(1)  If, because of this Act, a court may give any leave, permission or direction, the leave, permission or direction may be given on any terms the court thinks fit.

(2)  Without limiting the matters that the court may take into account in deciding whether to give the leave, permission or direction, it is to take into account –

(a) the extent to which to do so would be likely to add unduly to, or to shorten, the length of the hearing; and

(b) the extent to which to do so would be unfair to a party or to a witness; and

(c) the importance of the evidence in relation to which the leave, permission or direction is sought; and

(d) the nature of the proceeding; and

(e) the power of the court, if any, to adjourn the hearing or to make another order or to give a direction in relation to the evidence.
