Jamie Saxon was last year found guilty of killing tourist Dominik Schulze during a road rage argument on Milton Road in 2017.

Mr Saxon had pleaded not guilty to murder, arguing he was trying to defend himself and his then-partner, when he stabbed Mr Schulze.

The court heard the tourist was intoxicated, standing in the middle of the road with his pants down when he was clipped by the car being driven by Mr Saxon's then-partner.

An altercation broke out by the side of the road and Mr Saxon stabbed Mr Schulze four times with a fishing knife, the court heard.

The Court of Appeal has now ruled Mr Saxon's conviction be quashed and has ordered he be retried at a date to be set.

The court heard the jury in his trial had been provided with a document that contained an error relating to the elements of self defence.

Justice Peter Davis said the judge had correctly advised the jury during her summing up, but the document held the error.

He told the court witnesses had given evidence at the trial that Mr Schulze was much taller than Mr Saxon, that he had thrown punches at him and was aggressive and intoxicated at the time.

"The appellant told police that he was terrified, that he thought the deceased and his friend would, quote 'kick the shit' out of him'," Justice Davis said.

The court heard Mr Saxon would be able to apply for bail while he awaited a retrial.
