Subsequently, the government have issued orders in G.O.Ms.No.166 Directorate of Municipal Administration and Water Supply (M.E.III) Department dated 26. 1999 amending Tamil Nadu Municipal Engineering and Water Works Service Rules, 1970. In Class VIII, after category 7, the government have included category 8-Wireman and category 9-Wireman Helper were inserted and the Tamil Nadu Municipal Engineering and Water Works Service Rules, 1970 were suitably amended. 1999 amending Tamil Nadu Municipal Engineering and Water Works Service Rules, 1970.

The qualifications for the post of wireman in category VIII are a pass in X standard Examination conducted by the Tamil Nadu Board of Secondary Education and Industrial Training Institute (Wireman Trade) Certificate awarded by the National Council for Training Vocational Trades of Government of Tamil Nadu. The qualification for the post of wireman helper is a pass in VIII standard. The method of recruitment to the post of wireman is by direct recruitment. Admittedly, the qualifications prescribed for the post of wireman, the method of recruitment etc. have been changed after the amendment to the rules issued in G.O.Ms.No.166 Directorate of Municipal Administration and Water Supply (M.E.III) Department dated 26. 1999 the amendments to the Tamil Nadu Municipal Engineering and Water Works Service Rules have not been challenged. It is well settled that any executive instructions issued in the matter of filling up of a post can be followed till the formulation of recruitment rules applicable to the said post. Rules framed under Act 309 of the Constitution of India will prevail over administrative/executive instructions. Useful reference can be made. Subash v. State of Maharashtra (1995) supp 3 SCC 332, where the Supreme Court held that circular cannot replace the rules framed under Article 309 of the Constitution of India. In K. Kuppusamy v. State of T.N. (1998) 8 SCC 469 , the Apex Court held that rules framed under Article 309 cannot be overridden by executive orders or executive practice. .7. In the case on hand, though the vacancies arose in the year 1998, the department have started the process of recruitment only in the year 1999, by which time, the qualification for the post of wireman has been changed from 8th standard to that of a pass in the X Standard Examination conducted by the Tamilnadu Board of Examination and Industrial Training (Wireman Trade) Certificate awarded by the National Council for Training in Vocational Traders or from the Government of Tamil Nadu. It is not in dispute that the petitioners did not possess the prescribed qualifications for the post of wireman. It is not in dispute that the petitioners did not possess the prescribed qualifications for the post of wireman. The contention of the learned counsel for the petitioner that the respondents ought to have followed the circular memorandum dated 9. 1989 for filling up the posts of wireman in the year 1998 instead of applying G.O.Ms.No.166 Directorate of Municipal Administration and Water Supply (M.E.III) Department dated 26. 1999, cannot be countenanced in law for the reason it is for the department to recruit people depending on the need for filling up the posts, administrative exigency etc. Merely because there were some vacancies in 1998, it cannot be said that the government ought to have filled up the posts immediately by resorting to the method of recruitment prescribed in the circular stated supra. Though it is contended that the first respondent, Commissioner of Mayiladuthurai Municipality had sent a proposal for filling up the vacant posts, it is open to the Head of the Department and the government, respondents 2 and 3 to give appropriate directions to be followed in the matter of filling up the posts. 8. In P.U. Joshi and Others v. Accountant General Ahmedabad and Others (2003) 2 SCC 632 at paragraph 10 of the judgment, the Supreme Court held as follows: “questions relating to the constitution, pattern, nomenclature of posts, cadres, categories, their creation/abolition, prescription of qualifications and other conditions of service including avenues of promotions and criteria to the fulfilled for such promotions pertain to the field of policy is within the exclusive discretion and jurisdiction of the State, subject, of course, to the limitations or restrictions envisaged in the Constitution of India and it is not for the statutory Tribunals, at any rate, to direct the Government to have a particular method of recruitment of eligibility criteria or avenues of promotion or impose itself by substituting its views for that of the State. Similarly, it is well open and within the competency of the State to change the rules relating to a service and alter or amend and vary by addition/subtraction the qualifications, eligibility criterial and other conditions of service including avenues of promotion from time-to–time, as the administrative exigencies may need or necessitate. Similarly, it is well open and within the competency of the State to change the rules relating to a service and alter or amend and vary by addition/subtraction the qualifications, eligibility criterial and other conditions of service including avenues of promotion from time-to–time, as the administrative exigencies may need or necessitate. Likewise, the State by appropriate rules is entitled to amalgamate departments or bifurcate departments into more and constitute different categories of posts or cadres by undertaking further classification, bifurcation or amalgamation as well as reconstitute and restructure the pattern and cadres/categories of service, as may be required from time to time by abolishing the existing cadres/posts and creating new cadres/posts. There is no right in any employee of the State to claim that rules governing conditions of his service should be forever the same as the one when he entered service for all purposes and except for ensuring or safeguarding rights or benefits already earned, acquired or accrued at a particular point of time, a government servant has no right to challenge the authority of the State to amend, alter and bring into force new rules relating to even an existing service.” 9. In view of the above, the direction sought for by the petitioners to consider their case for promotion to the post of wireman notwithstanding G.O.Ms.No.166 Directorate of Municipal Administration and Water Supply (M.E.III) Department dated 26. 1999 cannot be granted. Record of proceedings in this Original Application shows that at the time of admitting the Original Application, the Tribunal by its order dated 9. 1999 had directed the posts of wireman in Mayiladuthurai Municipality to be kept vacant and the interim order continued thereafter. Since the petitioners are not entitled to the relief sought for in the writ petition, the interim order granted is vacated. It is open to the respondents to fill up the vacancies, if they so desire in accordance with the recruitment rules in force. 10. In the result these writ petitions are dismissed. No costs.
