Guenther Steiner has been hauled in front of the stewards at the Spanish Grand Prix after he called for Formula 1 to do away with "laymen" in the role.
Never one to shy away from speaking his mind, the Haas chief voiced his frustration on Thursday over a penalty handed to Nico Hulkenberg last weekend in Monaco. The German driver was penalised for an incident on the first lap of that race, but Steiner insisted there was "no collision".
He went on to tell reporters in Barcelona: "Every professional sport has got professionals being referees and stuff like this. It's like, F1 is one of the biggest sports in the world and we still have laymen deciding on the fate of people that invest millions in their careers."
