Red Bull boss Christian Horner is surprised Ferrari has requested the stewards look into the penalty handed to Sebastian Vettel in Mexico.
Ferrari has re-opened the controversy from the Mexican Grand Prix, which saw Vettel handed a ten-second penalty (dropping him from third to fifth) for moving under braking while defending position. He was penalised under what has become known as the 'Max Verstappen rule', after an amendment made to the rules in Austin to clamp down on Verstappen's tactic of moving into the path of another car.
Though it seemed like the matter was closed coming to Interlagos, on Thursday Ferrari released a statement asking for the stewards to revisit the case after "a number of new elements" came to light, though the team has not revealed what those are. Horner thinks Ferrari risks setting a dangerous precedent for future cases.
Speaking to Sky Sports, Horner said: "I'm a bit surprised that it's come about. I don't know what the new evidence is but it must be fairly compelling. Ferrari must think it's fairly strong.
"Maybe there's some new evidence you never know that might come about Max's penalty. Maybe we'll get him back on the podium or maybe we'll have another look on Monaco or some of the other races
"It's fairly strange to be going back like this. You shut the book on it, you have to accept what the referee's decisions are and move on."
Horner thinks the sport has too many rules preventing the drivers from properly racing.
"It's almost that you have a rule that drivers are not allowed to race because we're regulating so much. And so much fuss has been made over Max's moves that they may come up and they're putting more regulations.
"And obvisouly they've applied these regulations and penalties have been given. I think the rules are too confusing for us competitors to know what is legal and what is not, let alone how on earth you convey that to the fans."
The penalty demoted Vettel behind both Red Bulls, with Daniel Ricciardo inheriting third and Verstappen moving into fourth. Verstappen himself had lost his podium position for a ten-second time penalty for not giving up third position to Vettel after going off track and gaining an advantage.
