The scales of justice on a plain background

Fox v Chief Constable of Gwent

1986 · AC 281

Posted By lanbuk.com

Facts
Police stopped a driver and required a breath test. The arrest that followed was unlawful. They nevertheless obtained a specimen of breath. The driver said the specimen was the product of the unlawful arrest and should be excluded.
Issue
Does an unlawful arrest make a later breath specimen inadmissible?
Held
No. The House of Lords held that the specimen was admissible. The officers had acted in good faith, under a mistake as to their powers. The illegality of the arrest did not infect the specimen.
Principle
A mistake about a police power is not a reason to exclude real evidence obtained afterwards.
Why it matters
Read it with Jeffrey v Black. Apicella is the case of a sample taken without real consent. Payne is the one exclusion, and it turned on a promise, not on the illegality as such.
