Judgment

KANIA, J. :- These two appeals are directed against the judgment of a Division Bench of the Gujarat High Court and arise on a certificate granted by the High Court under Art. 133(1)(a) of the Constitution as it stood prior to its amendment in 1972.

2. The facts necessary for & appreciation of the controversy before us are as follows :

The appellants in Civil Appeal No. 2310 of 1972 and the respondents in Civil Appeal No. 2311 of 1972 are a partnership firm and its partners. The respondent in Civil Appeal No. 2310 of 1972 and the appellant in Civil Appeal No. 2311 of 1972 is the Gujarat Electricity Board. A suit was instituted by the said partnership firm and its partners against the said Electricity Board in the Court of the Joint Civil Judge, Senior Division, Baroda, claiming certain amounts in respect of the work done under a construction contract and for certain extra items of work. We propose to refer to the parties by their description in the suit. Since the dispute in the appeals before us relates to only three items, we propose to refer to the facts which relate to those three items alone. The Trial Court passed a decree in favour of the plaintiffs and against the defendant for a sum of Rs. 1,33,956.25p. in respect of the claims of the plaintiffs for the amounts which allegedly remained payable to the plaintiffs. Out of these amounts, an amount of Rs. 1,00,522.28 was in respect of excavation of rock, two amounts of Rs. 13,930.10 each were for de-watering for cement concrete work at the bottom of the tank to be constructed and de-watering for masonry walls and a sum of Rs. 4,662.84 was given as the extra amount for transport of excavated soil. The defendant preferred an appeal against this decision to the High Court of Gujarat, being First Appeal No. 32 of 1964 and the plaintiffs filed their cross objections in the said appeal. The Division Bench of the Gujarat High Court, which disposed of the said appeal, reduced the amount to be paid to the plaintiffs for rock-cutting work to Rs. 62,740 and held that the remaining amounts set out earlier for de-watering and transport of excavated soil were not liable to be paid by the defendant to the plaintiffs. The appeal and the cross-objections were both allowed with proportionate costs.

3. Coming to the first item in respect of which there is a dispute, although Counsel argued at some length before us, the dispute is really in a narrow compass. One controversy was whether the item of rock-cutting is an item included in the contract and is liable to be paid for at the contract rates only, namely, Rs. 8 to Rs. 14 per hundred cubic feet in respect of excavation work at different levels as set out in para 14 of the judgment of the Division Bench. The, excavation referred to in the contract was of murram including hard murram. It is a common ground that there was no specific mention of excavation in rock or cutting of rock under the contract. The relevant term only spoke of "excavation for tank in any soil, murram, sock, etc." (emphasis supplied). The only dispute is whether the word "sock" was intended to mean "rock" as contended by the defendant. Both the Trial Court and the Division Bench of the Gujarat High Court have examined the evidence and come to the conclusion that the word "sock" could not refer to rock. We are in entire agreement with the reasoning of the High Court in this connection and hence we do not propose to discuss the evidence in this connection in our judgment. The main reason for coming to the above conclusion which appealed to the Gujarat High Court, and also appealed to us, is that it is well known that the charge for rock-cutting would be much higher than the charge for excavation of soil or murram as rock-cutting would involve more labour and heavier cost and no contractor would agree to the same rate for excavation of soil and for rock-cutting. Thus, this item cannot be regarded as item covered by the contract or to be paid for at the contract rate for
