Summarize the following court judgment. ivil Appeal No. 3087 of 1991. From the Judgment and Order dated 23.11. 1990 of the Delhi High Court in F.A.O. (O.S.) 123 of 1989. Kapil Sibal	 D.D. Thakur	 Ms. Lira Goswamy	 A.K. Mahajan	 A.S. Chandhoik	 Ms. Meera Chibar and Dinesh Agnani for the appearing parties. 414 The Judgment of the Court was delivered by K. JAGANNATHA SHETTY	 J. We grant special leave and proceed to dispose of the appeal. The General Electric Technical Services Company (`GET SCO ') had entered into a contract with Indian Airlines which included	 inter alia	 the construction and fabrication of air craft testing centre/engine repair centre in Delhi. The GETSCO in turn entered into a contract with M/s Punj Sons (P) Ltd. respondent 1 for getting that work done for Indian Airlines. As per the contract respondent I was required to provide performance bond equal to 30 per cent of the total value of contract price which was to be split up into two performance bonds partly to be released on completion of the project	 and the balance upon the expiration of the warran ty. The respondent I was also required to furnish a bank guarantee to secure the mobilisation advance of 25 per cent of the contract value. On 28 October	 1986 respondent 1 furnished the bank guarantee to secure the mobilisation advance of Rs. 1	86	00	000. The guarantee was furnished by Hongkong & Shanghai Bank ( 'the Bank ') respondent 2. Respondent I instead of furnishing the two performance bonds	 as agreed upon	 wrote a letter dated 3 September	 1987	 as follows: ". . Sub: Jet Engine Test & Repair Centre at Palam Finance September 3	 1987 Dear Sir	 In terms of above contract we have to submit two separate Bonds for Mobilisation advance & performance guarantee & 25% and 30% of the Contract value. Bank Guarantee for mobilisation advance has already been submit ted and we have not to submit the Performance Bonds for 30% of the Contract value. Since the amount of Performance Bond shall be progres sively utilised over the contract period	 in order to reduce Bank charges and marginal money	 we would like to suggest alternative proposals to meet with your requirements: 415 AA. We propose to submit performance guaran tees for 30% of the contract value duly signed by two directors in their personal capacity and countersigned by Punj Sons (Pvt) Ltd. This Performance bond shall include identical terms & conditions	 as desired in your format. Similar Bond has already been accepted by M/s Hindustan Petroleum Corporation Ltd. Bombay for their Bombay Pune Pipeline Project valued at Rs.7.05 crores. Alternatively	 we would suggest submission of a Composite Bank gurantee where amount vacated by Mobilisation advance shall be utilised by Performance Bank Guarantee amount. This Guarantee shall at any time be valid for equivalent to 30% of the contract value	 to cover unrecovered mobilisation advance and Performance Guarantee amount of the work certified. We have submitted similar Bonds to a number of our customers to their entire satis faction. May we request you to look into the above arrangement and allow us to submit the above Bond or Composite Bank Guarantee under this Contract. Thanking you and assuring you of our best services at all times. " GETSCO has accepted the revised proposal contained in the aforesaid letter. Consequently	 on 25 January 1988	 the Bank furnished a composite bank guarantee for Rs.2	 12	25	000. Out of this composite bank guarantee 15 per cent being Rs. 1	06	12	500 would remain in force until 30 June	 1988 and the balance 15 per cent would remain valid till final acceptance certificate i.e. till 30 June 1989. It seems respondent 1 failed to complete the project within the stipulated time as per contractual specifications despite repeated opportunities to rectify defects and defi ciencies prior to August 1988 and thereafter. GETSCO termi nated respondent 1 's right to continue the project and wrote a letter dated 17 April 1989 to the Bank seeking encashment of the bank guarantee dated 25 January 1988 for Rs. 1	06	 12	500. On the same day the bank issued a cashier 's order No. 2605 for Rs. 1	06	 12	500 in favour of GETSCO. On 18 April 1989 the respondent 1 filed a suit for injunction against GETSCO and the Bank in the High Court and obtained an ex parte injunction at the residence 416 of learned Single Judge restraining the Bank and GETSCO from encashing the bank guarantee. On 11 July 1989 the ex parte injunction was vacated. On the same day respondent 1 preferred an appeal to the Division Bench of the High Court and obtained stay of encashment of he bank guarantee. On 23 November 1990	 the Division Bench allowed the appeal	 set aside the order of learned Single Judge and stayed the encashment of the bank guarantee till the disposal of the respondent 's suit. It seems to us that the Division Bench of the High Court has misconstrued the terms of the bank guarantee and the rights and liabilities of the parties thereunder. The first bank guarantee dated 28 October	 1986 is in these terms: "1. In consideration of General Electric Technical Services co. Inc. Cincinnati	 Ohio	 U.S.A. C/o M/s P.L. Jaitly & co. IE/12	 Jhandewalan Extension	 New Delhi (hereinafter called the owner) having agreed to grant mobilisation advance of Rs.18	600	000 [Rs.

Industrial Area	 Kalkaji	 New Delhi 110019 (hereinafter called Contractor) under the terms and conditions of Tender No. HB 040 I made by and between	 owner and Contractor for Indian Airlines Jet Engine Repair and Test Facilities Phase II Construc tion being undertaken at the Indira Gandhi International Airport	 New Delhi (here in called the Agreement) on the production of Bank Guarantee for Rs.18	600	000 [Rupees eighteen million six hundred thousand only] we	 Hongkong & Shanghai Banking Corporation	 28 Kasturba Gandhi Marg	 New Delhi 110001 (hereinafter called Bank) do hereby undertake to pay to the Owner an amount not exceeding Rs. 18	600	000 [Rs. eighteen million six hundred thousand only]	 against any loss or damage caused to or suffered or would be caused to or suffered by the owner by reason of any breach by the Contractor of the terms and conditions contained in the Agreement. We	 the Bank do hereby undertake to pay the amount due and payable under this Guarantee with demur	 merely on demand from the owner stating that the amount claimed is due by way of loss or damage caused to or would be caused to or suffered by the owner by reason of any breach 417 by the Contractor of any of the terms or conditions contained in the Agreement or by reason of the Contractor 's failure to perform the Agreement. Any such demand made on the Bank shall be conclusive	 as regards the amount due and payable by the Bank under this Guarantee. However	 our liability under this Guarantee shall be restricted to an amount not exceeding Rs.18	600	000 [Rupees eighteen million six hundred thousand only]. We	 the Bank further agree that the Guaran tee herein contained shall remain in force and effect during the period that would be taken for the performance of the Agreement and that it shall continue to be enforceable till all the due of the owner under or by virtue of the Agreement have been fully paid and its claims satisfied or discharged or till the owner certifies that the terms and conditions of the Agreement have been tully and properly carried out by the Contractor and accordingly dis charges the Guarantee. Unless a demand or claim under this Guarantee is made on us in writing on or before the date (named in the Agreement as the end of the warrant/mainte nance period) we shall be discharged from all liability under this Guarantee thereafter. We	 the Bank further agree with the Owner that the owner shall have the fullest liberty without our consent and without affecting in any manner our obligations hereunder to vary any of the terms and conditions of the Agree ment or to extend time of performance by the Contractor from time to time or to postpone for any time or from time to time any of the powers exercisable by the owner against the Contractor and to forbear or enforce any of the terms and conditions relating to the Agreement and we shall not be relieved from our liability by reason of any such variation	 or extension being granted by the owner or any indulgence by the owner to the Contractor or by any such matter or thing whatsoever which under the law relating to sureties would but for this provision have effect of so relieving us. We	 the Bank lastly undertake not to revoke this Guarantee during its currency except with the previous consent of the owner in writing. 418 Notwithstanding anything stated above	 our liability under this Guarantee is restricted to a sum of Rs. 18	600	000 [Rs. eighteen million six hundred thousand only]. Our Guar antee shall remain in force until the (date named in the Agreement as the end of the warrant/maintenance period). Unless a demand is lodged with us on or before that date 13 day of February 1988	 all your rights under the said guarantee shall be forfeited and we shall be relieved and discharged from all liabilities thereafter. " The relevant terms of the second composite bank guarantee dated 25 January 1988 are as follows: "Bank Guarantee No. 86 NDH 918 dt. 28.10.1986 for Rs. 1	86	00	000 favouring M/s General Electric & Technical Services Co. Inc. Under the instructions from our clients M/s Punj Sons (Pvt) Ltd. M 13	 Connaught Place	 New Delhi 110001	 we hereby enhance the value of the above Bank Guarantee upto Rs.21	225	000 [Rupees twenty one million two hundred twenty five thousand only] being 30% of the revised Lumpsum Contract value of Rs.70	750	000 [Rupees seventy million seven hundred fifty thousand only]. This Bank Guarantee shall act 'Composite Bank Guarantee ' for Mobilisation Advance and Performance Bond where in Bank Guarantee	 to the extent of amounts of Mobilisation Advance so recovered	 shall be utilised towards Two Performance Bonds of 15% of the Contract value each valid upto 30th June	 1988 and 30th June	 1989	 respectively. All the other terms and conditions of the original Guarantee will remain unchanged. We	 the Hongkong & Shanghai Banking Corpora tion	 28	 Kastruba Gandhi Marg	 New Delhi 110001	 hereby undertakes not to revoke the Guarantee during the currency except with the previous consent of the General Electric 419 and Technical Services Company Inc. Notwithstanding	 anything contained herein before our liability under this Guarantee is restricted to Rs.21	225	000 [Rupees Twenty One Million Two Hundred Twenty five thousand only] and the recovery of Mobilisation advance from Running Bills Account will be in accordance with the contract	 the Guarantee against such amounts of Mobilisation Advance as so recov ered shall be treated towards performance Guarantee with the intent that after recovery of Mobilisation Advance in full	 the Guarantee shall operate against the full value of Per formance Bond. Out of the said guarantee amount	 the Bank Guarantee amount of Rs.10	612	500 [Rupees ten million six hundred twelve thousand & five hundred only] being the 15% of lumpsum value of the contract shall remain in force till the completion of the Project i.e. upto 30th June 1988 and the Bank Guarantee for the balance amount i.e. Rs.10	612	500 [Rupees ten million six hundred twelve thousand five hundred only] being 15% amount shall remain in force till final ac ceptance certificate till 30th June	 1989. NOTWITHSTANDING anything contained hereinbe fore our liability under this Guarantee will be restricted to Rs.21	225	000 [Rupees twenty one million two hundred twenty five thousands only] until 30th June 1988 and will automati cally stand reduced from Rs.21	225	000 to Rs.10	612	500 (Rupees ten million six hundred twelve thousand and five hundred only) on 30th June	 1988 without further reference to you. Our liability will continue only to the extent of the balance amount of Rs.10	612	500 [Rupees ten million six hundred twelve thousand and five hundred only] after 30th June	 1988 and will be conditional upon a claim being filed with us in writing on or before 30th June 1989. Thereafter our liability under this guarantee shall stand extinguished and we shall be relieved and discharged from all liabilities thereunder. " The second bank guarantee with which we are concerned makes a reference to the first guarantee. It states that the guarantee is a composite bank guarantee for mobilisation of advance and performance bond. It further states that all the other terms and conditions of 420 the original Guarantee will remain unchanged. The liability of the Bank shall automatically reduce from Rs.2	12	25	000 to Rs. 1	06	 12	500 on 30 June 1988	 which will continue even after 30 June	 1988 and will be condi tional upon a claim being filed with the Bank in writing on or before 30 June 1989. In the first guarantee	 the Bank has undertaken to pay to GETSCO the amount guaranteed without any demur merely on demand stating that the amount is due by way of loss or damage caused to or would be caused to or suffered by GETSCO by reason of any breach committed by the respondent on any of the terms or conditions contained in the agreement or by reason of respondent 's failure to per form the agreement. It is also provided that any such demand by GETSCO made on the Bank shall be conclusive as regards the amount due and payable by the Bank under the guarantee. The GETSCO has only sought to enforce the bank guarantee for the balance amount of Rs. 1	06	 12	500 on a complaint that respondent 1	 has failed to perform the contract as per the terms and conditions. The Bank has undertaken to pay this sum of money and it is a commitment of the Bank. The Bank must honour its commitment when demand is made. Indeed	 the Bank was prepared to pay and has in fact issued the Cash ier 's order as per demand from GETSCO	 but the Court has directed the Bank not to pay under the guarantee. The question is whether the Court was justified in restraining the Bank from paying to GETSCO under the bank guarantee at the instance of respondent 1. The law as to the contractual obligations under the bank guarantee has been well settled in a catenae of cases. Almost all such cases have been considered in a recent judgment of this Court in U.P. Cooperative Federation Ltd. vs Singh Consultants and Engineers (P) Ltd.	 wherein Sabyasachi Mukherji	 J.	 as he then was	 observed (at 189) 'that in order to restrain the operation either of irrevocable letter of credit or of confirmed letter of credit or of bank guar antee	 there should be serious dispute and there should be good prima facie case of fraud and special equities in the form of preventing irretrievable injustice between the parties. Otherwise	 the very purpose of bank guarantees would be negatived and the fabric of trading operations will get jeopardised '. It was further observed that the Bank must honour the bank guarantee free from interference by the Courts. Otherwise	 trust in commerce internal and interna tional would be irreparably damaged. It is only in excep tional cases that is to say in case of fraud or in case of irretrievable injustice	 the Court should interfere. In the concurring opinion one of us (K. Jagannatha Shetty	 J.) has observed that whether it is a 421 traditional bond or performance guarantee	 the obligation of the Bank appears to be the same. If the documentary credits are irrevocable and independent	 the Bank must pay when demand is made. Since the Bank pledges its own credit in volving its reputation	 it has no defence except in the case of fraud. The Bank 's obligations of course should not be extended to protest the unscrupulous party	 that is	 the party who is responsible for the fraud. But the banker must be sure of his ground before declining to pay. The nature of the fraud that the courts talk about is fraud of an "egre gious nature as to vitiate the entire underlying transac tion". It is fraud of the beneficiary	 not the fraud of somebody else. The High Court has observed that failure on the part of GETSCO to make a reference to mobilisation advance in the letter seeking encashment of the bank guarantee would be tantamount to suppression of material facts	 in the sense that the mobilisation advance was	 under the contract to be recovered from the running bills. It was further observed that disclosure of such facts would have put the bank to further inquiry as to what was the amount covered by those bills and what was the corresponding amount of the mobilisa tion advance and to what extent the amount covered by the bank guarantee remained payable. In any event	 the High Court said	 that GETSCO could not demand full amount of the bank guarantee on 17 April 1989. It seems to us that the High Court has misconstrued the terms of the bank guarantee and the nature of the inter se rights of the parties under the contract. The mobilisation advance is required to be recovered by GETSCO from the running bills submitted by the respondent. If the full mobilisation advance has not been recovered	 it would be to the advantage of the respondent. Secondly	 the Bank is not concerned with the outstanding amount payable by GETSCO under the running bills. The right to recover the amount under the running bills has no rele vance to the liability of the Bank under the guarantee. The liability of the Bank remained intact irrespective of the recovery of mobilisation advance or the non payment under the running bills. The failure on the part of GETSCO to specify the remaining mobilisation advance in the letter for encashment of bank guarantee is of little consequence to the liability of the Bank under the guarantee. The demand by GETSCO is under the Bank guarantee and as per the terms thereof. The Bank has to pay and the Bank was willing to pay as per the undertaking. The Bank cannot be interdicted by the Court at the instance of respondent 1 in the absence of fraud or special equities in the form of preventing irre trievable injustice between the parties. 422 The High Court in the absence of prima facie case on such matters has committed an error in restraining the Bank from honouring its commitment under the bank guarantee. In the result	 we allow the appeal	 set aside the im pugned judgment and order of the High Court. The appellant is entitled to costs in this Court. S.L.P. (Civil) No. of 1991 (In CC 13 153/91) Since we have set aside the order of the Division Bench of the High Court this Special Leave Petition does not survive and is accordingly dismissed. No costs. V.P.R. Appeal allowed.

The appellant 's contract with Indian Airlines included the construction and fabrication of air craft testing cen tre/engine repair centre in Delhi. For getting that work done	 the appellant entered into a contract with the re spondent 1. As per the contract	 respondent 1 was required to provide performance bond equal to 30 per cent of the total value of contract price	 which was to be split up into two performance bonds partly to be released on completion of the project	 and the balance upon the expiration of the warran ty	 and to furnish a Bank guarantee to secure the mobilisa tion advance of 25 per cent of contract value. Respondent II	 instead of furnishing the two perform ance bonds	 wrote a letter for a revised proposal	 which was accepted by the appellant. As the respondent 1 failed to complete the project within the stipulated time	 as per contractual specifica tions	 despite repeated opportunities	 the appellant termi nated respondent 1 's right to continue the project and sought for encashment of the Bank guarantee for Rs. 1	06	12	500	 which was issued to the appellant by the Bank. The respondent I filed a suit for injunction against the appellant and the Bank in the High Court and obtained an ex parte injunction from the Single Judge	 restraining the Bank and the appellant from encashing the Bank guarantee. When the ex parte injunction was vacated	 respondent I preferred an appeal to the Division Bench of the High Court. The Division 413 Bench allowed the appeal	 staying the encashment Of the Bank guarantee till the disposal of the respondent 's suit. On the question	 whether the Court was justified in restraining the Bank from paying the appellant under the Bank guarantee at the instance of respondent I	 allowing the appeal of the appellant company	 this Court	 HELD: 1. In the instant case	 the High Court has miscon strued the terms of the Bank guarantee and the nature of the inter rights of the parties under the contract. The mobili sation advance is required to be recovered by the appellant from the running bills submitted by the respondent. If the full mobilisation advance has not been recovered	 it would be to the advantage of the respondent. Secondly	 the Bank is not concerned with the outstanding amount payable by the appellant under the running bills. The right to recover the amount under the running bills has no relevance to the liability of the Bank under the guarantee. The liability of the Bank remained intact irrespective of the recovery of mobilisation advance or the non payment under the running bills. The failure on the part of the appellant to specify the remaining mobilisation advance in the letter for encash ment of Bank guarantee is of little consequence to the liability of the Bank under the guarantee. The demand by the appellant is under the Bank guarantee and as per the terms thereof. The Bank has to pay and the Bank was willing to pay as per the undertaking. The Bank cannot be interdicted by the Court at the instance of respondent I in the absence of fraud or special equities in the form of preventing irre trievable injustice between the parties. The High Court in the absence of prima facie case on such matters has commit ted an error in restraining the Bank from honouring its commitment under the bank guarantee. [421E 422A] U.P.
