Dundee United have made an official complaint to the Scottish Football Association after being angered by referee Mike McCurry's performance in the league match against Rangers earlier this month.
By doing so, the club have fulfilled their commitment not to back down over the issue after claiming they were wrongly denied two goals at Ibrox in a match Rangers won 3-1.
McCurry admitted following the Clydesdale Bank Premier League game that he had called the two crucial decisions wrongly in favour of the home side.
He turned down a strong penalty claim when Rangers defender David Weir clashed with Noel Hunt, while a deflected strike from Danny Swanson was incorrectly disallowed for offside.
McCurry claimed he was unsighted at the penalty incident and had been wrongly advised by his assistant for Swanson's 'goal'.
A statement from United confirmed: "Dundee United FC has today lodged a formal complaint with SFA chief executive Gordon Smith in connection with the refereeing decisions in a number of controversial incidents during the Rangers v Dundee United match at Ibrox on Saturday, May 10 2008. The club is now awaiting the response of the SFA."
Levein last week suggested professional referees should be considered by the SFA, who have responsibility for match officials in Scotland.
Levein also said in the aftermath of the match: "It's the most annoyed I've been in all the time I've been in the game.
"These are not innocuous things like corners or throw-ins, these are goals and penalties.
"This is my livelihood. It's as basic as paying the mortgage to what holiday I go on."
SFA chief executive Smith said last week the SFA were "hugely disappointed" by United's response to the refereeing errors and stressed it was "completely unfair" to suggest the decisions were driven by an agenda.
