—(1) No sample of blood shall be taken from a person who is arrested and accused of a crime unless the appropriate consent is given for the taking of the sample.
(2) If the appropriate consent required under subsection (1) for the taking of a sample of blood from a person is refused without good cause or cannot be obtained despite all reasonable efforts, that person may be taken before a Magistrate and the Magistrate may, if satisfied that there is reasonable cause to believe that the sample may confirm or disprove whether that person was involved in committing the crime, order that the person provide the sample required.
(3) Where it is shown that the appropriate consent required under subsection (1) for the taking of a sample of blood from a person was refused without good cause, the court, in determining —
whether to commit that person for trial in connection with the crime of which he is accused of committing;
whether there is a case to answer against that person; or
whether that person is guilty of the crime with which he has been charged,
may draw such inference from the refusal as it thinks proper and, based on such inference, may treat the refusal as corroboration or amounting to corroboration of any relevant evidence against that person.
