A FEDERAL Court trial into the Essendon supplements scandal is underway in Melbourne.

James Hird and his wife Tania arrived at the court building on Monday morning to be greeted by a large media contingent. 

Essendon chairman Paul Little and chief executive Xavier Campbell also arrived shortly before proceedings began at 10.15am. 

The 34 past and present Bombers players who have received show-cause notices are represented in court by lawyer David Grace QC. 

Essendon believes ASADA's joint investigation with the AFL was unlawful and their players should not receive show-cause notices.

ASADA says it is allowed to work with a sporting authority and James Hird and his legal team co-operated and therefore agreed to the joint investigation.

What they say: Catch up with Essendon, ASADA and the players' cases
