The phrase ”substantial question of law”, as occurring in the amended Section 100 cpc is not defined in the Code. The word substantial, as qualifying ”question of law”, means of having substance, essential, real, of sound worth, important or considerable. It is to be understood as something in contradistinction with- technical, of no substance or consequence, or academic merely. However, it is clear that the legislature has chosen not to qualify the scope of “substantial question of law” by suffixing the words ”of general importance” as has been done in many other provisions such as Section 109 of the Code or Article 133(1)(a) of the Constitution.
The substantial question of law on which a second appeal shall be heard need not necessarily be a substantial question of law of general importance. In Guran Ditta v. Ram Ditta [(1927-28) 5I5 IA 235 : AIR 1928 PC 172] the phrase substantial question of law as it was employed in the last clause of the then existing Section 100 CPC (since omitted by the Amendment Act, 1973) came up for consideration and their Lordships held that it did not mean a substantial question of general importance but a substantial question of law which was involved in the case. In Sir Chunilal case [1962 Supp (3) SCR 549 : AIR 1962 SC 1314] the Constitution Bench expressed agreement with the following view taken by a Full Bench of the Madras High Court in Rimmalapudi Subba Rao v. Noony Veeraju [AIR 1951 Mad 969 : (1951) 2 MLJ 222 (FB)] : (Sir Chunilal case [1962 Supp (3) SCR 549 : AIR 1962 SC 1314] , SCR p. 557) “When a question of law is fairly arguable, where there is room for difference of opinion on it or where the Court thought it necessary to deal with that question at some length and discuss alternative views, then the question would be a substantial question of law. On the other hand if the question was practically covered by the decision of the highest court or if the general principles to be applied in determining the question are well settled and the only question was of applying those principles to the particular fact of the case it would not be a substantial question of law.”
