The Supreme Court on Thursday refused to defer the Uttar Pradesh Public Service Commission mains examination to be held on June 18, PTI reported. It also set aside the Allahabad High Court’s order for a revaluation of answer sheets of the preliminary test.

Several students have petitioned the top court alleging that answers to many questions asked in the commission’s preliminary examination were incorrect.

A bench of Justice UU Lalit and Justice Deepak Gupta dismissed a batch of petitions by some students who said the exams should be stayed as the commission had not complied with the High Court’s April 2 order. The court was hearing the commission’s plea against the verdict.

The court said that the candidates must demonstrate that the answer keys were wrong before it could rule in their favour. It added that the judges could not be expected to be experts in every field. “When there are conflicting views, then the court must bow down to the opinion of the experts,” the bench said. “Judges are not and cannot be experts in all fields and, therefore, they must exercise great restraint and should not overstep their jurisdiction to upset the opinion of the experts.”

Referring to a 1983 verdict, the Supreme Court said it had recommended a system of moderation to avoid ambiguity in exam questions. In this case, the bench said, the Uttar Pradesh Public Service Commission had got the answer keys moderated by two expert committees and invited objections, which were then examined by a 26-member panel.
