(b) The organisation is a terrorist organisation; and

(c) The person knows the organisation is a terrorist organisation.

(2) Subsection (1) does not apply if the person proves he or she took all reasonable steps to cease to be a member of the organisation as soon as practicable after the person knew that the organisation was a terrorist organisation
