Notwithstanding the exchange between the respondents, it is actually a strange situation.
Based on what has been reported [elsewhere], Andersen has been given a penalty of one game suspension [which implies he has been found guilty] that can be reduced to a fine if he 'pleads guilty' [which implies he might not be].
Seems to sound like the only way is up [i.e., a stiffer penalty] if he goes down the tribunal path, but maybe that is exactly what the 'powers that be' want him [and us] to think to avoid a tribunal exercise that would lead to more scrutiny of the system.
Based on what I saw on TV at the time [feet off the floor, dual forearms to the neck or head] I'd suggest he would probably be unwise to test the system.
