Leading trainer David Hayes will on Thursday face a reconvened Racing Victoria Limited (RVL) stewards' inquiry into the use of shockwave therapy on Poison Ivy which led to her withdrawal from a race at Moonee Valley last month.

The inquiry was opened at the meeting on November 20 when stewards ordered the late withdrawal of Poison Ivy from the Tatts Group Handicap.

They were acting on a report from RVL's compliance assurance team that the filly had received shockwave treatment therapy two days prior to the meeting.

Under Australian Rule of Racing 65H, a horse that has been subjected to shockwave treatment therapy is ineligible to race or trial in the seven days following such treatment.

Evidence was taken on the night from Hayes' stable manager Gary Fennessy and veterinarian Dr David McKellar, the employer of Dr Eoin Kelly who administered the treatment.

Hayes, who was in Perth on the night of the race, has been asked to attend Thursday's inquiry at 4.30pm (AEDT).

Shockwave therapy was the focus of a controversial aftermath to the 2008 Melbourne Cup when it was found that runner-up Bauer had been treated within seven days of finishing second to Viewed.

The English stayer was treated in the Sandown quarantine centre by an RVL veterinary surgeon.

Bauer's placing was unaffected after stewards accepted that trainer Luca Cumani was entitled to assume the vet knew the local rules.

Electro shockwave treatment is widely used around the world where it is allowed up until race eve in most jurisdictions.
