Public Order in UK Law

But, as O'Kelly v Harvey shows, where it is necessary in order to prevent a breach of the peace, at common law police officers can take action (in that case dispersing a meeting) which affects people who are not themselves going to be actively involved in the breach.

I would hold therefore that there is room, even in the case of fundamental rights as to whose application no restriction or limitation is permitted by the Convention, for a pragmatic approach to be taken which takes full account of all the circumstances. No reference is made in article 5 to the interests of public safety or the protection of public order as one of the cases in which a person may be deprived of his liberty.

The police are under a duty to keep the peace when a riot is threatened, and to take reasonable steps to prevent serious public disorder, especially if it involves violence to individuals and property. Any sensible person living in a modern democracy would reasonably expect to be confined, or at least accept that it was proper that she could be confined, within a limited space by the police, in some circumstances.

There is a breach of the peace whenever a person who is lawfully carrying out his work is unlawfully and physically prevented by another from doing it. He is entitled by law peacefully to go on with his work on his lawful occasions. If anyone unlawfully and physically obstructs the worker—by lying down or chaining himself to a rig or the like—he is guilty of a breach of the peace.

No doubt there is an absolute and unconditional obligation binding the police authorities to take all steps which appear to them to be necessary for keeping the peace, for preventing crime, or for protecting property from criminal injury; and the public, who pay for this protection through the rates and taxes, cannot lawfully be called upon to make a further payment for that which is their right.

Instances are the lending of constables on the occasions of large gatherings in and outside private premises, as on the occasions of weddings, athletic or boxing contests or race meetings, and the provision of constables at large railway stations.

Prima facie, in a public location the provision of police services in both situations is likely to be in discharge of the duty to maintain law and order.
