The MCA tender results may get cancelled because neither of the entries (Rafale and EF) can meet the cost requirements. This would mean that they would have to either reconsider some of the dropped entries, or decrease the number of airplanes.
I'm not so sure that this is a legitimate view
All submissions are subjected to a prelim review to ensure that they meet the Govts basis of compliance.
If cost was an absolute constraint then they would have been eliminated at prelim review
Cost is usually considered last, and even if they are high (and I've seen submissions where one vendor was 2.5 times higher than another competitor) then they will still be assessed on technical merit first. Govt always takes the view that they can negotiate a price down as while they are still in negotiation they can default to the next attractive bid
i'd say that the articles view is spurious.
