Red Bull on Thursday officially lodged their appeal against Daniel Ricciardo's disqualification from second place in Sunday's Australian Grand Prix, motorsport's governing body the FIA confirmed.
The Formula One champions' protest arrived at FIA's Paris headquarters shortly before the 96 hour deadline of 1300GMT.
Red Bull had made it plain ever since Ricciardo lost his his runner-up spot to Nico Rosberg in the Melbourne stewards room on a technical infringement that they would challenge the ruling.
Ricciardo's fate now lies in the hands of the FIA's appeals board which will sit in the next few weeks.
Red Bull boss Christian Horner has absolved Ricciardo of any blame in the bungle.
After a marathon hearing, stewards in Melbourne said the 24-year-old's car was not in compliance with F1 regulations after he exceeded the maximum fuel flow, or rate of fuel consumption, of 100kg/h.
It made Ricciardo the first casualty of new limits on fuel load and fuel flow introduced this year.
"It is no fault of Daniel. I don't believe it is the fault of the team," Horner told Australian media.
