A coroner will consider whether failings by police and hospital staff contributed to the death of a Hounslow student.
Jagdip Randhawa, of Cranford , died in October 2011 after being punched during a night out in Leeds by semi-professional boxer Clifton Ty Mitchell.
Mitchell, then 21, of Derby, was jailed for seven years in 2012 after being convicted of the 19-year-old's manslaughter.
It is now known - according to the campaign group Liberty, which is representing Mr Randhawa's family - that Mitchell was on bail at the time of the attack for another serious assault and had breached the conditions on several occasions before that night.
Concerns have also been raised about the standard of care he received at Leeds General Infirmary.
He was placed on a faulty ventilator , starving him of oxygen for 46 minutes, Liberty has said, and it has been suggested staff may have turned the alarms and indicators off meaning the fault was not identified sooner.
One expert described the care Mr Randhawa received as "appalling", claiming it was the worst case of medical negligence he had ever seen, according to Liberty.
Assistant coroner Kevin McLoughlin this week ruled the case engages Article 2 of the Human Rights Act, concerning the "right to life", following representations from Liberty.
That means the forthcoming inquest at Wakefield Coroner's Court will investigate not only how Mr Randhawa died but wider questions around the systems in place and the role of the hospital and police.
'Hopefully... no other family will have to endure this ongoing ordeal'
Jagdip's sister Manjinder Randhawa said: "We have been trying for years to find out the full circumstances around Jagdip's death.
"We still don't understand how the hospital and the police could have ignored the alarm signals – be they from the medical equipment or the offender's repeated breaches of bail.
"Thanks to the Human Rights Act we will finally be able to find out what happened. Hopefully the Article 2 inquest will mean the hospital and the police will learn lessons and no other family will have to endure this ongoing ordeal."
The date for the inquest has been set as August 22 2016.
Mr Randhawa was a former head boy at Cranford Community College and a promising American Football Player. He was in his second year studying English at Leeds University when he died.
An annual memorial football tournament has been set up his friends, with around 25 teams taking to the pitch at his old school last August.
