The Supreme Court today dismissed petitions seeking a review of its judgment refusing a CBI investigation into the Rafale fighter jet deal with French firm Dassault Aviation and giving the government a clean chit. On May 10, the Supreme Court had reserved the decision on the petitions, including one filed by former union ministers Yashwant Sinha, Arun Shourie and activist lawyer Prashant Bhushan, seeking a re-examination of its findings that there was no occasion to doubt the decision-making process in the procurement of 36 Rafale fighter jets.
