Summarize the following court judgment. Appeal No. 105 of 1966. Appeal from the judgment and order dated February 3	 1961 of the Calcutta High Court in Civil Revision No. 2755 of 1957. D. Narsaraju	 R. M. Mehta and section P. Nayar	 for the appellant. Ganpat Rai	 for respondent No. 1. The Judgment of the Court was delivered by SHAH	 J. G. W. Browne was an employee of the East India Railway and was a subscriber to the State Railway Provident Fund. He elected to be governed by the Provident Fund Sterling Accounts Rules	 whereunder payment of the provident fund credited in his account in rupees was on retirement to be made in sterling. On August 26	 1947	 Browne addressed a letter to the Financial Adviser and Chief Accounts Officer	 East India Railway	 requesting that the provident fund payable to him on retirement may be remitted to him by Bank Draft on the District Bank	 Water Street	 Liverpool. After Browne retired from service	 the Deputy General Manager	 Eastern Railway	 wrote a letter on July 27	 1955	 to the Chief Accounts Officer	 communicating the sanction of the General Manager for payment of the special contribution to provident fund to Browne in sterling in terms of r. 1410(1) of the Railway Establishment Code. Another communication was received from Browne (who had apparently by then migrated to the United Kingdom) on February 22	 1956	 by which he requested that the amount standing to his credit in the Provident Fund Account be remitted to the Westminster Bank	 Birmingham. The Railway Administration then drew two cheques one for Rs. 14	428 8 9 and another for Rs. 23	018 11 10 in favour of the Reserve Bank of India with instructions to the Reserve Bank to convert amounts covered by the cheques into sterling and to transmit the fund in sterling to the bankers of Browne in England. The respondent Radha Kissen Agarwalla had obtained a money decree against Browne and he applied to the 3rd Court of the Subordinate Judge at Alipore for execution of that decree	 and obtained an order for attachment of the cheques lying with the Reserve Bank. The cheques were attached and under orders of the executing court the cheques were encashed and the amount realized was deposited in the executing court. 30 The Union of India claimed immunity from attachment of the cheques on the ground that they represented provident fund money which by section 3 of the 	 was immune from attachment. The execution application filed by Radha Kissen Agarwalla was struck off on December 7	 1956. On the next day Radha Kissen Agarwalla started another execution application and applied for and obtained an order for attachment of the money lying in the executing court in the execution case which had been struck off. The Union of India again applied for removal of attachment on the ground that the money represented provident fund money and was immune from attachment under the law and that the attachment was "illegal and without jurisdiction". The executing court overruled the objection observing "that the attachment issued by the Court on December 8	 1956	 was perfectly in order. the moneys attached by the Court lost their character as Provident Fund moneys long before they were attached and hence they were not immune from attachment	 as claimed by the objector". The Union of India then applied to the High Court of Calcutta in revision. The High Court confirmed. the order passed by the executing court. Rule 1413 of the Provident Fund Sterling Accounts Rules	 insofar as it is relevant	 provides : "(1) Where under these Rules any payment is to be made to the subscriber in sterling (a) the subscriber	 prior to the date on which payment is to be made	 shall send written instructions to the Accounts Officer intimating the place at which payment is to be made	 such place being in a country where the rupee is not legal tender; (b) the Accounts Officer	 on receipt of the	 written instructions referred to in the preceding clause shall remit the amount through a bank for payment at the place at which payment is required." Accounts Officer for payment of the amount standing to his credit in a Provident Fund Account in sterling if the country in which it is to be paid	 the rupee is not legal tender. Browne had given intimation before he retired of his intention to receive the provident fund amount due to him at the foot of the Provident Fund Account in sterling in the United Kingdom. After retirement of Browne	 in order to carry out that obligation	 the Accounts Officer of the Railway made out two cheques in the name of Browne and sent them to the Reserve Bank for conversion of the amount in sterling. The Reserve Bank was the only authority which could permit such conversion in view of the 31 currency restrictions imposed by the Government of India. For purpose of conversion and transmission of the amount to Browne	 the Reserve Bank of India was the agent of the Railway Administration. Until the money was converted into sterling and was transmitted by the Reserve Bank to Browne	 the money remained at the disposal of the Railway Administration. The Railway Administration was in respect of the provident fund money in the position of a trustee for Browne and it had undertaken to discharge its obligation by arranging to have the amount converted into sterling and to remit it to Browne. Under section 60 (1) (k) of the Code of Civil Procedure	 1908	 read with section 3 of the 	 the compulsory deposit in any recognised Provident Fund Account is exempt from attachment in execution of a decree of a civil court. Section 3 ( 1 ) of the 	 provides : "A compulsory deposit in any Government or Railway Provident Fund shall not in any way be capable of being assigned or charged and shall not be liable to attachment under any decree or order of any Civil	 Revenue or Criminal Court in respect of any debt or liability incurred by the subscriber or depositor	 and neither the Official Assignee nor any receiver appointed under the Provincial insolvency Act	 1920	 shall be entitled to	 or have any claim on	 any such compulsory deposit. " The Reserve Bank was	 as already stated	 the agent of the Railway Administration for conversion of the amount into sterling and was not the agent of Browne to receive the amount on his behalf. So long as the money remained under the control of the Railway Administration as provident fund money	 it was exempt from attachment. Clause (b) of r. 1413 (1)	 which we have already noted	 imposed upon the Accounts Officer an obligation to send the amount through a bank for payment at the place at which Payment was required	 and the payment was required either under the first intimation at Liverpool by bank draft or under the later intimation by payment to the bankers of 'Browne at Birmingham. The High Court relied upon illustration (d) to section 50 of the Indian Contract Act in support of the view that by sending the two cheques to the Reserve Bank of India in performance of the manner of Payment prescribed by Browne	 the debt was discharged	 and the money must be deemed to have been paid out to the subscriber Browne. Section 50 of the Contract Act provides "The performance of any promise may be made in any manner	 or at any time which the promise prescribes or sanction 32 It enacts the elementary rule relating to the performance of a promise under a contract : performance has to be in the manner and at the time which the promisee prescribes or sanctions. Browne had not authorised the Reserve Bank to receive payment of the money on his behalf	 nor had he sanctioned payment to the Reserve Bank in discharge of the liability of the 'Railway Administration. Illustration (d) to section 50 of the Contract Act on which reliance was placed by the High Court reads : A	 desire B.	 who owes him Rs.100	 to send him a note for Rs. 100 by post. The debt is discharged as soon as B	 puts into the post a letter containing the note duly addressed to A." The illustration only covers cases in which a creditor has directed the debtor to send him the amount owed by the	 debtor in a certain manner. Browne asked the Railway Administration by the first intimation to send the amount by bank draft and later to the Westminster Bank	 Birmingham. Only after the direction of Browne regarding transmission of the fund was complied with	 the obligation of the Railway Administration could be discharged and not till then. In our view	 the High Court was in error in holding that the money in the hands of the Reserve Bank of India had ceased to be provident fund money and was liable to be attached. It was somewhat faintly suggested that the Union of India had no interest in maintaining an application for removal of attachment. But the Union of India was a trustee for the subscriber of the money. When the amount lying with the Reserve Bank as the agent of the Railway Administration was attached the Union had clearly an interest to maintain the application for removal of attachment. The order of attachment of the amount into which the two cheques drawn by the Railway Administration were converted on encashment was contrary to the terms of section 3 of the . The appeal is therefore allowed and the order passed by the High Court is set aside. There will be no order as to costs. R.K.P.S. Appeal allowed.

B was an employee of the East India Railway and a subscriber to the State Railway Provident Fund. He elected to be governed by the Provident Fund Sterling Account Rules	 according to which payment of his provident fund on retirement was to be made in sterling. B 'addressed letters to the Railway Accounts Officer in August 1947 and again after his retirement in February 1956 requesting that the amounts standing to his credit in the provident fund account be remitted to his bank in the United Kingdom. The Railway administration drew cheques in respect of B 's provident fund in favour of the Reserve Bank of India and instructed that bank to convert the amount into sterling and to transmit it to B 's Bank in the United Kingdom. The respondent had obtained a money decree against B and upon applying for execution of that decree obtained an order for attachment of the cheques lying with the Reserve Bank. The cheques were encashed and the amount realised was deposited in the executing court. The appellant claimed immunity from attachment of the cheques under section 3 of the and the respondent 's execution application was thereupon struck off. On filing a second execution application	 the respondent obtained an order for attachment of the money lying in the executing court. A further application by the applicant claiming immunity from attachment was rejected by the executing court on the ground that the monies attached by the court lost their character as Provident fund monies long before they were attached and were not therefore immune from attachment. The High Court in revision confirmed the order of the executing court. On appeal to this Court	 HELD : Allowing the appeal The order of attachment passed by the executing court was contrary to section 3 of the . The Railway administration was in respect of the provident fund money in the position of a trustee for B and it had undertaken to discharge its obligation by arranging to have the amount converted into sterling and to remit it to B. The Reserve Bank was the agent of the Railway administration for converting and remitting the amount on its behalf. Until the money was converted and transmitted by the Reserve Bank to B	 it remained at the disposal of the Railway administration. So long as the money remained under the control of the Railway administration as provident fund money	 it was exempt from attachment under section 60(1)(k) (PC read with section 3 of the Provident Funds Act	 1925.[131 B F] 29 The High Court was in error in relying on illustration (d) of section 50 of the Contract Act. B had not authorised the Reserve Bank to receive payment of the money on his behalf	 nor had he sanctioned payment to the Reserve Bank in discharge of the liability of the Railway Administration.
