duties. There was intermixing of the duties performed by the two categories of the Health Inspector Grade IA and IB. Both the posts had lost their original identity since 27-6-1997, and formed one homogenous cadre. Further, having relaxed the qualifications on the basis of their length of service and experience, they were on a par with the Health Inspector Grade IA. Thereafter, the State was not justified in denying to the erstwhile Health Inspector Grade IB, the same treatment as was given to Health Inspector Grade IA. Therefore, the respondents could not have been denied the benefit of service on the post of Health Inspector Grade I from the date of the initial integration. It would be appropriate to notice the ratio of law laid down in SubInspector Rooplal [Sub-Inspector Rooplal v. Lt. Governor, (2000) 1 SCC 644 : 2000 SCC (L&S) 213] , wherein it was inter alia held that the previous service of the transferred officials who are absorbed in an equivalent cadre in the transferred post is permitted to be counted for the purpose of determination of seniority. It would be appropriate to notice here that Leprosy Inspectors redesignated as Health Inspector Grade IB have not been granted the benefit of seniority in their cadre from the date of their initial appointment. They have been deprived of their service on the post of Leprosy Inspector up to 27-6-1997 when they were integrated and redesignated as Health Inspector Grade IB. However, upon merger w.e.f. 27-6-1997, there was no distinction in the services rendered by Health Inspector Grade IA and Health Inspector Grade IB. Therefore, in our opinion, the provision in GOMs No. 382 of 2007 not to grant the Health Inspectors Grade IB/erstwhile Leprosy Inspectors the benefit of the service from 1997 for determination of their seniority for promotion to the post of Block Health Supervisor was completely unjustified. 61. Thus, the High Court, in our opinion, was completely justified in quashing Clauses 6(iv) and (v) of GOMs No. 382 of 2007. The High Court has correctly held that the redesignated Health Inspector Grade I ought to have been given the same scale of pay as Health Inspector Grade IA
