The Czech privateer was handed the penalty after the seal on his car's rear differential was found to be broken.

Prokop just missed out on scoring points by finishing 11th and was left furious, threatening to leave the championship.

However, once the team returned to its base, a check of the parts suggested the seal was not broken, and the new evidence was brought forward to the FIA Technical Delegate.

FIA's statement read: "Upon return back home of the team of Competitor No. 21 [Prokop] after Rally Italy Sardegna and after checking the part in question, the Competitor's representative informed the FIA that they now discovered that the seals in question are no destroyed and that they wanted to bring forward new evidence.

"Upon the request of the FIA, a check was then performed by Mr. Josef Stransky (ACCR Technical Commission President) and Mr. Adam Elias (ACCR Secretary General) and their report confirmed that the seals on the rear differential of car no. 21 effectively are unbroken."

After clearing his penalty, Prokop is classified as ninth.
