The family of Yousef Makki must wait to see if there is to be another inquest into his death after an appeal to two High Court judges.
The tragic teen was stabbed in the heart by Joshua Molnar in Hale Barns more than three and a half years ago, in circumstances which an initial inquest said were not ascertainable on the balance of probabilities.
Coroner Alison Mutch ruled out the conclusions of lawful killing or unlawful killing at Stockport Coroner's Court last year as a result.
This came after the trial at Manchester Crown Court, where Mr Molnar was cleared of murder and manslaughter, but convicted of possession of a knife and perverting the course of justice for lying to the police.
However, representatives for Yousef's father Ghaleb Makki and Yousef's sister Jade Akoum suggested there were a number of issues with the approach taken by Ms Mutch.
At the High Court in Manchester on Monday, Pete Weatherby KC addressed Lady Justice Julia Macur and Mr Justice Michael Fordham on these issues, which focused on an alleged failure to consider Mr Molnar's credibility or reliability as a witness, and Mr Molnar's state of mind at the time of the incident.
Mr Weatherby said: "In the case of a young man being stabbed to death in a street, the lawfulness or otherwise is in the public interest.
"The coroner should have determined these issues if possible."
If Lady Justice Macur and Mr Justice Fordham are in agreement, there is to be another inquest into the death.
But Alistair Webster KC, for Mr Molnar, said the outcome of the initial inquest was 'rational' and 'reasonable'.
He said: "[Ms Mutch] adamantly examined all of the evidence and explained her conclusions in a way that was entirely comprehensible."
No judgement was made on Monday, although Lady Justice Macur said one would be made 'as soon as possible'.
She said: "We will not be able to deliver a judgement today. We are very sorry, but it is very important we consider all of these matters."
