JAGANNATHA SHETTY, J. ( 1 ) THIS appeal concerns with the right of the appellant to have his claim referred to arbitration for adjudication. The I Addl. Civil Judge, Civil Station, bangalore who tried the ma,tter as O. S. No. 173 of 1977, dismissed the appellant's application filed under S. 20 of the Arbitration Act. This appeal is preferred against that order. ( 2 ) THE parties rested their case only on their pleadings and the terms of the agreement. They did not produce any oral evidence. ( 3 ) WE will give a brief summary of the facts avoiding as far as possible the controversial matters. The appellant was a railway contractor. He entered into an agreement with the respondents for execution of certain works including the work of "doubling of track between Renigunta and Balapalleearth work forming bank and cutting etc. " earmarked between chainage 0 and 10,600 Reach-I. As per the terms of the agreement, the respondents were to point out the lands and places where work had to be carried out and supplies were required to be made. The respondents were further required to give the details of the materials required with the specifications and the quantities. They were also required to give the drawings of the works to be executed. It was only thereafter the appellant was required to commence the works entrusted to him. The respondents did not attend to those preliminary requirements. in time, and there was considerable delay on their part in performing their obligations. Consequently, the appellant had to wait for his turn to commence the execution of the works. ( 4 ) THE period prescribed under the agreement for completion of the works was, however, extended, and the appellant completed all the prescribed works on June 27, 1975. On July 1, 1975, he made a claim for additional payments at higher rates on various items of works executed by him. On September 10, 1975, he restricted the additional claim to Rs. four lakhs and odd. He did not, however, pursue that claim. He had a second thought over the matter. On October 31, 1975, he wrote a short letter informing the respondents that in order to develop good relationship with the administration, he was withdrawing the said additional claim. ( 5 ) ON November 14, 1975, the respondents paid the final bill at the rates agreed upon in the agreement. He had a second thought over the matter. On October 31, 1975, he wrote a short letter informing the respondents that in order to develop good relationship with the administration, he was withdrawing the said additional claim. ( 5 ) ON November 14, 1975, the respondents paid the final bill at the rates agreed upon in the agreement. They also refunded the security deposit. The appellant, notwithstanding his desire to maintain the good relationship with the administration, could not perhaps, resist the temptation to claim something more. On May 24, 1977, he asked the respondents to pay him 5. 7 lakhs as compensation for the loss suf- ferred by him due to the delay in performing the contractual obligations by the respondents. But the respondents did not even reply to that notice. The appellant then called upon the respondents to refer the said claim to arbitration under clause 63 (1) of the general conditions of the agreement. The respondents, as usual, turned down that demand. So, the appellant moved the court below with an application under S. 20 of the Arbitration Act for a reference to arbitration. The respondent opposed that application. ( 6 ) UPON the rival contentions raised in the pleadings, the lower court framed the following issues for consideration: 1. Whether the plaintiff has made out a case for making a reference to the arbitrators as per the provisions of the indian Arbitration Act? 2. If so' whether the plaintiff is entitled to the said reference? on the first question, the Court held that the dispute arising out of the appellant's claim falls within the said arbitration clause. But while coming to the second question, it declined to make a reference. The Court held that the appellant was estopped from raising the dispute since' he had earlier made such a claim and unconditionally withdrew it. The Court based its conclusion solely on the appellant's letter dated October 31, 1975. ( 7 ) IN this appeal, there was no argument before us with regard to the legality of the finding recorded by the lower court on the first question. We therefore proceed on the basis that the dispute raised by the appellant falls squarely within the arbitration clause in the agreement between the parties. ( 7 ) IN this appeal, there was no argument before us with regard to the legality of the finding recorded by the lower court on the first question. We therefore proceed on the basis that the dispute raised by the appellant falls squarely within the arbitration clause in the agreement between the parties. The only point that we have to decide is whether the appellant in the context and in the situation, was estopped from raising the dispute and demanding a reference to arbitration. ( 8 ) THE decision on this point turns mainly on the appellant's letter dated october 31, 1975 (Annexure 57) which, for immediate reference, is set out hereunder:"sir, name of work: Doubling of track between Renigunta and Balapalle - Earth - work in forming Bank and cutting etc. and supply of materials for the construction of bridges, service roads etc. between Ch. O. Metre and Ch. 10. 600 Metres - Reach I agreement No. 107 CL BNC 73 of 20-10-73. After consideration of my claims and to develop good relationship with the Administration, I hereby withdraw the conditions which I have raised in my letter dated 10-9-75 addressed to XEN and 1-7-75 to gm|cn|bnc. Thanking you, yours faithfully, sd/- signature of the Contractor. P. A. H. of Y . S. C. Korma Reddy. "it may be recalled from the prenatal history of the case that the appellant first wanted an additional payment of Rs. four lakhs and odd to make good the alleged loss suffered due to the escalation of the costs of construction. He made that claim, no doubt, but thought fit later to withdraw it for the purpose of what he described as 'to develop good relationship with the administration'. It was his unilateral action with no problem to others. The short question is whether the withdrawal of that claim precluded the appellant from demanding more payment for the works executed by him and asking for its adjudication by arbitration. ( 9 ) MR. Krishnamurthy, Senior advocate for the appellant in his characteristic style of submission marked with precision and grasp, urged that on the material on record, we must put out of the way both the doctrines of estoppel and waiver. According to him, these doctrines with different considerations have no part to play on the right of the appellant to seek a reference under the arbitration clause. According to him, these doctrines with different considerations have no part to play on the right of the appellant to seek a reference under the arbitration clause. On the other hand, learned Advocate General who appeared for the respondents sought to justify the order under appeal not only on the question of estoppel, but also on the principle of "accord and satisfaction" by which the contract between the parties was fully and finally discharged thereby putting an end to the arbitration clause thereunder. He urged that the appellant after withdrawing his claim by his letter dated October, 31 1975, received the full payment under the final bill without any reservation of his further or future claim. He also said that that payment would not have been made and security Deposits would not have been refunded but for the said letter which under the circumstances, amounted to and was treated as 'no claim Certificate'. ( 10 ) WE may first clear the ground on-the last contention urged by learned advocate General. If, as contended by him that the appellant had given a 'no Claim Certificate', then the matter ends there. Certainly he was not entitled to claim further payment in view of clause 43 (2) of the agreement, which provides:"the Contractor shall not be entitled to make any claim whatsoever against the Railway under or by virtue of or arising out of this contract, nor shall the Railway entertain or consider any such claim, if made by the Contractor, after he shall have signed a 'no Claim' certificate in favour of the Railway, in such form as shall be required by the Railway, after the works are finally measured up. ""no Claim Certificate" has to be given in favour of the respondents in the required form as stated above. But we do not find any such certificate insisted upon by the respondents or given by the appellant. The appellant by his letter dated October 31, 1975 did not just press the claim then made for extra payment. Neither on fact nor under law 'that letter could' be construed as a 'no Claim Certificate'. After the said' letter, the respondents paid the final bill. Even while receiving that payment, the appellant has not committed himself not to claim anything more. The respondents, in our opinion, therefore, have misconstrued the contents of the said letter. Neither on fact nor under law 'that letter could' be construed as a 'no Claim Certificate'. After the said' letter, the respondents paid the final bill. Even while receiving that payment, the appellant has not committed himself not to claim anything more. The respondents, in our opinion, therefore, have misconstrued the contents of the said letter. ( 11 ) WE also do not find any substance in the contention that the said letter operated as estoppel or waiver against the appellant. The doctrine of estoppel is embodied in S. 115 of the evidence Act. To call into aid that doctrine; three conditions must necessarily be satisfied as observed by the Supreme Court in Gyarsi Bai v. Dhansukh Lal (1 ). They are: 1. Representation by a person to another; 2. The other shall have acted upon the said representation; and 3. Such action shall have been detrimental to the interests of the person to whom the representation has been made. In the instant case, although it may be said that the first condition was satisfied, it can never be stated that the second and third conditions were satisfied. The respondents did not in any manner act on the representation of the appellant and that too to the detriment to their interests. It was, however, urged that the respondents would not have paid the final bill but for the withdrawal of the additional claim by the appellant. We may point out that the final bill was prepared on the basis of the final measurements of the works actually executed by the appellant. He was legitimately entitled to that payment. The respondents by making that payment, had only discharged their contractual liability and did not act in any manner prejudicial to their interests. It may be stated tha,t the claim under dispute has nothing to do with the final bill or the final measurements recorded thereunder. The appellant claims additional payment by way of damages or compensation for the loss said to have been suffered by him due to the delay in the performance of the obligations cast on the respondents under the agreement. This claim is independent of and in addition to the final bill. He cannot, therefore, be shut out either by estoppel or by waiver. The terms "estoppel" and 'waiver' are sometimes used interchangeably, but the two are quite distinct and different. This claim is independent of and in addition to the final bill. He cannot, therefore, be shut out either by estoppel or by waiver. The terms "estoppel" and 'waiver' are sometimes used interchangeably, but the two are quite distinct and different. Estoppel is a rule of evidence and is not a cause of action. On the other hand, waiver is contractual and may constitute a cause of action. In Halsbury's Laws of England, 3rd edn. Vol. 14, page 637, it is stated:"waiver is the abandonment of a right, and is either express or implied from conduct. Where the right is a right of action or an interest in property, an express waiver depends upon the same considerations as a release. If it is a mere statement of an intention not to insist upon the right, it is not effectual unless made with consideration. "the waiver is thus a voluntary and intentional abandonment or relinquishment of a known right. It must be supported by a valid consideration unless it arises from conduct creating an estoppel. There is at any rate, no such thing as estoppel by waiver as observed by the Privy Council. (See Dawsons bank, Ltd. v. Nippon Menkwa Kabushihi Kaish (Japan Cotton Trading co. , Ltd (2 ). In the instant case, the appellant has a legal remedy to have his claim adjudicated by arbitration. He did not then ask for a reference to adjudication before unilaterally withdrawing his first claim. He did not withdraw that claim for any consideration. He is now demanding a reference and cannot, therefore, be denied of the same on the ground that he had waived his right by withdrawing his claim by the aforesaid letter. ( 12 ) THE question next to be considered is, whether the accord and satisfaction by payment of the final bill has put an end to the agreement and the arbitration clause thereunder? there cannot be any controversy on this point too and may, therefore, be easily disposed of. The accord and satisfaction has always been understood as a method of discharge of a contract and may be a good defence to an action for breach of a contract, but it will have no effect to put an end to the contract itself. Sarkar, J. while examining this aspect, observed in Union of India v. Kishorilal Gupta and Bros. (3 ). Sarkar, J. while examining this aspect, observed in Union of India v. Kishorilal Gupta and Bros. (3 ). "the effect of an accord and satisfaction is therefore to secure a release from an obligation arising under a contract. Now it is difficult to conceive of an obligation arising from a contract unless the contract existed. An accord and satisfaction which secures a release from such an obligation is really based on the existence of the contract instead of treating it as non-existent. The contract is not annihilated but the obligations under it cease to be enforceable. Therefore it is that when an action is brought for the appropriate remedy for non-per- mance of these obligations that an accord and satisfaction furnishes a good defence. The defence is not that the contract has come to an end but that its breach has been satisfied by accord and satisfaction. "in Damodar Valley Corporation v. K. K. Kar, (4), the Supreme Court observed:"similarly the question whether there has been a settlement of all the claims arising in connection with the contract also postulates the existence of the contract. The principle laid down by Sarkar, J. in kishorilal Gupta Bros's case (2) that accord and satisfaction does not put an end to the arbitration clause was not dissented from by the majority. On the other hana proposition (6) seems to lend weight to the views of Sarkar, J. " ( 13 ) IT is, however, open for the respondents to urge before the arbitrator that in view of the accord and satisfaction reached in the case and the settlement of all the alleged claims, the appellant has no right to raise thp dispute and ask for its adjudication. If such a contention is raised, it would be proper for the arbitrator to decide that question before going into the merits of the disputed claim. A Full bench decision of this Court in M. S. Ramiah v. State of Karnataka (5) to which one of us (K. Jagannatha Shetty, J.) was a party, has taken a similar view. It was observed. "in concervable cases, even the existence or non-existence of a dispute might itself assume the character of a dispute for adjudication by the arbitrators. The arbitrators are also competent to decide whether that dispute is excluded from the arbitration clause. It was observed. "in concervable cases, even the existence or non-existence of a dispute might itself assume the character of a dispute for adjudication by the arbitrators. The arbitrators are also competent to decide whether that dispute is excluded from the arbitration clause. 'an arbitration agreement may explicitly empower the arbitrator to decide whether or not a particular dispute is within the arbitration agreement. ' (See Hudson's Building and Engineering contracts,. Ninth Edition, page 658 ). But even if there is no such express power unless the dispute is expressly excluded from the arbitration clause "an arbitrator is always entitled to enquire whether or not he has jurisdiction. " (See Russel on arbitration, 18th Edition, page 73 ). "it is, therefore, open to the Arbitrator to decide the question, if raised, whether there has been a settlement of all the claims arising in connection with the contract having regard to. the effect of the accord and satisfaction. ( 14 ) BEFORE parting with this case, we must make it clear that we shall not be understood to have expressed any opinion on the merits of the disputed claim. It would be for the arbitrator to adjudicate in accordance with law and in the light of the observations made. ( 15 ) IN the result, the appeal is allowed; reversing the order of the lower court, the matter stands remitted to the City ' Civil Court, bangalore with a direction to restore the suit on file and refer the dispute to arbitration after hearing the parties. --- *** --- .
