The four judicial officers were appointed as judges at the Delhi High Court by the President after the Collegium of the Supreme Court recommended their names for elevation earlier this month.

Justices Jyoti Singh, Prateek Jalan, Anup Jairam Bhambhani, Sanjeev Narula were sworn-in as Delhi High Court judges in October
