meet the arguments advanced, did not make the question important or difficult. The res judicata point pressed as a second substantial question had no merits either.
