Inverness manager Terry Butcher criticised referee George Salmond following his side's 1-1 draw with Aberdeen in the Highland capital.
Butcher felt Owain Tudur Jones was wrongly shown a straight red card for a second-half challenge on Ryan Fraser.
He said: "It was never a red card for Owain. He got there late and the boy's just nicked in before him. It was a yellow card, but never a red card."
Caley Thistle took the lead from the penalty spot in the 67th minute through Richie Foran after Russell Anderson saw red for the Dons when adjudged to have felled Shane Sutherland when through on goal.
Butcher was then adamant Inverness should have had a second penalty for Mark Reynolds' challenge on Aaron Doran as the winger prepared to shoot, before Aberdeen salvaged a point when Cameron Smith headed home an equaliser six minutes from time.
"We go 1-0 up and have a great chance to make it 2-0, but the referee doesn't give the penalty. I spoke to the referee afterwards and he said Aaron Doran scuffed his shot before falling over. However, he's the only man in the planet who saw that," he said.
Aberdeen boss Craig Brown refused to speak about the referee's performance or comment on the penalty incidents, preferring instead to focus on a much-improved second-half display from his team that earned them a point.
He said: "I think it was a fair result. The first half was probably the poorest we've played this season, but I think you have to give credit to Inverness for that.
"Also, we were not switched on enough and when you start a game slowly then it is very hard to get that tempo back again. However, in the second half we got the ball down and played a lot better."
