Sikkim High Court Chief Justice P D Dinakaran has resigned from his post on Friday. He is facing impeachment allegedly on charges of corruption and judicial misconduct. In a two-page resignation letter sent to President Mrs. Pratibha Devi Singh Patil, he said he had been denied fair opportunity to defend himself and his reputation by the Judges Inquiry Committee. Justice Dinakaran said he had a suspicion that his misfortune was because of the circumstances of his birth in the socially oppressed and underprivileged section of the society. He is the third Judge of the higher judiciary to face impeachment proceedings. The impeachment motion against Justice V Ramaswamy of the Supreme Court was defeated in the Lok Sabha in mid-nineties while the inquiry report of three- member committee appointed by the Rajya Sabha Chairman against Justice Soumitra Sen of the Calcutta High Court is still pending.
