Regina v Skegness Magistrates’ Court ex parte Cardy: 1985

Representations that the Intoximeter or other device used for measuring breath alcohol, should not have been approved or that the Secretary of State should have withdrawn approval in respect of the device should be addressed to the Secretary of State and not to the court. While an approval subsisted it is ‘wholly immaterial to mount a challenge to the general reliability of these approved devices in individual prosecutions brought under the Act’. There is no provision for discovery of documents for a summary trial in a magistrates’ court and section 97(1) should not be used as a disguised attempt to obtain discovery. The summons issued to compel the manufacturer to produce documents relating to the functioning and design of the breath-testing instrument was quashed as a ‘fishing expedition’ and because the documents were not admissible per se because they would need an expert witness to interpret them.
