R (Gillan) v Commissioner of Police of the Metropolis [2006] UKHL 12 2006 2 ac 307
Facts
D authorised the police to carry out a stop and search method on members of the public under section 44 and 45 of the Terrorism Act 2000. The Secretary of State confirmed this authorisation. Cs, a student and a journalist, were stopped and searched by the police in East London during which the police failed to find anything. Cs took legal action against D and the Home Secretary through judicial review of their treatment, the authorisation of the stop and search regime as well as the confirmation.
Legal Issue
Whether the statutory stop-and-search regime and its exercise at the arms fair were lawful and compatible with Convention rights under the domestic law then considered.
Held
The House of Lords dismissed the domestic appeals and upheld the authorisation and confirmation of stop-and-search powers under the Terrorism Act 2000. It considered the statutory provisions sufficiently specific and accepted the safeguards as meeting the Convention objections presented. Lord Bingham discussed the requirement that official interference be governed by clear, accessible rules and protected from arbitrary use. The case’s historical outcome must not be presented without its later qualification. In Gillan and Quinton v United Kingdom, the European Court of Human Rights found an Article 8 violation because the powers lacked adequate constraints against arbitrariness. The old statutory scheme was subsequently altered, so current policing problems require the later framework.
⭐ Legal Principle
The 2006 domestic Gillan decision upheld the then stop-and-search regime, but Strasbourg later found its safeguards insufficient under Article 8 in Gillan and Quinton. The litigation illustrates the need for legal powers to constrain arbitrary interference; the old domestic outcome is not an unqualified current rule.
Significance
Gillan’s domestic decision must be taught together with Gillan and Quinton v United Kingdom, where Strasbourg subsequently found the suspicionless powers insufficiently constrained under Article 8. The statutory framework was later changed. The 2006 judgment is therefore a historical stage in the development of stop-and-search safeguards, not a reliable statement that the old powers remain Convention-compliant. It also illustrates why formal statutory authorisation and the Convention’s quality-of-law requirement are separate inquiries. Rules must constrain arbitrariness, not merely exist on paper.
Common exam questions about this case
Why did the domestic challenge fail in 2006?
The House of Lords accepted the statutory authorisation and safeguards as sufficient for the powers and searches challenged. It rejected the argument that the authority and confirmation were unlawful on the grounds advanced. That conclusion belongs to the domestic judgment at that time and must not be detached from the later Strasbourg ruling.
What did Strasbourg subsequently decide?
Gillan and Quinton v United Kingdom found an Article 8 violation because the discretion was not sufficiently constrained against arbitrary use. The legal framework lacked adequate safeguards. This later decision is essential before describing the old suspicionless stop-and-search regime as compatible with the Convention.
Is an express statutory power enough to satisfy the quality-of-law requirement?
Not necessarily. The Convention also requires accessibility, foreseeability and adequate safeguards against arbitrary interference. A power can be clearly written yet leave excessive uncontrolled discretion in practice. The Gillan litigation is useful precisely because it exposes the difference between legislative authorisation and sufficient protection against arbitrary use.
