The Haas Formula One team lost on Friday a bid to overturn a stewards’ decision that excluded French driver Romain Grosjean from sixth place at the Italian Grand Prix in September.
The governing FIA’s International Court of Appeal upheld the original decision and confirmed the exclusion a day after a hearing in Paris.
The court said a detailed explanation would be issued at a later date.
The U.S.-owned team expressed disappointment with the outcome.
“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 our strongest season to date,” said team principal Guenther Steiner in a statement.
Ferrari-powered Haas are fifth in the constructors’ championship, 30 points behind Renault, who had questioned the legality of the floor on Grosjean’s car at Monza.
The Frenchman’s result, worth eight points, had put Haas ahead of Renault in the standings but his exclusion dropped them back to fifth.
Renault argued that Haas had not complied with a technical clarification issued to teams in July, and presented photographic evidence to back up their argument.
“Technical Regulations — especially those introduced for safety reasons — must be observed strictly,” said Renault chassis technical director Nick Chester, expressing satisfaction with the decision.
Haas have ruffled feathers in Formula One by striking a close technical partnership with Ferrari and contracting out as much as possible, allowing them to be competitive with fewer staff than rivals, who design and build everything in-house.
