Suspended trainer Sam Kavanagh will again front stewards on Thursday as he and others charged present verbal or written submissions for penalty relating to their guilty pleas and or findings in the Midsummer Sun and raceday treatments inquiry.

Kavanagh has pleaded guilty or been found guilty of 23 charges by stewards for his involvement in the case.

Kavanagh’s charges cover a range of breaches including Midsummer Sun’s positives to prohibited substances cobalt and caffeine after winning the Gosford Gold Cup in January as well as raceday treatments to horses Centre Pivot, Palazzo Publico, Ceda Miss and Invinzabeel.

Harness racing identities John Camilleri and Mitchell Butterfield face six and five breaches of the Australian rules of racing while a former Kavanagh employee Michael O’Loughlin has five breaches, one a new charge for failing to appear during the hearing in early August.

The penalty hearings for Flemington Equine Clinic partner Dr Tom Brennan and his employee Aaron Corby will be held on September 18.
