This paper considers the application of the doctrine of estoppel to ‘shield’ from contract-based prosecution those players of the Cronulla Sharks and Essendon Bombers implicated in recent accusations of doping. The arguably different application of estoppel as between the clubs (which are contractually entitled to punish players for doping) on one hand, and the organising bodies of the National Rugby League (NRL) and the Australian football League (AFL), on the other, is also considered.
