described in the Schedule for the specified term, subject to certain
reservations expressed in the following words :- Except and always reserved to Us, Our Heirs and Successors, full power during the term hereby granted, from time to time to sell to any
OF person or persons all or any unsold portion of the said demised AUSTRALIA. premises, subject to any claim for improvements that may be
lawfully made in pursuance of the said Regulations also to
resume and enter upon or dispose of in such other manner as for the public interest to Us, Our Heirs and Successors, may seem best, such part or parts of the said demised premises as may be required for
otherwise facilitating the improvement and settlement of the Colony sell any mineral land comprised within the said demised premises, and, subject to the rights of the lessee aforesaid, to license to occupy, or to sell any other portion of the said premises at any time, and with a right of immediate entry." It is not disputed by the suppliants that under these reservations the Crown had power to sell any of the land comprised in the lease, but it is contended that the sale contemplated was an absolute immediate sale for cash only and not a conditional sale, and that, even if a conditional sale was included, the reservation only extended to a sale upon the particular conditions specified in Part IV., and would not authorize a sale on any conditions that might be pre- scribed by future Regulations.
If this view is correct, the lease created an estate in the land which could not be diminished by the Crown by means of any disposition of the land inconsistent with the continuance of the estate SO created. A covenant not to make such an ineffectual disposition could not, because it need not, be implied. If, on the other hand, the reserved power of sale extended to any sale that might be made in pursuance of future Regulations, the implied covenant, to be of any service to the suppliants, must be that the Crown would not exercise to the prejudice of the lessee the power of making new Regulations for the sale of land on different terms, or, at least, that it would not dispose of the leased land under any such new Regulations. It is difficult, and
I think impossible, to imply such a covenant against the Crown.
