An unexplained wealth order has effect in spite of any restriction on the disclosure of information (however imposed).
But subsections (1) to (5) of section 361 (rights in connection with privileged information, questions and material) apply in relation to requirements imposed by an unexplained wealth order as they apply in relation to requirements imposed under a disclosure order.
The enforcement authority may take copies of any documents produced by the respondent or any specified responsible officer in connection with complying with the requirements imposed by an unexplained wealth order.
Documents so produced may also be retained for so long as it is necessary to retain them (as opposed to a copy of them) in connection with an investigation of a kind mentioned in section 341 in relation to the property in respect of which the unexplained wealth order is made.
But if the enforcement authority has reasonable grounds to believe that the documents—
they may be retained until the proceedings are concluded.
