Judgment (16 paragraphs)
The applicant was convicted at the Central Court of Petty Sessions, Sydney of driving a motor vehicle upon a public street whilst there was present in his blood the prescribed concentration of alcohol in contravention of s. 4E (1) of the Motor Traffic Act, 1909-1968 N.S.W. (the Act). He appealed to a Court of Quarter Sessions against this conviction. After evidence had been taken in the appeal, a case was stated for the opinion of the Court of Criminal Appeal. The salient facts of that case were that the applicant having been involved in an accident with his car was required by a constable of police to submit to what was described as "an alco test". This was achieved by the applicant breathing into a tube attached to a bag which had been contained in a green plastic box marked "Alco Test R. 80". It was described by the constable as "the approved device". The result of the test was regarded by the constable as unfavourable to the applicant in relation to the alcohol content of his blood whereupon he was arrested. A police sergeant of the Breath Analysis Section thereupon subjected him to a breath analysis test. The time when the applicant was so subjected to breath analysis was within two hours of his having driven his car. According to the certificate to which I shall refer the breath analysis test showed that the applicant's blood contained more than the prescribed concentration of alcohol specified under the Act.
