The High Court has heard that a traumatised young woman who has expressed an intent to kill her mother poses a serious risk to her mother's life.
Concern for the mother's safety has arisen after the court heard there was no medical basis to make the 18-year-old daughter a ward of court.
In order to be made a ward of court, there must be medical evidence that a proposed ward lacks capacity to make decisions about themselves and their finances.
The court heard the matter was taken very seriously by gardaí and state agencies and it was felt the teenager's mother should be re-housed outside her current county.
The president of the High Court, Ms Justice Mary Irvine, said there was nothing more imperative than the safety and life of the mother and she should top any priority list of a council when it comes to rehousing her.
The 18-year-old had opposed an application to make her a ward of court which had been initiated by the Child and Family Agency late last year. At the time, a psychiatric report said she lacked capacity but since then two further reports have shown she has regained capacity.
She is currently in a special care unit, which is not secure.
Psychiatrists say she needs to be placed in a medium secure care unit but all such units approached to date, including in the UK, are unwilling to take her.
She is also the subject of criminal proceedings in the District Court in relation to charges of alleged assault. She was also questioned by gardaí last week in relation to an alleged spitting incident.
There is a prior history of assault and sexual violence in the case and an incident earlier in 2019 led to the woman's admission to special care.
She had described her intentions and a large knife was found, the court heard. She had set out in a manuscript a plan to kill and mutilate someone which, the CFA said, was treated as a "definite" threat.
She also talked about wanting to go to college, reflecting a form of "deep seated disordered thinking".
It was considered she would need to be placed in a UK specialist unit as the level of complexity presented exceeds anything the services here have come across, the CFA said.
The case was adjourned until Monday for the making of final orders which would withdraw the wardship proceedings initiated by the Child and Family Agency.
In light of the withdrawal of the wardship application, efforts will be made to procure her agreement to an appropriate voluntary placement.
Because of the updated psychiatric evidence, the wardship application will not be pursued.
Lawyers for the woman's mother, said she and the gardaí are very concerned for her safety and had agreed she must immediately move from her current residence and county. That is urgent but cooperation from another local authority would be required, they said.
The judge said she could "think of nothing more imperative than the safety and life of the mother" and the matter should go to the top of any priority housing list of the relevant council.
