(1) If several persons participate in a regulatory offence, each of them is deemed to have committed a regulatory offence. This also applies if specific personal characteristics (section 9 (1)) giving rise to the possibility to impose a sanction pertain only to one participant.
(2) Participation may be sanctioned only if the factual elements of an act set forth in a statute enabling imposition of a regulatory fine are unlawfully fulfilled, or if in cases where an attempt may also be sanctioned, the attempt has at least been made.
(3) If one of the participants does not act reprehensibly, this does not mean that sanctioning of the others is precluded. If the statute provides that specific personal characteristics preclude sanctioning, this only applies to a participant who displays such characteristics.
(4) If the statute provides that an act which would otherwise be a regulatory offence is a criminal offence in view of specific personal characteristics of the perpetrator, this only applies to a participant who displays such characteristics.
