1 This proceeding concerns an appeal by the appellant taxpayers against an assessment to duty under the Duties Act 2000, which was based on a valuation of the dutiable property of approximately $5 million.
2 Under s109 of the Taxation Administration Act 1997 ("the Act"), the Commissioner's case on an appeal is limited to the grounds on which the taxpayers' objection to assessment were disallowed, unless the court otherwise orders.
3 In the application before me, the respondent Commissioner seeks leave to rely upon a further ground, in addition to those relied upon in disallowing the taxpayers' objection, namely, that the true value of the dutiable property is in fact more than $8.6 million.
4 The taxpayers argue that the Commissioner is thereby seeking to reassess their tax liability, something which can no longer be done by virtue of a 3 year time limit in s9 of the Act. The principal question before me is whether the power conferred by s109 is limited in some way by s9. If there is no such time limit, the secondary question is whether, in the exercise of my discretion, I should grant the Commissioner leave to rely on the further ground.
Relevant facts
5 The taxpayers were two members of a group of developers who agreed to purchase and develop the former Pentridge Prison site under a joint venture agreement. Disputes arose between the joint venturers, which were resolved by an agreement in December 2000 to subdivide and develop different parts of the site. By a transfer of land dated 5 April 2002, the part of the site known as Lot J was transferred to the taxpayers as tenants in common. The consideration was described as "an agreement to partition dated 5 December 2000".
6 In early July 2002, the taxpayers lodged the transfer with the Commissioner for assessment to duty, together with a statutory declaration which referred to a valuation of the property for stamp duty purposes of $5,150,000.
7 On 14 October 2002, the Commissioner issued a notice of assessment pursuant to s8(1) of the Act, assessing duty in the sum of $283,250, based on the taxpayers' valuation. The taxpayers paid the duty on 14 November 2002.
8 On 11 December 2002, the taxpayers lodged a notice of objection challenging both the validity and the correctness of the assessment on various grounds. It is not necessary for present purposes to describe in detail all the grounds of objection. It is sufficient to note that the taxpayers assert that if the transaction is dutiable and not exempt (both of which are contested), then the dutiable value of the property is "nil or an amount less than $5,150,000".
9 On 9 May 2003, after the provision of certain additional information requested by the Commissioner, a notice of determination was issued. In it, the Commissioner rejected arguments that the transfer was exempt under either s27 or s36 of the Act. As the transfer was not as the result of a sale, the dutiable value of the property was said to be the amount for which it might reasonably have been sold in the open market at the time of the transfer, free from any encumbrances. In confirming the assessment, the Commissioner expressly accepted that the unencumbered value of Lot J was $5,150,000, on the basis of the taxpayers' valuation report.
10 The taxpayers were dissatisfied with the determination. On 2 July 2003, they gave notice requesting that the objection be referred to this court for hearing as an appeal. It is not entirely clear why it took the Commissioner until 6 October 2004 to refer the appeal to this court. The serving and answering of a request for further and better particulars of the objection occupied some time in August 2003, but otherwise there is no reason proffered for such a long delay. During this period, the taxpayers' solicitors made several attempts to find out what was happening and to require the Commissioner to refer the dispute to court.
11 The Commissioner's letter of 6 October 2004 advised that the matter had been referred to this court as an appeal. It also sought further documents and placed the taxpayers on notice that the Commissioner might wish to produce fresh valuation evidence in respect of Lot J and seek leave to amend the grounds of disallowance of the objection. The possibility of such an application was repeated in the Commissioner's letter of 13 January 2005.
12 On 24 June 2005, I ordered the taxpayers to serve by 18 July 2005 copies of the documents which the Commissioner had been seeking since his letter of 6 October 2004. The taxpayers did not comply fully with my order, or provide all of the documents sought, for more than a year, notwithstanding numerous requests by the Commissioner to do so. It was not until late September 2005 that the taxpayers' solicitors advised that all relevant documents had now been provided.
13 Within 8 weeks of receiving the last of the requested information, the Commissioner had obtained his own valuation of the dutiable value of Lot J from the Valuer-General's Office. That assessed the dutiable value as $8,680,000, which would attract duty of $477,400, being an additional $194,150 on top of the duty already paid. On 17 November 2005, the Commissioner served a copy of that valuation and formally gave notice to the taxpayers that he would seek to rely on the following new ground:
