Craig, I don't think that there is a problem with players asking why a decision was given. The player may not have seen the action that led to the decision and is asking just for clarification, or they are trying to understand why a ref is giving a certain call. I dont think that initially asking for an explanation or asking why a decision is given constitutes dissent. However, once you make it plain that a decison has been given or you give your explanation then continued questioning of that decision is dissent. I had two questions yesterday which I certainly did not feel were dissent but were only players wanting clarification. One player apparentlly fouled asked me "Come on ref, why was that not a foul." Not dissent in my view. My reply was that the tackle looked fair as the other player seemed to have got the ball and the "fouled" player fell over the attacker's feet. Once the explanation was given, any further questioning of it would have led to a stepped approach for dissent. Another situation was a handball decision by me. Offending player asks "How was that handball ref, it came off my side?" Again, a player just appearing to want clarification of my decision. I was happy to tell him that from my position it appeared that the ball had bounced from his side and made contact with his arm which was out at an unnatural position. No complaints from the player (which would suggest that it was handball) but any further challenge to my decision would have led to consideration for dissent. I know that we all have our own level of tolerance for dissent and abuse, but I personally think that cautioning a player just because they have asked why you have made a decision is quite a low level of tolerance. Obviously it all depends on how that question is asked of course.
