Essendon needs to pre-empt this "ASADA clause"

If another club urges a player to use this clause to get out of an existing contract then, surely the EFC would be within its legal rights to sue the AFL, who also have joint duty of care of the players and failed to act.   Their decision not to act, when they first became aware of a supplement program and allowed the program to continue knowing players health and wellbeing could be endangered.  Could be interested if this was tested in court.
