Legal Case Summary
Bird v. Jones [1845] 7 QB 742
False imprisonment – obstruction of a public road
Facts
Bird, B, wished to cross a section of a public road which was closed off due to a boat race. Two policemen, D, prevented B from passing in the direction he wished to go, but was allowed to go in the only other direction in which he could pass. B refused to go in that direction and stood in the same place. B raised an action against D for false imprisonment.
Issues
B claimed that the exclusion from using a section of the public road which prohibited him from moving in one direction, despite all other directions remaining unobstructed, constituted false imprisonment.
Decision/Outcome
Partial obstruction and disturbance does not constitute imprisonment. Coleridge J. stated at paragraph 744 of his judgement that:
“a prison may have its boundary large or narrow, visible and tangible, or, though real, still in the conception only; it may itself be moveable or fixed: but a boundary it must have; and that boundary the party imprisoned must be prevented from passing; he must be prevented from leaving that place, within the ambit of which the party imprisoning would confine him, except by prison-breach.”
A prison must therefore have a boundary. As there was still one direction which B could take, he could not be said to have been imprisoned as he was not confined and prevented from passing or leaving that place. B was at liberty to move off in another direction and no restraint or actual force was used against him.

This case summary remains legally accurate. Bird v Jones (1845) 7 QB 742 continues to be recognised as a leading authority on the tort of false imprisonment, specifically the requirement that there must be a complete restraint of the claimant’s freedom of movement. The principle that partial obstruction — where the claimant retains the ability to move freely in at least one direction — does not constitute false imprisonment remains good law and is still cited in contemporary tort law texts and cases. No statutory or judicial developments have altered this foundational principle. The summary correctly identifies Coleridge J’s often-quoted passage on the necessity of a boundary. Readers should note that modern false imprisonment cases have further developed the surrounding principles (for example, regarding unlawful detention by police and the relevance of the claimant’s awareness of confinement), but these developments do not affect the core ratio of Bird v Jones as described here.
