Sarthak Sidhant>>>, a Class 12 student, alleged relaxed tender criteria favored Coempt Edutech>>> for the OSM contract. The India — National Students Union of India>>> (NSUI) has filed a Public Interest Litigation in the India — Delhi High Court>>>, seeking an independent inquiry and remedial measures for affected students.
