The Judgment of the Court was delivered by BHAGWATI	 J. This appeal by special leave raises two questions relating to the interpretation of certain provisions of the Bombay Municipal Boroughs Act	 1925. The facts giving rise to the appeal are few and may be briefly stated as follows: The respondents are rate payers liable to pay property tax in respect of their lands and buildings situate within the limits of the erstwhile Municipal Borough of Dharwar now converted into the Hubli Dharwar Municipal Corporation. The Municipal Borough of Dharwar (hereinafter referred to as the Municipal Borough) was at the material time governed by the provisions of the Bombay Municipal Boroughs Act	 1925 (hereinafter referred to as the Act). The Chief Officer of the Municipal Borough prepared an assessment list for the official year 1951 52 containing revised valuation and assessment of the lands and buildings situated within the limits of the Municipal Borough and published it on 1st May	 1951 in accordance with the provisions of the Act. The respondents and several other rate payers filed their objections against the valuation and assessment in the assessment list and consequent on the decisions on the objections	 modifications were made in the assessment list and the assessment list so finalised was authenticated on 24th July	 1952. Since the authentication of the assessment list was made after the expiry of the official year	 the respondents and other rate payers took the view that the assessment list was void and inoperative and the Municipal Borough was not entitled to recover property tax at the revised rates which were higher than the rates charged in the previous official years. It seems	 however	 that from a few persons	 whose names do not appear in the record property tax in accordance with the revised rates was collected by the Municipal Borough. There was consequently an agitation amongst the rate payers and a body called the Citizens Welfare Association championing the causes of the rate payers addressed a communication dated 30th November	 1952 to the Director of Local Authorities requesting him to direct the Municipal Borough to refund the excess amount of property tax collected from the rate payers	 because according to them the levy and collection of property 886 tax at the revised rates was illegal in view of the fact that the assessment list was authenticated only on 24th July	 1952 beyond the expiration of the official year for which the property tax was sought to be levied. The Director of Local Authorities by his reply dated 16th December	 1952 informed the Citizens Welfare Association that the levy of property tax under the authenticated assessment list was	 according to him	 perfectly valid. The President of the Municipal Borough thereafter issued a public notice dated 10th November	 1954 calling upon the rate payers to "pay immediately all the tax still due from them and extend their full cooperation to the Municipal Borough". Since the Municipal Borough was determined to recover the amount of property tax from the rate payers at the enhanced rates appearing in the assessment list	 the respondents	 acting for and on behalf of themselves and other rate payers	 filed a suit against the Municipal Borough on 6th June	 1955. after giving notice dated 1st April	 1955 on the hypothesis that such notice was required to be given under s 206A of the Act. The main reliefs claimed in the suit were	 firstly	 a declaration that the Municipal Borough was not entitled to recover property tax from the rate payers at the revised rates since the assessment list was authenticated beyond the expiration of the official year and secondly	 an order directing the Municipal Borough to refund the excess property tax recovered by it from the rate payers. The Municipal Borough in its written statement raised a preliminary objection that the suit was barred by limitation since it was not filed within six months of the accrual of the cause of action as required by section 206A of the Act and it also disputed the claim of the rate payers on merits on the ground that there was nothing in the Act which required that the assessment list should be authenticated before the expiration of the official year and that even if the assessment list was authenticated beyond the expiration of the official year	 it did not have the effect of invalidating the assessment list. The Trial Court negatived the plea of limitation based on section 206A of the Act and so far as the merits were concerned	 held that since the authentication of the assessment list was admittedly made beyond the expiry of the official year	 the assessment list was void and inoperative and the Municipal Borough was not entitled to levy and collect property tax at the revised rates on the strength of such assessment list. The Municipal Borough	 being aggrieved by this decision	 filed an appeal to the District Court	 but the appeal was unsuccessful and a second appeal to the High Court also failed. Hence the present appeal by the Municipal Borough with special leave obtained from this Court. The principal contention that was urged before us on behalf of the Municipal Borough was that on a true construction of the relevant provisions of the Act	 the authentication of the assessment list	 in client to impose liability to tax for the official year even if it is made the official year to which the assessment list relates and it is sufficient to impose liability to tax for the official year even if it is made at any time after the expiry of the official year and	 therefore	 in the present case	 though the authentication of the assessment list for the official year 1951 52 was made on 24th July	 1952 after the expiry of 887 the official year	 it was valid and effective and operated to create liability on the tax payers for payment of tax at the revised rates. In order to appreciate this contention it is necessary to examine briefly the scheme of the Act in regard to assessment and levy of property tax. The tascicunus or section from 78 to 89 deals with assessment of and liability to rates of buildings and lands. These sections set out the procedure which must be followed for levy of rates on buildings and lands. Section 78	 sub section (1) requires the Chief Officer to cause an assessment list of all lands and buildings in the Municipal Borough to be prepared containing various particulars set out in the section. When the preparation of the assessment list is completed	 the Chief Officer is required under section 80 to give public notice of the list and of the place where the list or a copy thereof could be inspected. Simultaneously the Chief Officer has also to give public notice under sub section (1) of section 81 of a date not less than one month after such publication before which objections to the valuation or assessment in such list shall be made. Sub section (2) provides for the mode in which the objections must be made and sub section (3) provides for the hearing and disposal of the objections by the Standing Committee and the proviso to this sub section permits the powers and duties of the Standing Committee to be transferred to another committee or to any officer of the government. This sub section provides that before the objections are investigated and disposed of	 the objector shall be given an opportunity of being heard in person or by an agent and it is only after the hearing the objectors that the objections can be disposed of. When the objections are thus considered and disposed of	 the assessment list with the modifications which may have been made consequent upon the decisions on the objections has to be authenticated in the manner set out in sub section Sub section (5) provides that the list so authenticated shall be deposited in the Municipal office and shall be open for inspection during office hours to all rate payers. The completion of this procedure leads to certain important consequences and they are set out in sub section (6) which reads as follows: "(6) Subject to such alterations as may be made therein under the provisions of section 82 and to the result of any appeal or revision made under sec. 110	 the entries in the assessment list so authenticated and deposited and the entries	 if any	 inserted in the said list under the provisions of sec. 82 shall be accepted as conclusive evidence (1) . (ii) for the purposes of the rate for which such assessment list has been prepared	 of the amount of the rate liable on such buildings or lands or both buildings and land in any official year in which such list is in force. " section 82 then provides for amendment of assessment list in certain cases. This section is rather material and it may be reproduced in full: "82. (1) The standing committee may at any time alter the assessment list by inserting or altering an entry in respect of any property	 such entry having been omitted from or 888 erroneously made in the assessment list through fraud	 accident or mistake or in respect of any building constructed altered	 added to or reconstructed in whole or in part	 where such construction	 alteration	 addition or reconstruction had been completed after the preparation of the assessment list	 after giving notice to any person interested in the alteration of the list of a date	 not less than one month from the date of service of such notice	 before which any objection to the alteration should be made. (2) An objection made by any person interested in any such alteration	 before the time fixed in such notice	 and in the manner provided by sub section (2) of section 81	 shall be dealt with in all respects as if it were an application under the said section. (3) An entry or alteration made under this section shall subject to the provisions of section 110	 have the same effect as if it had been made in the case of a building constructed altered	 added to or reconstructed on the day on which such construction	 alteration	 addition or reconstruction was completed or on the day on which the new construction	 alteration	 addition or reconstruction was first occupied	 whichever first occurs	 or in other cases	 on the earliest day in the current official year on which the circumstances justifying the entry or alteration existed; and the tax or the enhanced tax as the case may be shall be levied in such year in the proportion which the remainder of the year after such day bears to the whole year. " The next important section is section 84 which provides for the adoption of valuation and assessment contained in the assessment list of any particular year for the year immediately following. That section is in the following terms: "84. (1) It shall not be necessary to prepare a new assessment list every year. Subject to the condition that every part of the assessment list shall be completely revised not less than once in every four years	 the Chief Officer may adopt the valuation and assessment contained in the list for any year	 with such alterations as may be deemed necessary	 for the year immediately following. (2) But the provisions of sections 80	 81 and 82 shall be applicable every year as if a new assessment list had been completed at the commencement of the official year. " The other sections in this group are not material and it is not necessary to refer to them. It is clear from the scheme of these provisions that the official year is the unit of time for the levy of the tax. The provisional assessment list is prepared for the official year. This may be done before the commencement of the official year or even thereafter in the course of the official year. Then objections are invited and when made	 they are disposed of and amendments consequential upon the 889 decisions on the objections are carried out in the assessment list. The assessment list is then authenticated. The process of assessment and levy of the tax which begins with the preparation of the provisional assessment list is thus completed when the assessment list is authenticated. The assessment list	 when authenticated	 becomes effective from the first day of the official year and gives rise to the liability to pay tax. It is on the authentication of the assessment list that the liability of the rate payers to pay tax arises and the tax is levied on the rate payers. This position would seem to be clear as a matter of plain interpretation and in any event there is a long line of decisions of the Bombay High Court commencing from Sholapur Municipality vs Governor General(1) and ending has Sholapur Municipal Corporation vs Ramchandra(2) which has consistently accepted this position and the learned counsel appearing on behalf of the Municipal Borough did not dispute the correctness of these decisions. The only contention raised by him was as to within what time the assessment list must be authenticated	 if it is to be a valid and effective assessment list. It is to this contention that we must now address ourselves. Now	 once we take the view that the process of levying the tax is complete only when the assessment list is authenticated and it is only then that the tax is levied on the rate payers	 it is difficult to resist the conclusion that the authentication must be made within the official year. The tax	 being a tax for the official year	 must obviously be levied during the official year and since the levy of the tax is complete only when the assessment list is authenticated	 it must follow a fortiori that the authentication on the making of which alone the levy of the tax is effected	 must take place in the official year. Any other view would result in an anomalous and rather absurd situation	 namely	 that the tax for an official year would be leviable at any time	 even years after the expiration of the official year. That could not possibly have been intended by the legislature. That would indeed be a strange consequence in case of a tax which is annual in its structure and organisation and which is intended to be levied for each official year. But	 apart from this consideration	 there is inherent evidence in the sections themselves which shows that the authentication was intended by the legislature to be a step which must be taken before the close of the official year. Section 84 provides that it shall not be necessary to prepare a new assessment list every year but	 subject to the conditions that every part of the assessment list shall be completely revised not less than once in every four years	 the Chief Officer may adopt the valuation and assessment contained in the list for any year	 with such alterations as may be deemed necessary	 for the year immediately following. This provision postulates that there would be an assessment list for each official year at the close of that official year	 so that the valuation and assessment contained in it can be adopted by the Chief Officer for the immediately following year. Now clearly the assessment list which can be adopted for the immediately following year 890 is the authenticated assessment list and it would	 therefore	 seem that the legislative assumption underlying this provision is that in respect or each official year	 there would be an authenticated assessment list before the close of that official year	 so that the valuation and assessment contained in it can be adopted by the Chief Officer for the immediately following year. Otherwise	 it would not be possible for the Chief Officer to adopt the valuation and assessment of the preceding official year and he would have to prepare a new provisional assessment list every time when the assessment list for the preceding year is not finalised and authenticated and this might lead to the rather startling result of there being several provisional assessment lists for different official years in the process of finalisation at the same time. We should be slow to accept an interpretation which might lead to such a strange consequence. Then again considerable light on this question is thrown by the provision enacted in section 82. It is a well settled rule of interpretation that the Court is "entitled and indeed bound	 when construing the terms of any provision found in a statute	 to consider any other parts of the Act which throw light on the intention of the legislature	 and which may serve to show that the particular provision ought not to be construed as it would be alone and apart from the rest of the Act. " The statute must be read as a whole and every provision in the statute must be construed with reference to the context and other clauses in the statute so as	 as far as possible	 to make a consistent enactment of the whole statute. Obviously	 therefore	 section 78 to 81 must be so construed as to harmonise with section 82. They must be read together so as to form part of a connected whole. Section 82	 sub section (1) provides for making of an amendment in the assessment list by insertion or alteration of an entry in certain events after hearing objections which may be made by any person interested in opposing the amendment. Sub section (3) of section 82 makes the amendment effective from "the earliest day in the current official year on which the circumstances justifying the entry or alteration existed. " The expression 'current official year ' in the context in which it occurs in section 82	 sub section (3) clearly signifies the earliest day in the official year which is current when the amendment in the assessment list takes place and that expression refers only to the official year which is running at the time when the amendment is made by insertion or alteration of an entry under sub section (1) of section 82. It would	 therefore	 seem clear	 on a combined reading of sub sections (1) and (3) of section 82	 that an amendment	 in order to be effective in levying tax for an official year	 must be made during the currency of the official year. That is now well settled as a result of several decisions of the Bombay High Court culminating in the Full Bench decision in Sholapur Municipal Corporation vs Ramchandra (supra) and we do not see any reason to take a different view. Now the scheme of sections 78 to 81 is identical with that of section 82 and in both cases what is contemplated first is a proposal to which objections are invited and after the objections are investigated and disposed of	 the assessment list in the one case and the altered entry in the other are authenticated giving rise to liability in the rate payer. It must follow a fortiori that if an alteration in the assessment list	 in order 891 to fasten liability on the rate payer	 is required to be made during the currency of the official year	 equally	 on a parity of reasoning	 the assessment list	 in order to give rise to liability in the rate payer	 must also be authenticated before the expiry of the official year. Moreover	 it is difficult to behave that the legislature did not intend that there should be any time limit in regard to the levy of tax for an official year and that the tax should be legally leviable at any time after the close of the official year. There is	 in our opinion	 sufficient indication in the various provisions of the Act to show that the authentication of the assessment list	 in order to be valid and effective	 must be made within the official year	 though the tax so levied may be collected and recovered even after the expiry of the official year. We may point out that the Karnataka High Court is not alone in taking this view the present case. This view has been consistently taken by the Bombay High Court in a series of decisions over the years and it has also been followed by the Gujarat High Court. When we find that three High Courts having jurisdiction over the territories in which the Act is in force have all taken this view over a course of years	 we do not think we would be justified in departing from it	 merely on the ground that a different view is possible. This Court is ordinarily loathe to interfere with the interpretation of a State statute which has prevailed in the State for a long number of years and which the State Legislature has chosen not to disturb by legislative amendment. As a matter of fact	 we find that	 in the present case	 the Bombay Legislature accepted this interpretation of sections 78 to 81 and gave legislative recognition to it by introducing section 84A by Bombay Act 53 of 1954. That section provides that where in any year a new assessment list is prepared	 or a list is revised	 or the valuation and assessment contained in the list for the year immediately preceding is adopted with or without alteration	 such new	 revised or adopted assessment list shall be authenticated in the manner provided by section 81 at any time not later than the thirty first day of July of the official year to which the list relates	 and if it is not so authenticated	 then the State Government shall appoint such person or persons as it thinks fit to prepare	 revise or adopt and authenticate the assessment list	 and thereupon such person or persons shall duly authenticate such list at any time before the last day of the official year to which such list relates	 and sections 78 to 81 or section 84 shall	 as far as may be	 apply to the preparation	 revision or adoption of the list	 as the case may be	 by the person or persons appointed by the State Government. It is clear from this provision that the Legislature not only did not amend the Act for the purpose of removing the time limit of the official year or enlarging such time limit	 but on the contrary	 made the time limit more stringent by providing that the authentication shall be made by the Municipal Borough not later than 31st July of the official year and if the authentication is not made within that time	 the State Government shall be entitled to appoint a person for the purpose of authenticating the assessment list and the authentication by such person shall not. in any event	 be later than the last day of the official year. We are	 therefore	 of the view that the assessment list	 in order to be effective in levying the tax	 not be authenticated before the expiry of the official year and if it is not	 the assessment list would be void and inoperative and not give rise to liability in the rate payers to pay tax. 892 That takes us to the second contention urged on behalf of the Municipal Borough based on section 206A. That section provides inter alia that no suit shall lie against a municipality or against any officer or servant of any municipality in respect of any act done in pursuance or execution or intended execution of the Act	 or in respect of any alleged neglect or default in the execution of the Act	 unless it is commenced within six months next after the accrual of the cause of action. The argument of the Municipal Borough was that the cause of action for the suit arose in favour of the respondents and other rate payers on 24th July	 1952 when the assessment list was authenticated and since the suit was not filed within six months from that date	 it was barred by limitation under s.206A. This argument is plainly unsustainable. The assessment list being authenticated on 24th July	 1952	 after the expiry of the official year 1951 52	 was void and inoperative and the respondents and other rate payers were entitled to ignore it as a nullity. It is only when the Municipal Borough sought to recover the amount of tax from them on the strength of the assessment list	 that it became necessary for them to challenge the validity of the assessment list with a view to resisting the demand of the Municipal Borough. Then and then only could a cause of action be said to have accrued to them which they were required to enforce within a period of six months. Now	 in the present case	 there is no material to show as to when notices of demand requiring the respondents and other rate payers to pay the amount of tax were issued by the Municipal Borough or which rate payers paid the amount of tax and when. It is not possible to say	 in the absence of such material	 as to when the cause of action for filing the suit arose to the respondents and other rate payers and whether it arose within six months before the filing of the suit or at a point of time earlier than that. The Municipal Borough cannot	 in the circumstances	 be held to have established that the suit was not commenced by the respondents and other rate payers within six months after the accrual of the cause of action and the plea of limitation based on section 206A must fail. We are	 therefore	 of the view that there is no substance in the appeal and it must be dismissed	 but in the peculiar circumstances of the case	 we make no order as to costs. V.P.S. Appeal dismissed.

The scheme of Ss. 78 to 84 of the Bombay Municipal Boroughs Act	 1925	 shows that the official year is the unit of time for the levy of rates on buildings and lands. Under these provisions the provisional assessment list is prepared for the official year	 either before the commencement or in the course of the official year	 objections are invited	 and amendments consequential upon the decisions on the objections are carried out in the list. The assessment list is then authenticated. The process of assessment and levy of tax which begins with the preparation of the provisional assessment list is thus completed when the assessment list is authenticated. The assessment list	 when authenticated	 becomes effective from the first day of the official year and gives rise to the liability or the rate payers to pay the tax levied. [889 C] For the assessment year 1951 52	 the appellant followed the procedure but the authentication was on July 24	 1952	 after the expiry of the official year on March 31	 1952. Since property tax in accordance with the revised rates was sought to be levied	 the respondents filed a suit for a declaration that the appellant was not entitled to recover any property tax at the revised rates. The suit was decreed and the decree was affirmed by the High Court. In appeal to this Court	 it was contended that	 (1) the authentication of the assessment list in order to be valid and effective	 need not be made before the expiry of the official year to which the assessment list relates; and (2) the suit was barred under section 206A of the Act. Dismissing the appeal	 ^ HELD: (1) The assessment list in order to be effective in levying the tax must be authenticated before the expiry of the official year and if it is not	 the assessment list would be void and inoperative and would not give rise to any liability in the rate payers to pay tax. [891 H] (a) Once the view is taken that the process of levying the tax is complete only when the assessment list is authenticated and it is only then that the tax is levied on the rate payers	 it follows that the authentication must be made within the official year. The tax being a tax for the official year must obviously be levied during the official year and since the levy of tax is complete only when the assessment list is authenticated it must follow a fortiori that the authentication must take place in the official year. Otherwise	 the tax for an official year would be leviable at any time	 without any time limit	 even years after the expiration of the official year	 which could not have been the intention of the legislature	 since it is an annual tax intended to be levied for each official year. [889 D F] (b) Section 84 provides that it shall not be necessary to prepare a new assessment list every year but subject to the condition of revision once in every four years	 the Chief Officer may adopt the assessment list for any year	 with necessary alterations for the year immediately following. The provision 884 postulates that there would be an assessment list	 that is	 the authenticated assessment list	 for each official year before the close of that official year so that it can be adopted by the Chief Officer for the immediately following year. Otherwise	 he would have to prepare a new provisional assessment list every time when the Assessment List for the preceding year is not finalised and authenticated	 and this might lead to the starting result of there being more than one provisional assessment list in the process of finalisation at the same time. [889 G 890 C] (c) In interpreting a provision of a statute the court is entitled and indeed bound to consider any other parts of the Act which throw light on the intention of the legislature. The statute must	 therefore	 be read as a whole and every provision in it must be construed with reference to the context and other clauses so as	 as far as possible	 to make a consistent enactment of the whole statute. Section 82(1) provides for making of an amendment in the assessment list by insertion or alteration of an entry in certain events	 after hearing any objections to the amendment	 Section 82(3) makes the amendment effective from 'the earliest day in the current official year in which the circumstances justifying the entry or alteration existed. ' The expression clearly signifies the earliest day in the official year which is current when the amendment in the assessment list takes place	 that is	 the official year which is running at the time when the amendment is made by insertion or alteration of an entry. Therefore	 a combined reading of section 82(1) and (3) shows that an amendment	 in order to be effective in levying tax for an official year	 must be made during the currency of the official year. The scheme of sections 78 to 81 is identical with section 82 and in both cases what is contemplated first is a proposal to which objections are invited and after the objections are investigated and disposed of	 the assessment list in one case	 and the altered entry in the other	 are authenticated	 giving rise to liability in the rate payer. It must follow a fortiori that if an alteration in the assessment list in order to fasten liability on the rate payer	 is required to be made during the currency of the official year equally	 the assessment list	 in order to give rise to liability in the rate payer	 must also be authenticated before the expiry of the official year. [890 C 891 B] Sholapur Municipality vs Governor General	 49 Bom. L.R. 752 and Sholapur Municipal Corporation vs Ramchandra 74 Bom. L.R. 489 referred to. (d) Three High Courts having jurisdiction over the territories in which the Act is in force have all taken this view over a course of years and this Court will not be justified in departing from it	 merely on the ground that a different view is possible. This Court is ordinarily loathe to interfere with the interpretation of a State statute which has prevailed in the State for a long number of years and which the State Legislature has chosen not to disturb by legislative amendment. [891 C D] (e) In the present case	 the Bombay Legislature has accepted the interpretation of sections 78 to 81 by the three High Courts and given legislative recognition to it by introducing section 84A by Bombay Act 53 of 1954. This provision makes it clear that the legislature not only did not amend the Act for the purpose of removing the time limit of the official year as interpreted by the High Courts or enlarging such time limit	 but on the contrary	 made the time limit more stringent by providing that the authentication shall be made by the Municipal Borough not late than July 31	 of the official year	 and that if the authentication is not made within that time	 the State Government shall be entitled to appoint a person for the purpose of authenticating the assessment list and that the authentication by such person shall not	 in any event	 be later than the last day of the official year. [891 D H] (2) Section 206A provides	 inter alia	 that no suit shall lie against a municipality in respect of any act done in pursuance of execution or intended execution of the Act unless it is commenced within 6 months next after the accrual of the cause of action. It could not	 however	 be contended that the cause of action for the suit in the present case arose in favour of the respondents and other rate payers on July 24	 1952	 when the list was authenticated and that the suit	 not having been filed within 6 months of that date	 is barred. The assessment list in the present case was authenticated after the expiry of 885 the official year and was void and inoperative and the respondents and other rate payers were entitled to ignore it as a nullity. Their cause of action arose only when the appellant sought to recover the amount of tax from them on the strength of that assessment list. In the absence of material to show when the notices demand requiring the respondents and other rate payers to pay the amount of tax were issued	 or which rate payers paid and when it is not possible to say whether the cause of action for filing the suit arose to the respondents within six months before the filing of the suit or earlier.
