The Red Bull Formula One team's appeal against Daniel Ricciardo's disqualification from the Australian Grand Prix has been rejected by the International Court of Appeal.
The young young Australian finished second in his home race last month, on his debut for the world champions, but was disqualified hours later when stewards ruled his car had breached new fuel flow regulations.
No further sanction against Red Bull was announced.
The FIA added that details of the decision would be published by the end of the week.
Red Bull issued a statement expressing their disappointment with the decision, insisting that they adhered to the technical regulations throughout the Australian Grand Prix.
The ruling means that Ricciardo remains 10th in the drivers' standings on 12 points, having lost 18 points as result of the disqualification, and Red Bull stay fourth in the team standings.
The case was seen as a critical test of the regulations accompanying the V6 turbo engines and energy recovery systems, with Red Bull arguing the sensors cannot be trusted.
Red Bull, instead, used their own method of measurement, which was in breach of an FIA technical directive.
