"13. Further, as far as Central Government institutions are concerned, no distinction is made between Scheduled Caste candidates who have the origin in a particular State or Union Territory and Scheduled Caste candidates who have migrated. This clarification is obtained in the Government of India, Department of Telecom Letter No.1-13/92-SCT dated 18/31.8.1992. As per the clarification obtained from the Ministry of Welfare and Ministry of Home Affairs, Department of Personnel and Training, there is no distinction between origin and migration cases as far as Central Government institutions are concerned. They are applicable only to State Government services and State Government educational institutions. Applying this criteria and in view of the fact that the conditions in Clause 3.5.1 of the Prospectus were met, respondents 4 to 12 have been admitted. The percentage of reservation for Scheduled Caste candidates in the respondent Institution is 15% and out of the 75 seats, 20 seats are reserved on residential basis and for the remaining 55, if 15% reservation is applied, it comes to 8.25 and therefore, 8 seats are given under the Open Scheduled Caste category. As regards the 20 seats, 15% reservation will actually come to three seats. On the other hand, five seats are given for Pondicherry Scheduled Castes. Therefore, the quota for Scheduled Castes has not been diminished. Out of that quota, as a concession, the Pondicherry Scheduled Caste candidates, as defined in the Prospectus, have been given five seats. The petitioner has participated in the examination quite aware of the reservation for Pondicherry Scheduled Castes. Having participated in the examinations, he now finds himself out of the running since other students who also applied under the Pondicherry Scheduled Caste category have acquired more marks than him; so, he has laid the challenge. There is no violation of the Constitutional requirement of reservation. "
