in Spanish in the CSPILAS, whether in the prospectus released by the JNU in that regard or elsewhere, which proscribes adjustment of the petitioner against a vacant seat in the Foreign National category. He submits that the principles which apply to adjustment of candidates falling under one reserved category against a vacancy in another category, in service law, would not apply mutatis mutandis to education law. This proposition, he submits, has been clearly laid down in M. Shravana Kumar and Hari Singh Nalwa Trust , amongst others. The guiding principle when dealing with vacancies for admission into educational institutions, he submits, is that vacancies should not be allowed to remain unfilled, in the interest of ensuring that the reach of education is maximised. Where a candidate, who is willing to undergo the Ph.D. programme in Spanish is available, albeit in another category, he should not be denied admission merely because the vacancy is not in the category to which he belongs. It is this prevailing philosophy, he submits, which also guides Clause 6.3 of the admission policy of the JNU.
