H418/03 - Article 11: freedom of assembly

Assembly and association

Article 11 protects peaceful assembly and association with others, including forming and joining trade unions to protect one's interests.

An assembly is a gathering of people for a common purpose, such as a demonstration, march or meeting. Association concerns organising with others on a more continuing basis, such as a campaign group or trade union. Article 11 therefore protects more than walking through a street with a placard. Collective action gives people whose individual voices are weak a way to participate in public life.

The assembly protection concerns peaceful conduct. Violence is materially different from forceful or unpopular criticism. Some disruption is an ordinary consequence of gathering in public; it does not automatically put the gathering outside Article 11. Equally, being peaceful does not give an unlimited right to block a road, occupy any chosen land or disregard legal conditions. A failure to follow a domestic procedure does not alone mean the conduct ceases to engage the Convention right; justification of enforcement still matters.

Identify the particular person's behaviour. If a few participants commit violence, that does not automatically remove the rights of an otherwise peaceful participant who neither intends nor participates in it. The authorities must examine the relevant facts rather than treat a crowd as one undifferentiated actor. A counterdemonstration can also engage Article 11, but violent opponents cannot acquire a right to silence the original peaceful gathering.

Article 10 and Article 11 often operate together: a march is collective assembly through which people communicate a message. A single speaker's expression can engage Article 10 without a gathering. For Article 11, explain both the collective conduct and its peaceful nature instead of relying only on the content of a slogan.

Restrictions and positive duties

Article 11 requires both justification for state interference and reasonable steps to make peaceful assembly effective.

Article 11(2) allows restrictions prescribed by law and necessary in a democratic society for a listed aim: national security, public safety, prevention of disorder or crime, protection of health or morals, or protection of others' rights and freedoms. Unlike Article 10, it does not list territorial integrity or judicial authority as separate aims. It expressly permits lawful restrictions on members of the armed forces, police or state administration, rather than removing all their rights without scrutiny.

The legal rule must be sufficiently accessible and foreseeable and the response must be proportionate. Consider the actual harm, how the restriction addresses it, narrower effective options, and the burden on collective expression. A brief route adjustment around an emergency entrance is different from cancelling every march in a town for months. Disagreement with the protesters' politics does not establish a listed aim.

The state also has positive obligations. In Plattform “Ärzte für das Leben” v Austria (1988), opponents disrupted demonstrations. The European Court explained that effective assembly can require reasonable and appropriate protective measures; the state cannot simply refrain from interference and leave peaceful demonstrators unprotected. The obligation is about reasonable measures, not guaranteed success. On the facts, the authorities had taken reasonable and appropriate protective steps. The lesson is not that every disrupted march proves a violation.

Original example: a group announces a peaceful rally and police know a hostile group plans to attack it. Protection and separation of the groups may allow both sides to express lawful views. Cancelling the first rally solely because opponents threaten violence can reward intimidation. If reliable evidence shows that serious violence cannot be prevented through workable alternatives, a carefully limited restriction may nevertheless be justified. Explain the evidence and alternatives before choosing a conclusion.

Statutory protest controls

The Public Order Act 1986 regulates processions and public assemblies through different powers and thresholds.

A procession moves along a route. Under section 11, organisers of specified public processions, including demonstrations and campaigns, generally give written notice of date, start time, route and organiser details at least six clear days ahead. Where that is not reasonably practicable, notice is given as soon as practicable; customary processions and normal funeral processions have exceptions. This is notice, not a general requirement to obtain police permission for every gathering.

Under section 12, a senior police officer may impose necessary conditions on a procession where the statutory reasonable-belief threshold is met. Established grounds include serious public disorder, serious property damage, serious disruption to community life, and an organisers' purpose of intimidation to compel others to act against their rights. Since June 2022, specified noise grounds can also apply in England and Wales. Noise must meet the statutory disruption or significant-impact tests; mere audibility is insufficient. Route conditions can preserve access while allowing the demonstration.

Section 14 supplies a corresponding conditions power for a public assembly. In England and Wales the section 16 definition generally concerns two or more people in a public place wholly or partly open to the air, with specified railway places also covered. Section 14 is no longer limited in England and Wales to conditions about location, numbers and duration: the 2022 amendments allow necessary conditions more broadly. A statutory power must still be exercised compatibly with Articles 10 and 11.
