パトリック・ヘッド
Following the court's decision, an appeal was lodged by the state prosecutor against Patrick Head and Adrian Newey. On 22 November 1999, the appeal absolved Head and Newey of all charges, stating that no new evidence had come to light (there was missing data from the black box recorder on Senna's car due to damage, and 1.6 seconds of video from the onboard camera of Senna's car was unavailable because the broadcaster switched to another car's camera just before the accident), and so under Article 530 of the Italian Penal Code, the accusation had to be declared as "non-existent or the fact doesn't subsist". This appeal result was annulled in January 2003, as the Court of Cassation believed that Article 530 was misinterpreted, and a retrial was ordered. On 27 May 2005, Newey was acquitted of all charges while Head's case was "timed out" under a statute of limitations. The Italian Court of Appeal, on 13 April 2007, stated the following in the verdict numbered 15050: "It has been determined that the accident was caused by a steering column failure. This failure was caused by badly designed and badly executed modifications. The responsibility of this falls on Patrick Head, culpable of omitted control". Even being found responsible for Senna's accident, Patrick Head was not arrested, as the verdict was delivered past the Italian statute of limitation for manslaughter.
