Paragraphs : 13. The judgment in Anushka (supra) analyzed the position with respect to various provisions of the Foreigners Act, 1946 and the Citizenship Act, 1955, especially Sections 7A to 7D and the notifications prior to the one in question, i.e., dated 11.04.2005, 05.01.2007 and 05.01.2009 which also were issued under Section 7B of the 1955 Act. Each of the notifications had declared that OCI Card holder are to be treated and granted status at par with Non Resident Indians (NRIs) and Indian Nationals, including appearing in All India Pre-medical Test and all such other tests to render them eligible for admission pursuant to provisions of the relevant Act.
The notification dated 04.03.2021 pertinently states as follows :
14. The facts in this case are not disputed; undoubtedly the petitioner was treated as a foreign national and allowed to appear in the NEET mains- as OCI cardholder; she even secured a fairly high rank. She was allowed to participate in the mock rounds of allocations which led to an indication that she would be offered PG in Paediatrics in AIIMS and just before the first round of counselling she was informed that her status would no longer be as a foreign national and that she would be treated as an Indian national.
15. A plain reading of the notification undoubtedly leads one to conclude that it withdraws the eligibility or privileges which had been hitherto conferred upon OCI Card holders regarding their parity with Indian nationals for appearing in All India examinations such as NEET. This meant that after the date of issuance of that notification, i.e. 04.03.2021, such OCI card holders could not claim the privilege of eligibility for admission in any competitive entrance examination “any seat reserved exclusively for Indian citizens” was an abrupt notifications all these notifications were somewhat softened by of the retroactive application facially was that all OCI Card holders who had planned their academic careers based upon pre-existing notifications dated 11.04.2005, 05.01.2007 and 05.01.2009 were held to be eligible to continue with that privilege in terms of the judgment in Anushka (supra). The relevant portions of the judgment in Anushka (supra) are extracted below :
16. It is evident that the ruling held that notification (dated 04.03.2021) operated arbitrarily because firstly it indicated non-application of mind in not saving accrued rights. The application of proviso to Clause 4 (ii) of the notification of 04.03.2021 was held to have no nexus with the objects sought to be achieved. The court also held that those who are born prior to 2005 and residing in India had received their education in India and had pursued by having some advantages and disadvantages like other children who are citizens of India, and could not be denied their right to participate in NEET examinations or such similar examinations. It was also held that no additional advantage was granted to such class of people merely because they were born abroad and importantly, court took note of the amendment which introduced concession to OCI Card holders. Therefore, the Court concluded that when the right conferred was withdrawn and altered, in the process leading to such change, should demonstrate application of mind, nexus to the object of such withdrawal or modification and any such decision had to be free of arbitrariness. In the light of this conclusion, the court held that the notification saved from the vice of non-application of mind and was in fact retroactive. It was in these circumstances that the Court held that only those persons who obtained OCI Cards after 04.03.2021 were rendered ineligible in terms of the notification.
