This was reported on the FIA website.
The race was won by the Dutch Red Bull driver Max Verstappen and thanks to this became the champion of the season.
British Mercedes driver Lewis Hamilton finished second.
The first protest by Mercedes is related to Verstappen overtaking Hamilton behind the safety car, and the second indicates a possible violation of the restart procedure after the pace car mode.
The British team is demanding a review of the final classification, because of which Verstappen may lose the title.
Before the final race in Abu Dhabi, the pilots had the same number of points.
Thus, the fight for the first place was decided only at the final stage of the season.
Earlier, Hamilton spoke about the defeat at Verstappen in the decisive race of the season.
