During a committal mention hearing in the Warrnambool Magistrates Court on Friday, Melbourne lawyer Tony Hargreaves requested leave to cross-examine Warrnambool police crime scene officer Shannon Kavenagh.

Three Warrnambool police officers - Benjamin Timpson, Gregory Cressall and Lachlan Barr - have been charged with negligently causing serious injury following a following an Independent Broad-based Anti-corruption Commission investigation called Operation Blackmore.

The officers are alleged to have attended at Warrnambool resident Chris Karadaglis' home due to a noise complaint in late November, 2017.

It's alleged that during his arrest Mr Karadaglis suffered a neck injury which left him a quadriplegic.

Mr Hargreaves said it was sought to explore how Mr Karadaglis' trauma was sustained.

Magistrate John Lesser questioned how a crime scene officer could shed light on such an injury.

He said crime scene officers looked for signs of all sorts of things, but not usually broken necks.

Mr Hargreaves said it would be submitted the injury to Mr Karadaglis was suffered on or about November 28, 2017.

He said there were holes in the plaster walls of Mr Karadaglis' home consistent with the size of a head.

The lawyer said it was claimed in one of the holes there was blood found.

"We believe tests were carried out," Mr Hargreaves said.

"A person put their head into a hole in the wall, a hole in the plaster.

"Shannon Kavenagh either did it or observed that during the experiment or test.

"There is no reference on the brief (of evidence) to that taking place."

Mr Hargreaves said a blood sample could be important and there was no analysis of the blood contained in the brief of evidence.

The magistrate said a request should be made to the case's lead investigator.

"It seems a long bow," Mr Lesser said, before adding he would be happy to review the situation if further evidence came to light.

The case has been adjourned to a special hearing on November 22 while a committal hearing for 10 days is scheduled for between September and December next year.

It's expected to be a complex committal hearing with lawyers for each of the three police officers potentially cross-examining each witness.

It's expected a Melbourne magistrate, or at least a magistrate from outside the south-west, would preside over the committal hearing.
