Summarize the following court judgment. Appeals Nos. 98 and 99 of 1960. Appeal from the judgment and order dated April 16	 1958	 and April 11	 1958	 of the Calcutta High Court in Appeal from Original Order and decree Nos. 173 and 151 of 1957	 respectively. H.N. Sanyal	 Additional Solicitor General of Indin	 M. G. Poddar and D. N. Mukherjee	 for the appellant. C.B. Aggarwala and section N. Mukherjee	 for the respondent. May 4. The Judgment of the Court was delivered by VENKATARAMA AIYAR	 J. These are appeals against the judgment of the High Court of Calcutta	 setting aside an award of the arbitrators	 which directed the respondent to pay to the appellants Rs. 41	250 as compensation for breach of contract	 on the ground that the said contract was in con travention of a notification of the Central Government dated October 29	 1953	 and was in consequence illegal and void. The facts are that the appellants own a Jute Mill at Calcutta and carry on the business of manufacture and sale of Jute. On September 7	 1955 they entered into a contract with the respondents who are doing business as 186 dealers in jute	 for the purchase of 750 bales of Jute cutting 'raw) of Pakistan at Rs. 80 per bale of 400 lbs. to be delivered in October	 November and December at the rate of 250 belles every month. Clause 14 of the agreement provides that all disputes arising out of or concerning the contract should be referred to the arbitration of the Bengal Chamber of Commerce. The respondents failed to deliver the goods as agreed whereupon the appellants applied to the Bengal Chamber of Commerce for arbitration in accordance with el. 14 of the agreement. The respondents appeared before the arbitrators	 and contested the claim on the merits. The arbitrators made an award in favour of the appellants for Rs. 41	250 with interest	 and that was filed under section 14(2) of the Indian in the High Court of Calcutta in its original side and notice was issued to the respondents. Thereupon the respondents filed an application in the High Court	 presumably under section 33 of the arbitration Act	 wherein they prayed for a declaration that the contract dated September 7	 1955	 was illegal	 as it was in contravention of the notification of the Central Government dated October 29	 1953	 and that in consequence proceedings taken thereunder before the Chamber of Commerce and the award in which they resulted were all void. The learned Judge on the original side before whom the application came up for hearing dismissed it	 and passed a 'decree in terms of the award. Against both this judgment and order	 the respondents preferred appeals to a Division Bench of the High Court	 Appeals Nos. 154 and 173 of 1957. They were heard by Chakravartti	 C. J.	 and Lahari	 J.	 who hold that the contract dated September 7	 1955	 was illegal as it fell within the prohibition of the notification aforesaid and accordingly allowed the appeal and set aside the award. The appellants 187 then applied for a certificate under article 133 (1) of the Constitution and the same was granted. This is how the appeals come before us. The learned Additional Solicitor General who appeared for the appellants urged the following contentions : (1)On the terms of the arbitration clause the questionwhether the contract dated September 7. 1955	 isillegal is one for the arbitrator to decide and that it was not open to the respondents to raise the same in the present proceedings under section 33 of the 	 (2)The respondents are estopped from questioning the validity of the award by reason of their having submitted to the jurisdiction of the arbitrators. (3)The agreement dated September 7. 1955	 is a non transferable specific delivery contract within section 2(f) of the Act and it is not hit by the notification dated October 29	 1953. We now proceed to discuss these questions seriatim : (1)Taking up the first questions	 cl	 14 of the agreement which provides for arbitration is as follows : "All the matters	 questions	 disputes	 differences and/ or claims arising out of and/ or concerning and/ or in connection with and/ or in consequence of or relating to this con tract including matters relating to insurance and demurrage whether or not the obligations of either or both parties under this contract be subsisting at the time of such dispute and whether or not this contract has been termi nated or purported to be terminated or com 188 pleted shall be referred to the arbitration of the Bengal Chamber of Commerce and Industry under the rules of its Tribunal of Arbitration for the time being in force and according to such rules the arbitration shall be conducted and any Award made by the said Tribunal under the clause. shall be final	 binding and conclusive on the parties. " Now the contention of the appellants is that the clause is general in its terms and is wide enough to include dispute as to the validity of the contract that in consequence the only right of the respondents is to agitate this question before the arbitrators and if the award goes against them to move the Court either to modify it under section 15 of the or to remit it under section 16 or to set it aside under section 30 on the grounds mentioned therein and that the present application for a declaration that the contract is illegal	 and that the arbitration proceedings are without jurisdiction is therefore incompetent and misconceived. it cannot be disputed that the expression "arising out of " or "concerning" or " in connection with" or "in consequence of" or "relating to this contract" occurring in el. 14 are of sufficient amplitude to take in a dispute as to the validity of the agreement dated September 7	 1955 Vide Ruby General Insurance Co. Ltd. vs Pearey Lal 	Kumar (1) But the question is not whether el. 14 is all comprehensive but whether it could be enforced when the agreement of which it forms an integral part is held to be illegal. Logically speaking	 it is difficult to conceive how when an agreement found to be bad	 any portion of it can held to be good. When the whole perishes	 its parts also must perish. 'Ex nihilo nil fit '. On principle therefore it must be held that when an 189 agreement is invalid every part of it including the clause as to arbitration contained therein must also be invalid. That indeed is what has been laid down in the decisions which have been cited before us. The leading case on the subject is the decision of the House of Lords in Heyman vs Dacwins Ltd(1). There the question was whether repudiation of a contract by a party thereto had the effect of annulling ' the arbitration clause contained therein. It was held that it had not. It was in this context that the law as to the circumstances under which an arbitration clause in an agreement would become unenforceable came in for elaborate discussion. Summing up the law on the subject Viscount Simon	 L. C. observed: "If the dispute is whether the contract which contains the clause has ever been entered into at all	 that issue cannot go to arbitration under the clause	 for the party who denies that he has ever entered into the contract is thereby denying that he has ever joined in the submission. Similarly	 if one party to the alleged contract is contending that it is void ab initio (because	 for 	example	 the making of such a contract is illegal)	 the arbitration clause cannot operate	 for on this view the clause itself also is void. But	 in a situation where the parties are at one in asserting that they entered into a binding contract	 but a difference has arisen between them whether there has been breach by one side or the other	 or whether circumstances have arisen which have discharged one or both parties from further performance	 such differences should %be regarded as differences which have arisen "in respect of" or "with regard to" or	 "under" the contract	 and an arbitration clause which. uses these. or similar	 expressions 	should be construed accordingly." (1) 190 Lord Macmillan with whom Lord Russel agreed observed: "If it appears that the dispute is whether there has ever been a binding contract between the parties	 such a dispute cannot be covered by an arbitration clause in the challenged con tract. If there has never been a contract at all	 there has never been as part of it an agreement to arbitrate. The greater includes the less. Further	 a claim to set aside a contract on such grounds as fraud	 duress or essential error cannot be the subject matter of a reference under an arbitration clause in the contract sought to be set aside. " in the speech of Lord Wright there are the following observations on which the appellants rely: "Hence	 if the question is whether the alleged contract was void for illegality or being voidable was avoided because induced by fraud or misrepresentation	 or on the ground of mistake	 it depends on the terms of the submission whether the dispute falls within the arbitrator 's jurisdiction. " The argument is that if the arbitration clause is general and unqualified it will include a question as to the legality of a contract also. The above observation does lend support to the view that if it was a term of the contract that a dispute as to its legality could be referred to arbitration	 then it is valid. If that is what was meant by Lord Wright it maybe difficult to reconcile it with the view expressed in the passages already cited. But it is to be noted that the noble Lord wound up with the following observation "Finally	 I agree with the general conclusions on the matter summarised by the Lord Chancellor in the closing paragraphs of his opinion". The appellants also rely on the following observations in the speech of Lord Porter: "If two parties purports to enter into a contract and a dispute arises whether they have done so or not	 191 or whether the alleged contract is binding on them. I see no reason why . hey should not submit that dispute to arbitration. Equally I see no reason why	 if at the time when they purport	 to make the contract they foresee the possibility of such a dispute arising	 they should not provide in the contract itself for the submission to arbitration of a dispute whether the contract ever bound them or continues to do so. . It may require very clear language to effect this result	 and it may be true to say that such a contract is really collateral to the agreement supposed to have been made	 but I do not see why it should not be done". But these dicta must be read with the following observations in the same speech: "Where the contract itself is repudiated in the sense that the original existence or its binding force is challenged	 e. g.	 where it is said that the parties never were ad idem	 or where it is said that the contract is voidable ab initio (e. g.	 in cases of fraud	 misrepresentation or mistake) and that it has been avoided	 the parties are not bound by any contract and escape the obligation to perform any of its terms including the arbitration clause unless the provisions of that clause are wide enough to include the question of jurisdiction" According to Lord Porter	 then; there can be an agreement to refer a dispute as to the validity of a contract to arbitration	 that where such an agreement is part of the contract which is impugned as invalid	 then it can have no existence apart from it and there can be no reference based thereon	 but where such an agreement is distinct and separate from the impugned contract. a reference pursuant thereto will be valid and if is possible that both these agreements might be contained in one document. 192 The law is thus summarised in Halsburys Laws of England	 Third Edition	 Vol. 2	 p. 24	. par& 56: The matter in question in the legal proceedings which it is sought to stay must be within the scope of the arbitration agreement. . . If	 however	 the point in dispute is whether the contract containing the clause was ever entered into at all	 or was void ab initio	 illegal	 or obtained (for example) by fraud duress or undue influence	 the clause does not apply and a stay will be refused. " This question arose incidentally for discussion in the Union of India vs Kishorilal Gupta and Brothers(1) where on an examination of the authorities	 including Heyman vs Darwins Ltd. (2) this Court held that an arbitration clause embodied in an agreement is an integral part thereof and that it that agreement is non est either because. it was never legally in existence or because it was void ab initio. 	 then the arbitration clause would also perish with it. Similar decisions had been given in Tolaram Nathmull vs Birla Jute Mfg. Company Ltd.(3) and Hussain Kasam Dada vs Vijayanagaram Commercial Association(4). Reference might in this connection be made to section 33 of the which enacts that a party to an arbitration agreement who desires to challenge the existence or validity of an arbitration agreement should apply to the Court for determination of the question. This section represents the law on the subject as understood in England at the time of that legislation and as declared later by the House of Lords in Heyman vs Darwins Ltd. (2). The scope of section 33 came up for consideration before this Court in Shiva Jute Baling Ltd. vs Hindley & Co. Ltd. (5). There a petition had been filed under that section praying inter alia for a declaration that the contract between the parties containing an (1) ; (2) I. (3)) A.I.R. 1945 Mad. (4) ; (5) (1861) 30 Law. J. Rep. (N.S.) Banks. 193 arbitration clause	 was void ab initio on the ground of uncertainty and that there was in fact no contract owing to mutual mistake and it was held that these were questions for decision by Courts and not by arbitrators. We are accordingly of the opinion that the dispute that the contract ' dated September 7	 1955	 is illegal and void is not one which the arbitrators are competent to decide under cl. 14 and that inconsequence the respondents are entitled to maintain the present application under section 33 of the . (2)It is next contended for the appellants 	that even if cl. 14 should be held to be inoperative by reason of the fact that the dispute is one relating to the validity of the contract	 the respondents are estopped from now challenging the award on that ground	 because they appeared before the arbitrators and took part in the proceedings before them. The decision in Ex p. Wyld (1) is relied on in support of this contention. In that case a dispute between an assignee in bankruptcy and a creditor	 Mr. Wyld	 was referred to arbitration on the	 basis of an agreement in writing between them. An award having been pronounced against Mr. Wyld	 he disputed its validity on the ground that the assignee had not obtained the leave of the Court for entering into the arbitration. In rejecting this contention the Court observed that under the law the agreement was binding on Mr. Wyld even though the leave of the Court was not obtained and that therefore he was not entitled to take this objection based on the informality of the submission as he had himself acted on it. This decision is clearly of no assistance to the appellants because there was a valid and subsisting submission on which the jurisdiction of the arbitrators to bear the dispute was complete	 and that was not affected by the failure of the assignee to obtain the requisite (1) (1861) 30 Law J. Ref. (N.S.) Bankr. 194 leave because that was a matter between him and the Court. But here if the agreement dated September 7	 1955	 is void then there was no submission which was alive on which the arbitrators could act and the proceedings before them would be wholly without jurisdiction. If there had been another arbitration agreement apart from and independent of cl. 14 of the contract dated September 7	 1955	 it might have been possible to sustain the proceedings before the arbitrators as referable to that agreement. But none such has been set up or proved in the present case. All that is alleged is that the respondents acquiesced in the proceedings. But what confers jurisdiction on the arbitrators to hear and decide a dispute is an arbitration agreement as defined in section 2(a) of the 	 and where there is no such agreement	 there is an initial want of jurisdiction which cannot be cured by acquiescence. It may also be mentioned that the decision in exhibit p. Wyld (1) has been understood as an authority for the position that when one of the parties to the submission is under a disability that will not be a ground on which the other party can dispute the award if he was aware of it. Vide Russel on Arbitration	 16th Edn	 p	 320. We are therefore Unable to accept the contention of Mr. Sanyal	 that the respondents are estopped by their conduct from questioning the validity of the award. (3)We may now proceed to consider the question whether the contract dated September 7	 1955	 is illegal as falling within the prohibition enacted in the notification of the Central Government dated October 29	 1953. It will be convenient to set out the relevant statutory provisions bearing on this question. Section 2(i) of the Forward Contracts (Regulation) Act	 1952	 (Act 74 of 1952) hereinafter referred to as 'the Act ' (1) (1861) 30 Law J. Ref. (N.S.) Bank. 10 . 195 defines ready delivery contract ' as meaning "a contract which provides for the delivery of goods and the payment of a price therefore	 either immediately or within such period not exceeding eleven days after the date of the contract". 'Forward contract ' is defined in section 2(c) as meaning "a contract for the delivery of goods at a future date and 'which is not a ready delivery contract". Section 2(m) defines specific delivery contract ' as meaning "a forward contract which provides for the actual delivery of specific qualities or types of goods during a specified future period at a price fixed thereby or to be fixed in the manner thereby agreed and in which the names of both the buyer and the seller are mentioned". Section 2(f) defines 'nontransferrable specific delivery contract ' as meaning "a specific delivery contract the rights or liabilities under which or under any delivery order	 railway receipt	 bill of lading	 warehouse receipt or any other document of title relating thereto are not transferable" and finally section 2(n) defines transferable specific delivery contract as meaning "a specific delivery contract which is not a non transferable specific delivery contract". Chapter IV of the Act contains provisions conferring authority on the Central Government to prohibit certain classes of forward contracts. 	Section 15(1) of the Act enacts: "15(1) The Central Government may by notification in the Official Gazette	 declare this section to apply to such goods or class of goods and in such areas as may be specified in the notification	 and thereupon	 subject to the provisions contained in section 18	 every forward contract for the sale or purchase of any goods specified in the notification which is entered into in the area specified 196 therein otherwise than between members of a recognised association or through or with any such member shall be illegal. " Where a notification has been issued under 15(1) it is provided in section 16 that all forward contracts falling within the notification shall be deemed to be closed out and that the seller shall not be bound to give and the buyer shall not be bound to take delivery of the goods". Then comes section 17 which is as follows: "1711). The Central Government may	 by notification in the Official Gazette	 declare that no person shall	 save with the permission of the Central Government	 enter into any forward contract for the sale or purchase of any goods or class of goods specified in the notification and to which the provisions of section 15 have not been made applicable	 except to the extent and in the manner	 if any	 as may be specified in the notification. (2)All forward contracts in contravention of the provisions of subsection (1) entered into after the date of publication of the notification thereunder shall be illegal. (3)Where a notification has been issued under subsection (1)	 the provisions of sec tion 16 shall	 in the absence of anything to the contrary in the notification	 apply to all forward contracts for the sale or purchase of any goods specified in the notification entered into on or before the date of the notification and remaining to be performed after the said date as they apply to all for ward contracts for the sale or purchase of any goods specified in the notification under sec tion 15. " 197 Section 18(1) provides that these provisions shall not apply to non transferable specific delivery contracts for the sale or purchase of any goods. To analyse the scheme of the Act; it divides Contracts of sale of goods into two categories	 'ready delivery contracts	 and 'Forward Contracts '. Forward Contracts are classified into those which are Specific delivery contracts ' and those which are not. 	 Then again "specific delivery contracts ' are divided into transferable specific delivery contracts ' and non transferable specific delivery contracts. ' Section 18(1) exempts from the operation of the Act "non transferable specific delivery contracts '. The net result of these provisions is that all forward contracts except those which are non transferable specific delivery contracts can be declared illegal by notification issued under the Act. Such a notification was issued by the Central Government in exercise of the powers conferred by section 17 of the Act	 on October 29	 1953. It is as follows : "No. 2(24) Jute/53 In exercise of the powers conferred by section 17 of the Forward Contracts (Regulation) Act	 1952 (LXXIV of 1952)	 the Central Government hereby declares that no person shall enter into any forward contract other than a nontransferable specific delivery contract for the sale or purchase of raw jute in any form	 except to the extent and in the manner specified below	 that is to say: (1)all forward contracts	 other than non transferable specific delivery contracts for the sale or purchase of raw jute entered into before the date of this notification and repaining to be Performed after the said date 198 shall be deemed to be closed out at the rate prevailing at the time at which the Forward Market closed on the said date: (2)all differences arising out of any contracts so deemed to be closed out shall be payable on the basis of the rate specified in clause (1) of this notification and the seller shall not be bound to give and the buyer shall not be bound to take delivery of raw jute. " The contract with which we are concerned in these appeals was entered into on September 7	 1955	 when the notification aforesaid was in force	 and so it would be hit by it	 unless it is a non transferable specific delivery contract and the point for decision is whether it is that. There is no dispute between the parties that it is a specific delivery contract. It is between named buyers and sellers the goods are specified	 as also the period during which they have to be actually delivered and their price is fixed. What is in controversy is whether it is transferable or non transferable. There was considerable argument before us on the question as to assignability of a contract. The law of the subject is well settled and might be stated in simple terms. An assignment of a contract might result by transfer either of the rights or of the obligations thereunder. But there is a well recognised distinction between these two classes of assignments. As a rule obligations under a contract cannot be assigned except with the consent of the promisee	 and when such consent is given	 it is really a novation resulting in substitution of liabilities. On the other hand rights under a contract are assignable unless the contract is personal in its nature the rights are incapable of assignment either under the law or under an agreement between the parties. 199 In the light of the principles stated above	 we shall now consider whether the contract dated September	 7	 1955	 is or is not transferable. As it is only a benefit under a contract that can be assigned	 the discussion really centres round two questions	 are the buyers entitled to assign their right to got the goods on payment of price ? And are the sellers entitled to assign their right to receive the price on delivery of the goods ? On the question as to the rights of the buyers to assign their right to the goods	 the matter is clear beyond all doubts	 The licence which authorises the appellants to import the goods from East Pakistan also prohibits them expressly from assigning the same. In this connection it should be noted that	 owing to the exigencies of Foreign Exchange	 there have been in force	 at all material times	 restrictions on import of goods. The nature of these restrictions and the policy behind them were examined by this Court quite recently in Daya vs Joint Controller of imports and Exports (1) and it is unnecessary to repeat them. It is sufficient for the present purpose to state that the issue of import licences by the Government was restricted to persons who had been engaged in the business of import during a specified period and there were also limitations on the extent to which they could import. Manufacture of jute occupies the pride of place among the industries of West Bengal. Raw jute required for the business is largely imported from East Pakistan	 and for that purpose import licences were being granted from time to time	 to manufactures of jute. During the period of the contract with which we are concerned the appellants held two import licences from the Government of India (1) No. A 062290/52 and (2) A 063733/52. The licence No. A 062291)/52 which is in the standard. (1) ; 200 form is. so far as it is material for the present dis cussion	 as follows: "Import Trade Control. Office of the Joint Chief Controller of Imports	 Calcutta. Licence No. A 062290152/A.U./C.C.I/C. For Exchange Control purposes only. Class of Importer. Actual User or Contract. (Valid at any Indian Port). (Not transferable except under a letter of authority from the authority who issued the licences or from any Import Trade Controller). Messrs. Khardah Co. Ltd. of 7. Wel lesley Place	 Calcutta are hereby authorised to import the goods of which particulars are given below : 1. Country from which consigned . Pakistan 2. Country of origin . " 3. Description of goodsRaw Jute . Raw Jute 4. Serial No. and part of the I.T.C. Schedule . 174 IV 5	 Quantity . 50	000 Mds. (Fifty thou . sant ma . unds only). This licence is issued subject to the condition that the goods will be utilised only for consumption as raw material or accessories in the licence bolder 's factory and that no portion thereof will be hold to any party. " 201 It will be noticed that the licence is non transferable and that further the goods to be imported are not to be sold to any party but to be utilised for manufacture in the factory of the licencee. In view of the terms of the licence there can be no question of assignment of the contract by the buyers. That is not disputed. Turning next to the sellers	 can they assign their right to the price on delivery of the goods ? The learned Judges in the Court below held that they could	 because there was noting personal in the contract	 and nothing in its terms which barred the right to assign a benefit which a party had under the general law. The appellants assail the correctness of this decision. They contend the terms of the contract must be construed in the light of the surrounding circumstances	 and especially of the import licence	 and that if that is done	 the pro.per conclusion to come to is that the agreement is not transferable. This contention must now be examined. The appellants sought	 in the first instance	 to establish on the basis of clauses 12 and 14 that the agreement is personal in its character	 and is therefore not assignable. Now the contract in question is one for the sale of goods	 and ordinary there can be nothing personal about it. It is of no consequence to the buyer as to who delivers the goods. What matters to him is that the goods delivered should be in accordance with the specifications. But it is argued that the status of the parties was a determinative factor in the making of the agreement	 and that is sought to be deduced from el. 12 of the contract. That clause provides that if either or both the parties to the contract are members of the Indian Jute Mills Association and if either of them is placed in the disapproved list of Association then the contract shall be deemed to 202 have been broken by that party. That shows	 it is said	 that the contract was entered into on the faith of the status of the parties as members of the Jute Mills Association. But it is clear from the wording of the clause that the parties to the contract need not necessarily be members of the Association and that being so	 the element of status does not enter into it. Clause 14	 Which is the arbitration clause	 is also relied on as an indication that the contract is personal in its character and incapable of assignment on that ground. But it is settled law that an arbitration clause does not take away the right of a party to a contract to assign it if it is otherwise assignable. Vide Shayler vs Woolf (1) and Russel on Arbitation	 16th Edition	 p. 65. It is also argued that the rights conferred on the 'sellers under el. 8 are incapable of assignment in law	 and that is an indication that the rights under the agreement are not transferable. Clause 8 confers on the sellers certain rights against buyers	 such as the rights to resell and so forth	 when the latter refuse to accept the documents. What is said is that these rights cannot be assigned in law as they are really claims founded on breach of contract by the buyers. That undoubtedly is so	 but that does not conclude the question. There is in law a clear distinction between assignment of rights under a contract by a party who has performed his obligations thereunder	 and assignment of a claim for compensation which one party has against the other for breach of contract. The letter is a mere claim for damages which cannot be assigned in law	 the former is a benefit under an agreement	 which is capable of assignment. The fact therefore that the rights under el. 8 are incapable of assignment does not stand in the way of the respondents assigning their rights to receive the ice after they had performed their obligations. Pr (1) 203 That brings us on to cl. 3 on which the appellants mainly. Under that clause the sellers are entitled to receive the price only on their delivering to the buyers the full set of shipping documents. Now the argument is that as the delivery of documents and payment of cash are to be simul taneous	 it is a case of benefit under a contract being burdened with a liability	 and that such a benefit is incapable of assignment under the law. The learned Judges in the Court below took the view that there was nothing in this clause which prevented the seller from transferring the documents to a third party authorising him to deliver them to the buyers	 and then to receive the price from them	 and they further observed. "Although in presenting the shipping documents the transferee from the seller may act as his agent	 he will not be an agent in receiving payment from the buyer	 because the right to receive the payment has been transferred to him and has become his own right". The respondents maintain that that is the correct view to take of the rights of the parties under this clause and rely on the statements of law in Halsbury 's Laws of England	 and the decision British Waggon Co. vs Lea (1). In Halsbury 's Laws of England	 3rd Edn.	 Vol. 8	 p. 258	 para 451	 the law is thus stated : "There is	 however	 no objection to the substituted performance by a third person of the duties of a party to the contract where the duties are disconnected from the skill	 character	 or other personal qualifications of the party to the contract. ID such a circumstance	 however	 the liability of the original contracting party is not discharged	 and the only effect is that the other party may be able to look to the third party for the performance of the contractual obligations in addition to the original contracting party". In British Waggon Co. vs leg(1) the facts (1) 	 154. 204 were that a company called the Parkgate Waggon Company had hired waggons to the defendant on the terms that he should pay rent for their use	 and that the Company should execute the necessary	 repairs for them. The company then assigned its rights under the contract to another company called the British Company	 subject to the obligation to execute the repairs. In accordance with his agreement the assignee did execute the repairs. Thereafter Parkgate Waggon Co	 demanded rent from the defendant	 who resisted the claim on the ground that the Company had disabled itself from performing the contract	 by reason of assignment to which he had not consented. In overruling this contention the Court observed that as the work to be done under the contract did not require personal skill Or confidence	 the Parkgate Waggon Company could get it done by any person	 and that would be sufficient performance. This decision would be in point if the respondents had arranged to deliver the jute to the appellants through another person	 and then claimed the price	 and that claim was disputed. But it is not an authority on the question which we have to decide	 whether the assignment of the benefit under the contract burdened as it is with an obligation would itself be valid. It is true that the Court observed in passing "That a debt accruing due under a contract can	 since the passing of the Judicature Acts	 be assigned at law as well as equity	 cannot since the decision in Brice vs Bannister(1) be disputed". But it should be noted that both the companies figured is plaintiffs	 and therefore it is not possible to read chose observation as a decision that an assignment of a benefit burdened with an obligation is valid. It was argued for the respondents that it would have been open to them to first obtain the requisite certificate from the Dank in East Pakistan (1) 205 then deliver it to the appellants	 and then assign their right to the price. But the question is not what could have been done by a seller in a forward contract generally	 but what was in fact contemplated by the parties to this contract under el. 3	 The provisions that the shipping documents in Pakistan should be taken in the name of ' the buyer that the sellers should deliver them to the buyers and receive the price	 and that the goods should be delivered at the Mills of the buyers	 strongly suggest that the intention of the parties was	 that neither of them should assign the contract. Whatever doubts one might have as to the true import of cl	 3 it may be conceded	 that it lends itself to the construction put on it by the learned Judges in the Court below	 the position becomes unmistakably clear when it is construed in the light of the import licence in favour of the appellants. It has been already mentioned that it is this which authorises the appellants to import raw jute from East Pakistan. It is statedly not transferable	 and further the goods imported thereunder are to be used only for consumption in the Mills of the appellants. It is contended for the respondents that they are not parties to this licence and that their rights under the general law to assign benefits under the contract remain unaffected by it. This is to take too narrow a view of the true position. Far from being strangers to the licence	 the evidence clearly establishes that they are very intimately associated with it. On September 26	 1955	 acting under licence No	 A 062290/52 the appellants wrote to the Joint Chief Controller of Imports and Exports	 Government of India	 to "issue a letter of authority in favour of sellers Messrs. Raymon & Company (India) Ltd.	 for 2	500 maunds jute cuttings to be imported from Narayanganj	 (East Pakistan)	 against the above (licence)." 206 The letter of authority was received by the appellants on September 29	 1956	 and they sent it on to the respondents with the following letter "Dear Sirs	 Contract No. 2306 We are sending. here with the Exchange Control Copy of Letter of Authority for 1250 Mds. Jute cuttings against the above." Contract No. 2306 referred to in this letter is the contract dated September 7	 1955	 involved in this dispute. It is on the strength of this letter of authority that the respondents opened a letter of credit with a Bank in East Pakistan and the goods were imported. We have not overlooked the fact that while the contract is dated September 7	 1955	 the licence is dated September 22	 1955	 and the letter of authority to the respondents is even later	 and it might strike one as an anachronism to read the licence and the letter of authority into the contract. But it should be remembered that the licences are in standard form and are renewed from time to time except as to details concerning the imports	 and the course of business followed in the jute market was throughout in conformity with the conditions laid down. in the licence and was of the same pattern. Now the agreement provides that the shipping documents in Pakistan are to be taken in the name of the buyers that the sellers are "to open letter of credit" and that the goods are to be delivered 	at the buyer 's Mill siding". We have no doubt that these terms have been inserted with a view to give effect to the conditions on which licences are granted and that it was the understanding of both the sellers and buyers that the rights under the contract were not to be transferred. 207 But it is argued for the respondents that unless there is in the contract itself a specific clause prohibiting transfer	 the plea that it is not transferable is not open to the appellants and that evidence aliunde is not admissible to establish it and the decision in Seetharamaswami vs Bhagwathi Oil Company(1)	 Hanumanthiah vs Thimanthiah(2) and Hussain Kasam Dada vs Vijayanagaram Comm. Asson. (3) are relied on in support of this position. We agree that when a contract has been reduced to writing we must look only to that writing for ascertaining the terms of the agreement between the parties but it does not follow from this that it is only what is set out expressly and in so many words in the document that can constitute a term of the contract between the parties. If on a reading of the document as a whole	 it can fairly be deduced from the words actually used therein that the parties had agreed on a particular term	 there is nothing in law which prevents them from setting up that term. The terms of a contract can be expressed or implied from what has been expressed. It is in the ultimate analysis a question of construction of the contract. And again it is well established that in construing a contract it would be legitimate to take into account surrounding circumstances. Therefore on the question whether there was an agreement between the parties that the contract was to be non transferable	 the absence of a specific clause forbidding transfer is not conclusive. What has to be seen is whether it could be held on a reasonable interpretation of the contract	 aided by such considerations as can legitimately be taken into account that the agreement of the parties was that it was not to be transferred. When once a conclusion is reached that such was the understanding of the parties	 there is nothing in law which prevents effect from being given to it. That was the view (1) (2) A.I.R. 1954 Mod. 87. (3) A.I.R. 1958 Mad. 528	 531. 208 taken in Virjee Daya & Co. vs Ramakrishna Rice & oil Mills(1)	 and that in our opinion is correct. It remains to deal with one other question on which the parties have been at issue. It turns on a consideration of section 2(f) of the Act. A non transferable specific delivery contract is defined in section 2(f)	 omitting what is not material	 as a specific delivery contract the rights or liabilities under which are not transferable. Now the contention of the appellants is that as admittedly the liabilities under the contract are not transferable it is a non transferable contract within section 2(f). But the res pondents argue that on that construction no forward contract will be hit by the notification because liabilities under the contract can never be transferred and so the notification would become futile. They accordingly contend that word or ' should be read as an& and that on that construction unless both the rights and liabilities under the contract are non transferable it is not a non transferable contract as defined in a. 2(f). The appellants urge that on this construction no contract would be non transferable as rights under a contract can always be transferred unless it is personal in its character and the section would become practically useless. The intention of the legislature as expressed in the section is	 it must be admitted	 clouded in obscurity and uncertainty. But in the view we have taken	 that the contract is on its terms properly construed	 non transferable	 it becomes unnecessary to decide between the arrival contentions as to the true import of section 2(f). In the result the appeals are allowed with costs one set throughout and one hearing fee. Appeals allowed. (1) A.I.R. 1956 Mod.

On September 7	 1955	 the appellant company entered into a contract with the respondents for the purchase of certain bales of jute cuttings to be delivered by the respondents in equal installments every month in October	 November and December	 1955. Under cl. 3 of the agreement the sellers were entitled to receive the price only on their delivering to the buyers the full set of shipping documents. Clause 8 conferred on the sellers certain rights against the buyers such as the right to resell if the latter refused to accept the documents. Clause 14 provided that all disputes arising out of or concerning the contract should be referred to the arbitration of the Bengal Chamber of Commerce. As the respondents failed to deliver the goods as agreed the appellants applied to the Bengal Chamber of Commerce for arbitration. The respondents appeared before the arbitrators and contested the claim	 but an award was made in. favour of the appellant. Thereupon the respondents filed an application in the High Court of Calcutta under section 33 of the 	 184 challenging the validity of the award on the ground that the contract dated September 7	 1955	 was illegal as it was in contravention of the notification of the Central Government dated October 29	 1953	 issued under section 17 of the Forward Contracts (Regulation) Act	 1952	 which declared that no person shall enter into any forward contract other than a nontransferrable specific delivery contract for the sale or purchase of raw jute in any form. . . The appellant pleaded (1) that on the terms of the arbitration clause the question whether the contract dated September 7	 1955	 was illegal was one for the arbitrator to decide and that it was not open to the respondents to raise the same in proceedings under section 33 of the ; (2 ) that the respondents were estopped from questioning the validity of the award by reason of their having submitted to the jurisdiction of the arbitrators ; and (3) that	 in any case	 the contract was a nontransferrable specific delivery contract within section 2 (f ) of the Forward Contracts (Regulation) Act and was not hit by the notification dated October 29	 1933. Held	 that : (1) the dispute as to the validity of the contract dated September 7	 1955	 was not one which the arbitrators were competent to decide under cl. 14 and that in consequence the respondents were entitled to maintain the application under section 33 of the . When an agreement is invalid every part of it including the clause as to arbitration contained therein must also be invalid. Leyman vs Darwins Lid. 	 	 Union of India vs Kighorilal Gupta and Brothers	 ; 	 Tolaram vs Birla Jute Manufacturing Company Lid.	 I. L. R. 	 relied on. (2)the respondents were not estopped by their conduct from questioning the validity of the award. Ex parte Wyld	 (1861) 30 Law J. Rep. (N. section) Bank. 10	 explained. (3)on the true construction of the contract dated Sep tember 7	 1955	 read with the terms of the import licence in favour of the appellant	 the agreement between the parties was that the contract was not to be transferred. In construing a contract it would be legitimate to take into account surrounding circumstances and	 therefore	 on the whether there was an agreement between the parties 185 that the contract was to be non transferable	 the absence of a specific clause forbidding transfer was not conclusive.
