Case note: Re X (Inherent Jurisdiction: Vulnerable Adult) [2026] EWHC 2857 (Fam)
In the evening of 22 October 2026, a young mother was due to fly from London Heathrow airport to the Middle East. She was going to stay with her parents, even though she had earlier said her father posed an immediate risk to her safety. Hours before the flight, the out-of-hours High Court judge, Mr Justice Hayden (who fortuitously is well-versed in matters of the inherent jurisdiction), made an urgent order to stop Ms X leaving the country.
At a second hearing a week later, Hayden J looked back at what would have happened otherwise. He said, “Had X boarded the aircraft and returned to her family, I think it likely that she would have been killed”, and noted that Ms X and the police shared that view too.
The background
Ms X is a woman in her late twenties who had lived in Europe with her husband and their young son. She said she had suffered serious abuse from her husband, including financial control, monitoring of her communications, physical violence, strangulation and rape. Those allegations have not been tested. In September 2026 she fled to England, sought advice about divorce and claimed asylum.
In early October, police learned that her husband had allegedly accessed her iCloud account, tracked her devices, found her address and passed it to her family. Threats of serious violence and death followed if she refused to return to the marriage. One person reported that her husband and father had discussed travelling to the UK to kill her for dishonouring the family. Police assessed the case as high risk for both domestic abuse and so-called “honour-based abuse”. Ms X herself put the chance of suffering serious injury in the future at “10 out of 10”. When police took DNA samples so that her body could be identified if the threats were carried out, the detective was struck by how flat and detached she seemed.
Then, in late October, her position changed completely. After renewed contact with her husband, she said she wanted to reconcile and be reunited with her son. She told police she was going to the Middle East voluntarily and trusted her family to protect her. She said “I have to go” , that she needed to “prove” she had not lied, and that she had to “put things right”. Notably, she never withdrew her allegations of abuse.
The legal problem: she had capacity
Ms X had capacity, so the Mental Capacity Act 2005 did not apply, and no application could be made to the Court of Protection. The police argued that her “capacity to assert her own autonomy, even in the face of a real risk to her life, has been squashed by coercion, undue influence and other external pressures”. They asked the High Court to use its inherent jurisdiction to protect this vulnerable adult.
How the court saved Ms X’s life
Here are six interesting aspects of the case, illustrating how the inherent jurisdiction remains a dynamic and life-saving jurisdiction.
1. The court acted fast, out of hours
The application was made by telephone to the out-of-hours judge because Ms X was booked on a flight that same evening. The court granted the order the same day. The next day, the judge was told that police had intercepted X at the boarding gate, served the order and taken her passport.
2. The order was narrow and short-term
The police asked only for a short, tightly focused injunction stopping her from leaving England and Wales, with passport and travel restrictions for a limited period. The aim was not to force her into any particular choice. It was, in the detective's words, to “give her some breathing space”. As the judge put it, the order was meant to support her decision-making, not take it away from her.
3. The court looked past her stated wishes to the reality behind them
The judge did not treat her sudden change of mind as undermining her earlier accounts, noting that victims of this kind of abuse often doubt their own perceptions and give way to others. He also said that respect for autonomy “cannot require the Court to avert its gaze” from evidence that someone's apparent choices are the product of coercion.
The law protects autonomy, not wisdom. Its concern is not with bad decisions but with decisions that are not truly free.
- Mr Justice Hayden
4. The court relied on the right to life
The judge found a real risk to Ms X's safety and her life, which engaged her rights under Article 2 of the European Convention on Human Rights. Article 8 (right to respect for private and family life) was engaged too. He relied on Strasbourg caselaw that say where authorities know or ought to know of a real and immediate risk of serious violence, the State may have to take proactive steps to prevent it. That duty requires the authorities to make their own risk assessment rather than relying only on the victim’s view of the danger.
If there’s a risk that the state thinks it knows better than the individual, the court can step in and suspend influenced decision-making to prevent serious harm.
5. The court took the risk markers seriously
The judge highlighted Ms X’s allegation of non-fatal strangulation, citing research that strangulation increases the risk of homicide eight times. He also accepted the police evidence that victims of honour-based abuse face a much higher risk of homicide than other domestic abuse victims. He agreed that the case presented an exceptionally high level of risk.
To have prioritised X’s overborne and distorted decision-taking under the banner of respect for her autonomy, whilst simultaneously disregarding the grave risks to her life, would have been to abdicate responsibility to a vulnerable woman whose ability to exercise truly independent judgement had been profoundly compromised.
- Mr Justice Hayden
6. The court kept the protection in place
At the return hearing on 29 October 2026, Ms X was represented by counsel. With both parties’ consent, the court extended the order. This means Ms X agreed for her passport to continue to be kept safe by the authorities, and for Interpol to carry out further enquiries. The court noted that police are also looking into the welfare of her son, who (alarmingly) remains with her husband.
From protection to autonomy
The judge was clear that saving Ms X’s life and respecting her autonomy pulled in the same direction. Since the order, Ms X has engaged well with police and support services and has accepted that the likely outcome of her travel would have been death.
The judge said this showed that Ms X “has begun to reclaim her autonomy”. The court's purpose was “to create the space within which she might, freely and authentically, recover it” and “to restore, rather than to restrict, her ability to make her own choices”. Putting her overborne decision-making first under the banner of autonomy, while ignoring the grave risk to her life, would have been “to abdicate responsibility to a vulnerable woman”.
Praise for the police
The judgment praises Devon and Cornwall Police in unusually strong terms. DS Luke Portch had not come across the inherent jurisdiction before, so he researched it himself and arranged for counsel to be instructed for an urgent hearing. Hayden J called the investigation "a paradigm of good practice" and "progressive policing of the very highest calibre". He offered it "as a template for others" and said it should reassure vulnerable women that their voices can be heard.
Why this judgment matters
This case stopping P from travelling is sort of the opposite of the decade-old case of Amina Al-Jeffery v Mohammed Al-Jeffery [2016] EWHC 2151 (Fam). There, P was a dual British-Saudi national who was in Saudi Arabia and wanted to return to the UK but couldn’t because of her very controlling father. The court ordered her father to facilitate and fund her return home, framing the purpose not as forcing any outcome, but as creating the conditions for her to exercise her own free will.
The case of Ms X shows that the inherent jurisdiction can still be used, in a speedy and narrow way, to protect adults who have capacity but whose decisions have been overborne by coercion. Hayden J also reaffirmed that the inherent jurisdiction must be used sparingly. As Maurice Kay LJ said at [12] in Re DL [2012] EWCA Civ 253, it would be “most unfortunate" if such people were “beyond the reach of judicial protection” because of their personal autonomy. Thankfully, Ms X was very much within the reach of judicial protection, and her case shows that the inherent jurisdiction remains an area of the law that saves lives. -
