I am not weighing in on the Lance Justice case at all as I have not followed the facts closely enough.
I would however add this, the appeal process is important for many reasons even if it is only to test the validity of the rule.
There is no more obvious example than the Geoff Small Changeover case in NSW where at appeal it was argued that the rules as they were worded at the time did not cover this substance as it was not listed in the rules as it was an Antifibrinolytic, ( tranexamic acid) and it only had an effect on the blood system which was also not covered in the rules..
History shows Small won the appeal and low and behold the rules are changed.
Without this appeal the loop hole in the rule remains open.
