The FIA's Court of Appeal reconsidered the ban on Renault's participation at the European grand prix due to the "collateral damage" of the stewards' ruling.
FIA considers race ban 'damage'
"The stewards of Hungary had not measured the consequences of this sanction on Renault and Alonso," Carlos Gracia, Spain's highest ranking motor racing official who attended the Paris hearing on Monday, told the AS newspaper.
Gracia said the four judge-panel Court, in replacing the race ban with a $50 000 fine and written reprimand, had considered the "collateral damages that the stewards of the Hungaroring did not consider".
He also revealed that observers for the Williams and McLaren teams sat in on the Monday morning appeal.
The FIA said late on Monday that the reasons for the Court's decision will be published shortly.
