Summarize the following court judgment. ivil Appeals No. 1619 to 1622 of 1971. Appeals by Special Leave from the Award dated the 27th November	 1970 of the Industrial Court	 Maharashtra (Nagpur Bench) Nagpur in References (I.C.N.) Nos. 13	 14	 15	 and 19 of 1969 communicated to the parties on 14 1 1971. M.K. Ramamurthi and A.G. Ratnaparkhi for the Appellant. T.V.S.N. Chari Advocate for the Respondent The Judgment of the Court was delivered by DESAI	 J. Bonus has a tantalizing influence on industrial 756 workers. They look forward to it with a craving	 the degree of which is immeasurable. And for the employees and form of bonus has such a tremendous attraction that the time honoured concept of its being a profit sharing formula to fill in the gap between the fair wage and the living wage in the case of industrial workmen has been for all practical purposes displaced by the and bonus telescoping into Government service where there being no production and therefore it cannot be an incentive for higher production. And yet the management of The Model Mills	 Nagpur (Employer for short) has most successfully thwarted the meagre expectation of minimum bonus to its workmen for full two decades. Rashtriya Mill Mazdoor Sangh	 appellant herein	 ("Union ' for short) as an approved Union made four independent references under Sec. 73A of the Bombay Industrial Relations Act	 1946 ( 'Act ' for short) against Model Mills Nagpur for grant of bonus for the period 1964 65 to 1967 68. A separate reference was made in respect of each accounting year. The Union as representative Union of the employees served a notice of change making the demand for bonus. The matter was taken into conciliation. The Conciliation Officer recorded a failure on June 23	 1969 and issued a certificate under Sec. 73A of the Act certifying that the dispute was not capable of being settled by conciliation. Armed with the power of an approved Union the union made the aforementioned four references to the Industrial Court. The Union demanded bonus for each of the four accounting periods according to the provisions of the (Bonus Act ' for short). The Union could not make a specific demand for bonus calculated at a certain percentage of the salary alleging that as it has not got the requisite information about financial position and balance sheet of the Employer	 the Industrial Court should compute the bonus which becomes payable under the Bonus Act	 and award the same to the workmen of the Employer. The employer resisted the references on diverse grounds. It was contended that once a notified order is issued under Sec. 18A of the Industries (Development and Regulation) Act	 1951 (IDR Act short) appointing an authorised controller in respect of an industrial undertaking	 it is run by the authorised controller under the authority of a Department of the Central Government and therefore	 in view of the provision contained in Sec. 32(IV) of the Bonus Act its employees are excluded from the application of Bonus Act and the references must accordingly be rejected. 757 This contention found favour with the Industrial Court. The learned Member with the consent of the parties directed that the issue with regard to the application of the Bonus Act may be tried as a preliminary issue. The learned Member upheld the contention on behalf of the employer observing that having regard to the provision contained in Sec. 32(IV) of the Bonus Act read with Sec. 18A of the IDR Act	 the workmen employed by the employer are excluded from the operation of the Bonus Act as it is not applicable to the employer. The learned Member rejected the alternative contention that even if the workmen employed by the employer are not entitled to bonus under the Bonus Act	 they are yet entitled to claim bonus apart from the Bonus Act as a norm of industrial relation observing that as the demand was made for bonus under the Bonus Act and the alternative demand was not made before the Counciliator	 the scope of the references cannot be extended to cover the same. Accordingly	 all the four references were rejected. Hence these appeals by special leave. On the rival contentions following questions arise in these appeals: (1) On the appointment of an authorised controller under Sec. 18A of the IDR Act by the Central Government in respect of an industrial undertaking	 does it acquire the status of an establishment engaged in an industry carried on under the authority of the Department of Central Govt. (2) If the answer to the first question is in the affirmative	 whether the employees employed in such industrial undertaking are excluded from the operation of the Bonus Act. At the outset	 a few statutory provisions which will have a bearing and impact on the issues under examination may be noticed. The Industries (Development and Regulation) Act	 1951 was enacted to provide for development and regulation of scheduled industries. Chapter III confers power on the Central Government for regulation of scheduled industries. 'Scheduled industry ' is defined in Sec. 2(i) to mean any of the industries specified in the First Schedule. Textiles constitute a scheduled industry. Its entry is at plecitum 23 in First Schedule. 15 confers power on the Central 758 Government to cause investigation to be made into scheduled industries or industrial undertaking for the purposes therein set out. 15A confers similar power to direct investigation into the affairs of a company in liquidation owning an industrial undertaking. This specific power was conferred by introducing Sec. 15A in the Act by the Amending Act 72 of 1971 because a company which is being wound up under the orders of the court cannot be directly dealt with by the Central Government without the intervention of the court. 16 confers power on the Central Government to give directions on completion of an investigation under Sec. 15 to the industrial undertaking for the following purposes: "(a) regulating the production of any article or class of articles by the industrial undertaking or undertakings and fixing the standards of production; (b) requiring the industrial undertaking or undertakings to take such steps as the Central Government may consider necessary to stimulate the development of the industry to which the undertaking or undertakings relates or relate; (c) prohibiting the industrial undertaking or undertakings from resorting to any act or practice which might reduce its or their production	 capacity or economic value; (d) controlling the prices	 or regulating the distribution	 of any article or class of articles which have been the subject matter of investigation. " Chapter III A which was introduced by Amending Act 26 of 1954 conferred power on the Central Government to assume management or control of an industrial undertaking in certain cases. 18A(1) is relevant for the present purpose and it may be extracted: "18 A(1): If the Central Government is of opinion that: (a) an industrial undertaking to which directions have been issued in pursuance of Section 16 has failed to comply with such directions	 or (b) an industrial undertaking in respect of which an in 759 vestigation has been made under Section 15 (whether or not any directions have been issued to the undertaking in pursuance of Section 16)	 is being managed in a manner highly detrimental to the scheduled industry concerned or to public interest	 the Central Government may by notified order authorise any person or body of persons to take over the management of the whole or any part of the undertaking or to exercise in respect of the whole or any part of the undertaking such functions	 of control as may be specified in the order." Section 18A confers power on the Central Government either to assume management of an industrial undertaking or to control its management. The power to assume management of an industrial undertaking can be exercised by a notified order appointing an authorised controller to take over the management of the whole or any part of the undertaking. The Central Government may exercise in respect of the whole or any part of the undertaking such functions of control as may be specified in the order. 18B provides for the consequences that may ensure on the issue of a notified order under Sec. 18A authorising the taking over of the management of an industrial undertaking. Two consequences worth noticing are those set out in sub cl. (b) and (c) of Sec. 18B (1). They may be extracted: "(b) any contract of management between the industrial undertaking any managing agent or any director thereof holding office as such immediately before the issue of a notified order shall be deemed to have been terminated. (c) the persons	 if any	 authorised under Section 18 A to take over the management of an industrial undertaking which is a company shall be for all purposes the directors of industrial undertaking duly constituted under the Indian Companies Act	 1913 (7 of 1913)	 and shall alone be entitled to exercise all the powers of the directors of the industrial undertaking	 whether such powers are derived from the said Act or from the memorandum or articles of association of the industrial undertaking or from any other source. " 760 Section 18 E provides for continued application of the Companies Act then in force to the industrial undertaking in respect of which an authorised controller is appointed under Sec. 18 A subject to the limitations therein specified as it applied prior to the notified order. 18 F conferred power on the Central Government to cancel the notified order. Sec 32(iv) of the Bonus Act reads as under: "Nothing in this Act shall apply to . . . . . . . (iv) employees employed by an establishment engaged in any industry carried on by or under the authority of any department of the Central Government or a State Government or a local authority. " The question is: whether on the issue of a notified order under Sec. 18 A appointing an authorised controller in respect of an industrial undertaking governed by the IDR Act	 the employees of such undertaking are excluded from the application of the Bonus Act for the only reason that they are or have become the employees of an establishment in an industry carried on under the authority of the department of Central Government. The Bonus Act provides for payment of bonus to persons employed in certain establishments and for matters connected therewith. Sub Sec. (3) of Sec. 1 provides that save as otherwise provided in the Bonus Act	 it shall apply to (a) every factory; (b) every other establishment in which twenty or more persons are employed on any day during an accounting year. 32 excludes the application of the Bonus Act to the employees therein enumerated. Excluding Sec. 32 for the time being	 it cannot be disputed that the Bonus Act would apply to the industrial undertaking of the employer. Is the application of Bonus Act excluded on the ground that on the issuance of a notified order appointing an authorised controller under Sec. 18 A of the IDR Act	 because the employees of the respondents can be said to have been employed by an establishment engaged in any industry carried on or by or under the authority of any department of the Central Government. Can it be said that on the appointment of an authorised controller	 the industrial undertaking of the respondent acquired the status of an establishment engaged in textile industry carried on by or under the authority of a department of the Central Government ? In order to attract Sec. 32(iv) it must be shown that the employees sought to be ex 761 cluded from the operation of the Bonus Act have been employed by an establishment engaged in any industry carried on by or under the authority of the department of the Central Government. It was conceded that it cannot be said that on the appointment of an authorised controller	 the industrial undertaking acquired the status of an establishment engaged in textile industry carried on by the department of the Central Government It was	 however	 strenuously urged that it was an establishment engaged in the industry carried on under the authority of the department of the Central Government. Shorn of embellishment	 the question is: whether on the appointment of an authorised controller	 did the industrial undertaking acquire the status of an establishment engaged in the industry which is carried on under the authority of the department of the Central Government ? IDR Act was enacted as its long title shows to confer power on the Central Government to provide for development and regulation of scheduled industries. The Statement of objects and Reasons shows that the object behind the enactment was to provide the Central Government with the means of implementing their industrial policy and for that purpose to extend the control of the Central Government over the development and regulation of a number of important industries the activities of which affect the country as a whole and the development of which must be governed by economic factors of all India import. The Act amongst others confers power on the Central Government for regulating the production and development of the scheduled industries. Broad scheme of the Act shows that with a view to regulating the industrial expansion of this country on the threshold of development and to lay the infrastructure for the same	 the Central Government was armed with powers to order investigation into the affairs of the industrial undertaking as also. if necessary of a scheduled industry as a whole. The investigation may be caused to be made where there has been or likely to be a substantial fall in the volume of production or marked deterioration in the quality of article or an unwarranted rise in the price or for conserving any resources of national importance. On receipt of the report of investigation	 the Central Government could give necessary directions. These directions are statutory in character and they may be disobeyed on the pain of the management being divested from those incharge and vested in authorised controller	 who may be appointed by the Central Government. Therefore	 the Act provides not for taking over of the industrial undertakings. It provides for control of management by giving 762 directions or for change of management. Where the industrial undertaking is owned by a company governed by the Companies Act in force at the relevant time	 the management would generally vest in the Board of Directors	 and or the Managing Director	 as the case may be. Where it is a firm or a proprietary concern the partners or the proprietor	 as the case may be	 would be in the saddle of management. On the issue of a notified order appointing an authorised controller	 the person in charge of management including persons holding office as Managers or Directors of the industrial undertaking immediately before the issue of the notified order shall be deemed to have vacated their office as such. (Sec. 18 B(1). Further the contract of management between the industrial undertaking and any managing agent or any director thereof holding office as such immediately before the issue of the notified order shall be deemed to have been terminated. 18 B(1)(b). But the most important consequence that ensues on the issue of a notified order is to confer by a deeming fiction the position and powers of a director as duly constituted under the Companies Act on the authorised controller and he alone shall be entitled to exercise all the powers of the directors of the industrial undertaking	 whether such powers are derived from the Companies Act or from the memorandum or article of association of the industrial under taking or from any other source. (Sec. 18 B(1) (e). Further subject to the limitation specified in Sec. 18 E	 the Companies Act in force at the relevant time will continue to apply to such undertaking in the same manner as it applied thereto before the issue of the notified order under Sec. Thus the significant consequence that ensues on the issue of a notified order appointing authorised controller is to divert the management from the present managers and to vest it in the authorised controller. Undoubtedly	 the heading of Chapter III A appears to be slightly misleading when it says that the Central Government on the issue of a notified order assumes direct management of the industrial undertaking. In effect on the issuance of a notified order	 only the management of the industrial undertaking undergoes a change. This change of management does not tantamount to either acquisition of the industrial undertaking or a take over of its ownership because if that was to be the intended effect of change of management	 the Act would have been subjected to challenge of article 31 and 19(1)(f) of the Constitution. One can say confidently that was not intended to be the effect of appointment of an authorised controller. The industrial undertaking continues to be governed by the 763 Companies Act or the Partnership Act or the relevant provisions of law applicable to a proprietary concern. The only change is the removal of managers and appointment of another manager and to safeguard his position restriction on the rights of shareholders or partners or original proprietor. This is the net effect of the appointment of an authorised controller by a notified order. Can it then be said that on the issue of a notified order appointing an authorised controller	 the industrial undertaking is engaged in the industry carried on under the authority of the department af the Central Government. The expression `under the authority of any department of the Central Government ' would in ordinary parlance mean that the department is directly responsible for the management of the industrial undertaking. This responsibility may cover	 amongst others	 financial responsibility as well. Power to regulate management or control the management is entirely distinguishable from the power to run the industry under the authority of the department of the Central Government. The substitution of the management ordered under Sec. 18 A does not tantamount to the industrial undertaking being taken over by the department of the Central Government. Nor could it be said to be run under the authority of the department of the Central Government. In fact. as the authorised controller enjoys all the powers of directors conferred by the relevant provisions of the Companies Act	 he can exercise that power subject of course to any restriction or limitation on his power specified in the notified order or under the general supervision of the Central Government. But this power is subject to the in built limitation that it can be exercised for regulating the management of the industrial undertaking. Neither its identity nor its ownership is affected in any manner. This change in personal of management of the industrial undertaking for a specified period can never make the industrial undertaking one engaged in an industry carried on under the authority of the Central Government. On a pure grammatical construction	 of the expression 'establishment engaged in an industry carried on under the authority of the department of the Central Government ' cannot take in one in respect of which the Central Government in exercise of the power conferred by IDR Act directed a change of management. The conclusion in the preceding paragraph can be reached by a different route. Under Sec. 16 of the IDR Act	 the Central government enjoys wide powers to issue directions to the industrial undertaking as may 764 be appropriate in the circumstances for all or any of the purposes set out in various sub clauses of Sec. 16(1). The scheme of the Act shows that while retaining the original management	 the Central Government gives necessary directions for the aforementioned purposes to achieve a certain result. If the desired result is not achieved	 the Central Government enjoys a consequential power of changing the management by appointing an authorised controller so as to achieve the same result. This power to give directions without appointing an authorised controller or to appoint an authorised controller giving him specified directions is of a regulatory nature to be exercised with a view to regulating the managerial functions of the management of an industrial undertaking so as to achieve certain objects or to rectify the mismanagement in larger national interest without in any manner affecting the identity	 the status or the ownership of industrial undertaking. It could by no stretch of imagination be urged that on the exercise of the power to give directions under Sec. 16	 the industrial undertaking could be said to be engaged in any industry carried on under the authority of the department of the Central Government. Ipso facto the appointment of an authorised controller would not make the industrial undertaking one run under the authority of the department of the Central Government. While exercising power of giving directions under Sec. 16 the existing management is subjected to regulatory control	 failing which the management has to be replaced to carry out the directions. In either case the industrial undertaking retains its identity	 personality and status unchanged. On a pure grammatical construction of sub sec. (4) of Sec. 32	 it cannot be said that on the appointment of an authorised controller the industrial undertaking acquires the status of being engaged in any industry carried on under the authority of the department of the Central Government. Viewed from a slightly different angle	 it appears that the expression 'carried on by or under the authority of any department of the Central Government 'qualifies the expression 'industry ' and not the expression 'establishment ' as used in sub sec. (4) of Sec. 32 of the Bonus Act. Again on a pure grammatical construction it appears that where an industry is being carried on under the authority of any department of the Central Government	 the employed in an establishment in such an industry would be excluded from the operation of the Bonus Act. The underlying purpose of Sec. 32(iv) is not to exclude the employees of somestary establishment from the operation Act but to exclude all employees of all establishment in any industry which is carried on under the authority of the department of the 765 Central Government. If the expression `carried on by or under the authority of the department of the Central Government ' qualifies the expression `establishment ' it would lead to a startling result unintended by the framers of the Bonus Act. Let us illustrate it. There are two industrial undertakings engaged in the same industry situated side by side. In one case the management being incompetent or remiss	 an authorised Controller is appointed	 If the construction canvassed for on behalf of the respondent is accepted the employees of one would be excluded from the application of the Bonus Act and not the other though both are industrial undertaking engaged in the same industry. The framers of the Bonus Act which went to the length of making payment of bonus obligatory on industrial undertakings incurring losses could not have intended to treat the employees with such gross discrimination. On the contrary	 it appears that the intention was to exclude employees employed in an establishment engaged in any industry which is carried on by or under the authority of the department of the Central Government. It cannot be said that textile industry is being carried on under the authority of the department of the Central Government. There may be employees in an industrial undertaking engaged in textile industry which may have been established under the authority of the department of the Central Government. Ordinarily the Central Government would not like to treat an establishment set up by it in an industry in which there are other private sector establishments to differentiate and discriminate between employees of establishments engaged in the same industry. It	 therefore	 appears that the exception that is being carved out by Sec. 32(4) is in respect of employees of an industrial undertaking engaged in an industry carried on by or under the authority of any department of the Central Government as a whole and not individual establishments. All establishments in that industry which is carried on by or under the authority of the department of the Central Government would be excluded from the operation of the Bonus Act. Having examined the matter on principle	 let us turn to some precedents to which our attention was drawn. Sec. 2(a) of the defines `appropriate Government ' to mean (leaving aside the words which are not relevant for our purpose `in relation to any industrial dispute concerning any industry carried on by or under the authority of the Central Government	. .the Central Government. ' The expression used is any industry carried on by or under the authority of the 766 Central Government. This expression came up for consideration before this Court in the context of an industrial dispute between a Government Company as comprehended within the meaning of the expression in Sec. 617 of the Companies Act. Government Company is defined to mean `any company in which not less than fifty one per cent of the paid up share capital is held by the Central Government	 or by any State Government of Governments	 or partly by the Central Government and partly by one or more State Governments and includes a company which is a subsidiary of a Government Company as thus defined. ' An interesting question that came up for consideration before this Court was whether in respect of an industrial dispute between such Government Company and its workmen	 which is the appropriate Government which can make a reference of the industrial dispute for adjudication under Sec. 10 (1) of the . In respect of such Government Company this Court in Heavy Engineering Mazdoor Union vs The State of Bihar & Ors.(1) interpreting the expression `under the authority of ' held that the expression means `pursuant to the authority ' such as where an agent or a servant acts under or pursuant to the authority of his principal or master. The Court proceeded to examine the personality of an incorporated company which the law recognises as juristic person	 separate and distinct from its members. The Court concluded that `a commercial corporation acting on its behalf	 even though it is controlled wholly or partially by a Government department	 will be ordinarily presumed not to be a servant or agent of the State. In reaching this conclusion	 the Court approved the view of the Calcutta High Court in Carlsbad Mineral Water Mfg. Co. vs P. K. Sarkar wherein the Calcutta High Court had held that a business which is carried on by or under the authority of the Central Government must be a Government business. The High Court had further held that in an industry to be carried on under the authority of the Central Government	 it must be an industry belonging to the Central Government that is to say its own undertaking. Recalling here what is stated hereinbefore that on the change of management by appointment of an authorised controller	 the industrial undertaking retains its identity and continues to be governed by the Companies Act or the Partnership Act	 as the case may be	 and there merely take place only a change in the personnel of management but the substitute management	 say the authorised controller 767 appointed by the Central Government is to be presumed to be a Director for the purposes of the Bonus Act	 the conclusion is inescapable that the business remains that of the industrial undertaking and does not become one of the Central Government. The fact that the authorised controller is appointed by the Central Government and that he has to work subject to the directions of the Central Government does not render the industrial undertaking an agent of the Central Government and therefore	 could not be said to be an establishment engaged in an industry carried on by or under the authority of the Central Government. In fact	 this decision should conclude the point. However	 as our attention was drawn to some recent decisions wherein the same expression came up for consideration	 we may briefly refer to them. In Workmen	 Karnataka P.F. Employees Union vs Additional Industrial Tribunal & Anr.(1) the Karnataka High Court held that even if the Provident Fund organisation is an instrumentality of the State and therefore answers the definition of the expression `State ' in article 12 of the Constitution	 it cannot be said that it is an industry carried on by or under the authority of the Central Government	 for the purpose of determining which is the appropriate Government in respect of an industrial dispute between such instrumentality of the State and its workmen. In M/s Swadeshi Cotton Mills Thoznialar Shemalana Padukaypu Union vs M/s National Textile Corporation Ltd. & Ors.(2) the Union in its writ petition contended that as the National Textile Corporation a Government of India Undertaking was appointed as the authorised controller of the Swadeshi Cotton Mills under Sec. 18 A of the IDR Act on April 13	 1978 the appropriate Government in respect of such mill would be the Central Government and the State Government had no power to appoint the Conciliation Officer under the . Repelling this contention	 it was held that appointment of an authorised controller under Sec. 18 A by a notified order would not make the industrial undertaking an undertaking of the Central Government because by the appointment of the authorised controller	 the management of the industrial undertaking is changed to achieve a certain purpose and that too is a temporary phase. It was held that at any rate the appointment of an authorised controller does not vest the ownership of the industrial undertaking in the Central Government. Owner 768 ship is something more than management. Control of the whole or of a part of the industrial undertaking by the Central Government will not make the industrial undertaking an undertaking of the Central Government itself. In The Management of Bihar Khadi Gramodyog Sangh Mazaffarpur vs State of Bihar & Ors.(1) Patna High Court held that even though the Sangh was set up under the Khadi and Village Industries Commission	 yet it is not an industry carried on under the authority of the Central Government and the appropriate Government would be the State Government. Same view was also taken by the Bombay High Court in Abdul Rehman Abdul Gafur & Anr. vs Paul (Mrs. E.) & Ors.(2) In Bharat Glass Works (Pvt.) Ltd. vs State of West Bengal & Ors(3). the Calcutta High Court after following the earlier decision in Carlabad Mineral Water Manufacturing Co. repelled the contention that even though the appellant was a controlled undertaking in a scheduled industry under the IDR Act	 it was not an industry carried on under the authority of the Central Government and therefore	 the appropriate Government in respect of it would be the State Government. It is not necessary to multiply the decisions any more. But the same view appears to have been taken in the Indian Naval Canteen Central Board vs Industrial Tribunal	 Ernakulam & Anr.(4) A different note was sounded by the Bombay High Court in D.P. Kelkar	 Amalner vs Ambadas Keshav Bajaj & Ors.(5) In that case the employees of the India United Mills Ltd. approached the authority under the Payment of Wages Act for directing the employer to pay minimum bonus under the Bonus Act. It was contended on behalf of the employer that the employer mill was managed by an authorised controller appointed under Sec. 18 A of the IDR Act and therefore	 the workmen of the employer are employees employed by an establishment engaged in an industry carried on under the authority of the Central Government and consequently they were excluded from the operation of the Bonus Act in view of the provision contained in Sec. 32(iv). The authority under the payment of Wages Act negatived the contention. The matter came up before the High Court in two writ petitions under article 226 of the Constitution. The High Court rejected the construction canvassed before it that the 769 expression `carried on by or under the authority of any department of the Central Government qualified the expression `industry ' and not an `establishment ' engaged in an industry. After rejecting this plain grammatical construction for reasons which do not commend to us	 the High Court held that where the Central Government appointed an authorised controller under the IDR Act	 the industrial undertaking could be said to be engaged in an industry carried on under the authority of the Central Government. The High Court distinguished the decision of this Court in Heavy Engineering Mazdoor Union(1) observing that in the facts before the Supreme Court	 the company was one registered under the Companies Act and that it being an incorporated company	 it has an independent existence while where the authorised controller is appointed	 the management is taken over by the Central Government. We are unable to appreciate this view of the High Court for the reason that the High Court completely overlooked the purpose and intendment of appointing an authorised controller	 its effect on the continued existence of the industrial undertaking and the deeming fiction enacted in Sec. 18 B and the limitation on the powers of the shareholders placed by Sec. The High Court failed to notice the provision contained in sub section (2) of Sec. 18 E which clearly provides that subject to the provisions contained in sub section (1) and to the other provisions contained in the Act and subject so such other exceptions	 restrictions and limitations	 if any	 as the Central Government may	 by notification in the Official Gazette	 specify in this behalf	 the Indian Companies Act	 1913 shall continue to apply to such undertaking in the same manner as it applied thereto before the issue of the notified order under Sec. 18 A. ' This very important provisions which gives the clue to the expression `carried on under the authority of the Central Government ' was not taken note of by the High Court. Therefore	 the said view of the Bombay High Court does not commend to us and must be overruled. If on the issue of a notified order appointing an authorised controller under Sec. 18 A	 the management of the industrial undergoes a change	 yet it does not become an establishment engaged in an industry carried by the department of the Central Government	 its employees would not be excluded from the operation of the Bonus Act as provided in Sec. 32(4). The Tribunal therefore	 was clearly in error in rejecting the references holding that the workmen of the respondent were excluded from the operation of the Bonus Act. The Award of the Tribunal rejecting the references will have to be quashed and set aside 770 and the matter remitted to the Industrial Tribunal for disposing of the same on merits. An incidental argument was that the National Textile Corporation which has taken over the respondent Company would not be liable for the period when the authorised controller was incharge of the management of the respondent company. This contention has merely to be stated to be rejected. 5(1) of the Sick Textile Undertaking (Nationalisation) Act	 1974 provides that `every liability ' other than the liability specified in sub section (2) of the owner of a sick textile undertaking	 in respect of any period prior to the appointed day	 shall be the liability of such owner and shall be enforceable against him and not against the Central Government or the National Textile Corporation. `Sub cl. (c) of Sub sec. (2) of Sec. 5 provides that `wages ' salaries and other dues of employees of the sick textile undertaking	 in respect of any period after the management such undertaking had been taken over by the Central Government	 shall	 on and from the appointed day	 be the liability of the Central Government and shall be discharged	 for and on behalf of that Government	 by the National Textile Corporation as and when payment of such loans or amounts becomes due or as and when such wages	 salaries or other dues become due and payable. ' The appointed day has been specified as the 1st day of April	 1974. The expression `wages	 salaries and other dues of the employees ' would without a doubt include statutory bonus payable under the Bonus Act. This liability arose for the period after the management of the undertaking had been taken over by the Central Government by appointing an authorised controller under Sec. Therefore	 the liability to pay the bonus if awarded would be of the National Textile Corporation. The contention of the National Textile Corporation that it is not liable to pay bonus must be rejected. Accordingly	 these appeals succeed and are allowed and the four awards of the Industrial Court	 Maharashtra	 Nagpur Bench dated 27th November	 1970 in all the four references are quashed and set aside and all the four matters are remitted to the Industrial Court for disposal according to law on merits. As the cases are very old	 the Industrial Court is directed to dispose of the same within the period of four months from the receipt of this order. The respondent shall pay the costs of the appellant quantified at Rs. 2	000. N.V.K. Appeal allowed.

The appellant Union served a notice of demand for the grant of bonus for the period 1964 65 to 1967 68. The matter was taken into conciliation. The Conciliation Officer recorded a failure	 issued a certificate under Section 73A of the Bombay Industrial Relations Act	 1946 certifying that the dispute was not capable of being settled by conciliation. The Union thereupon made four independent references to the Industrial Court	 for the grant of bonus for each of the four accounting years 1964 65 to 1967 68. The Union further alleged that it could not make a specific demand for bonus calculated at a certain percentage of the salary as it had not got the requisite information about the financial position and the balance sheet of the Employer	 and that the Industrial Court should compute the bonus which becomes payable under the Bonus Act	 and award the same to the workmen. The employer resisted the references contending that once a notified order was issued under Section 18A of the Industries (Development and Regulation) Act	 1951 appointing an authorised controller in respect of an industrial undertaking	 it was run by the authorised controller under the authority of a Department of the Central Government and therefore	 in view 752 of the provisions contained in Section 32(IV) of the Bonus Act its employees were excluded from the application of the Bonus Act and the references must consequently be rejected. The Industrial Court upheld the aforesaid contention on behalf of the employer that having regard to the provisions contained in Section 32(IV) of the Bonus Act read with Section 18A of the IDR Act	 the workmen employed by the employer were excluded from the operation of the Bonus Act as it was not applicable to the employer. The Industrial Court however rejected the alternative contention that even if the workmen employed by the employer were not entitled to bonus under the Bonus Act	 they were yet entitled to claim bonus apart from the Bonus Act as a norm of industrial relations by observing that as the demand was made for bonus under the Bonus Act	 and the alternative demand was not made before the Conciliation Officer	 the scope of the references could not be enlarged to cover the same. In the appeals to this Court on the questions: (1) On the appointment of the authorised controller under Section 18A of the IDR Act by the Central Government in respect of an industrial undertaking whether the undertaking acquires the status of an establishment engaged in an industry carried on under the authority of the Department of the Central Government	 and (2) Whether the employees employed in such an industrial undertaking were excluded from the operation of the Bonus Act. Allowing the Appeals	 ^ HELD: 1(a) If on the issue of a notified order appointing an authorised controller under Sec. 18A Industries (Development and Regulation) Act 1951	 the management of the industrial undertaking undergoes a change	 yet it does not become an establishment engaged in an industry carried on by the department of the Central Government	 and therefore its employees would not be excluded from the operation of the as provided in Sec. 32(IV).

(b) The Industrial Tribunal was clearly in error in rejecting the references holding that the workmen of the respondent were excluded from the operation of the Bonus Act. [769 H] 1.(c) The Award of the Industrial Tribunal rejecting the references is quashed and set aside and the matter remitted to the Industrial Tribunal for disposal on merits. [769 H] 2.(a) The Industries (Development and Regulation) Act	 1951 was enacted to confer power on the Central Government to provide for development and regulations of scheduled industries. With a view to regulating the industrial expansion of the country and to lay the infrastructure for the same	 the Central Government armed itself with the powers to order investigation into the affairs of an industrial undertaking as also	 if necessary of a scheduled industry as a whole. The investigation may be caused to be made where there has been or likely to be a substantial fall in the volume of production or marked deterioration in the quality of an article or an unwarranted rise in the price or for conserving any resources of national importance. On receipt of the report of investigation	 the Central Government could give necessary directions. These directions are statutory in character. [761 E G] 2. (b) The Act provides not for taking over of the industrial undertaking. It provides for control of management by giving directions or for change of management. Where the industrial undertaking is owned by a company governed by the Companies Act in force at the relevant time	 the management would generally vest in the Board of Directors	 and/or the Managing Director	 as the case may be. Where it is a firm or a proprietary concern the partners or proprietors as the case may be	 would be in the saddle of management. [761 H; 762 A B] 2.(c) On the issue of a notified order appointing an authorised controller	 the person in charge of management including persons holding office as Managers or Directors of the industrial undertaking immediately before the issue of the notified order shall be deemed to have vacated their office as such. The contract of management between the industrial undertaking and any managing agent or any director thereof holding office immediately before the issue of the notified order shall be deemed to have been terminated. Subject to the limitation specified in Sec. 18E	 the Companies Act in force at the relevant time will continue to apply to such undertaking in the same manner as it applied thereto before the issuance of the notified order under Sec. 18A. [762 B E] 2. (d) The significant consequence that ensues on the issue of a notified order appointing an authorised controller is to divert the management from the present managers and to vest it in the authorised controller. This change of management does not tantamount to either acquisition of the industrial undertaking or a take over of its ownership. The industrial undertaking continues to be governed by the Companies Act or the Partnership Act or the relevant provisions of law applicable to a proprietary concern. The only change is the removal of managers and appointment of another manager and 754 to safeguard his position restriction on the rights of shareholders or partners or original proprietor. This is the net effect of the appointment of an authorised controller by a notified order. [762 F H; 763 A B] 3. The expression 'under the authority of and department of the Central Government ' would in ordinary parlance mean that the department is directly responsible for the management of the industrial undertaking. This responsibility may cover amongst others	 financial responsibility as well. Power to regulate management or control the management is entirely distinguishable from the power to run the industry under the authority of the Central Government. [763 C D] 4. The substitution of the management ordered under Sec. 18 A does not tantamount to the industrial undertaking being taken over by the department of the Central Government. Nor could it be said to be run under the authority of the department of the Central Government. As the authorised controller enjoys all the powers of directors conferred by the relevant provisions of the Companies Act	 be can exercise that power subject of course to any restriction or limitation on his power specified in the notified order or under the general supervision of the Central Government. But this power is subject to the in built limitation that it can be exercised for regulating the management of the industrial undertaking. Neither its identity nor its ownership is affected in any manner. The change in personnel of management of the industrial undertaking for a specified period can never make the industrial undertaking one engaged in an industry carried on under the authority of the Central Government. [763 E G] 5. Under Sec. 16 of the IDR Act	 the Central Government enjoys wide powers to issue directions to the industrial undertaking as may be appropriate in the circumstances for all or any of the purposes set out in the various sub clauses of Sec. 16(1). This power to give directions without appointing an authorised controller or to appoint an authorised controller giving him specified directions is of a regulatory nature to be exercised with a view to regulating the managerial functions of an industrial undertaking so as to achieve certain objects or to rectify the mis management in larger national interest without in any manner affecting the identity	 the status or the ownership of the industrial undertaking. The appointment of the authorised controller would not make the industrial undertaking one run under the authority of the department of the Central Government. While exercising power of giving directions under Sec. 16 the existing management is subjected to regulatory control	 failing which the management has to be replaced to carry out the directions. In either case the industrial undertaking retains its identity	 personality and status unchanged. [763 H; 764 B E] 6. The underlying purpose of Sec. 32(IV) of the Bonus Act is not to exclude the employees of some stray establishment from the operation of the Act but to exclude all employees of all establishments in any industry which is carried on under the authority of the department of the Central Government. [764 H] 7. The expression 'carried on by or under the authority of any department of the Central Government ' qualifies the expression industry and not 755 the expression 'establishment ' as used in sub sec. (iv) of Sec. 32 of the Bonus Act. [765 A] 8. The intention of the framers of the Bonus Act was to exclude employees employed in an establishment engaged in any industry which is carried on by or under the authority of the department of the Central Government. It cannot be said that textile industry is being carried on under the authority of the department of the Central Government. There may be employees in an industrial undertaking engaged in textile industry which may have been established under the authority of the department of the Central Government. Ordinarily the Central Government would not like to treat an industrial establishment set up by it in an industry in which there are other private sector establishments to differentiate and discriminate between employees of establishments engaged in the same industry.[765 C E] 9. The exception that is being carved out by Sec. 32(IV) is in respect of employees of an industrial undertaking engaged in an industry carried on by or under the authority of any department of the Central Government as a whole and not individual establishments. [765 E] 10. The expression 'wages '	 salaries and other dues of the employees ' occurring in sub cl. (c) of sub sec. (2) of Sec. 5 of the Sick Textile Undertaking (Nationalisation) Act	 1974 would without doubts include statutory bonus payable under the Bonus Act. [770 E] In the instant case	 the liability arose for the period after the management of the undertaking had been taken over by the Central Government by appointing an authorised controller under Sec. 18A of the IDR Act. Therefore	 the liability to pay the bonus if awarded would be of the National Textile Corporation. [770 E]
