The Supreme Court today dismissed the petitions filed by former Union Minister Natwar Singh and his son seeking supply of documents of Volcker and R S Pathak Committees which had probed their alleged role in Iraq's oil-for-food scam. A bench comprising Justices B Sudarshan Reddy and S S Nijjar said the petitions seeking documents are delaying tactics on the part of the former Congress leader and his son Jagat Singh. The bench said, the petitions are an attempt to obstruct the proceedings in the case before the Enforcement Directorate. The bench ordered for the expeditious disposal of the proceedings before the ED and said that no adjournments should be given on unreasonable grounds.
