This section applies to—
any person named by the Scottish Ministers for the purpose of a civil recovery investigation , a detained cash investigation, a detained property investigation , a frozen funds investigation or a cryptoasset investigation under Part 8, or
any person authorised by the Scottish Ministers for the purpose of such a civil recovery investigation to receive relevant information under section 391,
if it is necessary or expedient for the person to identify himself by name for that purpose.
The Scottish Ministers may direct that such a person may for that purpose identify himself by means of a pseudonym.
For the purposes of any proceedings or application under this Act, a certificate signed by the Scottish Ministers which sufficiently identifies the person by reference to the pseudonym is conclusive evidence that the person is authorised to use the pseudonym.
In any proceedings or application under this Act a person in respect of whom a direction under this section is in force must not be asked (and if asked is not required to answer) any question which is likely to reveal his true identity.
