Walter Smith believes there is no need for the Scottish Football Association to change their appeals procedure — and the Rangers manager insists referees are honest enough to admit when they have made a mistake.
The current system sees match officials review incidents again and, if they concede they originally called it wrong, the appeal is then reviewed by an independent panel.
If the referee maintains he was right the matter is closed, as was the case with Celtic captain Scott Brown.
“That's the way it is, with the referee having the final decision after looking at it again,” said Smith.
“I do think, if a referee goes in and has a look at it and is honest enough about it, that's sufficient.
“I don't think there is any great need for a change. I don't think a referee will be frightened to change his mind if he sees that he's wrong.”
Rangers face St Mirren for the fifth time so far this season in the Clydesdale Bank Premier League today and Smith said: “I don't think the game will be very much different from the ones we have had in recent weeks.”
He also reiterated his desire to see players take more responsibility for their actions off the pitch as Allan McGregor continues to dominate the front pages.
The goalkeeper hit the headlines again this week when his fiancee was arrested for wasting police time and an investigation into an alleged assault on the player was dropped.
“Footballers have got to react to that, that's the situation,” he said. “They have that aspect of their life to look after as well and that's a responsibility every player has to take.
“They all know the unwritten rules, as well as the written ones, and the unwritten ones are ones they have to follow as well.
“They all know what they should be doing and what they shouldn't be doing.
“It's up to them to try and figure out which is which. Some of them struggle.”
