I think an Appeal Panel of three is chosen from a pool of referees/ex referees, former players and one other. You are right in that the referee's view, as taken into acount by the panel, carries more weight than it should i.e. if the referee changes his mind or not. If the Appeal is deemed to be independent, fair and just then Thomson's explanation should be given equal weight to the evidence submitted by the appellant, in this case, our club. However I'm not sure that will happen.
Two things stand out for me about yesterday's incident. Firstly, his view of the incident wasn't clear but yet he quickly and unhesitatingly issued a red card. If I was on the panel I'd be asking him about his view of the incident, whilst replaying it on a screen. Secondly, he clearly indicated a stamp and I'd want to know if he still considered it to be a stamp by Kipre . Presumably thats why Kipre was given the card?
