38 In Wallam, McLure JA also relied upon the enactment of s 304 of the Criminal Code as an aid to the construction of the transitional provisions. Again with respect, in my opinion this is not one of those cases in which later legislation can properly be used to shed light upon the proper construction and effect of earlier legislation. It is clear from the extrinsic materials, including the Parliamentary Debates and Explanatory Memoranda relating to the Criminal Code Amendment Bill 2003, which resulted in the enactment of s 304 of the Criminal Code, that the legislation was intended to give effect to recommendations made in the 1983 General Review of the Criminal Code undertaken by Mr M Murray QC (as his Honour then was) (Western Australia, Parliamentary Debates, Legislative Assembly, 3 April 2008, 6158 (Mr J A McGinty, Attorney General)). The Criminal Code Amendment Bill 2003 was introduced and read first in the Parliament on 3 April 2003, prior to the publication of the Report of Standing Committee to which I have referred, or the amendment of the Sentencing Legislation Amendment and Repeal Bill 2002 which gave effect to that recommendation. It seems a fair inference from the relative timing of the two pieces of legislation, and the historical origin of the Criminal Code Amendment Act 2004 (WA), that if there is any anomaly when the maximum penalty for an offence contrary to s 304(2) is compared to the maximum effective penalty for a contravention of s 294 of the Criminal Code, it is to be attributed to an inadvertent Parliamentary oversight rather than the application of the mind of the Legislature to the effect of the Sentencing Legislation Amendment and Repeal Act 2003 at the time of enacting the amendments to the Criminal Code. And in any event it is I think a matter of some speculation as to whether there is in fact an anomaly in relation to the maximum penalties available in respect of those two offences. Section 294 can potentially apply to a range of conduct which might include conduct within a relatively low range of seriousness - for example, an attempt to strike somebody with a projectile with intent to resist lawful arrest, whereas s 304(2) potentially embraces very serious conduct - for example endangering the life of a person with intent to harm. Accordingly, the fact that the Legislature provided a maximum penalty of 20 years for a contravention of s 304(2) at a time when any penalty imposed for a contravention of s 294 was subject to the transitional provisions does not, with respect, seem to me to shed any light upon the proper construction of those transitional provisions,
