Sections 233B(1)(cb) and 235(2) do not contravene s 80 of the Constitution. Section 80 requires that if there is a trial on indictment of any offence against any law of the Commonwealth it shall be by jury. The sections now in question do not provide to the contrary. If there is a trial by jury the ordinary incidents of such a trial will apply; the judge will continue to exercise his traditional functions, and, for the purpose of imposing a sentence within the limits fixed by the law, will form his own view of the facts, provided that that view is not in conflict with the verdict of the jury. Section 80 says nothing as to the manner in which an offence is to be defined. Since an offence against the law of the Commonwealth is a creature of that law, it is the law alone which defines the elements of the offence. The fact that s 80 has been given an interpretation which deprives it of much substantial effect provides a reason for refusing to import into the section restrictions on the legislative power which it does not express. It has been held that s 80 does not mean that the trial of all serious offences shall be by jury; the section applies if there is a trial on indictment, but leaves it to the Parliament to determine whether any particular offence shall be tried on indictment or summarily. This result has been criticised, but the Court has consistently refused to reopen the question and the construction of the section should be regarded as settled [210] . To understand s 80 as requiring the Parliament to include in the definition of any offence any factual ingredient which would have the effect of increasing the maximum punishment to which the offender would be liable would serve no useful constitutional purpose; indeed the Parliament might feel obliged to provide that some offences, which would otherwise be made indictable, should be triable summarily.
1. Section 235 relevantly provided: "(2) Subject to sub-sections (3) and (7), where - (a) a person commits an offence against sub-section 231(1), section 233A or sub-section 233B(1); and (b) the offence is an offence that is punishable as provided by this section, the penalty applicable to the offence is - (c) where the Court is satisfied - (i) that the narcotic goods in relation to which the offence was committed consist of a quantity of a prescribed narcotic substance that is not less than the commercial quantity applicable to that substance; or (ii) that the narcotic goods in relation to which the offence was committed consist of a quantity of a narcotic substance that is not less than the traffickable quantity applicable to that substance and also that, on a previous occasion, a court has - (a) convicted the person of another offence, being an offence against a provision referred to in paragraph (a) that involved other narcotic goods which consisted of a quantity of a narcotic substance not less than the traffickable quantity that was applicable to that substance when the offence was committed; or (b) found, without recording a conviction, that the person had committed another such offence - imprisonment for life or for such period as the Court thinks appropriate; (d) where the Court is satisfied that the narcotic goods in relation to which the offence was committed consist of a quantity of a narcotic substance that is not less than the traffickable quantity applicable to the substance but is not satisfied as provided in paragraph (c) - (i) if the narcotic substance is a narcotic substance other than cannabis - a fine not exceeding $100,000 or imprisonment for a period not exceeding 25 years, or both; or (ii) if the narcotic substance is cannabis - a fine not exceeding $4,000 or imprisonment for a period not exceeding 10 years, or both; or (e) in any other case - a fine not exceeding $2,000 or imprisonment for a period not exceeding 2 years, or both. (3) Where - (a) the Court is satisfied that the narcotic goods in relation to which an offence referred to in sub-section (2) was committed consist of a quantity of a narcotic substance that is not less than the traffickable quantity applicable to that substance, but is not satisfied as provided in paragraph (c) of that sub-section in relation to those narcotic goods; and (b) the Court is also satisfied that the offence was not committed by the person charged for any purposes related to the sale of, or other commercial dealing in, those narcotic goods, notwithstanding paragraph (d) of that sub-section, the penalty punishable for the offence is the penalty specified in paragraph (e) of that sub-section. (4) An offence referred to in sub-section (1) or (2) may be prosecuted summarily or upon indictment or, where the law of the State or Territory in which the proceedings are brought makes provision for an offender who pleads guilty to a charge to be dealt with by the Court otherwise than on indictment, the Court may deal with an offender in accordance with that law." Sub-section (7) provided the penalties that may be imposed when a court of summary jurisdiction determines proceedings summarily.
