Aston Martin driver Lance Stroll has lost seventh position at the Emilia Romagna Grand Prix after overtaking Pierre Gasly by cutting the Tamburello chicane.
Stroll had already failed on track in attempting to overtake the AlphaTauri, who was on slower wet tyres at Imola when he made his way past on lap 11 by skipping across the gravel trap, proceeding to pull away from the Frenchman.
After an investigation into the manoeuvre, the stewards deemed Stroll to have gained a lasting advantage, earning the Canadian a five-second penalty to drop him to eighth place
The stewards' report read: "The stewards heard from the driver of car 18 (Lance Stroll), the driver of car 10 (Pierre Gasly) and the team representatives and reviewed multiple angles of video evidence.
"The stewards were informed after the race of an alleged breach. Having reviewed the video and heard from the drivers, the stewards conclude that car 18 was not able to complete his pass on car 10 at turn 2/3 without leaving the track completely shortcutting turn 3 and returning on the track ahead of car 10.
"He then failed to give the position back. In hearing from the drivers the stewards accepted that car 18 was ahead of car 10 at the point he left the track, but that he was in that position because of a manoeuvre that he was not able to complete on the track given the wet conditions."
Stroll was also handed a penalty point on his super licence, taking his tally to four for the rolling 12-month period.
