Formula One leaders McLaren have been stripped of all their points in the 2007 constructors championship and fined $100 million as a result of a spying controversy, the governing body confirmed on Thursday.
However, championship leader Lewis Hamilton and team mate Fernando Alonso have kept their points in the drivers' championship.
"The WMSC (World Motor Sports Council) has stripped Vodafone McLaren Mercedes of all constructors points in the 2007 FIA Formula One world championship and the team can score no points for the remainder of the season," the FIA said.
"Furthermore the team will pay a fine equal to $100 million, less the FOM income lost as a result of the points deduction," it added.
The decision means Ferrari, currently second overall and 57 points clear of BMW Sauber with four races remaining, look certain to be crowned champions.
Asked if justice had been done, the president of the FIA Max Mosley said "Yes".
