NEW DELHI: As it has become an annual affair for court to get flooded with petitions for admission to medical colleges after declaration of NEET results, Supreme Court Monday asked National Medical Commission and Centre to frame tamper-free rules to prevent unnecessary litigation, which create uncertainty for candidates.A bench of Justices P S Narasimha and Alok Aradhe proposed that a mechanism be put in place to review the rules every year to improve upon them. Emphasising that the country is mature enough to build sound institutions, the court said that more rigour needs to be infused into the selection process.The court was hearing a batch of petitions challenging reduction in cut-off marks for PG admissions.It had earlier issued notices to Centre and NMC in this connection.With over 18,000 postgraduate medical seats across the country remaining vacant, National Board of Examinations in Medical Sciences (NBEMS) had revised the qualifying percentiles for NEET-PG 2025 admissions, reducing it to zero from 40 percentile for reserved categories – which will allow even those scoring as low as minus 40 out of 800 to take part in third round of counselling for PG medical seats.According to the notice published by NBEMS, the NEET PG cutoff for general category has been reduced to seven percentile from 50.
