In Ran Vijay Singh v. State of Uttar Pradesh, decided on December 11, 2017, the Supreme Court set out how courts should handle disputes over exam results. It allowed re-evaluation only where the rules permit it or where a material error is clearly shown.
Otherwise, “The Court should not at all re-evaluate or scrutinize the answer sheets of a candidate.” Academic matters “are best left to academics.” In case of doubt, “the benefit should go to the examination authority rather than to the candidate.”
