Explanation:

Section 100 says that a second appeal shall lie if in the opinion of the High Court it involves, a substantial question of law. Existence of substantial question of law is the requisite of a second appeal. Moreover no second appeal lies from an order but it lies only from a decree.. The word substantial as qualifying questions of law means - of having substance, essential, real, of sound worth, important, 'or considerable. However the legislature ' has chosen not to qualify the scope substantial law by suffixing' the' words of general importance as has been done in many other pro visions.
