Four men have been jailed over the manslaughter of Adelaide teenager Christopher Hatzis outside a city nightclub in 2012.

Christopher Hatzis, 19, was ejected from nightclub and was fatally stabbed from a brawl that followed.

Two of the four men, Rrok Jakaj, 20, and Dario Stakaj, 21, held Mr Hatzis down while David Zefi, 23, repeatedly stabbed the victim with a knife.

Judge Ann Vanstone said the horrific loss of life will forever stay with the Hatzis family, and for those who tried to save his life the night of the attack.

In sentencing, Judge Vanstone hoped to set an example and deter others from such crimes.

“It was a futile but tragic altercation between young men who showed a complete lack of judgement, discipline and forbearance,” she said.

“The consequences of the spur of the moment decision … will stay with you forever.

“It was not a planned event. This was a confrontation which developed into a fight and which escalated because of the introduction of a knife.”

Zefi received the longest jail sentence of eight years with a six year and 10 month non-parole period set.

Stakaj received four years with a three year and five month non parole period and Jakaj five years and six months, but can be paroled in four years.

The other offender, a youth at the time of the crime but now 19, got the shortest sentence, three years, that will be served at a youth detention centre.
