Red Bull boss Christian Horner was searing following the US Grand Prix Steward's decision to penalise Max Verstappen and deprive the Dutch driver of a well-deserved podium finish.
Verstappen carved through the field from the outset after starting 16th following a grid penalty, with his charge ending hot on the heels of Ferrari's Kimi Raikkonen.
The Red Bull driver successfully challenged and overtook the Finn on the inside of Turn 17 on the final lap, securing an impressive third place finish.
But a five second penalty for exceeding track limits and gaining an advantage wreaked havoc on his podium plans.
"There's been cars going off track all day today and no action at all, so I think it would be unbelievably harsh to give Max a penalty," Horner told Sky Sports.
"It's wrong. We'll have a look at it, but for me it was fair, hard racing. I think that's a bad judgement by the stewards to have made that call.
"He did it the hard way. We've seen cars off track all day today, all weekend, so to penalise him at this stage, that's not right."
