dient thereof. But clearly enough the operation of the amendment is to make the provision still more effective by facilitating detection of the kind of fraud on the revenue at which it is aimed. Methylating substances, because of the qualities which have led to their being chosen as such, are unlikely to be found in food, drink, etc., unless methylated spirit has been introduced for the sake of its ethyl alcoholic content, and the amendment operates to preclude the success of a defence that the presence in food, drink, etc. of both ethyl alcohol and a methylating substance, since they could have been introduced separately from one another, does not indicate that methylated spirits has been misapplied. Much the same may be said in relation to a fractional part (referring, no doubt, to a product of fractional distillation) or ingredient of a methylating substance.
The foregoing considerations point unmistakeably to the con- clusion that both paragraphs of S. 16 are incidental to the exoner- ation of methylated spirits from the duties, or portion of the duties, imposed upon unmethylated spirits. They are natural, if not indeed necessary, concomitants of customs and excise tariffs which make methylation the qualification of spirits for preferential treat- ment as compared with unmethylated spirits. They provide safeguards against the danger that spirits, after having been dealt with by the revenue authorities on the assumption that, having been methylated, they will be applied to purposes mentioned in S. 14, may be SO treated as to be applicable to other purposes.
It is evident, therefore, that S. 16 (b) is within the legislative power conferred by par. (xxxix.) in association with par. (ii.) of S. 51 of the Constitution, and the preliminary objection raised at the hearing of the prosecution should have been overruled.
The appeal should be allowed, the order of the magistrate dismissing the complaint should be set aside, and the complaint should be remitted to the Court of Petty Sessions at Perth for adjudication.
Appeal allowed with costs. Order of the Court of Petty Sessions at Perth set
