Selective refereeing Celtic v Motherwell

Celtic winning 1-0 and playing nerously. Referee Stephen Finnie and assistant referee David Watt ignore late challenge on Mark Wilson despite having a clear view of it. Play goes up the park where Lasley of Motherwell puts in a late challenge from behind on Emilio Izaguirre who is escourting the ball out for a goal kick, Motherwell player yellow carded for the foul but corner kick awarded to Motherwell, assistant referee Stuart Stevenson in agreement.

Scott Brown who had already been booked realises he wont win the ball and pulls out of a tackle, slides into Motherwell player who kicks Scott Browns knee. Assistant referee has a clear view of it and flags, referee rushes to the sceen to give Scott Brown his second yellow card and is suspended for the Glasgow derby. FT 1-0

A night with many unexplainable incidents like this, all in favour of the away team.

Who is appointing the referees?

Who is supervising them?

Who are they out to impress?
