Thus there are many cases where circumstances reasonably call for an investigation to be made before the court could properly pronounce in favour of (or against) a will. They would involve serious hardship for the contesting party who thereby performs a public service, if that unsuccessful party were nonetheless required to pay his or her own costs. I do not consider, therefore, that this should be the inevitable consequence of coming within the second exception, though in some cases that may be the proper order.
18 In Re Estate late Hazel Ruby Grounds, Page v Sudawaie [2005] NSWSC 1311, Campbell J, as his Honour then was, noted that an overlap had been recognised by the Court of Appeal between the two exceptions referred to in Shorter and that, if a case for decision fell within that area of overlap this meant that one of the exceptions suggested that the appropriate order concerning costs should be different to the order which is suggested by the other exception. His Honour said (at [30]):
In that area of overlap, the principles which are recognised by the two exceptions are insufficient to produce a result. It is a matter for the trial judge, in light of the circumstances of the particular case before him or her, to decide which costs order better achieves justice.
19 There, his Honour noted that the question whether some special costs order ought to be made in favour of an unsuccessful defendant so as to relieve him (or her) of the burden of costs falls for determination on the basis of whether there were circumstances which afforded reasonable grounds for a defendant's opposition of the grant of probate.
20 Here, it is not suggested that the defendant's conduct of the litigation was unreasonable per se. It was noted by Counsel for the defendant that the issue as to the deceased's capacity was, as I perceived it, a more difficult question. Ms Hudson had put forward valuable evidence (particularly from the expert witness called on her behalf, Professor Westmore) in order to assist the court to determine the issue of testamentary capacity.
21 It was submitted that Ms Hudson filled the role of a necessary contradictor to the proceedings and had raised in her affidavit and in the evidence tendered before the court a number of matters which had not been otherwise before the court when the statement of claim seeking s 18A declarations and consequential relief was issued.
22 I accept that that is the case. However, there was an array of evidence arguably relevant to the background circumstances but ultimately not relevant on the determination as to whether the deceased had testamentary capacity (such as evidence of various alleged delusions held by the deceased in relation to his next door neighbour and a developer seeking to obtain an advantage in relation to his property; his concerns in relation to his tenure or employment at the University; and his financial circumstances) which, it seems to me, were never likely to be said to be delusions capable of affecting the dispositions made under the will. The adducing of this evidence meant that costs were inevitably incurred by the plaintiffs in responding thereto.
23 Further, it was submitted by Mr Willmott, and I accept, that Professor Westmore's evidence was not supportive of the proposition that, as at the date on which the documents were signed, the deceased lacked testamentary capacity. Rather, Professor Westmore's evidence, as I understood it, was that by the time the deceased committed suicide he was psychotic and that psychosis would have taken some time to develop. Professor Westmore was unable to say when that psychosis would have developed and could not see anything on the face of the testamentary dispositions to suggest that either of them was affected by any delusion or psychosis at that stage. While on the one hand Ms Hudson, to adopt the terminology referred to in Redroff, may be said to have performed a public service in putting forward the circumstances which reasonably called for an investigation in relation to the deceased's testamentary capacity, it also is the case that Ms Hudson was opposing a grant of probate the effect of which would have been, if she were successful on the whole of her claim, to leave the estate to pass on intestacy to her. She therefore had a clear interest in the outcome of the proceedings. In those circumstances, I think the appropriate orders are as I have indicated above and I so ordered.
