National Trustees, Executors and Agency Co of Australasia Ltd v Federal Commissioner of Taxation

The High Court of Australia considered an appeal by the executors of the estate of William Mitchell, deceased, against an assessment of estate duty by the Federal Commissioner of Taxation. The dispute arose from the Commissioner's inclusion of real property gifted by the deceased to his children within one year of his death as part of his dutiable estate. The executors contended that this inclusion, based on section 8(4) of the *Estate Duty Assessment Act 1914*, was invalid.

The legal issues before the Court were whether section 8(4) of the *Estate Duty Assessment Act 1914* was valid, and consequently, whether the estate duty had been correctly computed at a single rate on the combined value of the deceased's property at death and the gifted property. The appellants argued that the inclusion of gifts made within a year of death constituted a separate subject of taxation, thus contravening section 55 of the Constitution, which requires taxation laws to deal with only one subject. They also relied on *Waterhouse v. Deputy Federal Commissioner of Land Tax* to argue that the Act improperly taxed individuals in respect of property they no longer owned.

The Court reasoned that the *Estate Duty Assessment Act 1914* and the *Estate Duty Act 1914*, read together, imposed a tax on a single subject: the estate of a deceased person. It was held that the inclusion of gifts inter vivos made within a year of death was a common and accepted feature of estate duty legislation, both historically and at the time of the Constitution's enactment, designed to prevent evasion. This practice was considered to be within the scope of what constituted an "estate duty" and therefore did not offend section 55 of the Constitution by introducing a second subject of taxation. The Court distinguished *Waterhouse's Case*, finding it did not apply to the present circumstances.

The High Court answered both questions referred to it in the affirmative. This meant that section 8(4) of the *Estate Duty Assessment Act 1914* was deemed valid, and the Commissioner's assessment of estate duty at a single rate on the deceased's property at death and the gifted property was upheld.
