The High Court has quashed murder convictions for four South Australian men accused of killing an Albanian refugee in an Adelaide drug house four years ago.
Urim Gjabri was found dead inside a grow house at Para Vista in 2018, with his skull caved in after allegedly being bashed, and his cannabis crop stripped bare.
Benjamin John Mitchell, Alfred Claude Ridney, Matt Bernard Tenhoopen and Aaron Donald Carver were sentenced to life in prison with a non-parole period of 20 years after a jury found the four men guilty of Mr Gjabri's murder.
But after winning their appeal in the nation's highest court, the convictions for the four men have been quashed.
In overturning the convictions, the High Court found the jury in their first trial was not instructed correctly, paving the way for the men's appeals to proceed.
"The focus of these appeals is therefore whether the principle of extended joint criminal enterprise can or should be applied to constructive murder … and whether it was correct for the trial judge to direct that any intentional act of violence would be sufficient," the appeal judgement said.
"The trial judge directed the jury that a conclusion of murder by a primary offender (whomever the person might have been) could extend to any of the accused by extended joint criminal enterprise."
The four men will now face a new Supreme Court trial over the murder.
