In CLG and others v Chief Constable of Merseyside [2015] EWCA Civ 836 the Court of Appeal considered the case of CLG and his family that arose out of the disclosure of their address to defendants in criminal proceedings that was known – because of threats to their lives – to only members of their close family. Although the family members were not informants, nor had they provided the information in confidence, the judgment provides some insight as to how easily the mishandling of sensitive material can lead to problems.

The family had reported an incident to the police in 2009. An unidentified gunman had fired a bullet through the front door of their house. A prosecution followed of individuals connected with possession of the firearm involved. Press reporting at the conclusion of this case identified the street where the family lived. Following this CLG received a letter referring to him as a “grass” and which included a spent bullet casing.

Some time later CLG and his partner were notified that they were required as prosecution witnesses at the trial of various persons accused of, among other things, firing guns into residential premises, including their former home. They failed to attend the trial following which the police applied for a warrant for their arrest. A witness statement by an officer in support of the application included a reference to the address where the family was now living. This should have been provided to the disclosure officer in usual way prior to it being disclosed to the Crown Prosecution Service. The purpose of doing so was to ensure the disclosure officer considered whether it included any sensitive material that may need to be protected. However, this did not happen and the statement was passed directly to the CPS.

The CPS should have considered the contents of the statement to see whether it contained any sensitive material before deciding what use to make of it. Again, this did not occur and it served the statement, including details of the appellants’ current address, on those representing the defendants under a notice of additional evidence. It was only after CLG and his partner were produced at court it became clear that the secure address had been disclosed. The family was moved to various temporary addresses before eventually finding permanent accommodation. The family sued the Chief Constable for damages for negligence and under the Human Rights Act 1998 and the Data Protection Act 1998. The Chief Constable denied liability on the basis that the CPS alone was responsible for the disclosure of the family’s address. In any event public policy operated to protect him from liability: first, the principle that the police are immune from proceedings based on acts and omissions committed in the course of their core duties of preventing and investigating crime and protecting property; and second, the principle that there is no liability for anything said or done in the course of judicial proceedings.

The trial judge held that the police and the CPS were both at fault, “the police having made what he described as a material contribution to the disclosure, and that they were jointly and severally liable for any breach of duty towards the appellants” but that public policy operated to obviate any duty of care. The judge relied on the line of authority beginning with Hill v West Yorkshire Police [1989] AC 53 and culminating in Michael v Chief Constable of South Wales Police [2015] UKSC 2. Further there was no breach of Article 2 of the Convention the family was not at “real and immediate risk of death or serious physical harm”. The claims under Article 8 and the Data Protection Act were also dismissed. Interestingly, the judge expressed the view that the public policy of witness immunity or immunity for acts done in the course of judicial proceedings would have provided a defence to any of the claims: see Darker v Chief Constable of the West Midlands [2001] 1 AC 435.

On the appeal the first issue the court examined was whether the information provided by the family was in confidence. It held that it was not. The family had provided witness statements and disclosed their addresses. Although it was not clear how the police were aware of the new address the court was satisfied it had not been disclosed in confidence. That said, the police were aware that disclosure of the address could have significant implications for the family’s safety. The next issue for the court therefore was whether in those circumstances the police owed a duty of care to the appellants to take reasonable steps to prevent that from happening.

The three-fold test in Caparo Industries plc v Dickman [1990] 2AC 605 applied. If this case had concerned only a relationship between private persons, it would have been fair just and reasonable to impose a duty of care. However, the police did not owe a private law duty of care to the public in general in carrying out their core functions. The question arising therefore was whether “in making a statement with a view to giving evidence of that fact and producing that statement to the prosecuting authority for the purposes of making an application for a warrant of arrest all form part of their core function of obtaining and preserving evidence, in the discharge of which they do not owe a duty of care to the public at large”. The court of appeal held that it fell within their core functions. So too their general interaction with witnesses, although they may assume a duty of care towards a particular individual if they have had dealings with him of a kind that involve an acceptance of responsibility for their safety.

The court also considered whether the trial judge was correct to indicate that the principle of judicial immunity would not otherwise have applied. The leading authority remained Darker. In that case the House of Lords held that the fabrication of evidence by police officers fell outside of the immunity. The principle has been considered in a number of other cases, including Taylor v Director of the Serious Fraud Office [1999] 2 AC 177 and Singh v Reading Borough Council [2013] EWCA Civ 909. In this latter case Lewison LJ (with whom Maurice Kay and Gloster LJJ) agreed, re-stated the relevant principles as follows:

“(i) The core immunity relates to the giving of evidence and its rationale is to ensure that persons who may be witnesses in other cases in the future will not be deterred from giving evidence by fear of being sued for what they say in court;
(ii) The core immunity also comprises statements of case and other documents placed before the court;
(iii) That immunity is extended only to that which is necessary in order to prevent the core immunity from being outflanked;
(iv) Whether something is necessary is to be decided by reference to what is practically necessary;
(v) Where the gist of the cause of action is not the allegedly false statement itself, but is based on things that would not form part of the evidence in a judicial enquiry, there is no necessity to extend the immunity;
and (vi) In such cases the principle that a wrong should not be without a remedy prevails.”

The principles have been considered again in the recent decision of Daniels v Chief Constable of South Wales Police [2015] EWCA Civ 680. In this case their Lordships held that “the scope of the immunity is limited to statements made by witnesses in the course of giving evidence and to certain limited but necessary extensions of that principle. The fact that an activity may be intimately associated with the judicial phase of the criminal process, as distinct from the administrative or investigatory function, arguably does not, in itself, necessarily give rise to immunity”.

The question for the Court of Appeal in this connection was whether the revelation of the statement by the police to the CPS was inexorably linked to the officer’s preparations to give evidence in support of the application by the prosecution for a warrant of arrest. Their Lordships held that it was as to hold the otherwise would outflank the immunity they were entitled to in relation to the evidence once given in court. The police were immune from action in respect of the revelation of the statement to the CPS notwithstanding it was negligent.

The Article 8 claim was dismissed by the trial judge on the basis, although the right had been interfered with, in that the family had been required to move house as a result of the disclosure, this was a reasonable response to an isolated event and was not as a result of a systemic failure. The court of appeal agreed. The data protection element of the appeal also failed, the court finding that the police were entitled to the exemption of prevention and detection of crime set out in s 29 of the Data Protection Act 1998.

Although the police and CPS can take some comfort from this judgment that public policy will in similar circumstances come to their aid, it highlights a number of underlying concerns. If the information had been provided in confidence or harm had come to the family, it may have been a very different outcome. It should be looked at as a lucky escape rather and an opportunity to learn from a near miss.

The key practical principles arising from the judgment are these:

– Examine the nature of the information provided by witnesses and other sources: if it is confidential onerous duties to maintain the confidentiality of it arise (see in particular R (on the application of WV) v Crown Prosecution Service [2011] EWHC 2480 (Admin))

– Check assiduous adherence to the statutory framework when dealing with disclosure, particularly if it is material that is or might be sensitive – avoid allowing the pressures of trial to dictate a deviation from well-established procedures

– If the source of the information is a Covert Human Intelligence Source, the framework set out in Part II of RIPA 2000 may give rise of a statutory duty of care: An Informer v A Chief Constable [2012] EWCA Civ 197

– “Real and Immediate” in the context of Article 2 is a high threshold to meet and one that is not readily satisfied: Re: Officer L [2007] UKHL 36
