The murder charges against seven people have been dropped after five of them pleaded guilty to Dale Creighton's manslaughter and their two co-accused pleaded guilty to lesser charges.
The six men and one woman had been on trial at the Central Criminal Court, charged with murdering the 20-year-old at a footbridge in Tallaght in Dublin almost three years ago.
All seven were re-arraigned this morning.
The five men had their manslaughter pleas accepted by the State and their two co-accused had their pleas to lesser charges accepted.
The jury was discharged on what would have been the 15th day of the trial.
Dale Creighton was assaulted on New Year's morning 2014 at the footbridge over the Tallaght bypass between Saint Dominic's Road and Greenhills Road.
The court heard that there had been an allegation that he had stolen a mobile phone.
He died in hospital the following day. The cause of his death was blunt force injury to his head and face.
The seven accused, who are in their 20s and originally from Tallaght, had all pleaded not guilty to murder.
They are 23-year-old Aisling Burke and 28-year-old David Burke, both with a current address at Beechpark, Collinstown, Co Westmeath; Graham Palmer, aged 26, with a current address at Park Avenue, Portarlington, Co Laois; Ross Callery, aged 23, currently of Gortlum Cottages, Brittas, Co Dublin; James Reid, aged 26, currently of Glen Aoibhinn, Gorey, Co Wexford; Jason Beresford, aged 23, with an address at Coill Diarmuida, Ard a' Laoi, Castledermot, Co Kildare; and Gerard Stevens, aged 27, currently of Grosvenor Square, Rathmines in Dublin.
Each accused also initially pleaded not guilty to violent disorder at the footbridge.
However, Jason Beresford later changed his plea and pleaded guilty to the violent disorder charge.
The prosecution had been due to call its final witnesses this morning but when the jury returned to court after the weekend, the prosecutor asked for each accused to be re-arraigned.
Aisling Burke, a mother-of-one, pleaded guilty to violent disorder at the bridge that New Year's morning.
Graham Palmer had the murder charge put to him again. He pleaded not guilty to murder, but guilty to manslaughter.
Father-of-one Ross Callery also pleaded not guilty to murder, but guilty to manslaughter.
David Burke also pleaded not guilty to murder, but guilty to manslaughter.
James Reid was then arraigned on a new count. He was charged with having a knife, which had a blade or which was sharply pointed at the footbridge. He pleaded guilty to its possession.
Gerard Stevens pleaded not guilty to murder but guilty to manslaughter.
Jason Beresford was the final accused to be re-arraigned in front of the jury. He also pleaded not guilty to murdering Mr Creighton, but guilty to manslaughter.
Ms Justice Deirdre Murphy then addressed the jury of six men and six women.
"Each has been re-arraigned," she explained. "Five of the accused have pleaded guilty to manslaughter and that plea has been accepted."
She said their burden had now been lifted and their function was at an end. She told them they were free to go.
Seán Gillane SC, prosecuting, then mentioned that all but David Burke had been on bail, but asked that each would now be remanded in custody.
Brendan Grehan SC applied for bail on behalf of Aisling Burke, while Kieran O'Loughlin SC applied for bail on behalf of Reid.
Michael O'Higgins asked for seven more days of bail for Callery, so the new father could get his affairs in order.
Michael Bowman SC also requested seven days for his client, Gerard Stevens.
The court granted Aisling Burke bail until sentencing and she remanded Stevens and Callery on bail until next Monday, as requested.
She remanded the others in custody and directed probation reports for Palmer, Callery, Stevens, Beresford, Aisling Burke and David Burke.
She also directed a victim impact report. She thanked the legal teams for their assistance in what she said was a difficult case.
"Even at this late stage, the court is pleased that these young people have all acknowledged their involvement," she said, offering her condolences to Mr Creighton's family.
Sentencing will take place in December.
