Commentary on provisions of Act Section 8: Inclusion of non-disclosure requirement in order
This section enables the judge who is making an overseas production order to include a requirement on the person against whom the order is made, not to disclose the existence or contents of the order unless leave is given by a judge (as defined in section 1) or with written permission from the appropriate officer who applied for the order or an equivalent officer.
	When imposing a non-disclosure requirement, subsection (3) requires a judge to specify when that requirement expires (a non-disclosure requirement cannot be open ended).
	At the time of revoking an overseas production order, the judge may order that any unexpired non-disclosure requirement imposed as part of that order is to continue to have effect. This may be appropriate, for example, where it is clear to the judge that a further overseas production order may be sought. Such an order may specify or describe a different time when the non-disclosure requirement is to expire than that specified or described in the overseas production order that is being revoked.
