If Essendon mount a legal challenge against the ASADA investigation it is pretty much saying that the players can't prove they are innocent parties but we reckon ASADA broke the law getting to the truth.
ASADA aren't going to pussyfoot around they will go for the jugular now the time for discounted sentences has passed. ASADA put their evidence in front of a former supreme court judge who agreed that they had more than enough, Essendon are rooted.
Look at the history of show cause notices worldwide with WADA, they don't hand them out for fun, nobody gets off.
