Under the Crimes Act (s. 323), a person who aids, abets, counsels or procures the commission of the offence of murder may be tried, indicted, or presented and punished as a principal offender. The offence of incitement to murder is treated differently. Indeed, as the present case illustrates, a person can be convicted of the offence of incitement to murder notwithstanding that there has been no murder. Nonetheless, it would seem unlikely that individual members of the Victorian Parliament which enacted the Sentencing Act had a specific subjective intention that the maximum penalty for the statutory offence of incitement to murder should be reduced to imprisonment for only five years. Indeed, it would seem highly likely that, if the question had been specifically raised, the majority, and probably all, of the members of the Victorian Parliament would have been of the subjective view that a maximum penalty of imprisonment for five years was quite inadequate. The subsequent amendment of s. 321I(1) of the Crimes Act by the Sentencing (Amendment) Act perhaps confirms that that is so. However, there is a clear distinction between the positive identification of a court-induced mistake by the legislature and speculation or an assumption that one particular effect of the amendment of a general legislative provision either was not adverted to or was unintended by the individual members [9] . In particular, a subsequent, but inapplicable, legislative reduction of the maximum penalty for the offence for which a convicted person is being sentenced could justifiably be seen by the sentencing judge as less significant in a case where it was apparent that the reduction had resulted from an identified court-induced mistake by the legislature than in a case where all that could be said was that it was unlikely that the individual members of the legislature had subjectively adverted to that particular effect of a general amending provision.
