"(1) The court shall not make a supervision and treatment order unless it is satisfied- (a) that, having regard to all the circumstances of the case, the making of such an order is the most suitable means of dealing with the accused or appellant; and (b) on the written or oral evidence of two or more registered medical practitioners, at least one of whom is duly approved, that the mental condition of the accused or appellant- (i) is such as requires and may be susceptible to treatment; but (ii) is not such as to warrant the making of an admission order within the meaning of Schedule 1 to this Act, or the making of a guardianship order within the meaning of the 1983 Act. (4) An order for the admission of an offender to a hospital shall not be made under this section unless the court is satisfied on the written or oral evidence of the registerd medical practitioner who would be in charge of his treatment or of some other person representing the managers of the hospital that arrangements have been made for his admission to that hospital ... and for his admission to it within the period of 28 days beginning with the date of the making of such an order; and the court may, pending his admission within that period, give such directions as it thinks fit for his conveyance to and detention in a place of safety. (7) A hospital order or guardianship order shall specify the form or forms of mental disorder referred to in subsection (2)(a) above from which, upon the evidence taken into account under that subsection, the offender is found by the court to be sufering; and no such order shall be made unless the offender is described by each of the practitioners whose evidence is taken into account under that subsection as suffering from the same one of those forms of mental disorder, whether or not he is also described by either of them as suffering from another of them."
