of the section, if he is satisfied that the agreement for sale has been made in good faith and not for the purpose of evading the payment of land tax, and that the agreement is still in force as to all of which matters the decision of the commissioner shall be final and conclusive. The assessments in question were made by the deputy commis- sioner acting under a delegation of powers pursuant to sec. 8. In his instrument of delegation, the commissioner has not included the power of exemption under the proviso to sec. 37 (1), but, on the contrary, he has expressly excluded that section.
The foundation of the appellant's claim that he is not liable in respect of the parcels of land consists in transactions with one or other member of his family. If these transactions are accepted as real and if to them is conceded a validity which is not destroyed by sec. 63 of the Land Tax Assessment Act 1910-1934, the questions which the appeals raise may be stated under the following heads :-
(1) When the appellant, in 1914, transferred King's Chambers to a daughter named Mrs. Neven, did he remain liable to land tax in respect of the land under sec. 37 (1) ?
(2) After Mrs. Neven's death, in March 1917, intestate, did he become liable on the further ground that he had acquired the sole beneficial interest in the assets of her estate, of which also he was administrator ?
(3) Did he SO dispose of the same land in June 1927 to a grandson named R. F. Cooper as to cease under sec. 37 to be liable to have the land included in his assessment ?
(4) Did he SO dispose of the land known as "Spencer's" in June 1931 to daughters named Mrs. Barrett and Mrs. Hammond as to cease under sec. 37 to be liable to have the land included in his assessment ?
(5) Was the power of the commissioner under the proviso to sec. 37 (1) to exempt the appellant exercised, particularly in respect of the sale to his grandson R. F. Cooper ?
(6) Does sec. 21 of the Land Tax Assessment Acts authorize the amendments made by the commissioner from which this appeal is brought ?
It is convenient to deal with this last question before the others. The deputy commissioner made the amendments or alterations
