The Malaysian Grand Prix race stewards have rejected Spyker's protest against Scuderia Toro Rosso after they decided they were unable to rule on the matter.
Following lengthy deliberations overnight, the stewards felt that with the customer car matter already being looked at in arbitration, it should be dealt with by the courts only.
A statement issued by the FIA on Friday said: "Spyker have made an application for arbitration and must by definition therefore be deemed to accept that a dispute such as this ... does not fall within the range of disputes to be settled under the FIA 2007 Formula One Sporting Code.
"It is considered therefore that it would be entirely inappropriate for the Stewards to involve themselves in a matter being dealt with at the instigation and election of the Protestor, Spyker, in an entirely different forum.
"It follows, that this Protest is inadmissible and the Protest fee is accordingly returned."
