The caveator should, if he so desired, have taken the course of fighting the question of incapacity at his own risk as to costs; he cannot now be allowed to raise the question."
Later, when dealing with the question of costs, his Honour said (at 169;52):
"It may be that the practice laid down by the rules creates a little difficulty, and that, even where a person merely wants proof in solemn form, it is necessary to lodge a caveat; but in such case the caveator should give notice to that effect in or together with his caveat. The absence of such notice leads the executors into expense which is quite unnecessary; they obtain a rule nisi, affidavits are filed by both sides, there is a motion for a rule absolute, and, if a prima facie case is made out, the matter is ordered to proceed as a contested cause, and then a statement of claim is filed. Not till then does the caveator show his hand. Such a practice cannot be allowed, because all the costs up to that point would have been incurred unnecessarily through the caveator not having taken steps to inform the executors that he only wanted proof in solemn form. The caveator is, therefore, entitled, out of the estate, to his costs as of an application to prove the second codicil in solemn form; but he must pay all further costs incurred by the executors by reason of the filing of the caveat."
Although, in the first of his judgments in Beatson v Perry , Walker J referred to the "dearth of authority" on the question, it should be noted that, in the course of the judgment delivered by him in Hay v Simpson (1890) 11 LR (NSW) Eq 109 at 114-115), Manning J said:
"… In this case it is true the opponent of the Will can claim more latitude, for he is one of the next of kin, and the next of kin have a right to have the Will proved in solemn form, that is, per testes and in open Court, though I think that even next of kin must shew some small justification for doing so - for instance, they may use their right by unreasonable delay. However, there is no doubt that as a general rule they may claim to have the Will proved in solemn form at the cost of the estate, but they must go no further than that; they must not put the estate to additional expense, they cannot fire off two barrels at once, and, because there was only one report, say that there was only one barrel - they must in fact say, and clearly say, that proof in solemn form is all they require, notwithstanding the fact that there is here no rule of Court to compel them to do so, and they must not file an ambiguous plea, keep to themselves what they really intend, and then, when all hope of succeeding on the other issues has failed, say that all they wanted was a proof in solemn form. In cases of this kind the general practice is that the plaintiffs prove the Will, and perhaps give evidence as to the circumstances attending the preparation of the Will as well as its execution, leaving the respondents to go into their case and turn back upon the plaintiffs the onus of proving the soundness of the testator's mind; but there is nothing whatever to compel the plaintiffs to take that course, and it is clear that counsel for the plaintiffs would never take the course of going fully and elaborately into evidence of a testator's capacity if they were merely called upon to give roof in solemn form."
Finally, I record that, in the course of his judgment in Hughes v Public Trustee (Court of Appeal, 19 August 1980, unreported) Hutley JA (with whom Hope JA and Glass JA agreed) said:
"The caveat also required that the Will be proved in solemn form. That, according to my understanding of the practice in New South Wales until the Supreme Court Act 1970, came into force, only entitled him to cross-examine the attesting witness. I know of no change brought about in this practice by the Supreme Court Act or the rules, and counsel were prepared to concede this."
As is apparent from the second of the judgments delivered by Walker J in Beatson v Perry , if one seeks to raise a ground of invalidity other than want of due execution, one is required to file, not, a caveat requiring only proof in solemn form, but, a general caveat, and, further, one is required, on the return of a summons for an order that the caveat cease to be in force, to be in a position then to tender evidence raising at least a prima facie case of the ground of invalidity relied upon, in default of which the order will be made, with costs against the caveator: see In the Will of O'Driscoll (1929) 29 SR (NSW) 559; 46 WN (NSW) 176.
