Florian Hilgart, 41, is charged with intentionally causing injury, recklessly causing injury and unlawful assault for using the extendable baton against the then-16-year-old, who cannot be named for legal reasons.

On Thursday, Magistrate Susan Wakeling found there was enough evidence for Senior Constable Hilgart to stand trial.

Senior Constable Hilgart, who is currently suspended with pay, stood as he was addressed by the magistrate.

"Thank you your honour. I wish to plead not guilty," he said.

Charges followed corruption watchdog interviewing teenager

Senior Constable Hilgart was charged with assaulting the teenager after Victoria's Independent Broad-based Anti-corruption Commission (IBAC) interviewed the boy last year.

According to his statement to IBAC, the boy was getting a lift home with his uncle when police stopped the car in Thornbury about midday on New Year's Day 2018.

"My uncle was driving around back streets trying to get away from the police," he told investigators in the statement.

"When my uncle turned into a street … the car conked out and wasn't going anywhere," he said.

"My uncle was swearing because he was going to get caught. I could hear the police sirens as they came closer."

In court Senior Constable Hilgart's barrister, Marcus Dempsey, asked the teenager, who is now 17, how he would describe his uncle's driving.

"Um, erratic," he said, via videolink from Parkville Youth Justice Centre.

"Could you hear him call the police 'f***ing dogs'?" asked Mr Dempsey.

"Yeah," the boy said.

When asked by Mr Dempsey whether that was also a term he used for police, the boy said it was.

Passer-by filmed incident on mobile phone

The teenager said that when police got to the car, they smashed the windows with their batons.

Instead of fleeing, the boy told IBAC investigators he remained where he was.

"I had plenty of time to run but I just stood there, I put my hands up to show that I wasn't resisting," he said.

"The police officer then turned to me and said, 'Get the f*** on the ground, c***'."

Senior Constable Hilgart is then alleged to have stood over the boy and hit him with the baton several times.

"When I was hit with the baton, I felt pain each time I was hit," the boy said in court documents.

"I just laid there, I didn't try to get away or fight back or resist the officer.

"The police officer then picked me up by the shirt collar, and dragged me over to the gutter and cuffed me."

The incident was filmed by a passer-by on their mobile phone.

The boy was not charged over the incident but said he was sore for about a week afterwards.

"I had a sore elbow and couldn't straighten my arm properly," the boy said.

'You ask some dumb questions,' boy tells lawyer

In court, the hearing had to be adjourned briefly after the teenager became frustrated with Mr Dempsey's line of questioning, which probed how many times he was struck and on which side.

"I can't even remember, bro," said the boy.

"You ask some dumb questions, bro."

The boy's complaint against Senior Constable Hilgart was mentioned to other officers on the day he was allegedly assaulted, but the accounts are conflicting.

Detective Senior Constable Michelle Belaj was on duty and took the boy back to the police station.

In a statement to the court, she said he told her his arm was sore.

"I asked if he needed medical attention, to which he declined," she said.

"I asked what had happened to his arm. I believe he stated he had been thrown around in the vehicle."

But Detective Sergeant Craig Armstrong received a different account, which he also detailed in a statement tendered in court.

"I said, 'Are you satisfied with the way you have been treated by police during this investigation?'" he told the court.

"He said, 'Yeah these guys were OK, but when I was arrested by the uniform guys, they hit me with their baton and I wasn't even resisting."

Detective Sergeant Armstrong told the boy he could make a complaint.

"He said, 'Yeah thanks. That's the last f***en time I get a lift anywhere with my uncle.'"
