An Australian court has upheld the decision to allow Giedo van der Garde to race for the Sauber Formula One team in Melbourne this weekend.
The Dutch driver, signed as a test driver for the 2014 season, claimed he had a contract to race for the Swiss team this season.
A court had sided with van der Garde on Monday, but Sauber had decided to appeal the decision.
However, on Thursday, the appeal verdict ruled in favour of van der Garde, meaning the Dutchman is entitled to race this weekend.
"In our view for the reasons given by the trial judge, the judge did not err in making the orders from which the applicants seeks leave to appeal," the appeal judge said.
"The application for leave to appeal is allowed but the appeal is dismissed because we see no error in the reasons of the trial judge."
It is unclear what will happen now, as Sauber has Felipe Nasr and Marcus Ericsson under contract, and van der Garde has not driven the 2015 car yet.
