Article 13 Cooperation with police
A person does not commit an offence under any of articles 6 to 9 if he is acting with the express consent of a constable.
Subject to paragraphs (3) and (4), a person does not commit an offence under any of articles 6 to 9 by involvement in a transaction or arrangement relating to money or other property if he discloses to a constable—
his suspicion or belief that the money or other property is terrorist property, and
the information on which his suspicion or belief is based.
Paragraph (2) applies only where a person makes a disclosure—
after he becomes involved in the transaction or arrangement concerned,
on his own initiative, and
as soon as is reasonably practicable.
Paragraph (2) does not apply to a person if—
a constable forbids him to continue his involvement in the transaction or arrangement to which the disclosure relates, and
he continues his involvement.
It is a defence for a person charged with an offence under any of articles 6(2) and (3) and 7 to 9 to prove that—
he intended to make a disclosure of the kind mentioned in paragraphs (2) and (3), and
there is reasonable excuse for his failure to do so.
Where—
a person is in employment, and
his employer has established a procedure for the making of disclosures of the same kind as may be made to a constable under paragraph (2),
this article shall have effect in relation to that person as if any reference to disclosure to a constable included a reference to disclosure in accordance with the procedure.
A reference in this article to a transaction or arrangement relating to money or other property includes a reference to use or possession.
