New Jersey Statutes Title 2C. The New Jersey Code of Criminal Justice 2C § 35B-12

a. Proof of liability in an action brought under this act shall be shown by clear and convincing evidence.

b. A person against whom recovery is sought who has been convicted of a violation of N.J.S.2C:35-5, Manufacturing, Distributing or Dispensing, or an equivalent offense under federal law or the law of any other state, is estopped from denying illegal participation in the market for controlled dangerous substances. If such conviction was based upon the same type of controlled dangerous substance as that used by the individual user, the conviction also constitutes prima facie evidence of the person's participation in the marketing of controlled dangerous substance user pursuant to this act.

c. The absence of a criminal conviction for a violation of N.J.S.2C:35-5 or an equivalent offense under federal law or the law of any other state does not bar recovery by a plaintiff bringing suit pursuant to subsection b. of section 5 of this act.
