On 1 August 2007, Ron Dennis, in an open letter to the president of the Italian motorsport authority Luigi Macaluso, accused Ferrari of giving a false and dishonest version of events and further that the car used to win the 2007 Australian Grand Prix was illegal. McLaren learned of the "illegal" floor device from Nigel Stepney, with the team describing this contact as whistle-blowing. However the team insists that following this incident, Jonathan Neale instructed Coughlan to cease contact with Stepney. McLaren accuse Ferrari of trying to blur this "whistle-blowing" of which McLaren was aware, with Coughlan's possession of the 780 page Ferrari dossier of which it insists it was not aware.
