The Rangers Fan Advisory Board have called for an independent review of Scottish refereeing following the League Cup final spot-kick furore.
Rangers were critical of the Scottish FA earlier this week after the two officials at centre of the controversy - Alan Muir and Frank Connor - were handed a return to action for Premiership fixtures.
Muir and Connor failed to award Philippe Clement's side a penalty when Vaclav Cerny were fouled by Liam Scales on the edge of the area. Clement has been critical of the decision since and Rangers released a strong statement on Christmas Eve after it was confirmed that Connor will run the line at Kilmarnock versus Aberdeen and Muir will be in action when Celtic face St Johnstone this weekend.
A statement from the FAB read: "We wholeheartedly support the stance taken by Rangers over recent failures in Scottish refereeing and echo the calls of the RSA for the club to continue its direct and robust approach in its dealings with the SFA on these issues.
"Sadly, the decision to reinstate inept officials so quickly to high profile fixtures following their inexplicable decision-making at the League Cup final comes as no surprise.
"The refereeing department at Hampden has clearly been emboldened by the mocking disdain that was shamefully displayed by the SFA's CEO lan Maxwell in a rare public appearance in the aftermath of the final.
"Stakeholders in Scottish football - not just Rangers - are also done a disservice when serious issues raised by member clubs around the professionalism of our officials are dealt with in such a flippant manner by the SFA President Mike Mulraney, who should hold himself to a far higher standard.
"It is surely time for a full, independent examination of the processes and governance of Scottish refereeing, including those responsible for administering and developing our officials. Rangers - and Scottish football - deserve better."
