A Victorian driver jailed for crashing into a police car at nearly 100km/h and sending an officer flying will be allowed to appeal his conviction.
Andrew Hutchison was speeding along the Surf Coast near Geelong in November 2018 when he caused Sergeant Anthony French to be thrown into the air.
The officer survived but was left with post-traumatic stress disorder.
Hutchison was granted leave in Victoria's Court of Appeal on Tuesday to seek to have his conviction overturned.
He was also granted leave to appeal his maximum four year and nine month jail sentence.
Hutchison previously admitted recklessly causing injury, exposing an emergency worker to risk by driving, dangerous driving and damaging an emergency vehicle.
Aged 21 at the time, he was driving about 130km/h. His family had called emergency services with concerns about his mental health.
Police called Hutchison to try to reason with him and used throw sticks to deflate his tyres in an unsuccessful bid to make him stop.
Sgt French ran behind his police car for protection as Hutchison swerved at him.
Hutchison hit the brakes but collided with the vehicle at 98km/h.
The impact of the crash, captured by police helicopter footage, threw Sgt French a significant distance into the air.
His injuries were limited to a fractured foot and a finger as well as bruising, which the sentencing judge labelled astonishing.
Hutchison nearly ran over the officer as he lay on the ground, County Court Judge Gerard Mullaly said last May.
"In blunt terms it was truly horrific," he added.
"How the victim was not killed or very much more seriously injured is astonishing and a fortunate blessing, for the victim primarily but also for you."
Hutchison was found to be on the borderline for an intellectual disability.
Justice Chris Maxwell granted him leave to appeal. The case is due to return to the Court of Appeal at a later date.
