Osman v. UK — The Duty to Protect Life (Article 2)

Reviewed by Dr. Anatoliy Yarovyi, Senior Partner — ECHR & Interpol.

Quick answer

In Osman v. the United Kingdom (Grand Chamber, 28 October 1998, application no. 23452/94), the European Court of Human Rights held that there had been no violation of Article 2 (right to life) on the facts, but that there had been a violation of Article 6 § 1 because a blanket immunity shielding the police from negligence claims denied the applicants access to a court. The judgment is best known for the “Osman test” — the standard for when the State has a positive operational duty to protect life.

Background and facts

A schoolteacher, Paul Paget-Lewis, developed a disturbing attachment to one of his pupils, Ahmet Osman. Over a period of time his behaviour escalated: he was linked to a campaign of harassment against the Osman family, including following the boy, spreading rumours, acts of vandalism and a series of incidents that were reported to the police. Eventually Paget-Lewis shot and killed Ahmet’s father, Ali Osman, and seriously wounded Ahmet, and also shot and injured the deputy headmaster and his son.

The family brought a negligence action against the police for failing to protect them despite the warning signs. The domestic courts struck out the claim on the basis of the public-policy immunity that then protected the police from negligence liability in the investigation and suppression of crime. The family complained to Strasbourg under Articles 2, 8, 6 and 13.

The complaint

Article 2 — that the police had failed in their positive duty to protect the lives of the Osman family;
Article 8 — failure to protect their physical integrity and home;
Article 6 § 1 — that the police immunity denied them access to a court; and
Article 13 — lack of an effective remedy.

The Court’s reasoning

The positive duty to protect life — the “Osman test”

The Court confirmed that Article 2 may require the authorities to take preventive operational measures to protect an individual whose life is at risk from the criminal acts of another. But that obligation must be interpreted in a way that does not impose an impossible or disproportionate burden. A breach arises only where the authorities knew or ought to have known at the time of the existence of a real and immediate risk to the life of an identified individual from the criminal acts of a third party, and failed to take measures within the scope of their powers which, judged reasonably, might have been expected to avoid that risk. Applying that test, the Court held that it could not be said that the police knew or ought to have known, at a decisive moment, of a real and immediate risk to the lives of the Osman family; there was therefore no violation of Article 2 (and none under Article 8).

Article 6 and the police immunity

On Article 6 § 1, the Court held that the applicants had an arguable claim in negligence and thus a “civil right”, so Article 6 applied. The domestic courts had applied an exclusionary rule that gave the police a blanket immunity from negligence claims in this field, without weighing the competing public-interest considerations of the individual case. The Court found that this amounted to a disproportionate restriction on the applicants’ right of access to a court, and so violated Article 6 § 1.

The judgment

by seventeen votes to three, no violation of Article 2;
by seventeen votes to three, no violation of Article 8;
unanimously, that Article 6 § 1 applied and had been violated;
by nineteen votes to one, that it was unnecessary to examine the complaint under Article 13; and
an award of £10,000 to each applicant.

Why this case matters

The Osman test. It remains the governing standard for the positive operational duty to protect life, applied in cases on domestic violence, threats, detention and beyond.
Access to court and immunities. Blanket immunities that bar claims without any balancing may breach Article 6 § 1.
A point later revisited. In Z and Others v. the United Kingdom (2001) the Grand Chamber revised its analysis of the Article 6 immunity point, treating the issue as one of the substantive scope of domestic law rather than a procedural bar — but the Osman test on the duty to protect life endures.

What this means for applicants

Article 2 can require the police to act to protect a person from a known, real and immediate threat — but the threshold is demanding.
Evidence of what the authorities knew and when is critical to an Osman-type claim.
Barriers to suing the State may themselves be challenged under Article 6, though the analysis has since been refined.

Frequently Asked Questions

What did Osman v. UK decide?

The Court held there was no violation of Article 2 on the facts, but a violation of Article 6 § 1 because a blanket police immunity denied the applicants access to a court. It set out the “Osman test” for the State’s positive duty to protect life.

What is the Osman test?

A State breaches its positive duty under Article 2 where the authorities knew or ought to have known of a real and immediate risk to the life of an identified individual from a third party, and failed to take reasonable measures within their powers to avoid that risk.

Why was there no violation of Article 2 here?

Because the Court found it could not be said that the police knew or ought to have known, at a decisive time, of a real and immediate risk to the lives of the Osman family.

Is the Article 6 ruling still good law?

The reasoning on the police immunity was revised by the Grand Chamber in Z and Others v. the United Kingdom (2001), but the Osman test on the duty to protect life remains the leading authority.
