Sep.20 (GMM) F1's governing body has confirmed that Friday is the deadline for McLaren to appeal its $100m fine and championship expulsion.

The FIA said in a statement on Thursday that it released the information following a "number of enquiries from the international press".

"After conferring with the Secretariat of the International Court of Appeal the FIA understands that the deadline for such an appeal is 1700 hrs (CET) on Friday, September 21st," the statement read.

McLaren earlier this week withdrew its scheduled appeal against a stewards' decision handed down at the Hungarian grand prix.

Team boss Ron Dennis in Spa-Francorchamps suggested that he wanted "closure" on the various controversies that have dogged the Mercedes-powered team in 2007.
