New Delhi, Sept. 10 -- The Delhi High Court on Tuesday dismissed a plea by Nitish Katara murder convict Vikas Yadav seeking extension of his interim bail, holding that it lacked the power to grant such relief after conviction. The court said only the Supreme Court could exercise "extraordinary powers" under Article 142 of the Constitution in such matters. The refusal means Yadav, who has been out on interim bail since April 24, must surrender as his bail expired on Tuesday. Justice Ravinder Dudeja, while passing the order, said: "In the present case, the petitioner already stands convicted, his appeal has been dismissed by this Court, and his SLP before the Supreme Court also stands dismissed...No provision to grant or extend interim bail." The bench noted that the SC had earlier granted Yadav interim bail by invoking Article 142, but the high court had no such jurisdiction. "The application for extension of interim bail is therefore not maintainable and is dismissed," it said. Yadav had approached the high court a day after the Supreme Court itself refused to extend his bail. In his plea, he argued that he needed more time with his wife and to arrange the Rs.54 lakh fine imposed by the high court by selling family properties, a process he termed "legally intricate." Opposing the plea, Nitish Katara's mother Nilam, represented by advocate Vrinda Bhandari, called the marriage a "mere formality for judicial records."...
