Motor racing's governing body FIA has officially stated Sebastian Vettel did not violate Formula One rules in an overtaking manoeuvre at the Brazilian Grand Prix on Monday, meaning the German's third straight world title stands.
The FIA says they have told the Ferrari team in a letter that Red Bull's Vettel acted within the rules when he overtook Jean-Eric Vergne of Toro Rosso.
Ferrari had sought clarification after video evidence seemed to indicate that Vettel had overtaken Vergne in a yellow-flag danger area where passing is prohibited.
But race director Charlie Whiting says a marshall waving a green flag had allowed Vettel to pass Vergne.
