Haas has failed in its bid to overturn Romain Grosjean’s disqualification from the Italian Grand Prix.

The FIA International Court of Appeal has upheld the decision by the stewards of the race to disqualify Grosjean from sixth position because his car’s floor did not comply with the technical regulations.

In a statement the court confirmed its decision “to confirm the exclusion of Haas F1 Team’s car number eight from the 2018 Italian Grand Prix held in Monza counting towards the 2018 FIA Formula One World Championship.”

“To date, only the operative part of the decision has been notified to the parties,” it added. “The full decision including grounds will be notified later on.”

Haas team principal Guenther Steiner did said: “Obviously we are disappointed not to have won our appeal.

“We simply move forward and look to the final two races of the year to continue to fight on-track, earn more points, and conclude out strongest season to date in Formula 1.”

Grosjean was excluded from the results of the race after the stewards upheld a protest from Renault concerning the floor of Grosjean’s VF-18. The floor was found not to comply with Article 3.7.1.d of the technical regulations, as clarified by TD/033-18, regarding its radius of 50mm.

Renault technical director Nick Chester said the team is “satisfied” with the decision.

“Technical regulations – especially those introduced for safety reasons – must be observed strictly,” he said. “We are satisfied with the decision and I would like to thank the court and the FIA for their work on this matter. The team is now focused on the end of the season.”

The appeal court’s members included Jan Stoviek, Laurent Anselmi, Harry Duijm, Yves Fortier and Gerard Martin.
