Summarize the following court judgment. been clearly mentioned that they shall be deemed to have been made ap plicable from 1st April	 1974. The Board had set up 280 their case in the reply to the writ petition on the basis of these Regulations and it was the duty of the Division Bench of the High Court to have looked into the reply filed by the Board and to decide the effect of such statutory regulations in the present case. [291D E] (5) The High Court committed a serious error in ignoring clause IX of the First Settlement dated 22.2.1972 as well as the Regulations made by the Board in 1978. [291H] & CIVIL APPELLATE JURISDICTION: Civil Appeal No. 2917 of 1985. WITH Civil Appeal Nos. 2900 2901	 2903 2916 of 1985 and 2918 21 of 1985. From the Judgment and Order dated 21.5.1984 (Judgment pronounced on 2.7. 1984) of the Rajasthan High Court in D.B. Civil Special Appeal No. 172 of 1984. Dr. L.M. Singhvi	 Sushil Kumar Jain	 Shahid Rizvi	 Dr. D.K. Singh	 Pradeep Agarwal	 Pratibha Jain and Sudhanshu Atreya for the Appellants. Rajinder Singhvi	 M.R. Singhvi and Surya Kant for the Respondents. The Judgment of the Court was delivered by KASLIWAL	 J. All these civil appeals by special leave are directed against the Judgments of the Rajasthan High Court dated May 11	 1984	 May 21	 1984 and the reasons whereof pronounced on 2.7. Controversy raised in all these cases is whether the respondents are entitled to pay scale No. 2 or pay scale No. 3. The Government of India vide its Resolution dated 20th May	 1966 constituted a General Wage Board for electricity undertakings for evolving wage structure	 specialisation of nomenclature and job description. The recommendations of the said Wage Board were accepted by the Government of India in July	 1970. The Prantiya Vidyut Mandal Mazdoor Federation (in short the Federation) recognised trade union of the employees of the Rajasthan State Electricity Board presented their demands before the Labour Department of the 281 Government of Rajasthan for implementation of the recommen dations of the Wage Board. While the said industrial dispute between the management of the Board and its employees was pending before the Conciliation Officer	 a settlement was arrived at on February 22. By this agreement the parties agreed that the existing scale of pay of various categories of posts would be revised w.e.f. 1st April	 1969. The schedule of the said agreement set out various catego ries of posts under different pay scales. At St. No. 21 Meter Reader/Meter Checker was mentioned under scale No. 3 i.e. Rs. 126 8 150 10 250. In pursuance to the above settle ment the Board issued a notification dated 22nd March	 1972 revising the pay scales of its employees w.e.f. 1st April	 1969. Subsequent to this agreement the Board entered into another agreement with the Federation on December 2	 1972 (hereinafter referred to as the Second Settlement). In the second settlement. it was mentioned that this was done in view of some anomalies and difficulties which had cropped up in the course of implementation of previous agreements dated January 26	 1970; April 27	 1971; and July 28	 1972. It was also mentioned in the said settlement that it was considered desirable to remove the anomalies and clarify certain points by mutual negotiations. The settlement was made effective w.e.f. 1st April	 1968. In the second settlement it was agreed to have two categories for Meter Readers i.e. Meter Reader I/Meter Checker I and Meter Reader II/Meter Checker II. The relevant Clause in this regard reads as under: "II. Under pay scale No. 3 technical read 21" Meter Reader I/Meter Checker I and under pay scale No. 2 technical	 insert "7 Meter Reader /I/Meter Checker II" and insert the following Note below pay scale No. 2: "Meter Reader II/Meter Checker II appointed/fixed	 pro moted/adjusted on or before 31.3. 1968 will be fixed in pay scale No. 3 instead of pay scale No.2. The Board in accordance with the second settlement issued another Notification dated 6.12. 1972 whereby the previous Notification dated March 22	 1972 was amended. Some of the employees	 namely	 Jagdish Prasad	 Brij Mohan	 Madho Singh	 Prakash Chander	 section Samuel	 Brij Lal and Chander Bhan filed writ petitions in the High Court of Judicature for Rajasthan at Jodhpur and challenged the Notification dated 6th December	 1972. It may be noted that all these employees were appointees before 6.12. Learned Single Judge of the High Court by Judgment dated 21st March	 1979 allowed the write 282 petitions and quashed the Notification dated 6th December	 1972 mainly on the ground that the second settlement could not have been made as no conciliation proceedings were pending before such settlement and that the date 1.4.1968 mentioned in the notification for making the settlement effective was arbitrary and without basis. The Board filed on appeal before the Division Bench which by their judgment dated 19th December	 1979 dismissed the same and upheld the judgment of the Learned Single Judge. The Board implemented the judgment of the High Court in respect of Jagdish Prasad & Ors. and issued orders to provide scale No. 3 to all Meter Readers appointed upto 6.12. After 6th December	 1972 some more persons were appoint ed on the post of Meter Reader/Meter Checker Grade II i.e. in the pay scale of Rs.80 5 110 6 152 7 194 between the period 1972 1979. Some of the employees again filed writ petitions in the High Court. The High Court vide its judg ment dated 29th March	 1982 allowed the writ petitions on the ground that the second settlement had already been quashed by the earlier judgment given in Brij Lal vs Rajas than State Electricity Board	 [1979] WEN UC 221. The High Court inter alia held and observed as under: "Once the second settlement dated December 6	 1972	 no longer exists in view of non compliance with Section 19(2) of the aforesaid Act and in view of the decision of this Court in Brijlal 's case (supra)	 the only settlement which can be said to be in existence is the first settlement dated February 22	 1972. The aforesaid settlement only provides one grade (scale No. 3 item No. 21) for Meter Reader/ Check er	 and	 therefore	 the petitioner is entitled to be fixed in that grade. Merely because the post of Meter Reader II/Checker II was advertised with pay scale No. 2 and the petitioner applied and was selected	 it cannot be said that the petitioner is estopped now from challenging his fixation in the aforesaid pay scale. There can be no estoppel against statute. The petitioner was not knowing and could not know that it is the first settlement dated February 22	 1972 which was in force and the settlement dated December 6	 1972 was invalid	 and	 therefore	 no case of estoppel is made out against the petitioner. Once this Court had quashed the second settlement dated December 6	 1972 and held that the first settlement 283 dated 22	2	 1972 Was in force	 it Was necessary for the Board to have fixed the Meter Reader/Meter Checker in scale No. 3 item No. 21 of Schedule 'A ' to the first settlement. The Board in spite of demand made to it by the petitioner in this behalf refused to do it". A bunch of 35 identical writ petitions directing the Board to fix the petitioners in the pay scale No. 3 (Rs. 126 250) as revised from time to time were allowed by learned Single Judge of the High Court by a common order dated November 15	 1983. The Board filed special appeals before the Division Bench. The Division Bench dismissed the special appeals by orders dated 11.5.1984	 21.5.1984 and observed that the reasons will be recorded later on. The Division Bench thereafter pronounced the reasons by order dated 2.7. The Board has now filed these appeals restricted to such employees who were appointed as Meter Readers/Checkers grade II after 1.4.1974. It may also be mentioned at this stage that under Clause IX of the first settlement dated 22nd February	 1972 it was mentioned as under: "(IX) This agreement shall remain in force upto 31st March	 1974 and the Federation agrees not to raise any demand in respect of any of the matters covered by this agreement during the period of the operation of the agreement". It may also be mentioned that in exercise of the powers conferred by Section 79	 sub sec. (c) and (k) of the Elec tricity (Supply) Act	 1948	 the Board after obtaining con currence of the Government of Rajasthan and directives issued under Sec. 70(A) of the said Act and taking into consideration the suggestions made by the representatives of the employees	 made regulations which are called Rajasthan State Electricity Board Employees (emoluments) Regulations	 1978. These regulations were made applicable retrospectively from 1st April	 1974. Under these regulations post of Meter Reader II/Meter Checker I1 was mentioned in scale No. 2 as revised in the pay sclae of Rs.260 8 324 10 464. Dr. L.M. Singhvi	 St. Advocate appearing on behalf of the Board contended that irrespective of the earlier judg ment given by the High Court in Brij Lal vs R.S.E.B. (supra) quashing the second notification dated 6.12.1972 the present appeals having been filed against the Meter Readers appoint ed on or after 1.4.1974	 they are not entitled to scale 284 No. 3 as the first settlement dated 22.2. 1972 was to remain in force upto 31st March	 1974. It was also argued that in the appointment orders of the respondent employees appointed after 1.4.1974	 it was clearly mentioned that they were appointed as Meter Reader/Meter Checker II in pay scale No. 2 i.e. Rs.80 194. Dr. Singhvi further argued that the Board had also made regulations which had statutory force and were made applica ble retrospectively from 1st April	 1974. Under these regu lations also the post of Meter Reader II/Meter Checker II was mentioned in Scale No. 2. It was thus contended that considering the matter from any angle	 the respondents were not entitled to scale No. 3 but were only entitled to scale No. 2 as revised from time to time. It was also pointed out by Dr. Singhvi that without prejudice to the above submis sions so far as respondents Laxman Lal	 Sita Ram and Madhay Lal are concerned	 they were otherwise also not entitled to get any relief in as much as they were appointed Meter Readers II after the notification of the Regulations of 1978. The Regulations were notified vide notification No. RSEB. F. RRBS/D.41 dated 4th May	 1978 whereas Laxman Lal	 Sita Ram and Madhay Lal were appointed respectively on 19th August	 1978.8th October	 1979 and 9th April	 1979. Learned counsel for the respondent employees on the other hand submitted that in the settlement dated February 22	 1972 no distinction was made of Meter Reader Gr. I or II and the post of Meter Reader/ Meter Checker was placed in pay scale No. 3. It was submitted that validity of second settlement and the notification dated December	 6	 1972 was challenged in Brij Lal 's case and a Division Bench of the High Court had quashed the aforesaid settlement and the said judgment was not challenged by the Board before this Hon 'ble Court and the same had become final. Thereafter an arbitra tion award was given in 1979 between the Board and the Federation under which two categories of Meter Readers/Meter Checkers were again made. According to this award Meter Reader/Meter Checker II was placed in the pay scale No. 2 of Rs.80 194 and Meter Reader/Meter Checker I was placed in the pay scale of No. 3 of Rs. 126 250. It was thus submitted that all the Meter Readers appointed upto 1979 were entitled to scale No. 3. It was further submitted that the first settlement dated February 22	 1972 and the notification issued thereafter on March 22	 1972 continued to operate and there was only one pay scale of Rs. 126 250 for all Meter Readers and there being no classification of Gr. I or II	 the pay scale of Rs. 126 250 remained in force	 till the arbitration award was given on June 15	 1979. It was submit ted that all the respondents having been 285 appointed prior to June 15	 1979	 they were entitled to pay scale No. 3. As regards the stand taken by the Board that it had framed Regulations regarding the fixation of pay scales it was contended that no such plea was taken in reply to the writ petitions filed by the employees. It was pointed out that the contention with regard to the first settlement having come to an end on March 31	 1974 as well as the contention raised on the basis of regulations was rightly negatived by the Division Bench of the High Court in the following manner: "It was contended by the learned counsel for the appellants that the learned Single Judge did not take into considera tion the fact that first settlement came to an end on March 31	 1974 and was not in force after that date. He submitted that the Board had powers under Sec. 79(c) and (k) of the to frame Regulations regard ing the fixation of pay scales. Learned counsel for the appellants was asked to show from the writ petitions whether this point was taken in the writ petitions or not. Learned counsel for the appellants candidly admitted that it was not raised in the writ petitions filed by the petitioners. It was	 then. put to the learned counsel whether this point was argued before the learned Single Judge. Mr. S.N. Deedwania submitted that in the absence of the affidavit of the coun sel who argued on behalf of the appellants before the learned Single Judge positive assertion to that effect cannot be made. In the memo of appeal this ground	 of course	 has been taken but not in the manner in which it has been stated hereinabove. As this point was not taken in the writ peti tions and it was not argued before the learned Single Judge	 we do not consider it necessary to examine it. We shall examine the validity of the order under appeal on the basis of the grounds that were argued on behalf of the petitioners before the learned Single Judge". It was further contended that during the pendency of these appeals additional affidavit was filed on behalf of Laxman Lal respondent. It was pointed out in the additional affidavit that Sh. Udai Lal and Sh. Shyam Lal were appointed as Meter Readers vide order dated 6.9.1974. These persons filed writ petitions Nos. 1191/81 and 1181/81 respectively. The aforesaid writ petitions were allowed by the High Court vide judgment dated 28.3.1982. One Sh. Prem Shankar who was appointed as Meter Reader vide order dated 16.5. 1974 also filed a writ petition 286 No. 120/81 in the High Court and it was also allowed by order dated 28th March	 1982. The Board did not challenge the aforesaid orders and issued order on 23.8.1982 imple menting the judgment of the High Court. The above examples were given in order to show that these persons were also appointed after 1.4.1974 and in their cases also relief was granted by the High Court and the Board never challenged the aforesaid judgments given in favour of Udai Lal	 Shyam Lal and Prem Shankar. It has also been submitted that the Board has also published a revised revenue manual on 1.9. 1986 in which vide para 124 duties of Meter Readers have been laid down. It is contended that in the manual no dif ferent duties have been prescribed for Meter Reader II and Meter Reader I and thus in the discharge of duties there is no difference. A supplementary affidavit has been filed by Shri R.C. Harit	 Deputy Director	 Rajasthan State Electricity Board. It has been submitted in the supplementary affidavit as under: "That is so happened that after the aforesaid judgment dated 19th December	 1979 in the matter of R.S.E.B. vs Jagdish Prasad Brij Lal D.B. Appeal No. 179 of 1979 some other Meter Readers on the basis of this judgment filed various other writ petitions. In these writ petitions the question above the applicability of Regulations or the question as to whether the Respondent can challenge his own appointment by which they were appointed to Meter Reader II post were not at all raised or decided by the High Court. The High Court decided the said writ petitions only on the basis of the earlier judgment in the matter of R.S.E.B. vs Jagdish Prasad (Brij Lal). The Appellant Board implemented the said order. The respondent is trying to raise the said question which was neither been decided by the High Court and has been raised for the first time in this supplementary affidavit. On account of lapse of time	 the appellant is finding it difficult to give reply. The Deponent has tried his best to locate the records but in such a short period he could not get the file of the case which was decided about eight years back as it appears to have been mixed up in the old record. That the order passed in the matter of Shanti Lal was a Judgment inter parties and	 therefore	 simply because the Board did not challenge the said order	 it does not mean that the respondent can also take advantage of the same and can raise the question of equal pay for equal work. In this the 287 Appellants further state that all the persons except re spondent Shri Lehar Singh and Gharsi Lal (Geharial) in civil appeal in the present case were appointed after 7th Septem ber	 1974 and 16th May	1974 i.e. the date on which three persons whose matters were decided alongwith Shanti Lal 's case were appointed" We have thoroughly examined the record and have consid ered the arguments advanced b.y Learned counsel for the parties. It may be noted that all the above appeals are in respect of such employees who were appointed after 1.4.1974. In the appointment orders of all the respondents it was specifically mentioned that they were appointed as Meter Reader Gr. II in the pay scale of Rs. 80 194 (subsequently revised to Rs. 260 464). In Clause (ix) of the First Settle ment dated 22nd February	 1972 it was clearly mentioned that this agreement shall remain in force upto 31st March	 1974. The stand taken by the Board all along was that this settle ment was subsequently amended by another agreement (Second Settlement) on December 2	 1972. In this second Settlement certain anomalies and difficulties had cropped up in the course of implementation of earlier settlements and hence some clarifications were made by mutual negotiations. The clarifications relevant for our purpose were that the First Settlement was made effective w.e.f. 1st April	 1968 instead of 1st April	 1969 and two categories were fixed for Meter Readers i.e. Meter Reader I/Meter Checker I and Meter Read er II/Meter Checker II. Necessary amendments were made in the Schedules annexed to the Settlement according to which under pay scale No. 3 at Item No. 21 Meter Reader I/ Meter Checker I and under pay scale No. 2 at Item No. 7 Meter Reader II/Meter Checker II were inserted. This Second Set tlement was subsequently notified by a Notification dated 6.12. According to the Board this Second Settlement was merely a clarification settlement and not a new settle ment in as much as it sought to make clear the ambiguity which had cropped up in the First Settlement in the matter of fixing the grades and pay scales of the Meter Readers/Meter Checkers. The Notification dated 6.12.1972 which related to the Second Settlement dated 2.12.1972 was challenged by some of the employees by filing writ petitions in the High Court and Learned Single Judge by Judgment dated 21st March	 1979 allowed the writ petitions and quashed the notification dated 6th December	 1972. It may be noted that the Second Settlement was quashed on the ground that the Second Settlement could not have been made as no concilia tion proceedings were pending before such settlement and the date 1.4.1968 mentioned in the Notification was arbitrary and without any 288 basis. An appeal filed by the Board against the aforesaid decision was dismissed by the Division Bench of the High Court on 19th December	 1979. This litigation was commenced by such employees who were appointed prior to 6.12.1972. Subsequently employees appointed between the period 1972 1979 filed writ petitions in the High Court. The stand taken by these employees was that the Notification dated 6.12. 1972 had already been quashed by the High Court and as such they were to be governed by the First Settlement dated February 22	 1972 in which there was only one category Of Meter Reader/Meter Checker to whom pay scale No. 3 had been given and as such they were also entitled to pay scale No. 3. The High Court allowed the writ petitions and granted pay scale No. 3 to all the 35 petitioners. the Board has now come before this Court against such employees who were appointed after 1.4.1974. The contention of the Board is that even if for arguments ' sake the earlier decision given by the High Court may be considered as final	 that was in respect of employees who were appointed before 6th December	 1972. As regards the present employees it has been submitted that no benefit can be granted in their case as the First Settlement itself was to remain in force upto 31st March	 1974 and in any case in the appointment orders of the re spondents it was clearly mentioned that they were appointed as Meter Reader/Meter Checker Gr. II in the pay scale No. 2. It has also been urged before us that the Board had made Rajasthan State Electricity Employees (emoluments) Regula tions 1978 published on 4.5. 1978 but the same were deemed to have been made applicable from 1st April	 1974. Under these regulations post of Meter Reader II/Meter Checker II in pay scale No. 2 and Meter Reader I/Meter Checker I have been placed in pay scale No. 3. Learned counsel for the employees respondents contended that though according to Clause IX of the First Settlement dated 22.2. 1972	 it was mentioned that the same will remain in force till 31st March	 1974 yet the same would remain in operation until the expiry of two months from the date on which a notice in writing of an intention to terminate the settlement is given by one of the parties to the other party or parties to the settlement as provided under Sub section (2) of Section 19 of the (hereinafter referred to as the Act). It has been submitted that no such notice was given by the Board and the Second Settlement dated 2.12. 1972 and Notification dated 6.12. 1972 had already been quashed by the High Court in Brij Lal 's case (supra) and the same having become final	 the first settle ment Would govern the parties. Reliance in support of the above contention is placed on The Life Insurance Corporation of India vs D.J. 289 Bahadur and Ors.	 [1980] Lab. I.C. Vol. 2 1218. Our attention was drawn to para 33 of the above case which reads as under: "The core question that first fails for consideration is as to whether the settlements of 1974 are still in force. There are three stages or phases with different legal effects in the life of an award or settlement. There is a specific period contractually or statutorily fixed as the period of operation. Thereafter	 the award or settlement does not become honest but continues to be binding. This is the second chapter of legal efficacy but qualitatively different as we will presently show. Then comes the last phase. If notice of intention to terminate is given under Section 19(2) or 19(6) then the third stage opens where the award or the settlement does survive and is in force between the parties as a contract which has superseded the earlier contract and subsists until a new award or negotiated set tlement takes its place. Like Nature	 Law abhors a vacuum and even on the notice of termination under Sections 19(2) or (6) the sequence and consequence cannot be just void but a continuance of the earlier terms	 but with liberty to both sides to raise disputes	 negotiates settlements or seek a reference and award. Until such a new contract or award replaces the previous one	 the former settlement or award will regulate the relations between the parties. Such is the understanding of industrial law at least for 30 years as precedents of the High Courts and of this court bear testi mony. To hold to the contrary is to invite industrial chaos by an interpretation of the ID Act whose primary purpose is to obviate such a situation and to provide for industrial peace. To distil from the provisions of Sec. 19 a conclusion diametrically opposite of the objective	 intendment and effect of the Section is an interpretative	 stultification of the statutory ethos and purpose. Industrial law frowns upon a lawless void and under general law the contract of service created by an award or settlement lives so long as a new lawful contract is brought into being. To argue other wise i	 to frustrate the rule of law. If law is a means to an end order is society can it commit functional harakiri by leaving a conflict situation to lawless void"? In our view the above Sections 19(2) and 19(6) of the Act cannot give any benefit to the respondents in the fact of the present case. It is not 290 in dispute that the period of the First Settlement was agreed upto 31st March	 1974. The question which calls for our consideration is not the applicability of the First Settlement	 but the real question to be considered is wheth er the Board could have appointed or not the respondents on the post of Meter Reader/Meter Checker Gr. II in pay scale No. 2 after 1.4. The respondents/employees in the present case want to take advantage of the First Settlement simply on the ground that it did not make any mention of Meter Reader/Meter Checker Gr. I or II and it simply made mention of Meter Reader/Meter Checker to whom pay scale No. 3 was given. The above ambiguity was clarified by an agree ment between the Board and the Union representing the em ployees as early as on 2.12. 1972 itself to the effect that Meter Reader/Meter Checker can be placed in two different grades. After this there was no restriction on the Board to make appointment of the Meter Reader/Meter Checker in Grade II after 1.4. That apart there was clear mention in the appointment orders of the respondents that they were appointed as Meter Reader/Meter Checker Gr. II in pay scale No. 2. Learned counsel for the respondents/employees were unable to place any law	 Rule or Regulation of the Board to show that the Board had no power to make such appointments of the Meter Reader/Meter Checker in Gr. The Board had already taken the stand the first settlement was clarified by the second settlement and as such even if the High Court had quashed the second settlement	 it was at least a suffi cient notice within the meaning of Section 19(2) of the Act that the Board had terminated the first settlement after 31.3. The Regulations deemed to have come into force from 1.4.1974 also clearly provided for pay scale No. 2 for Meter Reader/Meter Checker Gr. The Division Bench of the High Court refused to consider the above argument placed on behalf of the Board on the ground that learned counsel for the appellants was asked to show from the writ petitions whether this point was taken in the writ petitions or not and the learned counsel candidly admitted that it was not raised in the writ petitions filed by the petitioners. The High Court further observed in this regard that as this point was not taken in the writ peti tions and it was not argued before the Learned Single Judge	 they did not consider it necessary to examine it. We have already extracted in extenso the observations of the High Court in this regard in the earlier part of the Judgment. There is a complete fallacy	 in the above order in as much as the Board was not the petitioner before the High Court and there was no question of taking any such ground in the writ petitions. In one of the above appeals No. 2901 of 1985 Rajasthan State Electricity 291 Board & Ors. vs Sharad Chander Nagar reply to the writ petition filed by the Board has been placed on record as Annexure 'C '. In the said reply in Para (8) it has been stated as under: "That the contents of Para No. 8 of the writ petition are wrong and denied. The petitioner was not appointed at the time of settlement date 22.2.1972. The Wage Board set tlement dated 22.2.1972	 which was in force upto 31.3. 1974	 and thereafter the Rajasthan State Electricity Board Employ ees (Emoluments) Regulation 1978 was (sic) come into force with effect from 1.4.1974 and wages of all the employees were revised in pursuance of the Rajasthan State Electricity Board (Emoluments) Regulation 1978. The copy of the Board (Emoluments) Regulation 1978 is submitted herewith as Annex ure "B". Apart from the above circumstances of the case the Board in its reply to the writ petition also took the stand that the post of the Meter Reader Gr. I is a promotion post while the post of Meter Reader Gr. II is filled by direct recruit ment. The Rajasthan State Electricity Board (Emoluments) Regulation 1978 made in exercise of the powers conferred by Sec. 79 Sub sections (c) & (k) of the have Statutory force and it has been clearly mentioned that they 'shall be deemed to have been made applicable from 1st April	 1974. The Board had set up their case in the reply to the writ petition on the basis of these Regulations and it was the duty of the Division Bench of the High Court to have looked into the reply filed by the Board and to decide the effect of such statutory regulations in the present case. The Board under Clause (C) of Regulation 79 was fully empowered to provide for the duties of officers and other employees of the Board	 and their salaries	 allowances and other conditions of service or under the residuary clause (k) for any other matter arising out of the Board 's function under this Act for which it is necessary or expedient to make regulations. We have gone through the regulations which have been brought into force from 1st April	 1974 and in Schedule II group 'B ' at Item No. 7 Meter Reader II/Meter Checker II has been fixed in the revised pay scale of Rs.260 464 (original scale Rs.80 194) and in group 'C ' at Item No. 21 Meter Reader I/Meter Checker I in scale No. 3 revised pay scale Rs.370 570 (original scale Rs. 126 250). The High Court committed a serious error in ignoring Clause IX of the First Settlement dated 22.2.1972 as well as the Regulations made by the Board in 1978. 292 So far as the cases of Udai Lal	 Shyam Lal and Prem Shankar are concerned even if the Board did not challenge the order of the High Court dated 28.3.1982 in their cases	 it cannot act as res judicata or as estoppel against the Board in challenging the present order of the High Court before this Court. There is no question of applying the principle of equal pay for equal work in the facts and circumstances of this case and to allow Meter Readers II/Meter Checker Gr. II	 the pay scale of Meter Reader/Meter Checker Gr. I. Apart from that	 these controversies have been raised by the respondents for the first time by filing affidavits before this Court at the fag end of arguments	 and these questions being mixed questions of fact and law	 cannot be permitted to be raised now. In the result	 we allow all these appeals	 set aside the Judgment of the High Court	 and dismiss all the writ peti tions. In the facts and circumstances of the case we direct the parties to bear their own costs. R.S.S. Appeals al lowed.

A settlement was arrived at on 22.2.1972 between the Rajasthan State Electricity Board and the Union representing its employees. In pursuance of this settlement	 notification dated 22.3.1972 was issued revising the pay scales of var ious categories of posts	 effective from 1st April	 1969. As per the settlement	 Meter Reader/Meter Checker was mentioned under scale No. 3. On December 2	 1972 a Second Settlement was entered into between the parties with a view to removing certain ambigui ties in the earlier settlement. In this second Settlement	 notified on 6.12.1972	 it was agreed to have two categories of Meter Readers	 that is	 Meter Reader I/Meter Checker I and Meter Reader II/Meter Checker II. This settlement was made effective w.e.f. 1.4.1968. Some employees appointed before 6.12.1972 challenged the notification dated 6.12.1972. The learned Single Judge of the High Court allowed the writ petitions and quashed the notification mainly on the ground that the Second Settlement could not have been made as no conciliation proceedings were pending before the second settlement. The Division Bench dismissed the appeal filed by the Board. Accordingly	 the Board implemented the Judgment of the High Court and issued orders to provide scale No. 3 to all the Meter Readers appointed upto 6.12.1972. Brijlal vs Rajasthan State Electricity Board	 [1979] WLN (UC) 221	 referred to. During this period	 the State Electricity Board in exercise of the powers conferred by section 79	 sub section (c) and (k) of the made regulations which are cared Rajasthan State 278 Electricity Board Employees (Emoluments) Regulations	 1978. These Regulations were made applicable retrospectively from 1st April	 1974. Under these regulations	 post of Meter Reader II/Meter Checker II was mentioned in scale No. 2. In 1979	 an arbitration award was given between the Board and the union under which two categories of Meter Readers/Meter Checkers were again made. Subsequently	 35 employees appointed between the period 197279 filed the present writ petitions in the High Court. The stand taken by these employees was that the Notification dated 6.12.1972 had already been quashed by the High Court and as such they were to be governed by the First Settlement dated February 22	 1972 in which there was only one category of Meter Reader/Meter Checker to whom pay scale No. 3 had been given and as such they were also entitled to pay scale No. 3. The High Court allowed the writ petitions and granted pay scale No. 3 to all the petitioners. The Division Bench dismissed the special appeal of the Board. The Board has now come before this Court against such employees who were appointed after 1.4.1974. The contentions of the Board before this Court were that (i) even if for arguments ' sake the earlier decision given by the High Court may be considered as final	 that was in respect of the employees who were appointed before 6th December	 1972; (ii) as regards the present employees no benefit could be granted in their case as the First Settle ment itself was to remain in force upto 31st March	 1974; (iii) in any case in the appointment orders of the respond ents it was clearly mentioned that they were appointed as Meter Reader/Meter Checkers Gr. II in the pay scale No. 2; and (iv) under the Rajasthan State Electricity Employees (Emoluments) Regulations 1978	 which were made applicable from 1st April	 1974 Meter Reader II/Meter Checker II have been placed in pay scale No. 2 and Meter Reader I/Meter Checker I have been placed in pay scale No. 3. On behalf of the employees respondents it was connected that (i) though according to Clause IX of the First Settle ment dated 22.2.1972 the settlement was to remain in force till 31st March	 1974 yet the same would remain in operation until the expiry of two months from the date on which a notice in writing of an intention to terminate the settle ment was given by one of the parties to the other party or parties to the settlement as provided under sub section (2) of Section 19 of the ; (ii) that an arbitration award was given in 1979 279 between the Board and the employees federation under which two categories of Meter Readers/Meter Checkers were again made and hence all the Meter Readers appointed upto 1979 before the arbitration award were entitled to scale No. 3	 and (iii) the contention with regard to the first settlement having come to an end on March 31	 1974 as well as the contention raised on the basis of Regulations were rightly negatived by the Division Bench of the High Court as these points were not taken in the writ petitions and were not argued before the learned Single Judge. Allowing the appeals	 this Court	 HELD: (1) The respondents/employees in the present case want to take advantage of the First Settlement simply on the ground that it did not make any mention of Meter Reader/Meter Checker Gr. I or II and it simply made mention of Meter Reader/Meter Checker to whom pay scale No. 3 was given. The above ambiguity was clarified by an agreement between the Board and the Union representing the employees as early as on 2.12.1972 itself to the effect that Meter Reader/Meter Checker could be placed in two different grades. After this there was no restriction on the Board to make appointment of the Meter Reader/ Meter Checker in Grade II after 1.4.1974. [290B C] (2) There was clear mention in the appointment orders of the respondents that they were appointed as Meter Readers/Meter Checkers Gr. II in pay scales No. 2. Learned Counsel for the respondents/employees were unable to show that the Board had no power to make such appointments of the Meter Reader/Meter Checker in Gr. [290D] (3) The Board had already taken the stand that the first settlement was clarified by the second settlement and as such even if the High Court had quashed the second settle ment	 it was at least a sufficient notice within the meaning of section 19(2) of the that the Board had terminated the first settlement after 31.3.1974.
