In May 2014 the Fédération Internationale de l'Automobile (FIA) has reported an anti-doping rule violation against Marc Amez-Droz (the Driver) after his sample tested positive for the prohibited substance hydrochlorothiazide. After notification the FIA ordered a provisional suspension and the Driver was heard for the FIA Anti-Doping Disciplinary Committee (ADC).
The ADC concludes that an anti-doping rule violation has been established and therefore decides on 25 September 2014 to impose a 2 year period of ineligibility on the Driver, starting on the date of the sample collection, i.e. on 25 May 2014. Also the ADC decides for disqualification of the competitive results obtained by the Driver during the event, with all of the resulting consequences, including forfeiture of any trophies, points and prizes.
