They would have to, no doubt about it (they wouldn't want to, however). NRL stripped the Storm of their two (I think it was) premierships. If the appeal is unsuccessful, AFL have to strip Jobe of his Brownlow. No ands, ifs or buts.
Read between the lines, Jen.
The AFL is now commencing its PR campaign to do exactly the opposite. The AFL has steadfastly refused to acknowledge the clear fact that doping has and is occurring. The AFL's stance is publicly say one thing and support the dope cheats as much as they possibly dare...and they dare plenty.
Anybody who thinks that Essendon are the only club involved in systematic doping is utterly delusional. Essendon is the unlucky team that got caught in publc.
Jobe will keep the medal and that will be an 'up yours' to ASADA / WADA. They can do that because nobody in government has either the integrity or the nads to hold them accountable. One thing I've seen first hand is if you are big enough, nobody in government will take you on because their is no political to go the distance in a stand up fight.
