JUDGMENT Arun Palli, J. This is an intra Court appeal, under Clause X of the Letters Patent, against an order and judgment dated 19.07.2022, rendered by the learned Single Judge, vide which the writ petition preferred by the appellants has since been dismissed. 2. Learned counsel for the appellants has virtually reiterated the submissions that were advanced before the learned Single Judge, that pursuant to an advertisement No.1/2021, dated 21.02.2021, 253 posts of Tubewell Operator were advertised by the Punjab Water Resources Management and Development Corporation. For, a candidate to be eligible he was required to possess: Matric with Punjabi + 2 year ITI certificate in Electrician trade from Govt./recognized ITI. Whereas, the appellants were holder of Trade Certificate in Pump Operator-cum- Mechanic (1 year) Course. Thus, they challenged the advertisement, for, the eligibility qualification prescribed by the authorities were contrary to the nature of the post of Tubewell Operator, which was/is mechanical in nature. Further, in reference to the order dated 22.09.2011, passed by a Single Bench of this Court in CWP No.6356 of 2011 (P3), he submits that even earlier the respondents had amended an advertisement that required ITI Certificate in Electrical Trade to add the qualifications possessed by the petitioners therein. An order dated 28.09.2012, passed in LPA No.2297 of 2011, was also referred to, to stress that even during the previous recruitment, respondents had accepted diploma in Pump Operator-cum-Mechanic, and, therefore, the condition that a candidate must possess two years ITI Certificate in Electrician Trade is wholly erroneous and unsustainable. Further, even the letter dated 09.03.2020 (P4), issued by the Executive Engineer, Punjab Water Supply and Sewerage Board, Sangrur, showed that candidates with Pump Operator and Mechanic Diploma were eligible to operate the water work. But, the learned Single Judge apparently failed to examine/analyze the claim of the appellants, in the right perspective. 3. We have heard learned counsel for the appellants and perused the records. 4. Concededly, the posts that were advertised and sought to be filled were of a Tubewell Operator. As indicated earlier, for, a candidate to compete for selection he/she was required to possess two years ITI Certificate in Electrician trade from Govt./recognized ITI. It is not in dispute that appellants did not possess the prescribed qualification, for, they possess a trade certificate in Pump Operator-cum-Mechanical (1 year) course. As indicated earlier, for, a candidate to compete for selection he/she was required to possess two years ITI Certificate in Electrician trade from Govt./recognized ITI. It is not in dispute that appellants did not possess the prescribed qualification, for, they possess a trade certificate in Pump Operator-cum-Mechanical (1 year) course. The order dated 22.09.2011 (ibid) upon which reliance is sought to be placed would not advance the cause of the appellants either. For, in those proceedings the posts in question were of Pump Operators and not Tubewell Operators. Similarly, the reliance placed upon an order dated 28.09.2012 (ibid), to contend that even previously, while making recruitment, the respondents had accepted the Diploma in Pump Operator- cum-Mechanic is equally mis-conceived as even in the said case the subject post was of a Pump Operator. Further, the letter dated 09.03.2020 (ibid) would also not advance the claim of the appellants, for all what it shows is that Superintending Engineer of the Board was requested to conduct a Course of Pump Operator-cum-Mechanical Trade at Principal Govt. Udyog Sikhlai Organization, Sunam (Uddam Singh Wala). And, subject of the said letter read as thus: "Subject: For making Pump Operator-cum-Mechanic as a technical qualification for the post of Pump Operator." Therefore, it has no concern with the claim of the appellants. 5. We consider it expedient to even refer to the specific stand, set out by the respondents, in the return, regarding: minimum qualification prescribed for the post of Tubewell Operator in Punjab Water Resources Management & Development Corporation Employees Service Bye-Laws, as amended from time to time, is Matric with Punjabi + 2 year ITI certificate in Electrician trade from Govt./recognized ITI. The respondents, in countenance of the qualification prescribed in the Bye- Laws and the advertisement, have also given a comparative chart of the competency based curriculum for the Electrical Trade ITI vis-a-vis Pump Operator-cum-Mechanic Trade reads thus:- Electrical Trade I.T.I. Pump Operator-cum-Mechanic Trade During the two years duration of Electrician Trade a candidate is trained on professional skills & knowledge, Engineering Drawing, Workshop Calculation & Science and Employability skill related to job role. In addition to this a candidate is entrusted to undertake project work and extracurricular activities to build up confidence.

Ex facie, the Electrical Trade ITI is a two years Course whereas Pump Operator-cum-Mechanic Trade is one year course and even the study material as also the practical knowledge of both the courses was different. Needless to assert that prescription of a requisite qualification for appointment to a particular post is the domain of the employer/recruitment agency, and thus, cannot be interfered with unless the prescribed qualifications are apparently arbitrary and irrational. Further, as observed by the learned Single Judge selection in terms of the advertisement dated 21.02.2021, have since been carried out. 7. In the wake of the position, as sketched out above, we are dissuaded to interfere with the impugned order and judgment rendered by the learned Single Judge. The appeal being bereft of merit is accordingly dismissed.
