and earthy substances but not to include coal. It was faintly con- tended that this definition, including as it does rocks and earthy substances, is SO wide that the regulations were not authorized by the defence power even during hostilities. In my opinion there is no substance in this contention. The words "all rocks and earthy substances " should be construed ejusdem generis with the preceding words and refer to rocks and earthy substances containing metals, the ores of metals &. Further, effect must be given to the pro- visions of S. 46 (b) of the Acts Interpretation Act 1901-1941 SO that if any words in the definition following the words "metals and the ore of any metals" would have the effect of making the regulations beyond the defence power, the definition must be construed as if such words were omitted, and the regulations held to be valid to the extent to which they are not in excess of that power (Pidoto v. Vic- toria 1 ). It is not in my opinion possible for the court to say that the control of the production and supply of all metals during hostilities had no sufficient connection with the prosecution of the war, SO that the regulations for this purpose would be authorized by the defence power when they were made, at least in relation to metals and the ore of any metals.
The principal regulation is reg. 6. Regulation 6 (1) provides, SO far as material, that the Controller shall have power, on behalf of the Commonwealth, to operate, control and direct the production and supply of minerals, and for that purpose to make such orders as he
thinks necessary or expedient. Regulation 6 (2) provides in particular, but without limiting the generality of the last preceding sub-regulation, the Controller, on behalf of the Commonwealth, may exercise certain specific powers. These include the power to-(a) take possession of any land (b) use or authorize the use of such land for the production and supply of minerals either by the Common- wealth or by any other person (e) compulsorily acquire the property in, or requisition the use of, any machinery equipment or plant for the production and supply of minerals; (f) make contracts or agree- ments for the production and supply of minerals. Regulation 10 provides for compensation in relation to things done in pursuance of pars. (a), (b) or (e) of reg. 6 (2).
The only order made under reg. 6 (1) prior to 1947 was an order made on 27th April 1942 directing all persons, who had in their possession or under their control any mica, to retain and hold the same for and on behalf of the Commonwealth and to sell, supply and deliver it to the Commonwealth as directed. It would appear that no further orders were necessary during this period because the
