Director of Public Prosecutions v John Kay: QBD 4 Mar 1998

The court considered a decision by Justices to exclude evidence under section 8 of the 1984 Act where a police officer had allegedly failed to follow the guidance in relation to a roadside breath test.
Held: The procedure was not required by the Act and sent the case back to the Justices with a direction to admit the constable’s evidence of that test. The failure of a constable to wait until after twenty minutes after driver’s last drink did not invalidate the request for a roadside breath test. The Act is not to be defeated by technicalities.
