Paris: Red Bull on Tuesday lost their appeal over Daniel Ricciardo`s Australian Grand Prix disqualification.
The world champions had sought to overturn the stripping of Ricciardo`s second place in Melbourne for breaching fuel flow regulations.
The FIA`s International Court of Appeal issued a ruling after a six-hour hearing Monday when other teams had called for the punishmen to be toughened.
Red Bull`s rookie Australian driver is left in 10th place in the championship with 12 points, 49 behind Mercedes` pacesetter Nico Rosberg ahead of Sunday`s Chinese Grand Prix.
Red Bull are fourth in the constructors` standings on 35 points with Mercedes leading on 111.
