McLean had argued police didn't have the right to give Racing Victoria information relating to the January raid at Yangery.

But Supreme Court Judge Melinda Richards this morning determined Victoria Police acted lawfully when it handed the information over.

McLean went to court in a bid to stop Racing Victoria charging him based on the information received from police or relying on it in any disciplinary proceedings.

The 38-year-old was charged by Racing Victoria in February with possessing an electrical apparatus, known as a jigger, capable of affecting the performance of a horse, and conduct prejudicial to racing.

Earlier this month he was also charged with 16 criminal offences, including conduct that corrupts betting outcomes, animal cruelty and possessing cocaine.

Melbourne Cup-winning trainer Darren Weir was also charged with multiple counts of engaging in torturing, abusing, overworking and terrifying a thoroughbred race horse, and causing unreasonable pain or suffering to a thoroughbred race horse.

Earlier: Yangery horse trainer Jarrod McLean argues police didn't have the right to give racing authorities the evidence they collected during a raid of his Victorian stables.

The suspended trainer is due to learn on Friday if Supreme Court Justice Melinda Richards agrees.

The 38-year-old claims police unlawfully passed on information to Racing Victoria after a raid on his Yangery stables in January.

It means the regulator could slap McLean with charges of over-administering a prohibited substance to a horse to affect its performance in a race and failing to give evidence.

McLean's barrister previously told Justice Richards an injunction should be granted preventing the racing body laying charges.

"The racing authorities have had information relayed to them ... which we contend is abuse of power and an unlawful disclosure by police," Andrew Broadfoot QC argued last month.

But lawyer's for the police insist police acted in the public interest to maintain the integrity of the industry.

"Who wants to have a bet in the race when the participants in that race are cheating?" barrister Paul Holdenson QC, acting for police, asked.

McLean was charged in February with conduct prejudicial to racing and possessing an electrical device known as a jigger, suspected of being used to shock horses.

Last week police charged him with animal cruelty offences, corruption and possessing cocaine.

Racing Victoria subsequently suspended him during a closed-door hearing.
