Artikel 18

1. Each Party shall adopt such legislative or other measures as may be necessary to ensure that legal persons can be held liable for offences referred to in Articles 15 to 17 of this Convention, committed for their benefit by any natural person, acting either individually or as a member of an organ of the legal person, who has a leading position within the legal person, based on:
a) a power of representation of the legal person;
b) the authority to take decisions on behalf of the legal person;
c) the authority to exercise control within the legal person.
2. Subject to the legal principles of the Party, the liability of a legal person may be criminal, civil or administrative.
3. Other than in the cases already provided for in paragraph 1, each Party shall take the necessary measures to ensure that a legal person can be held liable when lack of supervision or control by a natural person referred to in paragraph 1 has made possible the commission of an offence referred to in Articles 15 to 17 of this Convention for the benefit of that legal person by a natural person acting under its authority.
4. Such liability shall be without prejudice to the criminal liability of the natural persons who have committed the offence.
