Volvo Ocean Race leaders Team Telefonica could be docked points if they're found guilty of an alleged breach of the sail limitation rule on leg four to Auckland - drastically altering the complexion of the race.
The Spanish team have been accused of carrying an extra storm jib during leg 4 from China to Auckland, and will face a hearing before the international jury when they arrive in Brazil next month.
It is believed French team Groupama have video evidence of the breach, but skipper Franck Cammas did not lodge an official protest, instead referring the matter to race management upon their arrival in Auckland.
But it wasn't until last Sunday, nearly three hours after the fleet had left for Brazil, that the chief measurer lodged a report with the international jury.
The jury will schedule a hearing during the next stopover in Itajai, with the date to be confirmed closer to the time.
