In deciding whether or not to grant day leave or overnight leave to a person subject to control, the Secretary must have regard to the following matters--
(a) whether the person would be likely to commit any offence if the person were to be granted leave,
(b) whether the granting of leave would be likely to create a risk to public safety,
(c) whether the person's conduct while detained in a detention centre indicates that the person would observe any conditions to which leave would be subject,
(d) whether the person would be likely to interfere with, or attempt to interfere with, a witness in any proceedings,
(e) any previous history of escape or absconding of the person from lawful custody,
(f) the kind of supervision to which the person would be likely to be subject while on leave,
(g) whether the granting of leave would be likely to bring the person into contact with any victim of the offence in relation to which the person is detained,
(h) any other matter that is, in the opinion of the Secretary, relevant to the decision.
