Melbourne lawyer Jackson Taylor has lodged a writ against outgoing AFL chairman Mike Fitzpatrick and chief executive Gillon McLachlan, alleging acts of deceptive or misleading conduct during Essendon's supplements saga.

Taylor has lodged papers in the Victorian Supreme Court, and now awaits an AFL response.

The statement of claim includes allegations the AFL deceived the public over both the integrity of the joint investigation conducted by the AFL and the Australian Sports Anti-Doping Authority (ASADA) and the AFL's responsibilities for player health and safety.

It cites interviews McLachlan has done with journalists and alleges "the AFL contributed significantly to the exposure of players to risks to their health and safety" by failing to regulate against the use of peptides before September 2012.
