Under sections 79 and 80 of the Money Laundering and Proceeds of Crime Act, property may be forfeited as 'tainted property' where the applicant proves on a balance of probabilities that it is the proceeds of crime or instrumentalities of serious offences, without needing to prove that the property was derived from a particular or specific serious offence or that any person has been charged with such an offence - it is sufficient to show the property was derived from some serious offence. Knowledge, suspicion, intent or purpose required as elements of a money laundering offence may be inferred from objective factual circumstances pursuant to section 8(5) of the MLPCA. Where vehicles have had their identities systematically falsified through alteration of chassis numbers, repainting, and other tampering, and no innocent explanation is established, the court may infer on a balance of probabilities that such falsification indicates the vehicles are connected to some form of criminal activity and thus constitute tainted property subject to forfeiture. Civil forfeiture orders under the MLPCA are made against the property itself (in rem) and do not require proof of criminal conduct by the property owner or possessor, though such conduct may be inferred from the circumstances.
