The order was passed by a Division Bench, comprising Justices Rajesh Kumar and Manoj Misra, on a writ petition alleging that there were mistakes in the General Knowledge paper of the Prelims examinations held earlier this year.
The petition was filed by Manoj Kumar Yadav and others.
They have claimed that a number of candidates were declared successful despite giving wrong answers to the multiple choice questions, while many deserving ones had failed to make it to the Mains because of the discrepancy.
Fixing October 10 as the next date of hearing, the court restrained the Uttar Pradesh Public Service Commission from holding the Mains exam for PCS(J) from September 28.
The court also ordered setting up of a 4-member experts committee to look into the allegations. The committee was also directed to submit its report before the court by the next date of hearing.
