490.Section 336 provides that a nominated officer must not give appropriate consent unless he has authorisation from the National Criminal Intelligence Service or the time limits specified in subsections (7) to (9) have expired. These time limits mirror the limits in section 335 for the giving of consent to an otherwise prohibited act by a customs officer or constable. Section 335(5) makes it an offence for a nominated officer to consent to an otherwise prohibited act except as outlined above. A nominated officer does not commit an offence under this section if he gives consent to a transaction taking place, if he genuinely does not know or suspect that money laundering is taking place.
