Although it has been said that in order to create a genuine dispute it must be shown that the organization "really wants what it demands" (Cohen [14] ), this does not mean that the organization or its members must be intent on obtaining forthwith every item which is mentioned in the log of claims or the particular terms and conditions of employment in the form and in the amounts in which they are expressed in the log. The requirements of the ambit doctrine not only promote, but necessitate, the making of inflated demands. Because the provisions of an award which settles a dispute must be "relevant", "reasonably incidental", or "appropriate" to the statement of what is in dispute (Reg. v. Galvin; Ex parte Amalgamated Engineering Union, Australian Section [15] ; Reg. v. Holmes; Ex parte Victorian Employers' Federation [16] ), it is essential that the log is so expressed as to create a dispute which has sufficient breadth and scope: (1) to ground a general industry award free from objections on the ground of ambit; and (2) to justify variations of the award which may be made from time to time under s. 59 in order to preserve the settlement of the initial dispute or to prevent a fresh dispute arising: Reg. v. Kelly; Ex parte Australian Railways Union [17] : Reg. v. Isaac; Ex parte State Electricity Commission (Vict.) [18] . For this reason, and because disagreement generating a dispute may relate to what is to be done in the future rather than the present, it is unnecessary for an organization to insist that its demands be implemented immediately in order that they be bona fide. These demands, known as "ambit claims", are designed to establish the margins of the dispute and to justify the making of an award, if not initially, later by way of variation, within those margins. So, money claims for wages and allowances which seemed to be extravagant when made, appear, in the light of inflation, to be reasonable some years later.
