Judgment :- K. Kannan, J. Petitioners who are third parties to O.A.No. 495 of 2003 have obtained leave for challenging the order dated 9. 2003 passed commonly with O.A.No. 995 of 2002, as affected parties. I. The core issue: 2. The issue centres around interpretation of rule 12 of Customs Department Inspector (Examiner) (Group C posts) Recruitment Rules, 2002 and Rule 5 of Central Excise and Customs Department Senior Tax Assistant (Group C posts) Recruitment Rules, 2003, hereinafter called the Rules of 2002 and Rules of 2003 respectively. The said rules have a bearing on the entitlement to promotion to the post of Inspector, which is an executive cadre. By the impugned order, the Central Administrative Tribunal upheld the contentions of the applicants before it, who were in the technical line of the Excise Department as Data Entry Operators Grade B and C (abbreviated as DEOs Gr B and Gr C), to consider them for promotion to the posts of Inspector alongside the claim of the present petitioners who were in the ministerial cadre in the same Department. II. Phases of cadre re-structuring 3. The computerization ushered in Customs and Excise Department compelled some changes through bifurcation of existing cadre in the late 1980s. The restructuring fell into two streams: (i) Ministerial side and (ii) the Technical side, so called, of persons who were trained in computers. The respondents framed Electronic Data Processing Discipline (Group B Technical Posts) Recruitment Rules, 1992, which saw the constitution of the cadre of persons who were originally appointed as Key punch operators, Terminal Operators and Lower Division Clerks (LDCs) performing their duties as terminal operators but they were deemed to have been appointed as DEOs Gr A and treated as en bloc seniors to those appointed after the commencement of the rules. They were asked to express their willingness on or before 16.03.1993 to be considered for appointment to the post of DEOs Gr A, failing which it was presumed that they were not willing to be considered for the said post. The next higher grades were DEOs Gr B and DEOs Gr C. 4. The 1992 Rules prescribed that all further promotion should be considered only under the said relevant rules and that they would not be considered for promotion to the post as prescribed in the Customs Department Group-C Recruitment Rules. The next higher grades were DEOs Gr B and DEOs Gr C. 4. The 1992 Rules prescribed that all further promotion should be considered only under the said relevant rules and that they would not be considered for promotion to the post as prescribed in the Customs Department Group-C Recruitment Rules. Along with the persons who had made such options, the 5th respondent viz., the Chief Commissionerate of Customs appointed the persons who were performing the duties of Data Entry Operators in various Central Excise Commissionerate on intercommissionerate transfer. In all these processes, the persons who were working as Lower Division Clerks in the Ministerial side chose to remain as such and the next avenue for the promotion to them was Upper Division Clerk (UDC), the Upper Division Clerk Special Grade, UDC Special Pay and Tax Assistants. 5. The next phase of restructuring was done in the year 2002 when on the ministerial side, Assistants, Tax Assistants and UDC (Special Pay) and all the technical side Data Entry Operators Gr B and Gr C were re-designated as Senior Tax Assistants. The next avenue for promotion available to them was to the post of Inspector (Examiners). 6. This phase is the most crucial one when two sets of rules were made which have given rise to a spate of litigations. They were called the Customs Department Inspector (Examiner) (Group C Post) Recruitment Rules, 2002 and Central Excise and Customs Department Senior Tax Assistant (Group C Post) Recruitment Rules, 2003. After the 2003 Rules were notified, a Circular No.41/2003 was issued on 10.06.2003 calling for certain classes of persons who were referred to in Cl (a) of para 12 in 2002 Rules, inviting them to express their willingness to consider them for promotion for the grade of Inspector (examiners) and subject themselves to physical tests. By this Circular, the persons who had been re-designated as Senior Tax Assistant from the technical side, who entered the pre-restructured cadre of DEOs Gr B and C were excluded from reckoning, by the fact that only Tax Assistants, who had put in two years of experience in such post were treated as eligible for being considered for promotion. III. The relevant Rules of 2002 and 2003: 7. III. The relevant Rules of 2002 and 2003: 7. It would be relevant to reproduce the relevant rules and if we have come by an interpretation, which according to us is correct, we would have arrived to the final conclusions to determine the relative merits of the contention of the rival parties. Customs Department Inspector (Examiner) (Group C Posts) Recruitment Rules, 2002:- Central Excise and Customs Department Senior Tax Assistant (Group C Post) Recruitment Rules 2003:- ...... "5. Initial Construction-(i) All the persons appointed on the regular basis at the time of commencement of these rules to the Grade of Assistant, Tax Assistant, Upper Division Clerk (Special Pay), Data Entry Operator Grade B and C shall be deemed to have been appointed as Senior Tax Assistants under these rules. the serviced rendered by them before commencement of these rules shall be taken into account for deciding the eligibility for promotion to the next higher grade. (ii) Assistants (Rs.5000 - 8000) and Data Entry Operator Grade (Rs.5000 - 8000) are being redesignated as Senior Tax Assistants in the same scale of pay. Therefore, the Assistants and Data Entry Operator Grade C shall be placed enblock senior to the other categories. However, their inter-se-placement shall be done according to the date from which they had actually been appointed to these grades on regular basis subject to the condition that their inter se placement in their respective category shall not be altered. (iii) The Date entry Operator Grade B (Rs.4500 - 7000) and Tax Assistants ((Rs.4500 7000) have been placed in their higher scale of 5000 -8000 and they shall be placed below the Assistant and Data Entry Operator Grade C and their inter-se placement shall be fixed in accordance the date of regular appointment to the respective grade subject to the condition that their inter-se placement in respective category shall not be disturbed. .(iv) Upper Division Clerk with special pay shall be placed below Assistant, Date Entry Operator Grade C Data Entry Operator Grade B Tax Assistants. .(v) The present employees would be required to pass the required or suitable departmental examination, as specified by the Competent Authority, from time to time, in Computer application and relevant procedures within two years failing which they would not be eligible for further increments." 8. .(v) The present employees would be required to pass the required or suitable departmental examination, as specified by the Competent Authority, from time to time, in Computer application and relevant procedures within two years failing which they would not be eligible for further increments." 8. The notification of the rules and the circular seemed to contain mutually inconsistent positions which gave rise to the litigations not merely in the State of Tamil Nadu but elsewhere before the Central Administrative Tribunal Benches at Bangalore and Chandigarh, Andhra Pradesh High Court and Bombay High Court. The Central Administrative Tribunal at Bangalore and High Court at Andhra Pradesh High Court interpreted the Rules in such a way that it found only the persons in the ministerial cadre who had attained the position as Tax Assistant, UDC Special Pay and Stenographers Grade-II and Grade III with five years experience as eligible for consideration for promotion to the post of Inspector (Examiners). The Madras Bench of the Central Administrative Tribunal, while quashing the Circular that excluded out of reckoning Data Entry Operators Grade B and C, relied on the decision of Central Administrative Tribunal, Chandigarh Bench, which held that the persons who had been re-designated as Senior Tax Assistant from the technical side were also entitled to be considered for promotion and their experience in the pre-restructured cadre as Data Entry Operators Grade B and C should also be counted. The two streams of opinion have arisen on account of varying interpretation given to the rules of 2002 and 2003. IV. The mode of approach adopted by the Tribunal: 9. This writ petition which examines the decision of the Madras Bench of the Central Administrative Tribunal came about when the Circular No.41/3003 was issued on 10.06.2003 making reference only to para 12 (a) of Rules of 2002 for identifying the class of persons who would be eligible consideration for promotion. In effect, they were excluding for reckoning for promotion the persons who had arrived at the post of Senior Tax Assistant from the technical side. It prompted the persons who had attained Data Entry Operators Grade B and C to challenge the Circular by filing O.A. 495/03 and yet another connected matter filed by the affected parties in O.A.NO.995/02. In effect, they were excluding for reckoning for promotion the persons who had arrived at the post of Senior Tax Assistant from the technical side. It prompted the persons who had attained Data Entry Operators Grade B and C to challenge the Circular by filing O.A. 495/03 and yet another connected matter filed by the affected parties in O.A.NO.995/02. The writ petitioners who were not made parties made a vain bid to implead themselves before the Tribunal and after the common orders were issued in the manner referred to above, they sought to challenge the order in O.A. 495/2003 as deserving to be set aside and for other consequential reliefs. The Tribunal focused its attention to the question that needed to be examined viz. whether the Requirement of Rule of 2002 under column 12 (a) would apply to the exclusion of column 12 (b). If the answer was yes then the Circular was to be upheld and if it was otherwise, the Circular was liable for quashment and the persons who were re-designated as Senior Tax Assistants from the post of Data Entry Operators Grade B and C were not entitled to be considered. .V. Appraisal of the rival contentions: 10. On the first reading of para 12(a) it would seem that the three categories of persons who had been enumerated were alone to be considered since the requirement of two years regular service as Senior Tax Assistant in the grade could not have been available for the persons from the technical Grade since the re-designation of DEO Grade B and C itself was done for the first time only in 2003. Note-I also seemed to provide for promotion for persons in para 12(a) when it limited the consideration of the category only for a period of two years. it was as if the persons in cl(b) were to be eclipsed because none of them could have served as Tax Assistants for a period of 2 years and it was after this gestation that would have made them eligible. it was as if the persons in cl(b) were to be eclipsed because none of them could have served as Tax Assistants for a period of 2 years and it was after this gestation that would have made them eligible. According to the writ petitioners, the two years was a specific limitation in order that the category of persons in para 12(b) gained experience in matters such as subject of law and others subjects relevant for qualifying for the higher post and during that period, only the persons in 12(a) who had gained experience on the ministerial side shall be exclusively considered and after the completion of two years, the persons falling that category in paragraph 12 (b) & (c) could be considered. .11. If the Rules of 2002 were to be considered on a stand-alone basis, it would give rise to such an interpretation that would make the consideration of the Data Entry Operators Grade B and C impossible. Rules of 2003 however creates the fiction which, while describing the initial constitution, states that all the persons appointed on the regular basis at the time of the commencement of the rules as Data Entry Operators Grade B and C, along with others specified therein, shall be deemed to have been appointed as Senior Tax Assistants under these rules and the service rendered by them before the commencement of these Rules shall be taken into account for deciding the eligibility for promotion to the next higher Grade. This rule makes it clear that DEO Grade B and C were entitled to reckon the years of service rendered by them as such before the commencement of the Rules as though they were holding the posts as Senior Tax Assistants. If this were not so, it would be meaningless to allow only for Assistants in the Ministerial grade along with Tax Assistants and UDC Special Scale to be considered when they were all redesignated at the same time as Senior Tax Assistants. The scale of pay of Assistants was Rs.5,000/- to Rs.8,000/-, Tax Assistants scale of pay was Rs.4,500/- to Rs.7,000/- and UDC special pay carried scale of pay of Rs.4000/-to Rs.6500/-. DEO Grade B and C who were in the higher scales of pay at Rs.4,500/- -Rs. 7,000/- would have been left out of consideration, while UDC special pay carrying the scale of Rs.4,000/- to Rs.6500/- would have been considered. DEO Grade B and C who were in the higher scales of pay at Rs.4,500/- -Rs. 7,000/- would have been left out of consideration, while UDC special pay carrying the scale of Rs.4,000/- to Rs.6500/- would have been considered. No rational basis for such an interpretation emerges from examining all the relevant issues. It was only by reading para 12 (a) & (b) along with the rules of 2003 cl 5, it became possible for the Central Administrative Tribunal, Madras Bench to uphold the contention of applicants before it. This was again the reason how the Chandigarh Bench of the Central Administrative Tribunal as well as the Bombay High Court viewed the situation to give it a purposive interpretation to accede to the pleas of Data Entry Operators Grade B and C as falling within the parameters of panel for promotion to the higher grade as Inspectors. The Madras High Court had also found in its judgment dated 13.04.2007 in W.P .No. 8361 of 2004 and batch, with reference to the distinction made between the persons in the Ministerial side aspiring for promotion to Inspectors and from the technical side for similar aspirations, that rules of 2002 themselves betrayed discrimination amongst persons performing similar nature of the duties and struck down the said rules. Although, the decision is reported to have been challenged before the Supreme Court the subsequent development have been that after the Bombay High Court decisions, the Department itself has altered its stand and appears to have considered the persons from the technical side also for promotion without operating para 12(a) exclusively. This is reported to be so for officers in all Divisions except the Madras Division, on account of the pendency of this writ petition. The Department also appears to have originally filed a writ petition challenging the decision of the Central Administrative Tribunal, Madras Bench, but later withdrew it, for the uniform application of promotion to both the categories after the decision of the Bombay High Court was confirmed in SLP before the Supreme Court. .12. Considering not merely the case on its merits to arrive at this conclusion, we have the satisfaction of seeing that the benefit of interpretation that the Department itself has made on an All India basis, other than for Tamil Nadu, shall enure for their benefit as well and place them at par. .Conclusion: 13. .12. Considering not merely the case on its merits to arrive at this conclusion, we have the satisfaction of seeing that the benefit of interpretation that the Department itself has made on an All India basis, other than for Tamil Nadu, shall enure for their benefit as well and place them at par. .Conclusion: 13. In the circumstances, we find that the decision of the Central Administrative Tribunal, Madras Bench, accords with law and dismiss the writ petition filed by the petitioners. There shall be no order as to costs. Consequently, connected miscellaneous petition is closed.
