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 [33] , 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 [34] . 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 organisation 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.
Of course, inflation is not the only factor which might bring claims that at first appear to be extravagant within the realm of the attainable. Changes in productivity, technology, work practices or industrial relations generally may also have to be taken into account in framing a log of claims that is capable of grounding an industrial dispute.
