Judgment Satish K. Agnihotri, J. 1. Indisputably, the writ petitioner/first respondent herein joined the service in the Central Prison, Chennai as Warder Grade-II on 15.3.1966. The writ petitioner's appointment was made against reserved category as on that day, the writ petitioner belonged to Scheduled Caste (Pallan community). His appointment was regularised with effect from 1.8.1967. It is stated that during service, the petitioner adopted the Christianity religion. There is no dispute that a Scheduled Caste candidate on conversion does not continue to be the Scheduled caste, but is treated as Backward Class community in the State of Tamil Nadu. 2. At the time of appointment, the writ petitioner's height was 160 cm and 79-84 cm chest measurement, as required. However, for the member of Backward class, the height requirement is 168 cm and chest is 81-86 cm. The writ petitioner was promoted to the post of Warder Grade-I with effect from 2.9.1976. Thereafter, he was appointed temporarily on the post of Chief Head Warder. It was discovered by the authorities that after joining the service, he had converted to Christianity and as such, it was observed that the writ petitioner did not possess the requisite physical qualification for regularisation and also for further promotion to the higher post. 3. The writ petitioner made a representation dated 16.8.2000 for regularisation after relaxing the rules on the basis of the initial appointment, which was rejected on the ground that even the writ petitioner's appointment on the post of Warder Grade II was not proper as the writ petitioner did not have the requisite physical qualification, i.e., 168 cm height and 81-86 cm chest measurement meant for the employee belonging to backward class. The writ petitioner questioned the legality of the said order in the writ petition, which was considered by the learned Single Judge and it was held that the writ petitioner being Scheduled Caste by birth and also at the time of joining the service and as such, the benefit with regard to the physical requirement cannot be altered on the basis that he had converted to Christianity subsequently and the writ petitioner was entitled to all benefits on that basis. 4. 4. Mr.P.S.Shivashanmugasundaram, the learned Special Government Pleader would submit that after conversion to Christianity, the writ petitioner was removed from the category of scheduled caste and was included in the backward class community and as such, he did not possess the requisite physical qualification, as aforestated. Thus, the writ petitioner was rightly denied regularisation and further promotion on the basis of his appointment against the scheduled caste category. 5. We have examined the case very carefully and perused the documents and pleadings. The documents available before us do not indicate that there is any prohibition for conversion from one religion to another religion. It is also not brought to the notice that under any provisions of law or the executive instructions or government circulars, if an employee converts to other religion, he has to attain requisite physical qualification on the basis of converted community in the course of his service. 6. The physical requirement of a person is to effectively perform the duties assigned to him on the basis of the nature of job. The writ petitioner was appointed on 15.3.1966 on having found that he had requisite height and chest required for scheduled caste candidate. In that capacity, he was allowed to continue and there is no grievance that his functioning, at any point of time, was deficient and as such, he was not entitled to be considered for further promotion on the basis of his working seniority. After a period of working for about 16 years, the writ petitioner could not have been denied the benefit of working experience by way of seniority for further promotion. 7. Needless to state that the writ petitioner was temporarily promoted to the post of Chief Head Warder and there also, no complaint about his working on the said post was noticed. Thus, subsequently, on discovery that he had converted to some other religion, he cannot be denied the benefit, to which he is entitled to. 8. As a sequel, we do not find any irregularity or irrationality in the view taken by the learned Single Judge while allowing the writ petition. We confirm the same and consequently, dismiss the writ appeal. No costs. Consequently connected miscellaneous petition is closed.
