Summarize the following court judgment. Appeal No. 4702 of 1991. From the Judgment and Order dated 26.8.88 of the Bombay High Court in W.P. No. 2264 of 1984. T. Andharujina	 F.H. Talyarkha	 R.F. Nariman	 R. Narain	 Ashok Sagar and Ms Amrita Mitra for the Appellants. K.K. Singhvi	 B.N. Singhvi and Anil K. Gupta for the Re spondents. The Judgment of the Court was delivered by 451 V. RAMASWAMI	 J. Leave granted. The First appellant Tara Engineering and Locomotive Company Limited (hereinafter called the 'Company ') is a. company registered under the Indian Companies Act	 1913 and the second appellant is one of its Directors. The Company is carrying on business of manufacture and sale of motor vehi cles and spare parts of motor vehicles and excavators. Their manufacturing units are at Pune and Jamshedpur outside the Thane Municipal Corporation limits. They have a bonded warehouse within the municipal limits in which they bring and stock motor vehicles parts 'and excavators parts from their own factories at Pune and Jamshedpur. They also bring in parts manufactured by their ancillaries within India and also parts imported from aboard. These products or parts are brought in bulk and thereafter taken or sent out from the Municipal limits in smaller packings depending on the re quirements of the customers in various parts of the country. It is stated that the parts imported or purchased from others and brought in are relatively very small in quantity and the major portion of the activity related to their own factory produced parts. On and from 1 st October	 1982 with the notification under Section 3 of the Bombay Provincial Municipal Corpora tion Act	 1949	 the Thane Municipal Council became a Munici pal Corporation (hereinafter called the Corporation). Prior to the constitution of the Corporation it was a municipality and were governed by the Thane Municipal Council constituted under the Maharashtra Municipality Act	 1965. Prior to 1 st October	 1982 the Thane Municipal Council had granted to the Company current account facilities in respect of payment of octroi under the Maharashtra Municipalities Act	 1965 and the Maharashtra Municipalities (Octroi) Rules	 1968 made thereunder. The Municipal Council had also granted permis sion under Rule 10 (2) to the Company for maintaining a godown or warehouse of their own. Their is no dispute that even after the coming into existence of the Thane Municipal Corporation the appellants were permitted to have a ware house of their own and keep a current account facility without the requirement of immediate payment of octroi at the Octroi Naka. In terms of granting those facilities the Company had made as security a cash deposit of Rs. 7 lakhs with the Corporation and had also given a Bank Guarantee for an equivalent amount as agreed to between the Company and the Corporation. However	 there is some dispute as to what were the formalities that were dispensed with in the matter of claiming refund of the octroi when the goods were export ed. But suffice it to say at this stage that the appellants were permitted to carry out their activities of imports and exports under the current account procedure with a facility of unpacking the bulk	 repacking and exporting. 452 During the period 1st January	 1983 to 31st March	 1964 it is stated that the appellants had made 1182 claims for refund. All these claims were rejected by the letters of the Corporation dated 31.8.1983	 12.1. 1984	 5.4.1984 and 6.4.1984. They were rejected on the following two grounds: (1) the Company had "sold" the spare parts within the octroi limit (which is co terminus with the Corporation limit) in contravention of Rule 25 (3) (d) of the Maharashtra Munici palities (Octroi) Rules	 1968 (hereinafter called the "Rules")	 (2) the procedure prescribed for export and the claim of refund had not been strictly followed. The non compliance with)the procedure prescribed referred to in the second ground according the Corporation were: (i) Form 4 of the Octroi Rules and the original invoices were not submit ted	 or (ii) Forms 11 and 12 filed were incomplete and all the required information were not given or (iii) certificate of the Octroi exit Naka Officer had not been obtained. The rejection of the claim was either on one or more than one or all the grounds mentioned above. The appellants filed a writ petition under Article 226 in the High Court of Judicature at Bombay contending that the action of the Municipal Corpo ration in refusing refund is unconstitutional and illegal and for certain other reliefs. The Division Bench of the High Court which heard the same dismissed the writ petition on the 26th August	 1988. It is against this judgment that the present appeal has been filed. It appears that during the hearing of the writ petition the learned counsel appearing for the Corporation did not counter the contention of the Company that the rejection under Rule 25 (3) (d) was not correct and the learned Judges have also recorded the same in the judgment. But the learned counsel for the respondent before us stated that it is not correct to say that he had conceded any point and that since he could not argue that point in view of the decision of another Division Bench of the same High Court in Khandelwal Trader Akola vs The Akola Municipal Council	 AIR 1985 Bombay 218 which was binding on the Bench which heard the writ petition and also in view of certain observations of this Court in Burmah Shell Company vs Belgaum Municipal	 [1963] Suppl. 2 SCR 216 and Hiralal Thakorlal Dalai vs Brash Broch Municipality	 he did not press the point. We have therefore	 permitted the point to be argued in this appeal. Before we discuss the points in controversy we may state that in the counter affidavit filed in the writ petition the respondents have admitted that the Company was enjoying the current account facility prior to 1.10. 1982 and the re spondent Corporation had also given the said facility to the Company even after 1st October	 1982 on their making a cash deposit of Rs. 7 Lakhs and furnishing a Bank Guarantee for a like sum as security 453 for grant of that facility. The respondent had also admitted that the Company had been given permission under Rule 10 (2) to maintain their own godown from 12th December	 1982. Broadly stated under the current account facility granted	 no octroi duty is recoverable in cash from the appellants at the entry octroi naka point. However	 the Company was re quired to submit a statement of goods imported in Form 5 before the 10th of the following month. The officers of the respondent after scrutiny of the statement so filed deter mine the octroi duty payable thereon and debit the amount in the current account kept and send a demand notice to the company. The Company is required to pay the amount to the Corporation within 15 days of the determination of duty. The first submission of Mr. Andharujina	 learned counsel for the appellants was that the sales were not for consump tion or use within the octroi limits and that the parts were sold to parties outside the octroi limits and also for consumption or use outside such limits and therefore the rejection of the claims on the ground that the spare parts were sold within the municipal limits and that it amounted to a contravention of Rule 25 (3) (d) of the Rules is ille gal. Mr. K.K. Singhvi	 the learned counsel for the Corpora tion on the other hand contended that the meaning of words "sales therein" in the definition of octroi in the Acts and in Entry 52 of List II could not be limited to sales of the goods for purposes of consumption or use within the munici pal limits. When an importer wants to export dutiable goods tempo rarily detained by him in his own godown he shall present an intimation cumapplication for written permission in Form 11 to the Superintendent of Octroi to export such goods. Rule 25 (3) (d) states that no such intimation shall be accepted unless: .LM15 "the exporter and the importer of these goods are one and the same person and such articles have not undergone change of ownership" .LM0 The case of the Corporation was that there was a change in the ownership of the goods since a sale in law had taken place inside the octroi limits though the purchaser was residing and carrying on business outside the octroi limits and under the sale the goods were intended to be and in fact exported for the purpose of consumption and use outside the octroi limits. Section 127 of the Bombay Provincial Municipal Corporation Act	1949 and the corresponding section 105 of the Maharashtra Municipalities Act	1965 authorises the Muncipality to levy "Octroi". Both these Acts define 454 octroi as meaning a tax on the entry of goods into the municipal area "for consumption	 use or sale therein". The Maharashtra Municipalities (Octroi) Rules 1968 made under the Maharashtra Municipalities Act	 1965	 provides for the levy	 collection and refunds of octroi duty on the goods specified in the schedule thereunder and the procedure for the same. These Rules were in force in Thane Municipality before Thane was declared as "City" under the Bombay Munici pal Corporations Act LIX of 1949. However these Rules are continued in the Thane Municipal Corporation by virtue of paragraph 5 of Appendix IV to the Act LIX of 1949. The legislative entry relating to the constitutional power to levy this tax is found in List II Entry 52 of the 7th Schedule to the Constitution which reads: "52. Taxes on the entry of goods into a local area for consumption	 use or sale therein". The Bombay Municipal Boroughs Act	 1925 which was in force prior to the enactment of the Maharashtra Municipali ties Act	 1965 also contained a similar provision in section 73 enabling the Municipalities covered by that Act to levy "Octroi on animals or goods or both brought within the octroi limits for consumption or use therein". This provi sion was amended by Amending Act 35 of 1954 by substituting the words "use or sale" for the words "or use" with effect from May 5	 1954. In other words before 1954 the word "sale" was not included in the provision of octroi on goods which the Municipality was authorised to impose. After the amend ment the Municipality could levy octroi on goods brought within the octroi limits "for consumption	 use or sale therein". This provision came up for consideration in Burmah Shell case (supra). Two of the categories of transactions which were considered in this case related to transactions under which (1) goods were sold by the Company through its dealers or by itself and consumed within the octroi limits by persons other than the Company and (2) goods sold by the Company through its dealers or by itself inside the octroi limits to other persons but consumed by them outside the octroi limits. The Company contended that the tax could not be collected on goods which were merely sold but not con sumed inside the octroi limits. In connection with this con tention this Court considered the meaning of words "consump tion	 use or sale therein" and observed: "It is not the immediate person who brings the goods into a local area who must consume them him self	 the act of consumption may be post poned or may be performed by someone else but so long as the goods have been brought into the local 455 area for consumption in that sense	 no matter by whom	 they satisfy the requirements of the Boroughs Act and octroi is payable". " . . The goods must be regarded as having been brought in for purposes of consumption when a person brings them either for his own use or consumption	 or to put them in the way of others in the area	 who are to use and consume". And concluded holding: "In our opinion	 the Company was liable to pay octroi tax on goods brought into local area (a) to be consumed by itself or sold by it to consumers direct and (b) for sale to dealers who in their turn sold the goods to consumers within the municipal area irrespective of whether such consumers bought them for use in the area or outside it. The Company was	 however	 not liable to Octroi in respect of goods which it brought into the local area and which was re exported". The ratio is thus not a mere sale inside that attracts octroi but a sale intended for consumption of the goods inside the octroi area though ultimately the person to whom it was sold for consumption does not consume the goods inside but does the same outside the limit. After consideration of the judgment in Burmah Shell Company 's case (supra) the Gujarat High Court in one of the cases arising for refund of octroi duty paid	 took the view that octroi leviable on goods brought within the octroi limits 'for consumption	 use or sale therein ' and that the word 'sale ' could not be given the narrow meaning of a sale for consumption to the ultimate consumer within the octroi limits. Accordingly if the goods were sold within the octroi limits by the importer even if it resulted in export and consumption was also outside the octroi limit	 octroi duty paid is not refundable. This decision came up in appeal before this Court and the decision of this Court is reported in Hiralal Thakorlal Dalai vs Brash Broach Municipality	 On facts that case related to a con signment sale and the goods were despatched to destination outside octroi limits for consumption there. A plea for review of the decision in Burmah Shell Company s case (supra) was also made in this case. However a Constitution Bench rejected the request for reconsideration and held that the word "sale" in the colloquium of the words "consumption	 use or sale therein" means sale for consumption within the octroi limits. The ratio of these two decisions was consid ered by the Bombay High Court in Khandelwal Traders Akola 's case (supra)	 which was referred to in the Judgment under appeal. It was held in this case also 456 that where a dealer imports goods within the octroi limits not for ultimate consumption or sale for consumption within the limits but for the purpose of export and obtain permis sion for export he is not liable to pay octroi on such goods notwithstanding that in the larger sense for purposes of export he sells the goods within the octroi limits	 that is to say even where the situs of the sale could be fixed within the octroi limit. The matter is now put beyond any pale of doubt by the latest decision of this Court in Munic ipal Council	 Jodhpur vs M/s. Parekh Automobiles Ltd. & Ors.	 ; Rule 13 (4) of the Rajasthan Munici pal Octroi Rules	 1962 which was one of the provisions considered in this case provided that "In cases provided for in sub rule (3) (that is who is given the account current facility)amount of octroi duty payable shall be based on the total amount of the octroi as shown by the entry passes less the total amount of goods transported outside the munic ipal limits as shown by the transport passes: Provided that in computing the octroi duty payable under subsection (4)	 the goods trans ported outside the municipal limits shall be lessened only if such goods have not been sold within the municipal limits and if they have been exported out of such limits within a period of six months from the date of their import in such limits". Relying on this provision the municipality in that case contended that if the sale had taken place within the octroi limits though the sale was not for consumption or use within the octroi limits	 duty was payable and no refund could be claimed. The learned Single Judge who heard the matter in the High Court did not permit the importer to raise the question that the sale took place only outside the octroi limits of Jodhpur and proceeded on the footing that the sale of product in question took place within the octroi limits of Jodhpur. He however accepted the contention of the Indian Oil Corporation (importer) that the sale to the dealer was for the purpose of export and the dealer did export the goods outside the octroi limits and that	 therefore	 even if the sale was said to have been effected within the octroi limits no octroi was leviable. Since admittedly the goods had been sold in Jodhpur octroi limits only for their on wards transmission for use and consumption in Dangia was outside the octroi limits he held that no octroi duty was payable. This view of the learned Single Judge was confirmed on appeal by the Division Bench of the High Court. On appeal this Court confirmed this view and held that the Indian Oil Corporation (importer) who had the current account facility and gov 457 erned by the terms of rule 13 was entitled to go on paying octroi duty "on to basis of the goods brought by it within the municipality less the goods transported outside the municipality even where the transport outside the municipal ity may be in pursuance of a sale within the municipality so long as such sale is in pursuance of an intention that the goods should be consumed or used outside the municipal limits". In the present case the sales were to person who were carrying on business outside the limits of the Corporation and the goods were also intended to be consumed or used outside such limits and in fact the goods were also export ed. The ratio of the decisions above referred clearly	 therefore	 governs this case	 even if it were to be assumed that the sale in the general sense took place inside the municipal limits. However we may state that it was the contention of the learned counsel for the appellant that the sale in fact took place outside the municipal limits and in support of this contention he relied on the following facts among others. The spare parts were consigned by the Company to out station purchasers. The goods were transported by the Company them selves across the octroi limits. The consignment or lorry receipt mentioned the consignee as self. The bills for collection were sent through Bank and the goods were not to be delivered to the consignee until the payment was made by the consignee through the Bunk. Right of disposal expressly reserved with the vendor. On the other hand on behalf of the Corporation it was contended that orders were both received and accepted in Thane	 goods were despatched from Thane and challans were also made in the name of the buyers and the property in the goods passed within Thane. The sale had in fact taken place within municipal area. In fact he further contended that being a question of fact we are not entitled to go into the same in view of the finding of the High Court. It is not necessary for us	 however	 to consider this aspect and we would for the purpose of this case proceed on the assumption that technically the sale in law had taken place inside the municipal limits. Since the goods were sold by the Company to outside purchasers and the goods under the transactions of sale	 were intended to be exported and were in fact exported	 for consumption or use outside the municipal limits no octroi duty was leviable and the octroi duty paid on entry into the municipal limits was	 therefore	 liable to be refunded. Accordingly the rejection of the refund claims on the ground that Rule 25 (3) (d) had not been strictly complied with is illegal and could not be sustained. Such of those claims which were rejected only on the grounds of contravetion of 458 Rule 25 (3) (d) shall now be taken up by the respondent and passed for payment. In the case of impost of octroi the taxable event is the entry of goods which are meant to reach an ultimate user or consumer in the area. Mere physical entry into the octroi limits would not attract levy of octroi. When the goods are brought in not for consumption within the area but for temporary detention and eventual export	 octroi is not leviable. But in order to ensure	 in such circumstances	 that the goods are exported and to prevent evasion of octroi on goods consumed inside the octroi limit	 Rules provide for deposit of a certain sum of money or the actual octroi duty payable subject to a right to get a refund of the same when the goods are exported. When the goods in respect of which octroi was paid are exported	 the octroi became refundable and that is the very scheme of the ' levy of octroi. The octroiable event in such a case shall be deemed not have happened. Right to refund arises because the goods are not consumed inside the area but exported and the tax becomes not leviable. The rules merely regulate the system on which refunds shall be allowed. The procedure prescribed and the need to adhere to the procedure shall have to be considered in the light of these legal incidence and nature of octroi duty. Before we deal with the question whether the Company had not followed any of the procedure prescribed and the right of the Corporation to deny refund of octroi on non compli ance with any of those provisions in the Rules	 it is neces sary to broadly set out the different types of procedures prescribed	 depending on different purposes of imports and exports	 contemplated under the Rules. This may be broadly classified into five categories	 (i) goods imported for Consumption	 use or sale in the municipal area	 (ii) goods imported not for consumption	 use or sale within the munici pality but for immediate export	 (iii) goods intended to be temporarily detained within the municipality in the bonded warehouse maintained by the Corporation and eventual export; (iv) goods intended for temporary detention in the private licensed bonded wharehouse of the importer and eventual export; and (v) goods imported by any person	 mercantile firm or body which has been permitted by the municipal Corporation to keep an current account. In the first case	 since octroi is attracted on arrival of the dutiable goods at the Octroi Naka the importer pays the amount of octroi assessed by the octroi officer and takes the goods inside the municipal limits. In the second case	 the importer gives a declaration cum application that the goods are not being imported in the municipal limits for consumption	 use or sale but are intended for immediate export outside the octroi limits. He is required to deposit an amount in 459 accordance with the scale fixed under clause (b) of sub rule (1) of Rule (5). On such deposit being made a receipt is given in the form prescribed by the Entrance Naka Inspector and a written permission cum transit pass issued by the Octroi Officer. On arrival of the goods at the exit Naka and on surrender of the written permission cum transit pass the deposit amount is refunded. In the third category of cases	 the importer makes an application to the Octroi officer at the Entrance Naka for a written permission to deposit such goods at the bonded warehouse maintained by the Corporation. The Octroi Officer then makes an entry on the application that the importer is allowed to proceed with the goods to the bonded warehouse. The Officer in charge of the bonded warehouse will receive the goods and keep them in the bonded warehouse until exported. When the importer wants to export the goods he is required to apply for a written permission cum export pass in the prescribed form and also deposit an amount equal to the octroi leviable therein. On such deposit made a written permissioncum export pass is issued. When the goods are taken out of the municipal limits the Officer Incharge of the Exit Naka endorses the export pass certify ing the export and the refund of the deposit is claimed thereafter producing the certificate issued by the Exit Naka Officer. In the fourth category	 the importer gives a decla ration in Form 4 that the goods are meant for temporary detention with him at his own warehouse for eventual export. After verification of the particulars furnished in that form with the invoices and other documents produced he is re quired to deposit at the Entry Octroi Naka point itself an amount equal to the amount of full octroi duty thereon as deposit. A receipt is given by the Octroi Inspector stating that the said amount "on account of deposit" has been recov ered. When he wants to export the dutiable goods detained with him he presents an intimation cum application in Form 11 for written permission to export the goods. He is also required to produce the goods at the Central Octroi officer along with the application. On satisfaction that all the conditions prescribed have been fulfilled and after verifi cation of the goods a written permission cum refund export pass in Form No. 12 is given to the importer. On presenta tion of these documents the Octroi officer at the Exit Naka gives a certificate that the goods mentioned therein have passed octroi limits and with that the refund application is made and refund obtained. The instant case falls under the fifth category. The Company has been permitted by the Municipal Corporation to keep the dutiable goods in a bonded warehouse of their own with a current account facility. The rules which were relied on by the Respondent and some of which are said to have not been complied with by the Company may be set out: "10. Maintenance of Bonded Warehouses. 460 (1) x x x (2) A Council may permit any importer to maintain a private Bonded Warehouse for keep ing goods which are imported by such importer for temporary detention and eventual export and grant a licence to such importer for that purpose subject to the conditions and restric tions laid down in such licence.

(4) On receipt of a declaration in Form 5 under the last preceding rule	 the Octroi Officer shall ascertain whether the name of the person	 mercantile firm or body on whose behalf the goods are being imported is on the list of persons	 firms or bodies allowed to keep an account current	 and if so	 check the goods with the details entered in the declara tion and fill up the certificate below the declaration and issue a pass in Form 6. The Octroi Officer shall forward all such declara tions together with a list in duplicate there of to the Central Octroi Officer for further action in accordance with the provisions of Section 142.

Signature of Importer On a reading of these rules it appears to be that Rules 24	 25 and 28 in terms would apply only to cases failing under category four	 stated above. The declaration in Form 4 referred to in Rule 24 and deposit of the amount equivalent to octroi duty payable at the entry point	 production of the goods for verification at the Central Octroi Office are all consistent with its being applicable to a case where dutia ble goods are imported for temporary detention and eventual export by a person having a bonded warehouse of his own contemplated in Rule 14 (1) (d) and not Rule 14 (1) (e). However	 Rules 29 and 30 are general in terms and may be invoked in both the cases falling under Rule 14 (1) (d) and (e). Sub rule (3) of Rule 29 refers to the compliance of the conditions in Rule 28 and that is how it may be said that the provisions of Rule 28 are attracted to the cases of a person having a bonded warehouse and the facility of account current. However	 the Rules have to be read and applied in such way that they do not conflict with but are consistent with the facility of current account given to the Company. Form 5 which is applicable to a case falling under Rule 14 (1) (e) does not require the Company (importer) to give a declaration at the time of arrival of the goods at the entry Naka point that the "goods are meant for temporary detention with" the Company at its warehouse "for eventual export outside the octroi limits". The Company need not also make any deposit with the Naka Inspector at the point of entry. An amount equivalent to the octroi duty payable in respect of the goods is only entered in the account current after the goods have reached the warehouse and verified by the Octroi Officer. Form 4is not applicable to the case of the Company which has got a current account facility. The Compa ny	 is	 therefore	 bound to give a declaration only in Form 5	 and need not give a declaration as in Form 4 nor is there any obligation to deposit an amount equivalent to the full octroi duty with the Octroi Inspector at the Entry Naka Point. Further reference to original invoices/in Forms 4 and 5 is only for the purpose of checking the particulars en tered into in the forms. The production of an invoice is not	 having regard to the 470 purpose of such production	 to be insisted blindly. If the particulars furnished in the form including weight/quantity or value could be established satisfactorily by other docu ments	 we have no doubt that will be sufficient compliance with the Rules. Column 5 of Form 11 also refers to invoice and the date of invoice. This is again to correlate the goods exported with the goods imported. If the identity of the goods could be established by evidence other than the production of invoices that should satisfy the Rules. The invoice as such has no bearing on the liability of the goods for octroi or the right of the Company for refund. So far as the production of the original invoices are concerned	 the learned counsel for the Company pointed out that the goods are brought from their own manufacturing units at Pune and Jamshedpur and it will only be a stock transfer and this requirement of producing original invoice could not be complied with and is not applicable. Under the current account procedure the invoices	 if any and all the other documents are verified when the goods reach the ware house with reference to the description of the goods	 weight/quantity	 value and other particulars and it is only after verification the octroi duty leviable is determined and amount is debited in the account current and the demand also is issued. The learned counsel for the appellant also referred to certain documents to show that for every category of arti cle	 the Company has given a distinctive number and the goods are easily identifiable and the number of items or quantity imported are all record in the register and com puterised for easy verification. It is these identifying numbers of the articles that are mentioned in the intima tion cure application for written permission for export. He also relied on the fact that the Company has no manufactur ing unit within the Thane Municipality. Similarly	 Column 6 of Form II also could not be complied with as it is not applicable to a person who is having current account facili ty. So far as the value is concerned the learned counsel for the appellants have fairly stated that the respondent was taking 72% of the list price of the articles for determining octroi payable	 for which he has no objection. In fact	 he has suggested that since the Company publishes the price list periodically and that which shows the current price at any point of time may be taken as the basis for such valua tion. The Octroi Exit Naka Officer had refused to give the certificate of export pass on the ground that the particu lars in Columns 5 and 6 of Form 11 could not be verified as the original invoices and the deposit receipts were not produced. Since these columns could be filled only to the extent possible by a person having an account current facil ity and there is no dispute about the export of the goods mentioned therein the refusal to give the export pass cer tificate. by the Exit Naka Officer could not be sustained. 471 The next point to be considered is the procedure to be followed when the importer wants to "breaking the hulk" and repack the goods in smaller quantities and also the proce dure relating to filling up Forms 11 and 12 and the refund applications in such circumstances. Rules 24 (2.) states that for breaking the bulk and repacking in smaller pack ages	 sanction of the Superintendent of Octroi is necessary and the "breaking bulk" shall also be done in the presence of an officer deputed for this purpose. Rule 62 of Chapter VIII of the Schedule to the Bombay Provincial Municipal Corporation Act	 1949 provides that subject to the standing orders not less than 90% of the octroi paid on any goods shall be refunded if such goods are exported beyond the limits of the city within six months of payment: "provided that. (C) in the case of goods which have been broken bulk prior intimation has been given to the officers specified in this behalf in the standing orders and the place or places of storage have been reported to him from time to time". Paragraph 5 of Appendix IV to this Act which we have noticed earlier states that the rules flamed under the Municipal Act shall "in so far as it is not inconsistent with the provisions of this Act	 continue in force". Rule 62 of Chapter VIII forms part of the Act. The learned counsel for the appellant	 therefore	 contended that Rule 62 shall prevail and prior intimation of the intention to 'breaking bulk ' shall be enough and there was no necessity for the Company to get the sanction of the Superintendent of Octroi or break the bulk in the presence of an officer deputed for the purpose as required under sub rule (2) of Rule 24. In other words according to the learned counsel Rule 24 (2) of the Octroi Rules is inconsistent with Rule 62 of Chapter VIII of the Schedule to the Act and to the extent. _ of inconsistency it shall be deemed to be not applicable. On the other hand the learned counsel for the respondent con tended that Rule 62 (c) deals with prior intimation and Rule 24 (2) deals with the sanction and breaking of the bulk in the presence of an officer deputed for that purpose and both the rules can stay together and operate and there is no inconsistency. We are not impressed with the argument that there is an inconsistency between Rule 62 and Rule 24 (2). The intimation contemplated in Rule 62 imply that the break ing the bulk shall be done with the knowledge of the octroi authorities. But it Cannot be said that the rules further provide that after intimation the breaking of the bulk shall be done in the presence of the officers and after sanction that would in any case be inconsistent. Both the rules thus can stand together. In H.M.M. Limited vs Administrator	 ; this Court had occasion to consider the effect of non com pliance with this require 472 ment of a similar provision	 on the right to get refund. Shortly stated the facts in that case were these: The appel lant brought into the municipal limits Horlicks in bulk containers (large steel drums) for being packed in unit containers (glass bottles) at the packing station in Banga lore and thereafter exported outside the municipal limits. In respect of the milkfood so exported in glass bottles the appellants sought refund of octroi on the ground that there was no consumption	 use or sale within the municipal limits and the goods were exported. Rule 24 of the Octroi Rules that were in force in Bangalore city provided: "24. 0n all articles on which octroi duty has been paid and which are subsequently exported beyond the octroi limits without breaking bulk	 refunds shall	 subject to the following rules	 be granted at the rate originally charged at the time of import; provided that no such refunds shall	 except in the ease of timber imported and re exported in log be granted unless such goods are exported within three months from the date on which octroi was levied". Relying on this provision it was contended by the Munic ipality that breaking the bulk amounted to "use" within the municipal limits attracting levy of octroi and no refund was permissible. The refund application had also not been made within three months from the date on which octroi was levied. It was admitted that the appellants had not followed that procedure prescribed in Rule 24. This Court held that mere transferring of a bulk product in small containers like packets or bottles for the purpose of sale does not amount to use of the goods in the sense the word is used in rela tion to levy of octroi. It was further held that the words "without breaking bulk" is not an expression of art and that meant only transferring the product from the drums by break ing the seal of the drums	 to the bottles for the purpose of exporting or for taking them out of the municipal limits	 and that would not amount to either use or consumption of the Horlicks powder within the municipal limits attracting the levy of octroi. The ratio of the judgment clearly is that merely on the ground that the goods are not exported in bulk as originally imported	 the levy does not become valid or that the import er who exported the goods loses his right to a refund of the octroi paid. The goods neither loose their identity nor cease to be identifiable. Once we reach the conclusion that there is no consumption or use	 octroi is not attracted and if any levy has been made and the amount collected	 the same becomes legally refundable even when the goods are exported in parts and in smaller packages. This is particu 473 larly so because in the case of goods not consumed or used within the octroi area but exported there is a constitution al bar for the levy of octroi. In this connection we may also refer to another decision reported in Municipal Committee	 Khurari vs Dhannalal Sethi & Ors.	 [1969] I SCR 166. The rules considered in that case also provided that an application for refund was to be made in the prescribed form and that the exporter after filling in the particulars had to present his application at the office appointed for that purpose. There were other rules which provided an elaborate procedure to be followed at the time of export of the goods. These rules related to the octroi officers satisfying himself that the goods brought for export agree with those mentioned in the application	 presentation of the claim within the prescribed time	 iden tifying of the goods exported with those imported and other matters. This Court held that: "these rules do provide a procedure which an exporter wishing to claim refund has to fol low. But the question is whether in a case where an exporter has not done so	 is he disentitled from claiming the refund. The real difficulty in the way of the appellant Commit tee is that though the rules lay down a proce dure which such an applicant has to follow	 they do not provide at the same time that an applicant for refund who has failed to follow the procedure laid down in r.r. 35 to 39 would be disentitled to claim the refund. In the absence of such a provision coupled with the categorical language of r. 27 giving a right to an exporter of dutiable goods to claim 7/8th of the duty paid on such goods on their import	 it becomes difficult to uphold the denial by the appellant Committee of the right of respondents 1 and 2 such a refund. We are	 therefore	 of the opinion that in the present state of the rules	 the appeal must fail though for reasons different from those given by the Board of Revenue and the High Court". It may be pertinent to mention that the Maharashtra Municipalities (Octroi) Rules	 1968 also do not contain any specific provision that an applicant for refund who has failed to follow the procedure would be disentitIed to claim the refund. It may be noted that the amount collected which is equivalent to the octroi duty payable on the goods	 on entry into the octroi limits while in detention in the warehouse is only as a deposit pending export of the goods. The other aspect is that once octroi is not leviable the deposit made by the importer pending export is in the nature of a trust and refundable in the event of the export of the goods. Further in a given set of facts	 whether the rules have been complied with will have 474 to be tested having regard to the nature of the particular transaction and whether the object of the procedure provided is otherwise fully satisfied. ` Rule 28 also merely states that the refund shall be admissible if all the conditions in sub rule 2 of that Rule are satisfied. The object of requiring intimation or sanction and presence of an officer when breaking the bulk in the scheme of octroi levy and refund is to ensure that dutiable goods do not escape the assessment and refunds are made only in respect of goods exported. In other words the whole requirement relates to the identification of the goods. In that sense if the same is otherwise complied with the right to refund cannot be denied. These rules cannot be read as enabling the municipality to levy and collect octroi even in cases where the goods have not been imported for consumption or use. As held by this Court in Kirpal Singh Duggal vs Municipal Board	 Ghaziabad	 ; the octroi rules are intended to regulate the system on which the refunds shall be allowed and paid. What are merely matters of procedure which the municipality was entitled to require compliance with in granting refund cannot be treated as condition precedent for the entitlement of the refund itself. The Constitution prohibits levy of tax except in accordance with law. When the goods are not imported for consumption or use within the octroi area the municipality ceases to have any constitutional right to levy octroi. If the goods therefore have merely entered into the octroi limits and passed out of the same no octroi duty is attracted. The concept of octroi as held by this Court in Burma Shell s case (supra) may include "the bringing in of goods in a local area so that the goods come to a repose there". It is this concept that is reflected in Rule 28 (2) Co) when it requires evidence that the goods were exported out of the octroi limits within a period of six months of their im ports. The learned counsel for the appellants Mr. Andharuji na had expressed certain difficulties in satisfying the Corporation that the goods imported were exported within the period of six months as provided in the rules in view of certain peculiar circumstances in this case. He pointed out the goods received in bulk are small small items and there are about 16000 distinctive types of articles and when the bulks are broken and each of the categories items are mixed up together it becomes difficult for him to individually identify when the goods were received and when they were exported. However	 he was sure that the goods were exported before six months. When this difficulty was pointed out during the pendency of the appeal	 as an interim direction this Court by Order dated 1.5. 1989 directed the parties to proceed on the basis that the goods which came in first had gone out first unless some factors or features indicate otherwise. This is not equitable principle unknown to law. Even as early as in 1816 with reference to money paid on account to a creditor	 in Clayton 's case (1814) 475 23 All. E.R. Rep. P. 1	 it was held that in the absence of an agreement to the contrary	 in the case of current account containing debit and credit entries there is a presumption that the first item on the credit side of the account is intended to be applied in the payment of the first item on the debit side of the account. This is an equitable princi ple which could be followed in the instant case and it may be presumed that the goods which came in first have gone out first and the six months period could be determined on that basis. In any case in view of the interim direction given by this Court on May 1	1989 that may be usefully be followed for the future also in this case. To sum up: Having regard to the nature and incidence of octroi unless the octroiable goods are consumed or used or are meant to reach an ultimate user or consumer in the octroi area no octroi is leviable. The words 'sale therein in the words "consumption	 use or sale therein in the defi nition octroi means sale of octroiable goods to a person for the purpose of consumption or use by such person in the octroi area. If sale was intended for consumption or use in the octroi area whether the purchaser actually consumed inside or outside octroi area is irrelevant. Rules 24 to 30 and the forms in the system of levy of octroi are intended to regulate the procedure for collection	 identification of dutiable goods and correlation of goods exported with the goods imported for the purpose of refunds of octroi collect ed. In view of constitutional bar octroi is not leviable if the goods are not brought into the octroi area for purposes of consumption or use in the area but for export and in fact exported by the importer himself or the sale by him occa sions the export. Compliance with the procedure prescribed in the Rules for filing claims of refunds are not condition precedent for the right or eligibility for refund or the liability to refund but are provisions regarding proof of export of the goods imported and are not meant to be exhaus tive either. They are to be interpreted and understood in that sense. The object of the Rules fixing a period of limitation for export however is different. The export cannot be put in perpetual doubt and the goods may be con sidered to have come to a repose if they were not exported within a particular period provided in the rules. Applying these principles to the instant case	 on facts the rejection of refund applications on the ground that Rule 25 (3) (d) had not been complied with was illegal. Since the rejection of the claims for refund was merely on the ground that either Form 4 and original invoices were not produced or columns 5 and 6 of Form 11 or the corresponding columns in Form 12 had not been filled with reference to an original invoice or Form 4 or deposit receipt and the refusal to issue export pass certificates on those very grounds which we have stated are untenable the other orders of rejections are also invalid. If the goods are mixed up and unidentifia ble 476 due to breaking bulk and repacking in smaller and assorted packages before export the principle that the first export was of the goods first imported	 subject to any evidence available to the contrary	 may be applied and the six months period prescribed for export may be determined accordingly. When these appeals were pending by way of interim ar rangement this Court by order dated 25.4.1990 directed that in order to obviate the difficulty of identifying the goods at the time of export by reason of the breaking of the)bulk and in order avoid doubts	 the respondent Corporation may depute their officer or officers on all working days at the warehouse of the Company to supervise the breaking of the bulk subject to the Company reimbursing the entire monthly payments and other allowances to be paid to the said officer or officers as per bill or pay slips sent by the Corporation to the Company. We think that this procedure could be con tinued and followed in future also so that while the pur poses of the rules are served the free trade and commerce of the Company which is stated to have a large turnover is also not affected. The learned counsel for the respondent then contended that the appellants have recovered the amounts paid by them by way of octroi duty from the dealers or the customers to whom they had sold the goods and therefore they are in any case not entitled to get a refund. The argument was that if refund is ordered it would amount to allowing the appellants to unjustly enrich themselves at the cost of the public to whom the burden had already been passed. This argument is based on the ground that in the selling price the company had merged the octroi duty originally paid as deposit and if a refund is made the company would be getting an additional amount over and above normal price which they would have charged but for the fact that they were initially asked to deposit octroi. There is no evidence that any of the arti cles sold by the Company is subject to any price control by the Government or that the Company had charged any octroi separately in the bills	 Invoices and the other documents of sale to the outside purchasers produced before us do not also show that any octroi was separately charged and col lected by the Company. It may be mentioned that in the rejoinder filed by the appellant in the writ petition they have specifically denied that they "have recovered the amount paid by them by way of octroi duty from the dealers to whom they had sold the goods or that the dealers in turn have recovered the octroi duty from the customers". In view of this the question of unjust enrichment does not arise. 477 This appeal is accordingly allowed on the above terms. There will 'however be no order as to costs. T.N.A. Appeal allowed.

The appellant company was carrying on business of manu facture and sale of motor vehicles	 spare parts of motor vehicles and excavators. Their manufacturing units were located outside the municipal limits of the respondent corporation. Pursuant to the permission granted by the Respondent Corporation under Rule 10(2) of 446 the Maharashtra Municipalities (Octroi) Rules	 1968 the appellant company was maintaining a bonded warehouse within the municipal limits of the Respondent Corporation. The motor vehicles parts and excavators parts brought from the Company 's own factories as well parts imported from abroad were stored in this warehouse. These products were brought in bulk and thereafter taken or sent out from the Municipal limits in smaller packings depending on the requirements of the customers in various parts of the country. The appellants were also granted current account facilities without the requirement of immediate payment of octroi at the Octroi Naka. Accordingly	 the appellants were carrying out their activities of imports and exports under the current account procedure with facility of unpacking the bulk	 repacking and exporting. Under the Octroi Rules the octroi becomes refundable when the goods in respect of which octroi was paid are exported out of octroi limits within 6 months of their im port. During the period 1st January	 1983 to 31st March	 1984 the appellant Company made 1182 claims for refund of octroi which were rejected by the Corporation on the grounds: (1) the Company had "sold" the spare parts within the octroi limits of the Corporation in contravention of Rule 25(3) (d) of the Maharashtra Municipalities (Octroi) Rules	 1968; (2) the procedure prescribed for export and the claim of refund had not been strictly followed. The appellants filed a writ petition under Article 226 in the High Court of Bombay contending that the action of the Municipal Corporation in refusing refund was unconstitu tional and illegal. The Division Bench of the High Court dismissed the writ petition. The Company filed an appeal in this Court against the decision of the High Court. In appeal to this Court it was contended on behalf of the appellant (i) since the sales were not for consumption or use within the octroi limits and that the parts were sold to parties outside the octroi limits and also for consump tion or use outside such limits the rejection of the claims by the Respondent Corporation on the ground that the sales were within the municipal limits in contravention of rule 25(3) (d) of the Rules is illegal; (ii) Under Rule 62 of Chapter VIII of the Schedule to Bombay Provincial Municipal Corporation Act	 1949	 prior intimation of the intention to 'break the bulk ' is enough and there is no necessity for the company to get the sanction 447 of Superintendent of Octroi or break the bulk in the presence of an officer deputed for the purpose as required under sub rule (2) of Rule 24 of the Maharashtra Municipali ties (Octroi) Rules	 1968; Rule 24(2) of the Octroi Rules is inconsistent with Rule 62 and to the extent of inconsistency it shall be deemed to be not applicable. On behalf of the respondent Corporation it was contended (i) that the meaning of words "sales therein" in the defini tion of octroi in the Acts and in Entry 52 of List II of VII Schedule to the Constitution could not be limited to sales of the goods for purposes of consumption or use within the municipal limits; (ii) there was a change in the ownership of the goods since a sale in law had taken inside the octroi limits though the purchaser was residing and carrying on business outside the octroi limits and under the sale the goods were intended to be and in fact exported for the purpose of consumption and use outside the octroi limits; (iii) that while Rule 62 (c) deals with prior intimation Rule 24(2) deals with the sanction and breaking of the bulk in the presence of an officer deputed for that purpose and both the rules can stay together and operate and there is no inconsistency; (iv) since the appellants have recovered the amounts paid by them by way of octroi duty from their deal ers or customers they are not entitled to refund; ordering of refund would amount to allowing the appellants to unjust ly enrich themselves at the cost of the public to whom the burden had already been passed. Allowing the appeal	 this Court	 HELD: 1. In the case of impost of octroi the taxable event is the entry of goods which are meant to reach an ultimate user or consumer in the area. Mere physical entry into the octroi limits would not attract levy of octroi. When the goods are brought in not for consumption within the area but for temporary detention and eventual export	 octroi is not leviable. The octroiable event in such a case shall be deemed not to have happened. This is particularly so because in the case of goods not consumed or used within the octroi area but exported there is a constitutional bar for the levy of octroi. In view of the constitutional bar	 octroi is not leviable if the goods are not brought into the octroi area for purposes of consumption or use in the area but for export and in fact exported by the importer himself or the sale by him occasions the export. [458 B C	 472 H	 473 A	 475 E] 1.1 Having regard to the nature and incidence of octroi unless the octroiable goods are consumed or used or are meant to reach an 448 ultimate user or consumer in the octroi area no octroi is leviable. The words 'sale therein ' in the words 'consump tion	 use or sale therein ' in the definition octroi means sale of octroiable goods to a person for the purpose of consumption or use by such person in the octroi area. If sale was intended for consumption or use in the octroi area whether the purchaser actually consumed inside or outside octroi area is irrelevant. Therefore octroi rules cannot be read as enabling the municipality to levy and collect octroi even in cases where the goods have not been imported for consumption or use.

Ltd. vs Administrator	 ; 	 relied on. Khandelwal Traders Akola vs The Akola Municipal Council	 AIR 1985 Born. 218	 approved. 1.2 Since the goods were sold by the Company to outside purchasers and the goods under the transactions of sale were intended to be exported and were in fact exported	 for consumption or use outside the municipal limits no octroi duty was leviable and the octroi duty paid on entry into the municipal limits was	 therefore	 liable to be refunded. Accordingly the rejection of the refund claims on the ground that Rule 25(3) (d) had not been strictly complied with is illegal and could not be sustained. [457 G H] 2. Once octroi is not leviable the deposit made by the importer pending export is in the nature of a trust and refundable in the event of the export of the goods. [473 G H] 2.1 Under the octroi scheme	 when the goods in respect of which octroi is paid are exported	 the octroi becomes refundable. Right to refund arises because the goods are not consumed inside the area but exported and the tax becomes not leviable. [458 C] 2.2 If there is no consumption or use	 octroi is not attracted and if any levy has been made and the amount collected	 the same becomes legally refundable even when the goods are exported in parts and in smaller packages. [472 H] 3. The rules merely regulate the system on which refund shall 449 be allowed. In a given set of facts	 whether the rules have been complied with will have to be tested having regard to the nature of the particular transaction and whether the object of the procedure provided is otherwise fully satis fied. [458 D	 473 H	 474 A] 3.1 The object of requiring intimation or sanction and presence of an officer when breaking the bulk in the scheme of octroi levy and refund is to ensure that dutiable goods do not escape the assessment and refunds are made only in respect of goods exported. In other words the whole require ment relates to the identification of the goods. In that sense if the same is otherwise complied with the right to refund cannot be denied. [474 A B] 3.2 Rules 24 to 30 of the Maharashtra Municipalities (Octroi) Rules	 1968 and the forms in the system of levy of Octroi are intended to regulate the procedure for collection identification of dutiable goods and correlation of goods exported with the goods imported for the purpose of refunds of octroi collected. [475 D] The rules do not contain any specific provision that an applicant for refund who has failed to follow the procedure would be disentitled to claim the refund. [473 G] 3.3 Compliance with the procedure prescribed in the Rules for filing claims of refunds are not conditions prece dent for the right or eligibility for refund or the liabili ty to refund but are provisions regarding proof of export of the goods imported and are not meant to be exhaustive ei ther. They are to be interpreted and understood in that sense. [475 E F] Municipal Committee Khurari vs Dhannalal Nethi & Ors.	 ; ; Kirpal Singh Duggal vs Municipal Board	 Ghaziabad	 ; 	 applied. 3.4 Since the rejection of the claims for refund was merely on the ground that either form 4 and original in voices were not produced or columns 5 and 6 of Form 11 or the corresponding columns in Form 12 had not been filled with reference to an original invoice or Form 4 or deposit receipt and the refusal to issue export pass certificates on those very grounds are untenable the orders of rejection are invalid. 1475 G H] 4. The object of the Rules fixing a period of limitation for 450 export however is different. The export cannot be put in perpetual doubt and the goods may be considered to have come to a repose if they were not exported within a particular period provided in the rules. [475 F] 4.1 However an equitable principle could be followed in this regard and it may be presumed that the goods which came in first have gone out first. If the goods are mixed up and unidentifiable due to breaking bulk and repacking in smaller and assorted packages before export the principle that the first export was of the goods first imported	 subject to any evidence available to the contrary	 may be applied and the six months period prescribed under Rule 28(2) (b) for export may be determined accordingly. [475 A B	 H	 476 A] Clayton 's case; 	 	 applied. There is no inconsistency between Rule 62 and Rule 24(2). The intimation contemplated in Rule 62 imply that the breaking the bulk shall be done with the knowledge of the octroi authorities. But it cannot be said that the rules further provide that after intimation the breaking of the bulk shall be done in the presence of the officers and after sanction that would in any case be inconsistent. Therefore	 both the rules can stand together. [471 F G] 6. There in no evidence that any of the articles sold by the Company is subject to any price control by the Gov ernment or that the Company had charged any octroi separate ly in the bills. Documentary evidence do not also show that any octroi was separately charged and collected by the Company. Therefore the question of unjust enrichment does not arise. [476 F H]
