Blood tests
13.—(1)  Any officer of the Bureau, police officer, special police officer, or the officer-in-charge of an approved centre may require any person who has used or inhaled, or is reasonably suspected to have used or inhaled, any intoxicating substance for the purpose of inducing or causing a state of intoxication to provide to a registered medical practitioner a specimen of his blood for a laboratory test.
(2)  A person shall not be required to provide a specimen of his blood for a laboratory test under subsection (1) if the registered medical practitioner in immediate charge of his case objects to the provision of such specimen on the ground that it would be prejudicial to the proper care or treatment of that person.
(3)  A person who without reasonable excuse fails to provide a specimen of his blood for a laboratory test in pursuance of a requirement imposed under subsection (1) shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $2,000 or to imprisonment for a term not exceeding 3 months.
(4)  Any officer of the Bureau, police officer or special police officer, or the officer-in-charge of an approved centre shall, on requiring any person under this section to provide a specimen of blood for a laboratory test, warn him that failure to provide a specimen of blood may make him liable to a fine or imprisonment, and, if such officer fails to do so, the court before which the person is charged with an offence under subsection (3) may dismiss the charge.
(5)  For the purposes of any proceedings for an offence under section 3, a certificate purporting to be signed by a registered medical practitioner that he took a specimen of blood from a person with his consent shall be evidence of the matters so certified and of the qualifications of the registered medical practitioner.
(6)  The certificate referred to in subsection (5) shall not be accepted as evidence for the prosecution unless a copy thereof had been served on the accused not less than 7 days before the hearing.
(7)  For the purposes of this section, the consent of a person who has attained the age of 16 years to providing a specimen of blood in pursuance of a requirement imposed under subsection (1) shall be effective as it would be if he were of full age.
(8)  Where the person referred to in subsection (7) has, by virtue of that subsection, given an effective consent, it shall not be necessary to obtain any consent from his parent or guardian in respect of him providing the specimen of blood.
