New Delhi, Feb 13 (IANS): The Supreme Court on Monday deferred for three weeks a hearing on contempt proceedings against Calcutta High Court judge Justice C.S. Karnan as he did not appear before the court as directed.

A seven-judge constitution bench directed the next hearing on March 10, noting that "we are not aware of the reasons for non-appearance" of Karnan, said: "We refrain from proceeding in the matter as of now."

The order came even as Attorney General Mukul Rohatgi told the court that under the Supreme Court Rules it was mandatory for Karnan to appear.

Rohatgi who is assisting the court in the matter urged the bench to frame a charge and asked Karnan to respond to them on the next date of hearing.

"Frame a charge today (Monday). Record that you (Justice Karnan) have not appeared and showcause him on the charge," Rohatgi told the bench.

As Rohatgi tried to focus on Karnan's non-appearance pointing out that the tone of his communication to the Registrar General of the apex court was no different from his earlier ones, the bench said :"The letter doesn't say he can't appear. He says that he has not been granted time."

The Supreme Court had issued the contempt notice on February 8.
