Key to the decision was that evidence considered as "new" was only that which was not available to Ferrari by the end of scrutineering after the race.
Hamilton won last year's French Grand Prix from pole position and has triumphed at five of seven races this year.
Chandhok competed in 11 F1 grands prix between 2010 and 2011 and it is hard to square his post-race opinions with the "overwhelming" evidence Ferrari claim to have complied, and their two-week long pursuit of overturning Vettel's penalty has been left looking futile and somewhat absurd.
"We've just been chipping away at improving the set-up of the vehicle", added the Briton, who is 29 points clear of Bottas after seven races - all won by the pair.
Speaking after his 79th career victory, he told reporters they should consider who should be blamed before drawing any conclusions.
"We have nothing to do with the money and all that kind of stuff. To get the best out of people, you have got to deliver the right environment for them - that is so important".
As a keen follower of other racing series, including Indycars in the United States, Hamilton has often said Formula One needs to change its technical rule-book to encourage much closer racing.
"We believe this evidence is quite overwhelming when it comes to establishing that Sebastian did not breach any regulations", he said.

And he made one thing clear: Don't compare him to National Basketball Association players who came before him. Memphis is set to draft point guard Ja Morant with the second overall pick on Thursday evening.
He said he welcomed the fact that the sport's ruling bodies were open to hearing the views of the drivers.
"I was not expecting the medium tire to go as far as it did but I was able to continue", Hamilton said. He is a fan of the history of the sport, and like anybody, when you enjoy what you are doing, you do it that much better.
"It's because the way Bernie [Ecclestone, ex-F1 boss] had it set up, the decisions they were making back then".
He would not be drawn to say he had confidence that the initiative would result in the necessary dramatic changes to transform the racing and eliminate boring processions. "My job's to come here and do the best I can as a driver". "We bring some information that maybe the stewards didn't have at the time".
He added that he remained optimistic. "And maybe we just need to have a very long straight rather than a chicane in between to allow for more slipstreaming".
"This is a constant cycle of Formula One, for years and years and years even before I got here, it's because of the way Bernie [Ecclestone] had it set up and the decisions that were made then are still the same".
"But I am encouraged that Ross (Brawn, F1 director) and his team are working, for the first time, on a real aero package that hopefully will have an impact".
