Some corrupt betting charges against suspended racehorse trainer Jarrod McLean may be tossed out because there appears to be little evidence supporting them, a magistrate says.
McLean allegedly placed corrupt bets on horses he's accused of helping torture alongside his then-boss and Melbourne Cup-winning trainer Darren Weir in the lead-up to the 2018 Cup.
McLean, Weir and a stablehand were allegedly part of an illicit training regime to deceive racing officials during that year's Spring Racing Carnival.
But magistrate Ron Saines has singled out two of the 17 charges against McLean, saying they "have likely got some serious deficiencies".
The 39-year-old allegedly used the secret training regime to pass on information for corrupt betting on Yogi at Warrnambool on the day of the Cup.
McLean faces a similar charge for allegedly giving another man, retired jockey William Hernan, corrupt information relating to Cup runner Red Cardinal, also for betting purposes seven days prior.
Mr Saines questioned in Ballarat Magistrates Court on Wednesday the evidence used to support those charges and flagged the possibility they may be dismissed.
The court was told this could also lead to Hernan being cleared of the single charge against him, for a corrupt bet he allegedly placed on Red Cardinal for a November 2 race.
Meanwhile, McLean, Weir and stablehand Tyson Kermond together face 36 criminal charges relating to Red Cardinal, Yogi and a third horse, Tosen Basil.
The animals were allegedly tortured with poly pipes and shock devices or "jiggers" during the secret training regime as part of a conspiracy to cheat and defraud racing stewards.
Each man disputes the charges against them.
Acting for Weir, Ian Hill QC argued there was no conspiracy. And even so, he said breaching the rules of racing did not amount to a criminal offence.
Mr Saines expects to rule on the case on October 19.
