The question upon which the validity of the regulations depends is whether it is right to say that a law which does what these regulations do, "in the way of changing or creating or destroying duties rights or powers" (South Australia v. The Commonwealth [1] ), can fairly be said, in the situation of recognizable danger which confronts Australia in these days, to possess the character of a law with respect to defence. What, then, is the legal effect of these regulations? Briefly, they prohibit a variety of transactions except with the consent of the Treasurer of the Commonwealth, and they place a restriction upon his power to refuse consent or to grant it upon conditions. The transactions, shortly described, are: (i) the issue by a company of authorized capital so as to bring the total issued within two years, plus the amounts within that period borrowed and not repaid under certain kinds of securities and under unsecured loans, to more than £10,000 (reg. 6); (ii) the making by a company of any call upon certain classes of shares unless stated conditions are fulfilled (reg. 7); (iii) the accepting or receiving of a deposit (an unsecured loan) by a company (other than a bank, a declared pastoral company, a building society or a co-operative society) if the amount borrowed and not repaid during the preceding two years (including the deposit), plus the amount of authorized capital issued during that period and the amount borrowed and not repaid under a security given during that period, exceeds £10,000 (reg. 8 (a)); (iv) the payment of interest by such a company as in (iii), on certain deposits, at a rate higher than ten shillings per centum per annum (reg. 8 (b)); (v) the issue or giving by a person, of a security, which means bond, debenture, debenture stock, inscribed stock, mortgage or charge (except to the Commonwealth or State, an authority of the Commonwealth or of a State, a bank, a declared pastoral company, a building society or a co-operative society), unless the amount is limited in a manner similar to (iii) and the security is not a first mortgage or charge over land at a rate of interest exceeding £4 10s. 0d. per centum per annum (regs. 10, 12, 13); and (vi) the paying or charging by a person of interest on certain securities at a rate higher than the rate payable under the security, or the repayment or receipt of an amount of capital in excess of the amount borrowed under a security (reg. 11). The consent of the Treasurer may be granted unconditionally or subject to such conditions as he thinks fit, or refused (reg. 16). It is not to be refused, nor is it to be granted subject to a condition "except for purposes of or in relation to defence preparations" (reg. 17 (1), (2)). The substantial effect is that the Treasurer is empowered, provided that he acts "for purposes of or in relation to defence preparations", to restrict, in the case of companies, the issue of share capital, the making of calls, the borrowing of money, and the rate of interest which may be paid; and to restrict, in the case of individuals, the giving of securities and the rate of interest payable.
