Neil Lennon called for consistency from officials after Celtic were denied a late penalty in their 1-0 Clydesdale Bank Premier League defeat by Dundee United at Tannadice.
The Hoops boss is currently serving a three-game touchline ban - with another three-game ban suspended - for running on to the pitch at the end of the Scottish Cup semi-final against Hearts at Hampden last month to confront referee Euan Norris, who had awarded the Tynecastle side a controversial penalty which saw Celtic dumped out of the cup.
With Celtic trailing 1-0 to United on Sunday, the Hoops' claims for a spot-kick when Emilio Izaguirre's cross hit the hand of Keith Watson were ignored, and Lennon said: "What is the difference between the penalty given against us in the semi-final and that handball?... You've got to be consistent."
