Dallison v Caffery: CACD 1965

It is for the detaining authority to justify all periods of detention.
The court described the common law duty on a prosecutor to disclose material. Lord Denning MR said: ‘The duty of a prosecuting counsel or solicitor, as I have always understood it, is this: if he knows of a credible witness who can speak to material facts which tend to show the prisoner to be innocent, he must either call that witness himself or make his statement available to the defence. It would be highly reprehensible to conceal from the court the evidence which such a witness can give. If the prosecuting counsel or solicitor knows, not of a credible witness, but a witness whom he does not accept as credible, he should tell the defence about him so that they can call him if they wish. Here the solicitor, immediately after the court proceedings [for committal before the magistrates], gave the solicitor for the defence the statement of Mr. and Mrs. Stamp; and thereby he did his duty.’
Diplock LJ said that it is for the trial judge objectively to determine whether the suspicion held by a police officer and used to justify an arrest was reasonable and that whether there are such grounds or not is a question of law: ‘The test whether there was reasonable and probable cause for the arrest or prosecution is an objective one, namely, whether a reasonable man, assumed to know the law and possessed of the information which in fact was possessed by the defendant, would believe that there was reasonable and probable cause.’
He described the continuing nature of an arrest: ‘The trespass by the arrestor continues so long as he retains custody of the arrested person, and he must justify the continuance of his custody by showing that it was reasonable. What is reasonable conduct on the part of a police officer in this respect may not be the same as what would be reasonable conduct on the part of a private arrestor.’
