Timo Glock and Jarno Trulli have been stripped of their grid positions for the Australian Grand Prix for a flexible wing infringement.
Glock had qualified sixth on the grid, with Jarno Trulli two places further behind, for their Toyota team at Albert Park.
However, following post-qualifying technical inspections by the FIA, it was found that the team's rear wing elements were in breach of the rules.
A statement issued by the FIA said: "The Stewards have received a report from the Technical Delegate that the upper rear wing elements of cars No. 9 and 10 are showing extreme flexibility in contravention of Article 3.15 of the 2009 Formula One Technical Regulations.
"The Stewards have heard the explanation from a representative of Panasonic Toyota Racing and have examined the cars in question.
"The Stewards concur with the opinion of the Technical Delegate and find the cars contravene the requirements of Article 3.15 of the 2009 Formula One Technical Regulations.
"It is the Stewards decision that cars number 9 and 10 be excluded from the Qualifying Session Official Classification."
Article 3.15 of the technical regulations states that wings must not have 'any degree of freedom' and 'remain immobile in relation to the sprung part of the car.'
The results mean that Trulli and Glock will start the race from the back of the grid.
Toyota said it will not appeal the decision.
