After the controversial Formula 1 final in Abu Dhabi with the new world champion Max Verstappen, the stewards rejected both protests by Mercedes.
The race stewards considered both objections to be permissible hours after the end of the race.
However, there was no subsequent penalty for Verstappen or Red Bull.
The Dutchman continued to be rated as a race winner and also a world champion.
However, further action by Mercedes against the stewards' decision cannot be ruled out.
The racing team reserved the right to appeal.
After the Grand Prix victory in Verstappen, the Silver Arrows complained about two alleged breaches of the rules in the last race of the year on Sunday.
Both incidents related to the last safety car phase shortly before the end, when Verstappen was finally able to overtake Hamilton and become world champion for the first time.
The first protest related to the fact that Verstappen should have illegally overtaken Hamilton during the safety car phase.
The stewards also assessed the objection as admissible and agreed that the Dutchman is said to have been slightly ahead of the British for "a very short period of time".
At the end of the safety car phase, however, this no longer applied.
In a second protest, Mercedes complained about the allegedly incorrect procedure during the last safety car phase. In essence, it was about the fact that the safety car should have stayed outside longer - then the race behind Bernd Mayländer's car would have ended and Hamilton would have become world champion. Because overtaking is then no longer allowed. The stewards also rejected this protest.
The reason given by the four race stewards Garry Connelly, Felix Holter, Derek Warwick, and Mohamed Al Hashmi, with which they threw off the protest, showed how difficult the whole thing is. Remarkably, they also made use of Red Bull's arguments that the team was the third party affected at the hearing. It was about formulations and interpretations of the terms “any” and “all” in the English-language regulations, because only five instead of eight cars were allowed to turn back before the end of the safety car phase.
The point was that article 48.13 could overwrite article 48.12 and that article 15.3 would also give the race director "overriding authority" when using the safety car, because it did not come back in at the end of the following lap, as is usually the case was.
Then the race and the season would have come to an end behind the car with Bernd Mayländer at the wheel.
Race director Michael Masi, who had been criticized a week earlier because of the bazaar-like action that was publicly broadcast via radio, also argued that there had been an agreement with the teams for a long time not to end races behind the safety car.
