Red Bull advisor Helmut Marko has stated that the team are appealing the stewards' decision not to penalise Lewis Hamilton over an alleged yellow flag breach at the Saudi Arabian Grand Prix.
Hamilton allegedly failed to respect double waved yellow flags in Saturday evening's session at the Jeddah Corniche Circuit, but was cleared after the stewards recognised a marshalling system error.
However, speaking on Austrian TV after qualifying, Marko declared a Red Bull appeal, referring to the five-place grid penalty Max Verstappen received last time out in Qatar for his own yellow flag transgression.
"We have appealed against this decision," Marko told Servus TV.
"In Qatar, Max gets a five-place grid penalty. Here, suddenly a yellow is no longer a yellow."
Mercedes drivers Lewis Hamilton and Valtteri Bottas locked out the front row of the grid in qualifying at the Jeddah Corniche Circuit, with Verstappen having to settle for third after crashing out on his final lap.
