19. At this juncture, we may notice that in any selection, for the purposes of providing vertical reservation, separate merit lists are prepared and these separate merit lists are; (i) merit list for Scheduled Castes category candidates, (ii) merit list for Scheduled Tribes category candidates, (iii) merit list for Other Backward Classes category candidates, and (iv) merit list for open category candidates. Thus, in a situation where vertical reservation to the SC/ST/OBC candidates is to be applied simultaneous with the application of horizontal reservation in terms of the Act, 1993, the Selection Body/Appointing Authority is to first prepare separate merit lists of Scheduled Castes, Scheduled Tribes, Other Backward Classes and Unreserved category candidates. Simultaneously, the Selection Body/Appointing Authority is also required to prepare a combined merit list comprising of all the selected candidates and in case in this combined merit list any candidate claiming reservation under the Act, 1993 gets included, he is to be adjusted against the separate merit lists already prepared for SC/ST/OBC/Open categories. In such a process, for adjusting the special category candidates in the separate select lists, the last person(s) i.e. the person(s) placed at the bottom in the separate merit lists prepared for different category candidates is/are to be removed/deleted/ousted depending upon the number of special category candidates selected in terms of the Act, 1993.
