Summarize the following court judgment. Appeal No. 20 of 62. Appeal by special leave from the award dated September 29	 1960	 of the Industrial Tribunal Punjab	 Patiala in reference No. 13 of 1960. C.K. Daphtary	 Solicitor General of India	 Bhagirath Das and B. P. Maheshewari	 for the appellants. M. K. Ramamurthi	 B. K. Gary	 D. P. Singh and section C. Aggarwal	 for the respondent No. 2(i). September 7. The Judgment of Gajendragadkar and Das Gupta	 JJ.	 was delivered by Gajendragadkar	 J. Mudholkar J. delivered a dissenting judgment. GAJENDRAGADKAR	 J. This appeal by special leave arises out of an industrial dispute in relation to a comparatively minor demand made against the appellants by the respondents their employees but in challenging the validity of the award passed by the Industrial Tribunal in favour of the 933 respondents on that demand the learned Solicitor General has raised a general question before us. He contends that in granting the demand made by the respondents	 the award has illegitimately and unjustifiably trespassed on the appellants ' freedom of contract. The appellants as employers	 are entitled tofix the terms of employment on which they would be willing to employ workmen and it is open to the workmen either to accept those terms or not; industrial adjudication should not interfere in such a matter. That is the nature of the general contention which has been raised before us in the present appeal. The facts leading to the dispute are few and they lie within a very narrow compass. The appellants are the Trustees of the Tribune Press and paper and the Trust is being worked in accordance with the terms of the will executed by Dyal Singh Majithia on June 15	 1895. In carrying out the policy of the Trust	 the five appellants have executed a power of Attorney in favour of Mr. R. R. Sharma and the Press is managed and the paper is conducted to carry out the policy laid down by the will. It appears that before July 1	 1956	 for the purposes of leave	 the appellants had divided their employees into two categories (1) the Linooperators and (2) the rest of the workmen in the Press Section; and Rule 57 made provision for leave on the basis of the said classification. The effect of the said rule was that no Press worker other than the lino operator was entitled to any kind of paid leave although he was given the right to claim 30 days ' wages plus dearness allowance payable in January every year if he had worked for 11 Months. In addition	 the said press worker was entitled to Quarantine leave on the terms mentioned in Rule 53. 934 This position was substantially altered on the July 12 1956	 when the appellants framed a new Rule in respect of earned leave. This rule abolished the two categories of workers on which the earlier rule 57 was based and divided the workers into two categories (i) workers who were employed on or before 1.7.1956 and (ii) those who were employed after 1.7. 1956. In respect of the former category of workmen	 the new Rule made the following provision: "Subject to the provisions of the Indian 	 every workman in the service of the Tribune on the 1st July	 1956	 will be entitled to 30 days ' leave with wages after having worked for a period of 11 months. This leave shall cease to be earned	 when it amounts to 60 days" In regard to the workmen falling under the latter category	 earned leave was to be governed by the provisions of section 79 of the Indian . It is common ground that the provision for earned leave made by the said section is a provision for minimum earned leave which the employer is bound to give: whether or not additional leave should be granted by way of earned leave is a matter within the discretion of the employer. As a result of the new rule	 the position was that the employees who had joined the service of the appellants on or before July 1	 1956	 were entitled to 30 days ' earned leave with wages	 whereas those who joined after the said date became entitled to the statutory minimum of 21 days of earned leave. At the time when this rule came into force there were 94 old employees to whom the rule applied and 27 new employees to them by virtue of the new Rule	 section 79 of the was made 935 applicable. Gradually	 new hands have also been employed and to all such new employees section 79 is applicable. It appears that by its resolution passed on January 8	 1960	 the Tribune employees union sent to the Management a charter embodying about 20 demands. Attempts at conciliation were made but they failed and so	 on April 4	 1960	 eight of the said demands were referred by the Punjab Government to the Industrial Tribunal for its adjudication under section 10 of the Industrial Disputes Act. One of these demands was in rela tion to earned leave. The demand was that the employees in the Press Section should be allowed 30 days ' earned leave with full wages for every months ' service without any discrimination. The Tribunal has allowed this demand and it bad held that all workmen of the Press are entitled to 30 days ' earned leave without making any distinction a between workmen who joined before July 1	 1956	 and those who joined subsequently. It is the validity of this award which is questioned before us by the appellants. The broad and general question raised by the learned Solicitor General on the basis of the employer 's freedom of contract has been frequently raised in industrial adjudication	 and it has consistently been held that the said right is now subject to certain principles which have been evolved by industrial adjudication in advancing the cause of social justice. It will be recalled that as early as 1949	 it was urged before the Federal Court in Western India Automobile Association vs The Industrial Tribunal Bombay(1) that the industrial Tribunal had no jurisdiction to direct an employer to reinstate his dismissed employees and the plea made was that such a direction was contrary to the known principles which govern the relationship between master and servant. This contention was negatived by the Federal Court. (1) 	120. 936 Speaking for the Court	 Mahajan J. as he then was	 observed that the award of the Tribunal may contain provisions for the settlement of a dispute which no Court could order if it was bound by ordinary law	 but the Tribunal is not fettered in any way by these limitations. The same plea was again raised before this Court in The Bharat Bank Ltd.	 Delhi. vs The. Employees of The Bharat Bank Ltd.	 Delhi (1) and Mukherjea J. as he then was	 emphatically rejected it. "Insettling the disputes between the employers and the workmen"	 observed the learned Judge	 "the function of the Tribunal is not confined to administration of justice in accordance with law. It can confer rights and privileges on either party which it considers reasonable and proper	 though they may not be within the terms of any	 existing agreement. It has not merely to interpret or to give effect to the contractual rights and obligations of the parties. It can create new rights and obligations between them which it considers essential for keeping industrial peace. " This view has been consistently accepted by industrial adjudication since 1949. The doctrine of the absolute freedom of contract has thus to yield to the higher claims for social justice. Take	 for instance	 the case where an employer wants to exercise his right to employ industrial labour on any wages he likes. It is not unlikely that in an economically under developed country where unemployment looms very large. for Industrial work	 employees may be found willing to take employment on terms which do not amount to a minimum basic wage. Industrial adjudication does not recognise the employer 's right to employ labour on terms below the terms of minimum basic wage. This	 no doubt	 is an interference with the employer 's (1) ; 	 513. 937 right to hire labour	 but social justice requires that the right should be controlled. Similarly the right to dismiss an employee is also controlled subject to well reorganised limits in order to guarantee security of tenure to industrial employees. In the matter of earned leave	 s.79 of the prescribes a minimum in regard to establishments to which the Act applies. In the matter of bonus which is not regarded as an item of deferred wages	 industrial adjudication has evolved a formula by the working of which employees are entitled to claim bonus	 We have referred to these illustration to show bow under the impact of the demand of social justice	 the doctrine of absolute freedom of contract has been regulated. It is	 however	 necessary to add that the general question about the employer 's right to manage his own affairs in the best way he chooses cannot be answered in the abstract without reference to the facts and circumstances in regard to which the question is raised. If a general question is posed and an answer must be given to it	 the answer would be both yes and No. The right would be recognised and industrial adjudication would not be permitted or would be reluctant to trespass on that right or on the field of management functions unless compelled by over riding consi derations of social justice. The right would not be recognised and would be controlled if social justice and industrial peace require such regulation. That is why we think industrial adjudication always attempts not to answer questions in the abstract in order to evolve any general or inflexible principles. The eat course to adopt in dealing with industrial disputes is to consider the facts of the case	 the nature of the demand made by employees	 the nature of the defence raised by 938 the employer and decide the dispute without unduly enlarging the scope of the enquiry. If in the decision of the dispute	 some principles have to be followed or evolved	 that must be done: but care must be taken not to evolve larger principles which would tend to prejudge issues not directly raised in the case before the Industrial Tribunal. That is why we think we would not be justified in giving any general answer to the broad contention raised by the learned Solicitor General before us in the present appeal. The development and growth of industrial law during the last decade presents a close analogy to the development and growth of constitutional law during the same period. In some respects	 itis well know that article 19 of the Constitutionhag guaranteed fundamental rights to individualcitizens and at the same time	 has provided forthe regulation of the said fundamental rights subject to the provisions of cls. (2) to (6) of the said Article. Where a conflict arises between the citizen 's fundamental right to hold property and a restriction sought to be imposed upon that right in the interest of the general public	 courts take the precaution of confining their decision to the points raised before them and not to lay down unduly broad and generaI propositions. As in the decision of constitutional questions of this kind	 so in industrial adjudication it is always a matter of making a reasonable adjustment between two competing claims. The fundamental right of the individual citizen is guaranteed and its reasonable restriction is permissible in the interest of the general public	 so	 the claims of the interest of the general public have to be weighed and balanced against the claims of the individual citizen in regard to his fundamental right. So too	 in the case of industrial adjudication 939 the claims of the employer based on the freedom of contract have to be adjusted with the claims of industrial employees for social justice. The process of making a reasonable adjustment is not always easy	 and so	 in reaching conclusions in such a matter	 it is essential not to decide more than ' is necessary. If industrial adjudication pur ports to lay down broad general principles	 it is likely ;to make its approach in future case#; inflexible and that must always be avoided. In order that industrial adjudication should be completely free from the tyranny of dogmas or the sub conscious pressure of pro conceived notion	 it is of utmost 'importance that the temptation to lay down broad principles should be avoided. In these matters	 there are no absolutes and no formula can be evolved which would invariably give an answer to different problems which may be posed in different cases on different facts. Let us	 therefore	 revert to the facts of this case and decide whether the appellant 's attack against the validity of the propriety of the award can be sustained. In dealing with the narrow dispute presented by this appeal	 it is necessary to remember that all the employees of the appellants are governed by the same terms and conditions of 	service	 except in regard to earned leave. It is only in respect of this term and condition of service that a distinction is made between workmen employed on or before 1.7. 56 and those employed after that date. Generally	 in the matter of providing leave rules	 industrial adjudication prefers to have similar conditions of service in the same industry situated in the same region. There is no evidence adduced in this case in regard to the condition of earned leave prevailing in the comparable industry in this region. But we cannot ignore the fact that this 940 very concern provides for better facilities of earned leave to a section of its employees when other terms and conditions of service are the same in respect of both the categories of employees. It is not difficult to imagine that the continuance of these two different provisions in the same concern is likely to lead to dissatisfaction and frustration amongst the new employees. It cannot be denied that the existence of industrial peace and harmony and the continuance of the said peace and harmony are relevant factors	 but their importance should not be unduly exaggerated. If a frivolous demand is made by the employees and it is accompanied by a threat that non compliance with the demand would lead to industrial disharmony or absence of peace	 it would be unreasonable to treat the thrust as relevant in deciding the merits of the demand. In this connection	 it is necessary to remember that the continuance of harmonious relations between the employer and his employees is treated as relevant by industrial adjudication	 because it leads to more production and thereby has a healthy impact on national economy	 and so it is necessary that in dealing with several industrial disputes	 industrial adjudication has to bear in mind the effect of its decisions on national economy. In their zest to fight for their respective claims	 the parties may choose to ignore the demand of national economy	 but industrial adjudication cannot. If the demand is plainly frivolous	 it has to be rejected whatever the consequences may be. In the present case	 the argument that the continuance of two different provisions would lead to disharmony cannot	 however	 be treated as frivolous. It is difficult to understand on what principle the discrimination is based. The only argument urged in support of the discrimination is the employer 's right to provide for new terms of service to the new entrants in service. In our 941 opinion	 the validity of this argument cannot be accepted in the circumstances of this case. Take the case of the wages or dearness allowance which the Appellants paid to their employees. Would the appellants be justified in assertion of their right of freedom of contract to offer less favourable terms of wages or dearness allowance to employees who would be employed after a certain date ? If the general point raised by the learned Solicitor General is upheld without any qualifications	 then it would be open to the employer to fix different wages for different sets of workmen who are doing the same kind of work in his concern. We have rarely come across A case where such a claim has either been made or has been upheld. It is well known that both industrial legislation and industrial adjudication seek to attain similarity or uniformity of terms of service in the same industry existing in the same region	 as far as it may be practicable or possible	 without doing injustice or farm to any particular employer or a group of employers That being so	 we do not think the Tribunal was in error in holding that in the matter of earned leave	 there should be uniformity of conditions of service governing all the employees in the service of the appellants. There is another aspect of this question to which reference must be made. This is not a case in which the financial liability imposed on the employer by the award when it directed the employer to grant the earned leave of 30 days to all the employees	 is very heavy; and so	 having regard to the fact that the appellants have been conducting their business in a profitable way and their financial position is distinctly good	 no attempt has been made before us and rightly	 to suggest that the burden imposed by the award is beyond their means. it is not disputed that the total annual liability which 942 may accrue as a result of the award may not exceed Rs. 1	000/ 	 and it is also common ground that the appellants are a flourishing concern and their not profits which were in the neighbourhood of a lac of rupees in 1949	 have shown an upward tendency and have reached almost rupees eight lacs in 1959. That is another factor which has to be borne in mind in dealing with the present dispute. It is not suggested by the appellants that the provision made by them for earned leave in respect of old employees is unduly generous of extravagant and so	 it has become necessary to invoke the provisions of section 79 of the in respect of new employees. On the other hand	 earned leave provided by section 79 is the minimum statutory leave to which employees are entitled and if the appellants thought it necessary to provide for additional earned leave to their old employees	 there is no reason why they should not make a similar provision in respect of the new employeesas well. We ought to add to that on the record	 it does appear that the appellants are good employees and they are treating their employees in a liberal manner. It	 however	 appears that they have brought the present dispute to this Court more for asserting the general principle of the employer 's right to fix conditions of service with his new employees than for vindicating any real or substantial grievance against the award which would prejudicially affect their interest. In our opinion	 having regard to the nature of the dispute raised in the present appeal and the other relevant facts and circumstances	 it cannot be said that the Industrial Tribunal erred in law in directing the appellants to provide for the same uniform rule as to earned leave for all their employees. We are satisfied that the award under appeal cannot be set aside only on the academic or abstract point of law raised by the appellants. 943 The result is	 the appeal fails and is dismissed with costs. MUDHOLKAR	 J. This is an appeal by special leave from the award of the Industrial Tribunal	 Punjab. The appellants before us are the trustees of 'The Tribune ' Ambala Cantt. and the opposite party to the appeal consists of the workmen of the Tribune through their two unions	 one the Tribune Employees ' Union and the other the Tribune Workers ' Union. The Trust was founded in Lahore by the late Sardar Dayal Singh Majithia on February 1	 1881. It publishes the newspaper "Tribune". By the will of the founder dated June 15	 1895 the Management of the Tribune was vested in a public trust in September	 1898. After the partition of India the offices of the newspaper had to be shifted from Lahore and they are now located at Ambala. The Trust naturally had to leave the entire machinery and other equipment of the Tribune Trust along with its immovable property in Lahore. The value of that property is stated by the appellants to be Rs. 25 lakhs or so. The Trust was however	 able to transfer its bank accounts and Government securities to India a few days before the partition. With the help of these assets it reestablished the Tribune Press and office at Ambala and established new machinery at a cost of Rs. 15 lakhs or so. Gradually the Trust has been able to rehabilitate its fortunes. It is not disputed before us that despite the heavy loss entailed by the Trust by reason of being uprooted from Pakistan	 the employees quite a number of whom are old employees who were able to migrate to India	 have been treated with a great deal of consideration. After the Tribune started making profits the employees are being given bonus every year. Moreover even before the Employees Provident Fund scheme applicable to newspaper 944 industry and even before the scheme of gratuity for all categories of employees were enforced by statute be Tribune had provided for both provident fund and gratuity to its employees. In addition to this it has provided free housing accommodation to its workmen in two colonies	 one built in 1955 with the help of subsidy from the Government of India and the other in the year 1958 at a cost of Rs. 6 lakhs. The quarters in the two colonies are provided with modern sanitation Besides that	 there are extensive recreation grounds	 lawns etc.	 in these colonies. Even electricity is supplied free to the employees. Several other amenities are also provided by the Trust. It would thus appear that the welfare of the employees has been kept prominently in mind by the trustees. Even so	 some disputes arose between the management and the employees. Ultimately eight demands made by the employees were referred by the Government of Punjab for adjudication under section 10(1) of the industrial Disputes Act	 1947 (14 of 1947) to the Industrial Tribunal	 Punjab	 Patiala constituted under s.7A of the Act. Four demands were rejected by the Tribunal as having been withdrawn	 one was settled amicably and on the remaining three the Tribunal has made its award. One of those three demands is : "Whether the employees in the Press Section should be allowed 30 days ' earned leave with full wages for every 11 months ' service without discrimination ?" The Tribunal hold in favour of the workmen and it is only against this part of the award of the Tribunal that the trustees have come up in appeal before us. Certain facts have to be stated in connection with this demand. The Trust had framed certain rules governing the conditions of service of 945 its employees. Rule 57 of those rules deals with leave and reads thus : "The Lino Operators shall be entitled to 30 days ' leave of all description (luring the course of a calendar year	 which will be with pay plus all allowances. Press employees	 other than the Lino operators may be granted leave by the competent authority from time to time as the authority may determine. Such leave shall be without pay or allowance. They shall	 however	 be entitled to in the month of January every year to receive a sum amounting to the leave pay plus ordinary dearness allowance for the preceding month of December for the period of II months ' service or to a proportionate amount for a lesser period. In addition	 Press workers will be entitled to quarantine leave on the terms mentioned in Rule 53". On July 1	 1956 a new rule was framed which reads as follows : "(1) Subject to the provisions of the Indian 	 every workman in the service of the Tribune on the 1st July	 1956	 will be entitled to 31 days ' leave with wages		 after having worked for a period of II months. This leave shall cease to be earned	 when it amounts to 60 days. (2) A workman joining the service of the Tribune after the 1st July	 1956 will be entitled to leave	 in accordance with the provisions of section 79 of the Indian . " Under the old rule the Lino Operators in the press section were allowed 30 days ' leave on full wages 946 including dearness allowance. The other workers in the press section were	 however	 allowed not leave with pay	 but 30 days ' wages in the month of January calculated on the basis of the full wages drawn in the preceding month provided that an employee had served for a period of II months till the beginning of the month of January. If he had served for a lesser period he was to be paid propor tionately less amount. Bearing in mind the fact that in industries leave	 vacation and holidays with pay are regarded as supplemental pay practices (see Collective Bargaining principles and Cases by John T. Dunlop and James J. Healy	 revised edn.	 p. 433)	 in substance even the employees in the press section other than lino operators got the same money equivalent of the leave allowed to lino operators. It may be mentioned that these other press section employees were also entitled to take leave but the rule provided that they will Dot be paid any pay and allowances for such leave. That was perfectly reasonable because they got pay in lieu of paid leave for an additional period in the month of January. However	 even this slight distinction in the mode of conferring benefits on the two categories of employees was abolished by the new rule which came into force on July 1	 1956	 and all employees in the press section upto that date were made eligible for the grant of 30 days ' leave with wages after having worked for a period of 11 months. It 'May be mentioned here that the of 1948 provided in a. 79 that every worker who has worked for a period of 240 days or more in a calendar year shall be given at least one days ' leave for every 20 days of service. No doubt this was the minimum provided by the Act but since the press section is governed by the it was open to the Trust to modify its rules with regard to all employees of this section and grant leave according to the provisions of this 947 section. There is no prohibition in law against doing so but still it did not wish to revise unfavourably its rules regarding the quantum of leave to its existing employees. It	 however	 felt that in view of the statutory provision there was no obligation upon it to provide for a longer leave than that laid down in section 79 of the . It was for this reason that it provided that all employees engaged on or after July 1	 1956	 will be granted leave according to the provisions of section 79 of the 	 the idea being that eventually all employees should be governed by the rules. Apparantly	 to forestall this consequence the employees contend that the new rule has introduced discrimination. That is why they raised a dispute relating to this matter and it was referred to the Tribunal along with the other disputes they had raised. The Tribunal	 dealing with this matter	 has observed as follows : "It may be of some importance to note that till 1st July	 1956 the workmen who had entered service before that date and those who had been employed thereafter were in the matter of leave compensation	 treated alike. It was on 1st July	 1956 for the first time that the workmen who had been in service before that date were given 30 days ' paid leave but for now entrants the number of days of that leave was reduced to that permitted by section 79 of the . The Union 's contention is that to allow 3 days ' earned leave with full wages in an year to a certain group of workmen in Press Section and to deny that benefit to the rest of the workmen of that section simply on the score of their having entered service after 1st July	 1956	 is to acknowledge the prominent element of discrimination which has been res 948 ponsible for the heart burning	 resentment and dissatisfaction of the workmen. It is further urged with emphasis that all workers for the Press Section should in the matter of earned leave be treated equally. For the long space of seven years even after the had come into force the management had continued to treat all workmen of the Press Section alike irrespective of the date of their employment. There is no reason why a distinction of a discriminatory nature and effect be made between the two artificially created sets of workmen belonging to the same section. " It seems to me that the Tribunal 's ultimate finding is vitiated by a misconception entertained by it. The first sentence in the above quotation would show that the Tribunal thought that those persons who were employed after July 1	 1956 were treated in the matter of leave on par with those employed before July 1	 1956	 	till July 1	 1956" but were sought to be discriminated against only thereafter. It is difficult to understand how persons who were employed after July 1	 1956	 could possibly be treated before July 1	 1956	 equally with employees who were in service on that day. Apparently it is this confusion in the mind of the Tribunal which has influenced its ultimate conclusion. That apart	 it is quite clear that what the Trust has done is to put in one category persons who enjoyed in substance the same kind of benefit uptil July 1	 1956 and permit them to enjoy the benefit they bad hitherto enjoyed. Then it put in a separate category those persons who could never possibly lay any claim to have enjoyed a similar benefit because they were not its employees till July 1	 1956	 and decided that they will get leave only as provided in section 79 of the . All persons in each category are intended to be alike and	 therefore the 949 question of discrimination does not in fact arise. It was	 in my opinion	 open to the management to offer to the new entrants now terms. When the new entrants entered service accepting the new terms and knowing fully well that one of those terms i. e.	 the one relating to annual leave was different and less beneficial from the one which obtained in the case of the old employees	 it is not reasonable for them now to say that they are being discriminated against. The Tribunal	 however	 thinks otherwise. It has held that the Trust	 by treating the now entrants less favourably in the matter of leave than its old employees has practiced discrimination and that this discrimination has caused heart burning. Presumably	 therefore	 the Tribunal felt impelled to interfere and direct that the new entrants should be treated ' in the matter of leave on par with the old employees in ' order to avoid industrial unrest which may result 'from ' heart burning amongst the new entrants. What we must first consider is whether the existing of heart burning has at all been established in this case. It is said that the continuance of different provisions in the same concern has caused heart burning	 dissatisfaction and frustration among the new employees and this would lead to unrest in the industry. For one thing	 there is no evidence before us to show that the new employees are making a very serious grievance of the fact that they would get a few days less of leave than the old employees. All that Mr. Ramamurti could point out to us was the statement in the evidence of Som Nath	 A. W. 7. that he should also be given 30 days	 privilege leave in a year. Merely saying that he should be given privilege leave does not mean that he is harbouring bitterness in his mind. Apart from that it would be extremely unreasonable to take notice of bitterness	 if any	 in the minds of 950 these new employees in regard to this matter because. as already stated	 they voluntarily took up employment knowing that they would got less leave than the old employees. Som Nath 's statement is no evidence of the fact that there is any heart burning. To say that the very fact that two sets of people are governed by different rules will necessarily lead to heartburning	 without establishing anything more	 such as inadequacy of the benefit enjoyed by one set will be to ignore that such differences are a matter of common occurrence and no reasonable person is expected to magnify their consequences. It seems to me	 further	 that the workers as a body did not think much of the distinction between the extent of leave enjoyed by old and new employees because during all the four years while the rule has been in force they raised no protests. No doubt they did ultimately make a protest in the year 1960 when the dispute was referred to the Tribunal. But then	 this was not the sole dispute but was one of eight disputes	 at least four of which were withdrawn by the Unions	 apparently after realising that there was no substance in them. The mere fact that they did not withdraw this dispute would not of itself indicate that they regarded it as of great importance. It may well be that they did not withdraw it in an erroneous belief that anything which is characterised as discrimination will at once earn the sympathy of Industrial Tribunals and the Courts. Even assuming that is creating heartburning amongst the employees the question arises whether they have a real grievance. They say that the Trust has discriminated against the new entrants and this is their grievance. In this connection it may be observed that the more refusal or failure of an employer to treat equally all its employees doing a particular kind of work would not necessarily amount to discrimination. The subject of is d 951 crimination has come up for consideration before this Court in a largo number of cases in which a complaint has been made that the equality clause of the Constitution	 article 14	 has been violated. This Court has held that It is open to the State to make reasonable classification both as regards persons and as regards things (see in particular Budhan vs State of Bihar(1) ; Khandige Sham Bhatt vs Agricultural Income tax Officer (2); This Court has laid down that a classification made by the	 State will be reasonable provided that (1) it is founded on an intelligible differentia which distinguishes persons or things that are grouped together from other left out of the group; and (2) that the differentia has a rational relation to the object sought to be achieved by the statute. In the State of Madhya Pradesh vs Gwalior Sugar Co. Ltd. (4); it has been held that it is permissible to make classification on historical grounds	 by putting in one class one set of persons or things and in 'other all those left out from the first class Court. In Ramjilal vs Income tax Officer	 Mohindargarh(5) this Court has held that a taxing law may provide that a law imposing a new rate shall not apply to pending proceedings. In other words this Court has upheld the law where one rate of income tax shall be applicable to persons whose cases were pending for assessment and another rate to persons whose cases were not so pending. Thus	 this Court has hold as reasonable classification made by reference to difference in time. In Sardar Inder Singh vs The State of Rajasthan (6) this Court has held that it is open to the legislature to decide the date from which a law should be given operation and that the law made by it cannot be challenged as discriminatory because it (1) ; (2) ; (3) C A. Nos. 98 & 98 of 1959 decided on November 30	 1960. (4) ; (5) ; 952 does not apply to prior transactions. Thus in this case also classification made on the basis of difference in time has been upheld. Finally in Hathising Mfg. Co. vs Union of (India (1) this Court has held that there is no discrimination if the law applies generally to all persons who come within its ambit as from the date on which it is made operative. This case likewise accepts that it will not amount to discrimination if one set of persons is treated differently from another by reference to a point of time. It would follow from these decisions that if the State as an employer provided that persons entering its service after a certain date will be governed by a set of condition which will be different and	 may be less favourable than those governing the existing entrants that law will not be open to attack under article 14 of the Constitution on the ground that it discriminates between one set of employees and another. In my judgment the principle laid down by this Court that reasonable classification does not amount to discrimination is of general application. Therefore	 when an employer 's action is challenged before an Industrial Tribunal as discriminatory	 the Tribunal will also have to bear it in mind. For if an action cannot be regarded as discriminatory and violative of article 14 of the Constitution because it is based on a reasonable classification an identical action of a private employer affecting his employees can also not be regarded as discriminatory. The content and meaning of 'discrimination '	 wherever the term is used	 must necessarily be the same and we cannot adopt one standard for judging whether an action when it emanates from the State	 is discriminatory or not and another standard for judging an identical action	 when it emanates from a private citizen. Looked at this way	 I have no doubt that the Trust has not practised what can in law be regarded as discrimination against its now entrants (1) A.I.R. 1960 S.C. 931. 953 by allowing them lesser leave than it has allowed to its old entrants. I may point out that it is not an unusual thing even in Government service to find new entrants being treated differently in the matter of leave	 emoluments etc.	 from the old entrants. It is a well know fact that in most of the provinces of India in the year 1932 or 1933 pay scales in various categories of Government service were revised and new scales less favourable than the old ones were introduced. Therefore	 a largo body of men were performing the same duties as other large body of men but were getting lesser pay than the latter. That happens often	 is happening today in several of the recently reorganised States and may happen hereafter also. But merely because new terms of service are less favourable than the old ones	 would it be correct to say that there is discrimination between the new entrants and the old entrants? As already pointed out	 it is open to the employer to offer different and even less favourable terms to new entrants and if the new entrants entered service with their eyes wide open they cannot reasonably complain of being discriminated against. Mr. Ramamurthi who appears for the employees	 however	 contends that it is open to an employee to take up employment on the existing conditions of service and immediately start clamouring for improving his conditions of service. It is sufficient to say that without establishing that there was a change in circumstances subsequent to the time when a workman accepted service a demand for improvement in the conditions of service cannot	 with justice	 be entertained unless of course the original conditions of service were plainly unfair. Mr. Ramamurthi does not say that the term regarding leave in the rule applicable to the new entrants is unfair in the sense that the 954 leave allowed is inadequate. But	 Mr. Ramamurthi said that where a service condition causes heartburning amongst two sections of employees discontent and unrest would be its natural outcome and so it is open to the Tribunal to revise the condition and thus eliminate that discontent. I am unable to accept the argument. No doubt	 the provisions of the Industrial Disputes Act are wide enough	 like those of other legislative enactments placed on the statute book	 for promoting the welfare of the employees to permit an Industrial Tribunal to override the contract between an employer and his employees governing conditions of service of the employees. But it does not follow from this that no sooner a reference of a dispute is made to a Tribunal for adjudication than the contract of service ceases to have any force. The power to interfere with a contract of service can only be resorted to in certain limited circumstances. As has been pointed out by this Court in State of Madras vs C. P. Sarathy(1)	 the adjudication by a Tribunal is only an alternative form of settlement of disputes on a fair and just basis	 having regard to the prevailing conditions of the industry. Bearing in mind this principle	 it would follow that it is only for securing a fair and just settlement of an industrial dispute that the Tribunal can over ride the contract between the parties. For deciding what is fair and just	 it is not enough for the Tribunal to say that a particular demand be granted for doing social justice. What it must ascertain is whether the grievance is a real one and whether it is of a type of which the employees can justly complain. In Muir Mills Co.	 Ltd. vs Suti Mills Mazdoor Union	 Kanpur (2) it has been pointed out social justice is a very vague and indeterminate expression and no clear cut definition can be laid down which will cover all the situations and that the fancy of an (1) (2) ; 955 individual adjudicator is not social justice. But	 of course. 	 that does not mean that social justice has no place in the settlement of industrial disputes. It is indeed a relevant consideration but it is well to bear in mind that doing social justice in an industrial dispute is not merely doing justice between the employer and the employee. The question of doing anything in the interest of social justice comes in when the State has a social interest in a situation or in an activity because of its repercussions on the community at large. Therefore	 when the social interest of the community is involved in a situation or an activity	 the interests of all parties who are affected by it have to be borne in mind	 the parties being not merely the employers and the employees but also the community at large which includes also the consumers. So	 where a direction in an award is sought to be sustained on the ground that it was made with the intention of promoting social justice it must be shown that the adjudicator had borne in mind also the interests of the community. This aspect of the matter has not been borne in mind by the Tribunal and	 therefore	 the relevant direction in its award cannot be sustained on the ground that it is actuated by the need of promoting social justice. The ground given by the Tribunal	 as already stated	 is that there is discrimination and the existence of the discrimination will be a perpetual source of unrest. Granting	 again	 that there is discrimination it is difficult to appreciate now it can be a perpetual source of bitterness for. with the efflux of time	 the old employees will gradually be fading out till at last there will be left only that category of workers to which the provisions of is. 79 of the apply. 956 Nor again. do I think the fact that a dispute a comparatively of minor character and that the financial burden entailed on the employer is inconsiderable	 a matter which would entitle the Tribunal to alter a contract between an employer and his employees. In fact these factors are not relevant for consideration. If the leave terms offered to new employees were on their face unfair	 the mere fact that the employer did not have the capacity to pay would not have been allowed to influence the determination of the issue. I would go further and say that since the Trust has provided for its new entrants such leave facilities as are recognised by the itself as fair	 it was not open to the Tribunal to revise the relevant term of the contract	. For all these reasons I am of opinion that the appeal must succeed and the award of the Tribunal should beset aside in so far as it refers to the demand made by the employees for grant of the same leave to new entrants as is being granted to old employees. By COURT. In accordance with the opinion	 of the majority	 the appeal fails and is dismissed with costs.

On July 1	 1956	 the appellants made a rule that every workman employed on or before that date would be entitled to 30 days leave with wages after working for II months and workmen employed after that date would be entitled to earned leave in accordance with the provisions of s.79 of the Indian . The State Government referred for adjudication to the Industrial Tribunal the question whether all the employees should be allowed 30 days earned leave with full wages for every II months ' service without discrimination. The Tribunal held that ail the workmen were entitled to 30 days earned leave without making any distinc tion between workmen who joined before July 1	 1956	 and those who joined subsequently. The appellants contended that they were entitled to fix the terms of employment on which they would employ the workmen and it was open to the workmen to accept those terms or not and the tribunal was not justified in interfering in such a matter. Held	 per Gajendragadkar and Das Gupta	 JJ.	 that the Tribunal was justified in directing the appellants to provide for the same uniform rule as to earned leave for all their employees. The doctrine of absolute freedom of contract had to yield to the higher claims for social justice and had to be regulated. In industrial adjudication no attempt should be made to answer questions in the abstract for evolving any general or inflexible principles. Each dispute has to be decided on its own facts without enlarging the scope of the enquiry. If some principles have to be followed or evolved	 care has to be taken not to evolve larger 931 principles. In order that industrial adjudication should be free from the tyranny of dogmas or the sub conscious pressure of preconceived notions it is important that the temptation to lay down broad principles should be avoided. Accordingly it is not necessary to decide the broad contention whether industrial adjudication can interfere with the contract between the employers and the employees. In the present case	 all the workmen were governed b the same terms and conditions of service	 except in regard to earned leave. The discrimination was not based upon any principle and was bound to lead to disaffection amongst the new employees. The financial burden imposed by the award on the employers was slight. The provisions for earned leave in respect of old employees were not unduly generous or extravagant. Earned leave provided for by s.79 was the minimum statutory leave. If the appellants thought it necessary to provide for additional earned leave for their old employees	 there was no reason why they should not make a similar provision in respect of new employees as well. Western Indian Automobile Association vs Industrial Tribunal	 Bombay	 and Bharat Bank Ltd. vs The Employees of Bharat Bank Ltd. 	 referred to. Per Mudholkar	 J. The Tribunal was not justified in interfering with the rule made by the appellants. It was open to the appellants to grant leave according to s.79 	 to all the employees but still they did not wish to reduce the leave of 30 days which they were already giving to the old employees. The appellants have put into one category persons who enjoyed the same kind of benefits until July 1	 1956	 and have put in another category persons who did not enjoy such benefits. All persons in each category were treated alike	 and the question of dis crimination did not in fact arise. If the State had pro vided that persons entering its service after a certain date would be governed by a set of conditions which were different and less favorable than those governing the existing servants its action would not be open to an attack under article 14 of the Constitution. An identical action of a private employer could also not be regarded as discriminatory. An award made with the intention of promoting social justice must take into consideration the interests of the community. Even if there was discrimination it could not be a perpetual source of bitterness as gradually the old employees would fade out 932 till only one category of workers would remain. The facts that the dispute was comparatively of a minor character and that the financial burden imposed on the appellants was small did not entitle the tribunal to alter the contract between the employer and employees. Since the appellant had provided for its new entrants such leave facilities as were recognised by the itself as fair	 it was not open to the Tribunal to revise the relevant term of the contract.
