Supreme Court Chief Justice Jagdish Singh Khehar on Wednesday issued a contempt notice to Calcutta High Court judge Justice C.S. Karnan for writing letters casting aspersions on several judges.

Asking Justice Karnan to appear in person on February 13, a constitution bench comprising Khehar and six other judges directed that Justice Karnan would not discharge any judicial and administrative functions during the pendency of the proceedings.

It also directed Karnan to hand over all files relating to his judicial and administrative functions to the Registrar General of the High Court.
