The Williams Formula 1 team has decided to drop its appeal against Felipe Massa's exclusion from the Brazilian Grand Prix.
The team was found to be in breach of the FIA technical and sporting regulations, FIA international sporting code and the instructions of Pirelli after the right-rear tyre on Massa's car was discovered to be 27 degrees centigrade above the allowed maximum of 110 degrees.
After finishing in eighth place in his home race at Interlagos, Massa was ultimately excluded from the results, only for the team to launch an immediate appeal.
Williams performance chief Rob Smedley claimed the appeal was based on three independent temperature readings that showed Williams was "within the limits set by Pirelli and the prescriptions for this event".
After further consideration, however, while believing it had a strong case, Williams has chosen not to take the matter further, believing any case will have a bearing on its 2016 preparations, and with legal costs to consider.
A Williams statement to Autosport read: "Following detailed consideration the team has concluded that despite not agreeing with the exclusion and believing it has sufficient evidence with which to successfully contest the ruling, it will not formally appeal the decision as a hearing date is unlikely to be available until after the end of the season, impacting a time when the team wishes to turn its attention to its 2016 campaign.
"Given the financial climate of the sport, and the fact that the decision does not impact the team's constructors' championship position, it has been decided that this would be an unnecessary cost to endure."
