New Delhi, Oct. 9 -- The Supreme Court on Thursday deferred by a day the Punjab government's challenge to a high court order directing the Central Bureau of Investigation (CBI) to register a criminal case into alleged corruption linked to chief minister Bhagwant Mann's office, refusing to pass any interim order against the probe without first allowing both judges on the bench to examine the matter. A bench of justices Dipankar Datta and Sheel Nagu agreed to hear the matter on Friday after senior counsel Vikas Singh, appearing for the Punjab government, pointed out the urgency and sought an interim direction that CBI and Enforcement Directorate (ED) "may not precipitate the matter". Justice Datta, however, made it clear that such an order could not be passed without justice Nagu having an opportunity to peruse the petition. "How can we pass this order when the file did not reach the other judge," justice Datta told Singh. The bench was told that the case file had not reached justice Nagu, who was sitting as the puisne judge on the bench, in time. Singh agreed to the deferment to enable justice Nagu to go through the state government's challenge but pressed for the matter to be taken up at the earliest. Justice Datta, who was heading the bench, then agreed to list the matter on Friday. Singh also raised a possible issue concerning justice Nagu's participation in the case, pointing out that the judge, while serving as chief justice of the Punjab and Haryana high court, had dealt with some matters concerning the petitioners in the Supreme Court case -- Punjab director general of police Gaurav Yadav and the chief director. Singh clarified that those proceedings were unrelated to the present case. Justice Nagu said he would need to examine the file before taking a call on whether he could hear the matter. The case has unfolded against a charged political backdrop in Punjab, with assembly elections due early next year and the Mann government alleging that the CBI and ED action is politically motivated targeting by the BJP. The development came a day after the CBI's first steps under the high court's October 5 order, including searches at eight locations across Punjab and the summoning of Punjab chief minister Bhagwant Mann's officer on special duty (OSD), Rajbir Singh Ghuman, and five others in the corruption case. Ghuman and the five co-accused did not appear before CBI at its Chandigarh office on Wednesday. While the chief minister's office said Ghuman had not been formally served the summons, sources indicated that the accused had also held off on appearing while awaiting the Supreme Court's consideration of the Punjab government's plea. CBI registered a 251-page FIR around midnight on October 5, naming Ghuman, alleged middleman Nitin Gohal, his brother Jitin Gohal alias Raja, Romi Raja Mahajan, Bir Devinder and RS Nagra. The agency has alleged that the accused operated an organised network to manipulate IAS and IPS postings, departmental proceedings, policy formulation, administrative approvals, tenders, licensing, arms licences and land-use conversions in return for bribes. The agency also alleged that unreleased government notifications and internal draft policies were leaked to private beneficiaries. The case originated in three communications sent by ED to Punjab DGP Gaurav Yadav between July 24 and August 12, raising allegations of corruption involving Ghuman and others. ED had alleged that Gohal acted as an intermediary between people seeking favours from the state government and Ghuman, including for transfers and postings of officials, government approvals and arms licences....
