There is no occasion to doubt the decision-making process in the procurement of 36 Rafale jets from France, the Supreme Court said on Friday and dismissed all the petitions seeking an investigation into alleged irregularities in the Rs 58,000 crore deal.

There was no substantial evidence of commercial favouritism to any private entity, the bench headed by Chief Justice Ranjan Gogoi said on the issue of an offset partner in its ruling on a batch of petitions.
