XGY v Sussex Police & Anor

Factual and Procedural Background

The Appellant, a victim of domestic violence by her partner ("K"), reported various assaults and threats to the Police in November 2019. Following the end of the relationship, the Appellant relocated multiple times for safety, initially to an aunt's address in Epsom and later to a confidential address in Liphook, Hampshire, which she expressly requested the Police to keep secret from K. Despite this, the Police disclosed her confidential Hampshire address to the Crown Prosecution Service (CPS) without appropriate confidentiality markings due to a known IT issue. Subsequently, at a Magistrates Court bail hearing, the CPS advocate disclosed the Appellant’s confidential address to K by requesting a bail condition referencing that address, thereby endangering the Appellant and causing her psychiatric harm.

The Appellant brought civil claims against the Police and CPS for breaches of statutory duties under the Human Rights Act 1998 (HRA), the Data Protection Act 2018 (DPA), and common law, seeking damages for psychiatric injury and consequential losses. The Defendants applied to strike out the claims and for summary judgment, asserting various immunities from suit. The lower court struck out the claims related to the Hampshire disclosure and granted summary judgment to the Defendants on the HRA and DPA claims, while allowing claims related to the earlier Epsom disclosure to continue. The Appellant appeals against these rulings.

Legal Issues Presented

1. What is the scope and justification of Witness Immunity before Court (BC) and Legal Proceedings Immunity BC, particularly regarding the Police’s disclosure of the Appellant’s confidential Hampshire address to the CPS?
2. What is the scope and justification of Advocates Immunity at Court (AC), especially concerning the CPS advocate’s disclosure of the Appellant’s confidential address during the bail hearing?
3. Whether the strike out jurisdiction was appropriate to determine the scope and application of the claimed immunities in the context of disputed facts and limited evidence.
4. Whether the summary judgment jurisdiction was correctly applied in dismissing the Appellant’s claims under the HRA and DPA on the limited evidence available.

Arguments of the Parties

Appellant's Arguments

• There is no blanket Advocates Immunity AC; immunity must be justified in each case, especially when it extinguishes valid claims for tort or statutory breaches.
• Witness Immunity AC is the only core immunity; extensions such as Witness Immunity BC and Legal Proceedings Immunity BC require justification and should not cover administrative acts like disclosing confidential information.
• The Police’s disclosure of the Appellant’s confidential address was administrative, extraneous to evidence, and endangered the Appellant, undermining any justification for immunity.
• The CPS advocate’s disclosure of the confidential address in Court was unnecessary, not evidential, and contrary to the public interest in protecting vulnerable witnesses.
• The Appellant’s HRA claims under Articles 2, 3, and 8 were arguable, as the Police and CPS failed to protect her from real and immediate risk and caused psychiatric harm.
• Strike out was inappropriate for deciding complex immunity issues without full disclosure and evidence.

First Defendant/Respondent (Police) Arguments

• The immunities of Witness Immunity (AC and BC) and Advocates Immunity AC are well-established, absolute, and cover all torts and statutory breaches including HRA and DPA claims.
• The Police’s preparation of the CPS file, including passing the Appellant’s address, was covered by Witness Immunity BC or Advocates Immunity BC as part of preparing evidence for Court.
• The purpose of immunity is to protect the Court process and participants, ensuring freedom of speech without fear of civil action.
• The Police denied that the Appellant was a victim under the HRA and asserted no real or immediate risk to her life or well-being existed at the relevant times.
• The Police submitted that no tortious wrong arose until the CPS disclosed the address in Court, and that the claims against the Police were parasitic on those against the CPS.

Second Defendant/Respondent (CPS) Arguments

• The Judge correctly found that Advocates Immunity AC applied to the CPS advocate’s disclosure of the address in Court.
• Only new extensions of immunity require justification; established immunities should not be undermined by factual disputes.
• The disclosure was part of a hearing and could have been challenged as evidence, thus falling within the immunity.
• Immunity covers all types of civil claims, including those under the HRA and DPA.
• The Judge’s factual findings on risk were entitled to deference, and the summary judgment dismissal of the Appellant’s claims was appropriate.

Court's Reasoning and Analysis

The Court undertook a detailed review of the historical and modern case law on immunities, distinguishing between core immunities (Witness Immunity AC, Judges Immunity AC, and Advocates Immunity AC relating to evidence) and extensions such as Witness Immunity BC and Legal Proceedings Immunity BC. It emphasized the legal principle that immunities are exceptions to the fundamental right of access to courts and must be justified by public policy, particularly where they bar claims by vulnerable individuals such as victims of domestic abuse.

The Court found that the Police’s disclosure of the Appellant’s confidential Hampshire address to the CPS was arguably administrative or procedural, not evidential, and therefore arguably fell outside the scope of Witness Immunity BC or Legal Proceedings Immunity BC. The absence of a red flag and the known IT defect undermined the justification for immunity, as the disclosure endangered the Appellant, the very witness the immunity is designed to protect.

Regarding the CPS advocate’s disclosure of the confidential address in Court, the Court acknowledged that Advocates Immunity AC is a well-established core immunity protecting advocates from civil claims relating to conduct in Court. However, the Court held that the immunity is not absolute in all circumstances; it must be justified by public policy considerations. Here, the disclosure was unnecessary, endangered a vulnerable witness, and was described as a "muck up." The Court reasoned that granting immunity in such circumstances would undermine the rationale for Advocates Immunity AC and fail to promote the administration of justice.

The Court also held that the strike out jurisdiction was not appropriate to resolve these complicated and fact-sensitive issues, particularly when disclosure was incomplete and no defence was filed by the CPS. It was preferable that these matters be resolved after full disclosure and evidence.

Finally, the Court found that the summary judgment dismissal of the Appellant’s HRA claims was premature and inappropriate on the limited evidence. The Court noted the absence of critical evidence about the accused’s mental state, criminal history, and reaction to the rape allegation, all relevant to assessing the real and immediate risk to the Appellant’s life and health. The Court emphasized that the Appellant’s psychiatric injury claims and interference with her family life under Article 8 were distinct and merited full consideration.

Holding and Implications

The Court GRANTED permission to appeal on all grounds and ALLOWED the appeal.

The Court quashed the lower court’s order striking out the claims and granting summary judgment to the Defendants. The claims relating to the Police’s disclosure of the confidential Hampshire address and the CPS advocate’s disclosure in Court will proceed for directions and further case management. The Court held that the immunities claimed by the Defendants were not clearly established or justified on the facts as pleaded and that the strike out and summary judgment applications were premature without full disclosure and evidence.

This decision restores the Appellant’s ability to pursue her claims for breaches of statutory and common law duties, including under the HRA and DPA, emphasizing that immunities from suit are not absolute and must be justified in light of the specific facts and public interest. No new precedent was established, but the ruling affirms the modern trend towards careful scrutiny of immunity claims and the protection of vulnerable witnesses’ rights to redress.
