Due to the doubts expressed by Ferrari, McLaren and Mercedes AMG, the FIA is planning to decide about the controversial holes in the Red Bull's floor before Canada.
No official post-race protest have been placed, but the three top teams doubt about the legality and claim for clarifications.
An FIA spokesman explains: "Red Bull have not been asked to change anything yet. However, there is a difference of opinion over interpretation of a regulation, which we intend to clarify our position on during the next days."
The issue is about the holes ahead of the rear wheels of the RB8 Red Bull.
The spokesman added: "We think there are arguments on both sides so a position will have to be taken."
