Summarize the following court judgment. Appeal No. 135 of 1972. Appeal by Special Leave from the Judgment and Order dated 12 8 71 of the Delhi High Court in F.A.O. No. 47 D of 1964. Gobind Das and Girish Chandra	 for the Appellant. Bakshi Shiv Charan Singh and Harbans Singh	 for the Respondents. The Judgment of the Court was delivered by BHAGWATI	 J. 	 This appeal	 by special leave	 is direct ed against a judgment of the High Court of Delhi setting aside an award made by an arbitrator on the ground that he was not a validly appointed arbitrator and hence had no jurisdiction to arbitrate and make an award. The facts giving rise to the appeal are few and may be briefly stated as follows. The respondents a partnership firm entered into a contract with the appellant for the supply of 30	000 tons of East German sugar at the rate and as the terms and condi tions set out in a letter dated 3rd July	 1954 addressed by the Secretary to the Government of India	 in the Ministry of Food & Agriculture to the respondents. The Ministry of Food and Agriculture was concerned with the subject matter of this contract and hence clause (9) provided that "superin tendence and inspection of quality	 weight and packing of sugar Shall be made by a reputable superintending agency to be approved by the Government of India	 in the Ministry of Food & Agriculture" and clause (10) stipulated for delivery to be made to "authorities or parties nominated by the Ministry of Food and Agriculture". There was provision for arbitration made in clause (17) and that clause also re ferred to the Ministry of Food and Agriculture. It was in the following terms: "ARBITRATION: All questions	 disputes or differences whatsoever which may at any time arise between the parties to the agreement touching the agreement or the subject matter thereof	 arising out of or in relation thereto and whether as to construction or otherwise shall be referred to a single arbitrator for decision. Such a single arbitrator shall be nominated by the Secretary to the Government of India in the Ministry of Food and Agriculture in his absolute discretion and the decision of such arbitrator shall be final and binding upon the parties. The reference to the arbitrator shall be governed by the provisions of the Indian as amended from time to time and the rules made thereunder. " It appears that disputes arose between the appellant and. the respondents in regard to the fulfilment of this con tract. The appellant made a claim for payment of Rs. 3	29	107 8 0 against the respondents by a letter dated 11th August	 1956 and threatened to recover it from the security furnished by the respondents through their bankers. The respondents disputed the claim of the appellant and by their letter dated 23rd August	 1956 pointed out that it was not competent to the: appellant to recover the amount of the demand from the bankers of the 485 respondents without first. establishing its claim by arbi tration or suit. The respondents intimated to the appellant that they were prepared to go to arbitration and. suggested that it would be better still	 .if a special case for the opinion of the court were stated under section 90 of the Code of Civil Procedure. The respondents also claimed to recover from the appellant under the contract diverse amounts aggregating to Rs. 6	05	689. There was no response to this letter from the appellant and no steps were taken by the appellant to have the disputes referred to an arbitrator nominated by the Secretary in the Ministry of Food and Agriculture as provided in clause (17) of the Contract. In the meantime	 as a result of an order made by the President under clause (3) of Article 77 of the Constitution	 the Ministry of Food and Agriculture was bifurcated into two separate Ministries	 one of Food and the other of Agricul ture	 with effect from 19th October	 1956 and sugar	 the subject matter of the contract	 came to be allotted to the Ministry of Food. The respondents	 by their letter dated 9th November	 1956	 pointed out to the Secretary	 Ministry of Food that by reason of this bifurcation	 the Ministry of Food and Agriculture has ceased to exist and there was no Secretary in the Ministry of Food and Agriculture and the arbitration agreement contained in clause (17) of the con tract had	 therefore	 become a dead letter and was no longer enforceable and once again called upon the appellant to agree in stating a special case for the opinion of the court failing which the respondents would have to file a suit against the appellant. This letter also did not evoke any response from the appellant and the disputes remained unre solved. On 13th/l4th February	 1956 the appellant addressed a letter to the respondents stating that since the Ministry of Food and Agriculture was bifurcated into Ministry of Food and Ministry of Agriculture	 it was necessary to amend clause (17) of the Contract so as to provide for arbitration by "the Secretary to the Ministry	 Government of India administratively dealing with the subject of contract at the time of reference to arbitration	 or if there is no Secre tary	 the administrative head of such Ministry at the time of such reference" and proposed an amendment to that effect for the acceptance of the respondents. The respondents	 by their letter in reply dated 26th February	 1957	 declined to accept the proposal for amendment of clause (17) of the contract and once again reiterated that the arbitration agreement contained in that clause was "dead and unenforce able". However	 within a short time thereafter	 another order was issued by the President under clause (3) of Arti cle 77 of the Constitution integrating the Ministry of Food and the Ministry of Agriculture into one single Ministry of Food and Agriculture with effect from 23rd April	 1957. This Ministry of Food and Agriculture had two departments	 one of Food and the other of Agriculture	 and there was a Secretary incharge each department. It seems that the appellant requested the Secretary	 Department of Food in the Ministry of Food and Agriculture to nominate an arbitration for adjudicating upon the disputes which had arisen between the appellant and the respondents in terms of clause (17) the Contract and the Secretary	 Department of Food in the Ministry of Food and Agriculture	 by a letter dated 27th February	 1958	 nominated Shri A.V. Vishwanath Shastri	 Advocate	 to act as sole arbitrator to 486 adjudicate upon such disputes. On the same day	 the re spondents served a notice on the appellant under section 80 of the Code of Civil Procedure demanding payment of the amounts due to the respondents and stating that in case the appellant failed to meet these demands	 the respondents would have to file a suit against the appellant. Though respondents gave this notice under section 80 of the Code of Civil Procedure	 they did not proceed to file a suit	 but instead filed their statement of claim before the arbitrator and in the statement they claimed payment of an aggregate sum of Rs. 7	89	858/ from the appellant and also prayed for a declaration that the contract stood "final and properly performed" by the respondents. The appellant filed its reply disputing the claim of the respondents. The appellant also field a statement making its own claim for Rs. 3	29	107 8 0 against the respondents. It was stated in paragraph 18 of the statement of claim of the appellant "that under Clause 17 of the contract the Secretary Food and Agriculture Ministry of the Government in his discretion has the right to nominate a sole Arbitrator and refer the dis pute to the Arbitrator and that has been duly done on 27th February	1958	 and the parties have been duly notified under Secretary to the Government letter No. SIMP 3(4C) dated the 27th February	 1958". The respondents filed their written statement denying the claim of the appellant and in para graph 18 of this written statement they averted "That para 18 of the Statement of Claim of the Government of India is not objected to". The proceedings in connection with the claim of the respondents and the counter claim of the appel lant were carried on before the arbitrator and the respond ents participated in the arbitration proceedings without objection or protest against the jurisdiction of the arbi trator. The arbitrator ultimately made an award against the respondents. The appellant made an application before the Sub Judge	 Delhi to pass a decree in terms of the award. The respond ents resisted the application of the appellant and sought to set aside the award mainly on two grounds. One ground was that Daljeet Singh	 a partner of the respondents	 had no power to bind the other partners by an arbitration agreement and hence clause (17) of the contract was not binding on the respondents	 and the other was that the arbitrator was not validly appointed and he had	 therefore	 no jurisdiction to enter upon the reference and adjudicate upon the disputes between the parties. Both these grounds were rejected by the learned Sub Judge and the award was made a rule of the court. The respondents thereupon preferred an appeal to the High Court. The same two grounds were also urged in the appeal. Out of them	 the first ground relating to lack of authority in Daljeet Singh to bind the respondents by clause (17) of the contract Was negatived by the High Court and it was held that clause being an integral part of the contract	 the authority of Daljeet Singh to enter into the contract on behalf of the respondents extended also to clause (17) of the contract and in any event	 the conduct of all the partners showed that Daljeet Singh had authority on behalf of the other partners to enter into the arbitration agreement contained in clause (17) of the contract. The second ground	 however	 found favour with the High Court which held that in view of the bifurcation of the Ministry of Food and Agriculture into two separate Ministries	 487 one of Food and the other of Agriculture	 by the Presiden tial Order	 which came into effect from 19th October	 1956	 the arbitration agreement in clause(17) of the contract became dead and unenforceable and nothing that happened thereafter could revive it and in any event	 even after reintegration of the Ministry of Food and Agriculture into one single Ministry of Food and Agriculture	 the arbitra tion agreement could not be given effect to since there were then two Secretaries in the Ministry of Food and Agriculture and clause (17) of the contract did not indicate as to which Secretary was to exercise the power of nomi nating the arbitrator	 with the result that the arbitration agreement suffered from the fault of vagueness and uncer tainty. The High Court accordingly allowed the appeal and set aside the award made by the Arbitrator. Hence the present appeal by the appellant with special leave obtained from this Court. The only question debated before us in this appeal was as to whether the appointment of the arbitrator by the Secretary	 Department of Food in the Ministry of Food & Agriculture was a valid appointment. Obviously	 if the appointment was invalid	 the arbitrator would have no juris diction to arbitrate upon the disputes between the parties and the award would be invalid. But	 an alternative argument was also advanced on behalf of the appellant to sustain the award and it was that the respondents not having raised any objection to the appointment of the arbitrator and participated in the arbitration proceedings without any demur or protest	 it was not open to them	 after the award was made	 to challenge it on the ground of invalidity of appointment of the arbitrator. The respondents	 having taken the chance of obtaining the award in their favour	 could not denounce the award when it went against them. We will first examine whether the appointment of the arbitrator was valid	 for	 if it was	 the second question	 which raises the issue of waiver	 would not arise. Now	 clause (17) of the contract provided that all disputes arising out of the contract shall be resolved by arbitration. It embodied an arbitration agreement between the parties. It also laid down the machinery for appoint ment of the arbitrator. It provided that the arbitrator shall be nominated by the Secretary in the Ministry of Food & Agriculture in his absolute discretion. There was un doubtedly a Ministry of Food & Agriculture at the time when the contract was made and there was one and only one Secre tary in that Ministry	 so that at the date of the contract there could be no question as to who was the person autho rised to nominate the arbitrator	 The same position contin ued to obtain also at the time when disputes arose between the parties. But before an arbitrator could be nominated by the Secretary in the Ministry of Food & Agriculture to adjudicate upon these disputes	 the Ministry of Food & Agriculture was bifurcated into two separate Ministries and it ceased to exist as Ministry of Food & Agriculture. Then obviously there was no individual who fiIIed the description of "Secretary in the Ministry of Food & Agriculture" and	 consequently the machinery for appointment of the arbitrator became unworkable. If the matter had rested there	 a ques tion could well have arisen whether	 despite the break down of the machinery for nomination of an arbitrator	 the arbi tration agreement in clause (17) 15 1104SCI/76 488 could still be enforced by the Court by appointing an arbi trator in a proceeding under section 20 of the . But the position again changed and the Ministry of Food & Agriculture came into being as a result of integra tion of the Ministry of Food and the Ministry of Agricul ture	 with this change	 namely	 that the new Ministry of Food & Agriculture had two departments	 one of Food and the other of Agriculture and there was a Secretary incharge of each department. There were thus	 after integration	 two Secretaries in the Ministry of Food & Agriculture and the argument of the respondents was and that argument found favour with the High Court that this event rendered the arbitration agreement vague and uncertain	 inasmuch as it did not specify which of the two Secretaries was to nominate the arbitrator "in his absolute discretion". Though this argument appears attractive at first sight	 a little scruti ny will reveal that it is unsound. It is based on a highly technical and doctrinaire approach and is opposed to plain commonsense. it must be remembered that a contract is a commercial document between the parties and it must be interpreted in such a manner as to give efficacy to the contract rather than to invalidate it. It would not be right while inter preting a contract	 entered into between two lay parties	 to apply strict rules of construction which are ordinarily applicable to a conveyance and other formal documents. The meaning of such a contract must be gathered by adopting a commensense approach and it must not be allowed to be thwarted by a narrow pedantic and legalistic interpretation. Here	 at the time when the arbitrator came to be nominated and the reference was made	 there was a Ministry of Food & Agriculture and there was a Secretary in that Ministry	 but the only difficulty	 according to the High Court	 was that there were. instead of one	 two Secretaries and it could not be predicated as to which Secretary was intended to exercise the power of nominating an arbitrator. We do not think this difficulty is at all real. Let us consider	 for a moment	 why in clause (17)	 the power to nominate an arbitrator was conferred on the Secretary in the Ministry of Food & Agri culture and not on a Secretary in any other Ministry. The reason obviously was that at the date of the contract the Secretary in the Ministry of Food & Agriculture was the Officer dealing with the subject matter of the contract. If this object and reason of the provision of clause (17) is kept in mind	 it will become immediately clear that the "Secretary in the Ministry of Food & Agriculture"authorised to nominate an arbitrator was the Secretary incharge of the Department of Food who was concerned with the subject matter of the contract. The Secretary incharge of the Department of Food filled the description "Secretary in the Ministry of Food & Agriculture" 'yen in clause (17). The respondents relied strongly on the use of the definite article 'the ' before the words "Secretary in the Ministry of Food & Agri culture" and urged that what the parties to the contract had in mind was not a Secretary in the Ministry of Food & Agri culture	 but the Secretary in the Ministry of Food & Agri culture and that clearly postulated one definite Secretary in the Ministry of Food & Agriculture and not one of two Secretaries in that Ministry. This is	 in our opinion	 a hyper technical argument which seeks to make a 489 fortress out of the dictionary and ignores the plain intend ment of the contract. We fail to see why the Secretary in the Ministry of Food & Agriculture incharge of the Depart ment of Food could not be described as the Secretary. He would be the Secretary in the Ministry of Food & Agriculture concerned with the subject matter of the contract and dearly and indubitably he would be the person intended by the parties to exercise the power of nominating the arbitra tor. The parties to the contract obviously could not be expected to use the words "a Secretary in the Ministry of Food & Agriculture"	 because their intendment was not that any Secretary in the Ministry of Food & Agriculture should be entitled to exercise the power of nominating an arbitra tor	 but it should only be the Secretary in the Ministry of Food & Agriculture concerned with the subject matter of the contract. That is why the use of the definite article 'the '. It is also significant to note that when the Secre tary in charge of the Department of Food in the Ministry of Food & Agriculture nominated the arbitrator	 the respondents did not raise any objection to the appointment of the arbi trator and participated in the arbitration proceedings without any protest. The respondents knew at that time that there were two Secretaries in the Ministry of Food and Agriculture and the appointment of the arbitrator was. made by the Secretary in charge of the Department of Food and yet they acquiesced in the appointment of the arbitrator and took part in the proceedings. This circumstance is also clearly indicative of the intendment of the parties that the Secretary in the Ministry of Food & Agriculture concerned with the subject matter of the contract should be the person entitled to nominate the arbitrator. Or else the respondents would have objected to the appointment of the arbitrator and declined to participate in the arbitration proceedings or at any rate	 participated under protest. We are	 therefore	 of the view that the arbitrator was validly nominated by the Secretary in charge of the Department of Food in the Minis try of Food & Agriculture. This view renders it unnecessary for us to consider whether by participating in the proceedings before the arbitrator without objection or protest and taking the chance of obtaining an award in their favour	 the respond ents could be said to have waived the defect in the appointment of the arbitrator. We accordingly allow the appeal	 set aside the order of the High Court and while dismissing the application for setting aside the award	 pass a decree in terms of the award. Having regard to the peculiar facts and circum stances of the case	 we make no order as to costs through out.

The respondent partnership firm	 entered into contract with the appellant for the supply of East German sugar. Provision for arbitration was made in clause (17) of the contract	 and the arbitrator was to be nominated by the Secretary in the Ministry of Food & Agriculture. In the present dispute	 before an arbitrator was nominated	 the Ministry of Food & Agriculture was bifurcated into two separate Ministries and the subject matter of the contract was allotted to the Ministry of Food. The respondents took the stand that there was no longer any Secretary in the non existent Ministry of Food and Agriculture and clause (17) of the contract was a dead letter. The appellant 's proposal to amend clause (17) to suit the changed circum stances	 was rejected by the respondents. Thereafter	 the two Ministries were reintegrated into a Ministry of Food & Agriculture and two Secretaries were put incharge of the two departments. The Secretary	 Food Department	 on a request from the appellant under clause (17)	 appointed an arbitra tor. The respondents served on the appellant a notice under C.P.C. Sec. 80 but instead of proceeding to sue the appel lants	 they submitted to the jurisdiction of the Arbitrator without protest until award was made	 The appellant 's appli cation to the Sub Judge	 Delhi	 for passing a decree in terms of the award was resisted by the respondents who sought to set aside the award	 challenging the validity of the Arbitrator 's appointment and contending that the arbi tration agreement under clause (17) was made by only one of the partners	 and was not binding on the others. The Sub Judge rejected their objections and made the award a rule of the court. An appeal to the High Court was allowed on the ground that on bifurcation of the Ministries clause (17) of the contract became dead	 and could not be revived on their re integration. Allowing the appeal the Court	 HELD: There were	 after integration	 two Secretaries in the Ministry of Food & Agriculture	 but the argument that this event rendered the arbitration agreement vague and uncertain	 is based on a highly technical and doctrinaire approach and is opposed to. plain common sense. A contract is a commercial document between the parties and must be interpreted in such a manner as to give it efficacy rather than to invalidate it. It would not be right while inter preting a contract entered into between two lay parties	 to apply strict rules of construction which are ordinarily applicable to formal documents. The meaning of such a contract must be gathered by adopting a common sense ap proach and it must not be allowed to be thwarted by a narrow pedantic and legalistic interpretation. The Secretary in the Ministry of Food and Agriculture in charge of the De partment of Food	 would be the Secretary in the Ministry of Food and Agriculture concerned with the subject matter of the contract and under clause (17)	 he would be the person intended by the parties to exercise the power of nominating the arbitrator. Furthermore	 the respondents did not raise any objection to the appointment of the arbitrator and participated in the arbitration proceedings without protest	 indicating the clear intendment of the parties that the Secretary in the Ministry of Food & Agriculture concerned with the subject matter of the contract should be the person entitled to nominate the arbitrator.
