Gibson’s partner, Marlene Walsh, made the application on behalf of her children asking the High Court for an order to allow the estate to participate and defend the case with the help of legal aid.
It is understood that the CAB case centres on cash in two accounts and an Audi car.
A man is currently before the courts in connection with the killing of Gibson, who was shot dead in 2017 outside an Eddie Rockets at Citywest in west Dublin. Gibson’s pal Darragh Nugent (36) was shot dead days after his the attack at Citywest.
At the time of the shooting Gibson was in a relationship with Marlene, whose brother is under-threat gangland figure James ‘Nellie’ Walsh.
He has been at war with associates of the Kinahan organisation for years since the murder of Jason ‘Jay’ Carroll (39), a friend of Daniel Kinahan.
Carroll was shot in the face and twice in the arm at his home in Cherrywood Drive in Clondalkin in August 2013.
In revenge, his associates planned to murder five men seen as rivals on the same night and at the same time but the plan was cancelled. As the feud heated up a major Garda plan was put in place which involved members of the Criminal Assets Bureau raiding a number of properties and targeting individuals linked to both sides of the divide.
More than €1.2 million in cash, jewellery and cars was seized during searches.
It is understood that the case against the late John Gibson was tied up in those raids and the seizures made then.
His former partner, Marlene made the request for representation on behalf of the estate of John Gibson earlier this week when the CAB’s monthly list was heard virtually through the courts service.
Justice Alexander Owens made the order which will allow the estate apply for free legal aid in order to defend the case. Gibson was the father of a girl and a boy who were five and six at the time of his killing.
James ‘Nellie’ Walsh is serving a ten-year term for a botched hit on gangster ‘Fat Freddie’ Thompson’s former pal, Michael Frazer during which he shot himself in the leg while trying to flee.
Before he was locked up, Walsh had become one of the dominant drug dealers in the Clondalkin area, leading to clashes with the Kinahan- allied outfit.
A plot was hatched to kill Walsh but this went wrong in August 2013 when 21-year-old Dean Johnson was shot dead. It is understood that DNA links dead hitman Glen Clarke to the shooting.
Johnson was totally innocent and it emerged that he had earlier swapped coats with Walsh at a nearby bar and the hitmen mistook him for the criminal.
Last year, Walsh was given an additional two months behind bars when he was caught charging a miniature mobile phone in his cell. He has 65 criminal convictions.
