Sorry but that is a load of nonsense.
The ref only gives the penalty if he is sure an offence has been committed. If it takes a review of all the angles to determine if it's a penalty or not how can you expect him to give it? He cannot guess it's a penalty.
Doh - you ought to read things properly before responding.
You are simply agreeing with me - I was not suggesting that he "...takes a review of all the angles to determine if it's a penalty or not...." - that is not possible in the current system
In real-time it simply has to be given as a penalty - because in real-time and from his angle it simply cannot look like anything other than a clear penalty.
There is not really any room for a different decision - unless he is guessing - or deciding simply that he does not want to give it for other reasons
