"(c) The suspected offence is one under section 4 of this Act and the constable making the requirement has been advised by a medical practitioner that the condition of the person required to provide the specimen might be due to some drug;"
"We were of the opinion that: a) The purpose of the statute in directing a requirement for a medical examination of the Appellant prior a request for blood or urine is to ascertain whether there is any medical condition which would explain the Appellant's behaviour at the time when he was arrested. b) The Police Surgeon made an assessment of the Appellant's general condition as he presented himself before her and found no medical issues at that point in time. c) The Police Surgeon was aware of the results of the Preliminary Impairment test and whilst the Appellant may not have exhibited the same behaviour at the time of the medical examination, she was entitled to form the opinion that the Appellant's failure on the Preliminary Impairment Test might be due to some drug. d) The form MG DD/B was correctly followed in this case."
"At no time after the doctor came to the police station, either on the first or the second occasion according to the evidence before the justices, did the doctor say a single word to the constable as to his view that the condition of the defendant on either occasion was either due to drugs or was due to epilepsy. When Section 83(c) was enacted, I have not the slightest doubt that Parliament intended that there should be a clear indication from a doctor to a police officer at a police station, in circumstances such as this, of the doctor's view as to the possible cause of a defendant's condition as found by him at the police station. By a ‘clear indication’ I mean a clear oral statement by the doctor to the police officer of his opinion. Here obviously there was none."
