Guenther Steiner has urged Formula 1 to consider permanent stewards after Romain Grosjean was penalised in Mexico.
The Frenchman was handed a five-second time penalty for cutting a corner while battling with Fernando Alonso for position.
The McLaren driver, though, escaped punishment despite later making contact with the Haas driver.
Haas team boss Steiner spoke with F1 race director Charlie Whiting after the grand prix and voiced his concerns about the inconsistent stewarding decisions.
“I’ve spoken to Charlie and we’ve had some constructive discussions,” Steiner said. “My biggest thing is the technicalities of what is wrong and what is right. That isn’t easy to find out, and it’s the consistency.
“You need to know what is happening and what is not happening with penalties, and that’s my biggest thing – every time it’s different.
“Romain gets five seconds for cutting the corner and then Fernando runs into him, hits his car, and destroys his race anyway and gets nothing. It’s like… explain it!
He added: “For me the only solution is to have permanent people there, who know what happens every week. I have no problem if they are then supplemented by additional people or whoever, but there needs to be somebody consistent who knows what happened a year ago, two years ago, last week.
“You need to be accountable for that job, there’s too much at stake. This is a big sport.
“I’m not blaming the guys because it’s not their job, but you cannot have one day one decision and another day another one and say ‘yeah that’s alright’! And for sure it’s worse with the smaller teams on the grid because they care less about them.”
