THE ASADA scandal has moved to the NSW District Court, with suspended winger Sandor Earl this week beginning legal action against the doctor who injected him with banned peptides in 2011.

The Daily Telegraph has obtained a copy of Earl's statement of claim against Dr Ijaz Khan, who is being sued for professional negligence after allegedly assuring the former Panthers and Raiders flyer that CJC-1295 was not prohibited under the WADA Code.

The development comes as The Daily Telegraph yesterday revealed the NRL has entered the final stage of its investigation into Cronulla's 2011 supplement program, which could see bans and fines against Sharks staff handed down within the next month.

On Wednesday Earl's lawyer, Tim Unsworth, lodged the statement of claim, which alleges that Dr Khan:

● Purported to administer a CJC-1295 - a substance not approved for human use;

● Did not obtain from a reliable source such as a qualified chemist;

● "Falsley advised" Earl that CJC-1295 was not a prohibited substance;

● Failed to advise Earl about the "risk of harm to his health" posed by the CJC - 1295 injections.

Earl is claiming an unspecified sum of damages from Dr Khan, arguing his treatments were negligent and also amounted to personal trespass because his consent to the injections was based on a belief that the substance was WADA-approved.

On August 29, the NRL issued the 24-year-old with an infraction notice for attempted use and trafficking of a banned substance, offences that carry a maximum four-year ban.

Earl is attempting to have his sentence reduced to 12 months by providing ASADA with "substantial assistance" that will lead to bans for others. Earl has previously alleged that sports scientist Stephen Dank introduced him to Dr Khan while he was recovering from a double shoulder reconstruction in mid-2011.

The statement of claim also alleges that Dank supplied Earl with a vial that the sports scientist said contained CJC-1295. Dank has repeatedly denied providing any players with banned substances and is not a party to Earl's litigation.

According to allegations contained in the court document, Dank handed over the vial "on or around" September 12, 2011 - about six weeks after his first treatment at Dr Khan's Injury Care medical clinic in Cabramatta.

Earl claims that Dr Khan advised him the first batch of CJC-1295 had almost run out and to told him to arrange for Dank to deliver more.

Instead, Earl personally delivered the vial from Dank's clinic in Mascot to Dr Khan's rooms at Cabramatta.

"The plaintiff's reputation has been damaged by his provisional suspension and, as a result of that damage, he is unable to earn income," the statement of claim reads.

Dr Khan did respond when contacted for comment last night. He has 28 days to respond, with the matter set for re-hearing on January 28, 2014.
