II. sum, and that consequently the plaintiffs have not suffered any
loss by the action of the Government. I think that this argument is fallacious. It does not follow that, because a particular result may lawfully be effected in an authorized way, the same result may validly be effected in another way which is unauthorized. In my judgment the words "shall have power to reduce," do not, etymologically, include a power to reduce to nothing or abolish.
I express no opinion on the question of how far reduction, not being abolition, could be carried. Apart from the guarantee, indeed, this point would not be arguable. If one person agrees to render services for another at a specified rate of charge, with a power to that other to reduce the rate, it cannot be contended that the power may be exercised SO as to require the services to be rendered gratuitously. The arguments already adverted to satisfy me that in this case the guarantee to make up the actual earnings to £5,600, introduced into a contract made in 1889 by the Government of an Australian Colony, which was presumably and in fact interested in keeping down its public expenditure, is not sufficient to give such an altered meaning to the word reduce" in that contract.
It follows, in my judgment, that the Order in Council of 4th December 1906 was not authorized by the power to reduce con- tained in Article 5, and was wholly inoperative. The result is that the Commonwealth were bound to account to the plaintiff's at the rates fixed in 1902 until they should be lawfully reduced, which has not yet been done.
It is admitted that, in this view, the amount for which the Commonwealth were bound to account to the plaintiffs for messages sent under the agreement of 1889 in respect of the period from 6th December to 31st December is £605 12s. 10d.
Three other questions were submitted and argued, which, in the view which I take of the first question, are not immediately material, but I will briefly express my opinion upon them.
In the year 1883 the Tasmanian Government entered into an informal agreement, not in writing, to pay to the plaintiffs a lump sum of £50 per annum for certain services in connection with the transmission of shipping news, and always continued to pay that sum by quarterly instalments, as a sum payable outside
