In a setback to Sikkim High Court Chief Justice P D Dinakaran, the Supreme Court today refused to quash some of the charges framed against him by a Rajya Sabha-appointed panel looking into allegations of corrupt practices and misconduct against him. A Bench headed by Justice G S Singhvi, however, allowed Dinakaran's plea seeking removal of senior advocate P P Rao from the inquiry panel. The Bench asked Rajya Sabha Chairman and Vice President Hamid Ansari to reconstitute the panel by replacing Rao with another distinguished jurist. The court, however, made it clear that Justice Dinakaran will be facing the same charges which were framed by the three-member Committee comprising Supreme Court Judge Aftab Alam, Karnataka High Court Chief Justice J S Khehar and senior advocate P P Rao.
