Jess Phillips Urges Supreme Court to Overturn Domestic Abuse Ruling 2026

Jess Phillips, the Labour MP and former minister for safeguarding and violence against women and girls, has said she hopes the UK’s highest court “sees sense” and overturns a ruling that prevents a domestic abuse survivor from suing Sussex police and the Crown Prosecution Service (CPS) for disclosing her address to her violent ex-partner. The Supreme Court is due to hear the case on Wednesday and Thursday.

The case, which could have wide implications for police accountability, centers on whether a woman anonymised as XGY can pursue legal action after her address was revealed to a former partner who had been accused of raping her and threatening to kill and throw acid on her. Phillips argues that upholding the earlier court of appeal decision would effectively shield police from accountability in cases involving violence against women and girls.

The background: how the address was disclosed

The disclosure occurred during a magistrates hearing where the CPS sought a condition to prevent XGY’s ex-partner from entering the road where she lived. A CPS lawyer revealed her address, and Sussex police had not marked it as confidential when sending the information to the CPS. As a result of the disclosure, XGY was forced to move home.

The woman sought to sue both Sussex police and the CPS for the breach, but the court of appeal ruled last year that she could not, citing the doctrine of “core immunity.” This legal principle traditionally protects witnesses and lawyers from being sued for what they say in court, but the court of appeal extended it to cover a broader range of police activity, including matters outside the courtroom relating to an investigation.

What the Supreme Court will decide

The Supreme Court will consider whether the court of appeal was correct to apply core immunity so broadly. If the ruling stands, it could make it significantly harder to hold police and prosecutors accountable when they mishandle sensitive information, particularly in cases involving domestic abuse.

Phillips’s intervention highlights the political sensitivity of the case. As a former minister with responsibility for safeguarding, she has been a vocal advocate for victims of domestic abuse. Her comments suggest that the outcome will be closely watched by campaigners and policymakers alike.

Why this ruling matters for victims and accountability

At stake is the ability of victims to seek redress when authorities fail to protect their safety. The case raises fundamental questions about the balance between protecting the integrity of the justice system and ensuring that public bodies can be held to account for negligence.

If the Supreme Court upholds the court of appeal’s decision, it could set a precedent that limits the circumstances under which police and the CPS can be sued for data breaches or other failures. This could have a chilling effect on victims’ willingness to come forward, as they may fear that their personal information could be exposed without consequence.

• Core immunity traditionally protects statements made in court, but the court of appeal extended it to police activities outside the courtroom.
• Jess Phillips argues that upholding the ruling would prevent accountability in violence against women and girls cases.
• XGY had to move home after her address was disclosed to her violent ex-partner.
• The Supreme Court will hear the case on Wednesday and Thursday, with a decision expected later.
• Potential impact: The ruling could affect how police and the CPS handle sensitive information in domestic abuse cases.

Key legal concepts explained

Core immunity is a long-standing legal principle that prevents witnesses, lawyers, and others involved in court proceedings from being sued for what they say in court. It is designed to encourage frank testimony without fear of reprisal. However, the court of appeal’s decision extended this immunity to cover police activities outside the courtroom, such as sending information to the CPS during an investigation.

Critics argue that this extension goes too far and creates a loophole that allows authorities to escape liability for serious errors. The Supreme Court will need to decide whether the court of appeal struck the right balance.

What to watch for next

The Supreme Court’s ruling will have significant implications for police accountability and victim safety. A decision in favor of XGY could open the door for other victims to sue when their personal information is mishandled. Conversely, a ruling against her could entrench the broad interpretation of core immunity.

Phillips’s comments also reflect broader political tensions. The Labour Party has pledged to tackle violence against women and girls, and this case could become a test of that commitment. The government may face pressure to legislate if the courts do not provide clarity. The background to this story is set out in Domestic Abuse History Common Among Henry Nowak Protest.

The case also intersects with ongoing debates about police reform and the handling of domestic abuse cases. In recent years, several high-profile failures have eroded trust in the police’s ability to protect victims. This ruling could further complicate efforts to rebuild that trust.

As the Supreme Court considers the arguments, the eyes of campaigners, legal experts, and victims will be fixed on the outcome. The decision will not only affect XGY but could set a precedent for countless others in similar situations.

A companion piece, Pregnant Women Domestic Abuse Disclosures in England Maternity, approaches the same subject from another angle.

The political ramifications are already evident. Phillips’s remarks have reignited discussions about the Labour Party’s stance on law and order, particularly as Keir Starmer faces internal pressures. The case could become a flashpoint in the broader debate over how the party balances civil liberties with public safety.

Legal experts suggest that the Supreme Court’s decision may hinge on the precise wording of the court of appeal’s judgment and whether it properly applied the principles of core immunity. A ruling is expected in the coming months, and its impact will be felt far beyond this single case.

For those following the intersection of politics and justice, this case is a reminder of the high stakes involved in legal interpretations. As the Supreme Court deliberates, the hope among campaigners is that the law will evolve to better protect the vulnerable and hold power to account.
