24. In light of the regime fixed by ss 112, 113, 114 and 115 of the Act, I would be in doubt that there is any room for a Calderbank v Calderbank offer to be made in proceedings in the Tribunal. I would think an Offer of Compromise that does not comply with that regime cannot operate as an offer of compromise at all. The existence of that regime moreover, seems to mean Calderbank offers are unnecessary: in Cutts v Head at page 610, Oliver LJ., speaking of the Calderbank letter said that "it should not be thought that ... such a letter can now be used as a substitute for a payment into court, where a payment into court is appropriate." However, the Calderbank letter has been said to be "such a useful and flexible weapon for litigants" (see Henderson v Amadio, FCA, Heerey J, 22 March 1996_)_ that I should not rule that the provisions of the Act in ss112-115 impliedly preclude one being sent. In any event, the Settlement Offer, in mentioning a Calderbank point, was hardly in the form of a conciliatory letter offering a compromise - or even in the form of a letter, for that matter. Possibly even it was intimidatory. Nor did it specify an actual amount for costs which would be accepted to see the matter finalized, as it might have done. Strictly, I doubt it even mentions a Calderbank amount. Also, it was not straight forwardly a Calderbank offer - it says that it is made in accordance with the principles in that case and in Cutts v Head, but how can this be so if it purports to be an offer of compromise under Part 4 Division 8 of the Act? Expressing it within the context of an Offer of Compromise, I think, confuses the issue and robs it of a distinctly Calderbank effect also. In any event, even if a Calderbank type offer was successfully conveyed by the Settlement Offer, I would still be not under any obligation to award costs to the Applicant. A Calderbank offer (if this was one) cannot fetter my discretion on costs under s109. That discretion rests with me and I cannot be compelled to exercise it one way or the other providing I proceed "judicially" as that expression is understood. And I am satisfied there are discretionary considerations pointing away from an award of costs to the Applicant.
