Director of Public Prosecutions v Armstrong-Braun: Admn 5 Oct 1998

A building site was subject to a requirement to move great crested newts before work could proceed. The defendant, a local councillor interfered to prevent a digger destroying the land until the newts had been moved. He appealed his conviction for assault, saying he had acted lawfully in attempting to prevent a crime.
Held: The test of what is reasonable force for self defence was what was objectively reasonable in the light of the actual subjective belief of the defendant as to the circumstances in which he found himself. Sedley LJ said: ‘while an act done in self defence does not lose the protection of the law because the perceived threat turns out not to have been real, what is done in answer to the perceived threat is to be judged by a judicial appraisal of its reasonableness in all the circumstances which, by definition, include the defendant’s honest belief as to the danger he is in.’
