The first question is whether the respondents made a full and true disclosure of all the material facts relating to the cottage necessary for the making of the original assessment. It is contended for the appellant that they failed to do so because they declared that the value of the cottage at the date of death was £2,750 whereas its true value was in fact £3,200. Apart from the provisions of s. 10 (2) of the Act I should have thought it would only be necessary for an administrator to make a full and true disclosure of the descriptions of the items of property comprising the estate to enable the commissioner to make an assessment. But the administrator is required in his statement to set forth the descriptions and values of the items comprising the estate and this would seem to require him to make a full and true disclosure of the values as well as the descriptions of the items. Even so, an administrator can only make a full and true disclosure of facts which are capable of being ascertained and, in the case of values, he has to disclose, not an objective fact, but information which is only a fact so far as a matter of estimation and opinion can be a statement of fact. It is true, as Mr. Kitto said, that the value of property is often an issue in a court, and this issue has often been described as an issue of fact. But the contrast is between questions of law and issues of fact, and it is in this respect that an adjudication upon the value of property is an issue of fact. The task of the court in assessing compensation was described by Dixon J. in Minister of State for the Navy v. Rae [1] as follows: "In reaching a conclusion as to compensation for the taking of a piece of property such as that now in question, it is necessary, or at all events wise, to pursue as many means of estimation as are open, to compare them, and then, as an exercise of judgment, to fix what, upon considerations this process suggests, appears to be a fair compensation." In Hazeldell Ltd. v. The Commonwealth [2] , Isaacs A.C.J. said, "The value of land, where there is no market price, is always a matter of opinion." In Secretary of State for Foreign Affairs v. Charlesworth, Pilling & Co. [3] , Lord Hobhouse, delivering the judgment of the Privy Council, said: "It is quite true that in all valuations, judicial or other, there must be room for inferences and inclinations of opinion which, being more or less conjectural, are difficult to reduce to exact reasoning or to explain to others." The extent to which a statement of opinion is a statement of fact was discussed in Bisset v. Wilkinson [4] and Fitzpatrick v. Michel [5] . The administrator is not often a skilled valuer. He must usually rely on the valuations of experts. In my opinion, an administrator who makes a full and true disclosure of the description of each item of property comprising the estate, places a value on it which he honestly believes to be its true value, and makes a full and true disclosure of the expert valuations on which he relies, makes a full and true disclosure of its value for he discloses all that he knows or is capable of knowing of its value. This is what the administrators did in the present case and the appellant cannot therefore rely on s. 20 (2).
