This is a case stated by the learned Chief Justice of South Aus-
tralia for the opinion of this Court, pursuant to sec. 27 (1) of the
Estate Duty Assessment Act 1914-1916. The material facts are
that Thomas Roger Scarfe died on 19th March 1915. On 19th July
1915 his executors, as administrators within the meaning of the
Federal Act, furnished to the respondent a return purporting
to be a full and complete return of all the testator's estate in Aus-
tralia. On 24th December 1915 the respondent issued a notice
of assessment stating the amount of duty payable at £44,145 18s.,"
and requiring payment on or before 24th January 1916. On
3rd March 1916 an amended assessment was issued increasing the
amount of duty to £45,609. On 31st March 1916 the appellants
paid £45,000 in part payment of the last-mentioned assessment.
On 3rd May 1916 the balance of duty according to the last men-
tioned assessment, viz., £609, was paid. Stopping there for a
moment, it will be observed that " the last payment on account of
duty on" the assessment was 3rd May 1916. As a fact, the testator
was at the time of his death entitled to a contingent interest under
the will of George Scarfe, who died in 1903, This contingent
interest was not mentioned in the return made by the appellants,
and was unknown to the respondent until after the final payment.
The interest was contingent on the death of a sister of the testator,
unmarried, That event occurred on some date subsequent to the
final payment. Afterwards, on 23rd May 1919, the respondent
amended the assessment by including the value of the interest, and -
gave notice of the details of alterations of the assessment, showing -
the dutiable balance to be £46,722 12s., that is to say, an increase
of £1,113 12s. The appellants objected to this, and appealed.
