A Supreme Court bench headed by Chief Justice of India (CJI) N V Ramana on Monday expressed unhappiness over repeated disruptions during virtual hearings due to the use of mobile phones by several advocates, and said it may have to ban participation through mobiles. A bench comprising the CJI and justices A S Bopanna and Hima Kohli was unhappy over the fact that it had to adjourn the hearings in as many as 10 cases listed on Monday due to disruptions in either audio or visual or both from advocates' end during the proceedings.
