Part VI of the Criminal Code is headed "Offences relating to property and contracts", and I have no doubt that the phrase "offences relating to property" in s. 22 should be construed as applying exclusively to offences of the character of those defined in that Part of the Code. These offences can be classified under the headings of wrongful or fraudulent interference with the property of others which involve deprivation of or interference with the proprietary or possessory rights of the true owner or person in possession, or acts involving destruction or damage to the property of others. I consider that such a construction is supported by the provision that the existence of an intent to defraud would deprive a defendant of the benefit of the protection.
The offences that are defined in Pt VI of the Code which might be marshalled under the category of offences relating to property have in common the characteristic that an element of the offence is either the causing of another to part with property or the infringement of another's right over or in respect of property. But does s. 22 apply only to offences which exhibit that characteristic? Or is it sufficient to attract the operation of s. 22 that the relevant act or omission affects in some way a thing which answers the description of "property" in s. 1 - e.g., by destroying, damaging, using, disposing of or otherwise dealing with property or rights over or in respect of property? If s. 22 were to be understood as applying to any act or omission affecting property, it would have an operation far wider than has been attributed to it in Queensland thus far (see Olsen v. Grain Sorghum Marketing Board; Ex parte Olsen [36] ) and far wider than the common law defence from which it was derived. The wider interpretation of s. 22 would put a premium on ignorance of the general criminal law. Contrary to the law's intent, it would furnish a disincentive to the dispelling of ignorance as to the provisions of the criminal law governing the destroying, damaging, using, disposing of or otherwise dealing with anything which answers the description of property. A common law right over or in respect of property, whether actually possessed or mistakenly claimed, would override any provision of the general criminal law relating to property of which the person claiming the right was ignorant, though the provision in question did not relate to the rights of any other person over or in respect of the property. The wider interpretation unduly subverts the capacity of the criminal law to serve the public interest, for it would go far towards frustrating its broad educative and deterrent function (especially in relation to statutes creating regulatory offences). On the other hand, it is understandable that s. 22 should operate to suspend the sanctions which the criminal law imposes for conduct which causes another to part with property or which infringes another's rights over or in respect of property when the offender honestly believes that he is entitled to engage in that conduct by reason of a right he mistakenly believes himself to have. The narrower interpretation of s. 22 acknowledges that, while a person's ignorance of his private rights should not expose him to criminal punishment for what he does or omits to do under an honest mistake as to those rights, it is necessary in the public interest to leave the first paragraph of the section to operate generally over the criminal law. It is therefore necessary to give to s. 22 the narrower interpretation, holding that it applies only to offences in which the causing of another to part with property or the infringing of another's rights over or in respect of property is an element. So understood, does s. 22 apply to any offence created by s. 54 of the Act?
