Gordon Smith has revealed every Clydesdale Bank Premier League club has officially complained about referees this season.
The Scottish Football Association chief executive was reacting to yet more controversy involving clubs and officials in the SPL.
St Mirren manager Gus MacPherson tried unsuccessfully to get Alan Freeland replaced before their Scottish Cup replay win over Dundee United at Tannadice earlier this month.
St Mirren were also unhappy with referee Eddie Smith on Sunday for his award of a free-kick that led to Shunsuke Nakamura's late winner in their SPL clash.
But SFA chief Smith insists the Saints are not the only club to have complained about officials - and pointed out they all believe they are getting the thin edge of the wedge.
He said: "I've had a letter from every club in the SPL saying referees are biased against them. Clubs genuinely write in to say it.
"There's a consistency there - referees have got something against every team. But you can't have clubs dictating who referees games.
"St Mirren didn't officially complain about the referee. They just contacted us to say they didn't want him to be in charge.
"If they (St Mirren) had a problem with Alan Freeland they should have put in an official complaint about him before waiting until he was given a game involving them. Then it could have been dealt with.
"We are looking at that (Freeland complaint) to see if there is any way we can take it forward. We're waiting for the refereeing department to come back.
"But it's out the way now. He refereed their game and there was no complaint about him."
Much of the anger directed towards Nakamura was from Saints fans claiming the Japan international had gone to ground far too easily after a challenge by Buddies midfielder Gary Mason.
Smith, alluding to the incident, revealed the SFA will bring in their own rules to combat simulation for next season.
He said: "We have simulation as an agenda item for the IFAB (International Football Association Board) at a FIFA meeting in March.
"We're doing a feasibility study on it at the moment but we haven't announced any results. We'll talk about it more after we've put it to FIFA.
"But we will almost certainly be introducing our own form of simulation control next season."
