“13..........In such a situation it appears to us that the real intention of the Legislature was not to equate the expression “interlocutory order” as invariably being converse of the words “final order”. There may be an order passed during the course of a proceeding which may not be final in the sense noticed in Kuppuswami case , but, yet it may not be an interlocutory order — pure or simple. Some kinds of order may fall in between the two. By a rule of harmonious construction, we think that the bar in sub-section (2) of Section 397 is not meant to be attracted to such kinds of intermediate orders. They may not be final orders for the purposes of Article 134 of the Constitution, yet it would not be correct to characterise them as merely interlocutory orders within the meaning of Section 397(2). It is neither advisable, nor possible, to make a catalogue of orders to demonstrate which kinds of orders would be merely, purely or simply interlocutory and which kinds of orders would be final, and then to prepare an exhaustive list of those types of orders which will fall in between the two. The first two kinds are wellknown and can be culled out from many decided cases. We may, however, indicate that the type of order with which we are concerned in this case, even though it may not be final in one sense, is surely not interlocutory so as to attract the bar of sub-section (2) of Section 397. In our opinion it must be taken to be an order of the type falling in the middle course.”
