Was the primary judge correct in The application of the tiebreaker provisions of the Double Tax Agreement?
19 This issue was raised by grounds 1 and 2 of the appeal and grounds 10 and 11 of the cross-appeal.
20 The parties were not in dispute that Mr Pike was a resident of Thailand for the purposes of Thai tax during the income years 2009 to 2014 (inclusive). As Mr Pike had dual residency of Australia and Thailand during those income years, it was necessary for the primary judge to consider the application of the tiebreaker provisions in Art 4(3) of the Double Tax Agreement. The Double Tax Agreement entered into force for Australian tax law purposes on 27 December 1989. As the primary judge explained at [90]:
In cases of dual residency, Article 4, cl 3 of the [Double Tax Agreement] provides for what may be described as a "tie breaker" test to determine whether an individual is deemed to be a resident of Australia or, as the case may be, Thailand…
21 Article 4 of the Double Tax Agreement relevantly prescribes as follows:
1. For the purposes of this Agreement, a person is a resident of the Contracting States:
(a) in the case of Australia, if the person is a resident of Australia for the purposes of Australian tax; and
(b) in the case of Thailand, if the person is a resident of Thailand for the purposes of Thai tax.
…
3. Where by reason of the preceding provisions, an individual is resident of both Contracting States, the status of the person shall be determined in accordance with the following rules, applied in the order in which they are set out:
(a) the person shall be deemed to be a resident solely of the Contracting State in which a permanent home is available to the person;
(b) if a permanent home is available to the person in both Contracting States, or in neither of them, the person shall be deemed to be a resident solely of the Contracting State in which the person has an habitual abode;
(c) if the person has an habitual abode in both Contracting States, or in neither of them, the person shall be deemed to be a resident solely of the Contracting State with which the person's personal and economic relations are the closer.
4. For the purposes of the last preceding paragraph, an individual's citizenship or nationality of a Contracting State shall be a factor in determining the degree of the person's personal and economic relations with that Contracting State.
…
22 The primary judge held that neither of sub-paras 3(a) or (b) applied. Mr Pike has challenged the primary judge's finding that he had an "habitual abode" in both Thailand and Australia for the purposes of sub-para 3(b) and the Commissioner has challenged the primary judge's finding that Mr Pike's personal and economic relations were closer to Thailand in the relevant years for the purposes of sub-para 3(c).
23 As to Art 4(3)(b), the primary judge at [97] found that Mr Pike had an habitual abode in both Thailand and Australia. His Honour reasoned at [97]-[99]:
As Article 4, cl 3(a) is inapplicable, one "cascades" to Article 4, cl 3(b). In each country, Mr Pike had a habitual abode. Once again though, there is nothing, in my view, to choose between Thailand and Australia. Mr Pike's life routine had two aspects. One was that as, when and for as long as necessary, and always for more than half the year, he worked in or from Thailand and occupied there premises which he had made his home. The other was that as, when and for as long as possible, he lived with his family in Australia. The length of time as between each country for these purposes varied from year to year but, in relation to each country, he had an established residential habit.
As it happens, this approach accords with the understanding evident in the OECD commentary:
The application of the criterion ... requires a determination of whether the individual lived habitually, in the sense of being customarily or usually present, in one of the two States but not in the other during a given period; the test will not be satisfied by simply determining in which of the two Contracting States the individual has spent more days during that period ... "habitual abode" [is] a notion that refers to the frequency, duration and regularity of stays that are part of the settled routine of an individual's life and are therefore more than transient ... it is possible for an individual to have an habitual abode in the two States, which would be the case if the individual was customarily or usually present in each State during the relevant period, regardless of the fact that he has spent more days in one State than in the other.
For these reasons, I reject the Commissioner's submission that Article 4, cl 3(b) confers taxing entitlement on Australia. Equally though, for those same reasons, I do not accept Mr Pike's submission that habitual abode ought to be determined just by length of residence such that Mr Pike's greater length of residence in Thailand in each year meant that, between the 2009 and 2014 income years, only in Thailand could be said to have a habitual abode
24 Mr Pike contended that the primary judge erred in holding that he had an habitual abode in both countries, when the period of time that he spent in Thailand was "considerably more" than the period of time that he spent in Australia. It was argued that the Organisation for Economic Co-operation and Development's commentary (OECD commentary) on Art 4 on which the primary judge placed reliance (which was the 2017 version) had limited utility as an aid to interpretation of the Double Tax Agreement as Art 4 of the OECD's Model Tax Convention on Income and on Capital (Model Tax Convention) is in materially different terms to Art 4 of the Double Tax Agreement. Further, it was submitted, in any event, the passage quoted at [98] of the primary judgment omitted the example given later in [19] of the 2017 version of the OECD commentary on Art 4, which reads as follows:
Assume, for instance, that over a period of five years, an individual owns a house in both States A and B but the facts do not allow the determination of the State in which the individual's centre of vital interests is situated. The individual works in State A where he habitually lives but returns to State B two days a month and once a year for a three-week holiday. In that case, the individual will have an habitual abode in State A but not State B.
It was submitted the example given is consistent with the proposition that the habitual abode question ought to have been resolved in favour of a conclusion that Mr Pike's only habitual abode was in Thailand in each of the 2009 to 2014 years.
25 The principles for construing a provision of a double tax agreement are well established. The principles contained in Arts 31(1) and 32 of the Vienna Convention on the Law of Treaties, opened for signature 23 May 1969, 1155 UNTS 331 (entered into force 27 January 1980) require treaties to be "interpreted in good faith in accordance with the ordinary meaning to be given to the terms of the treaty in their context and in the light of its object and purpose" (Art 31(1)) and provide that, in that task, recourse may be had to supplementary means of interpretation in order to confirm the meaning resulting from the application of Art 31 or to determine the meaning when the interpretation according to Art 31 leaves the meaning ambiguous or obscure or leads to a result which is manifestly absurd or unreasonable (Art 32). It is well established that the OECD commentary to the Model Tax Convention is a legitimate aid to construction: Thiel v Commissioner of Taxation [1990] HCA 37; 171 CLR 338, at 349-50 per Dawson J, at 357 per McHugh J (Mason CJ and Brennan and Gaudron JJ agreeing at 334); Commissioner of Taxation v SNF (Australia) Pty Ltd [2011] FCAFC 74; 193 FCR 149 at 183 [107] and 184 [114]; Bywater Investments Limited v Commissioner of Taxation [2016] HCA 45; 260 CLR 169 at 228 [167] per Gordon J.
26 Article 4 of the Model Tax Convention is in substantially the same terms as Art 4(3)(c) of the Double Tax Agreement, save that the order of the cascading provisions in the tiebreaker test is different. Art 4 of the Model Tax Convention, as it was in the 2009 to 2014 years, was in the following terms:
RESIDENT
1. For the purposes of this Convention, the term "resident of a Contracting State" means any person who, under the laws of that State, is liable to tax therein by reason of his domicile, residence, place of management or any other criterion of a similar nature, and also includes that State and any political subdivision or local authority thereof. This term, however, does not include any person who is liable to tax in that State in respect only of income from sources in that State or capital situated therein.
2. Where by reason of the provisions of paragraph 1 an individual is a resident of both Contracting States, then his status shall be determined as follows:
(a) he shall be deemed to be a resident only of the State in which he has a permanent home available to him; if he has a permanent home available to him in both States, he shall be deemed to be a resident only of the State with which his personal and economic relations are closer (centre of vital interests);
(b) if the State in which he has his centre of vital interests cannot be determined, or if he has not a permanent home available to him in either State, he shall be deemed to be a resident only of the State in which he has an habitual abode;
(c) if he has an habitual abode in both States or in neither of them, he shall be deemed to be a resident only of the State of which he is a national;
(d) if he is a national of both States or neither of them, the competent authorities of the Contracting States shall settle the question by mutual agreement.
3. Where by reason of the provisions of paragraph 1 a person other than an individual is a resident of both Contracting States, then it shall be deemed to be a resident only of the State in which its place of effective management is situated.
27 There has been a subsequent change to the drafting of Art 4(3) of the Model Tax Convention but that change is not material in this context.
28 The OECD commentary includes a chapter on Art 4. The 2017 version of the commentary to which the primary judge referred was not the commentary as it was at the time that the Double Tax Agreement entered into force in Australian law. It is, however, unnecessary in this case to resolve a question as to whether a later commentary can be relied on to assist in the construction of a double tax agreement (Burton v Federal Commissioner of Taxation [2019] FCAFC 141; 271 FCR 548 at 579-80 [124] per Steward J) as [19] of the 1977 OECD commentary on Art 4, which was the commentary in place at the time the Double Tax Agreement was entered into, was not in materially different terms to the 2017 version of the OECD commentary. Critically, it did not provide that a person's habitual abode is the place in which the person spends the most time. Paragraph 19 of the 1977 version provided:
In stipulating that in the two situations which it contemplates preference is given to the Contracting State where the individual has an habitual abode, sub-paragraph b) does not specify over what length of time the comparison must be made. The comparison must cover a sufficient length of time for it to be possible to determine whether the residence in each of the two States is habitual and to determine also the intervals at which the stays take place.
29 Applying the interpretative principles that are applicable to the construction of Art 4 of the Double Tax Agreement, there is no warrant, in our opinion, for imputing that the habitual abode of a person is the place where the individual has spent more days. The primary judge in our view correctly rejected that argument at [99].
30 First, that is not the language of Art 4(3)(b) and there is no warrant to give the expression "habitual abode", which is not defined for the purposes of Art 4(3)(b) of the Double Tax Agreement nor Art 4 of the Model Tax Convention, a meaning other than the meaning conveyed by the ordinary meaning of the phrase. Mr Pike placed reliance on the OECD glossary of tax terms, which does contain a definition of "habitual abode" that suggests that it "refers to the period of time a taxpayer spends in each country". But that glossary does not assist Mr Pike as it does not form part of the OECD commentary and, more particularly, the glossary is specifically headed by a disclaimer in the following terms:
Disclaimer: Explanations on the terms are very condensed and may not be complete. They are not considered to necessarily reflect official position of the OECD in interpreting international tax terms, for example, in the tax treaty context.
31 Secondly, none of the versions of the OECD commentary explain Art 4(3)(b) of the Model Tax Convention as operating in the way Mr Pike contends. The example given in [19] of the 2017 OECD commentary on Art 4 to which Mr Pike referred does not support the contention that the place of habitual abode is the State where the taxpayer spends the most time.
32 Thirdly, the substantive difference between Art 4(3) of the Double Tax Agreement and its cognate in the Model Tax Convention is the order in which the tests operate. In particular, the Double Tax Agreement provides that the permanent home test is the first tiebreaker test. The Double Tax Agreement then uses the habitual abode test as the second tiebreaker test and the personal and economic relations test is the third test, whereas the Model Tax Convention uses the second and third tests in the opposite order. The Model Tax Convention also contains additional steps in the tiebreaker test that are not adopted in the Double Tax Agreement. We discern no particular significance arising from that order nor from the additional steps for the purposes of the construction and application of Art 4(3)(b) of the Double Tax Agreement in this case. Nor did either party suggest any particular significance.
33 We agree with and adopt the reasons of the primary judge for concluding that during the relevant years Mr Pike had an habitual abode in both countries. No error is discernible in his Honour's reasoning or conclusion.
34 That leaves the application of the "personal and economic relations" test in Art 4(3)(c) of the Double Tax Agreement. The primary judge at [104] held that "when considered conjunctively", Mr Pike's personal and economic relations were closer to Thailand than Australia between 2009 and 2014. The Commissioner did not cavil that Art 4(3)(c) involves a conjunctive test. Indeed, the Commissioner accepted that the primary judge correctly observed that Mr Pike's "personal and economic relations" had to be considered conjunctively. However, it was submitted, in applying that test the primary judge fell into error by applying the test disjunctively. It was argued that rather than considering whether Mr Pike's "personal and economic relations", taken together, were closer to Australia or Thailand, the primary judge considered first whether Mr Pike's personal relations were closer to Australia or Thailand and secondly, as a separate and independent consideration, whether Mr Pike's economic relations were closer to Australia or Thailand. So much was said to be apparent from the reasons at [101]-[102] where his Honour stated:
On the evidence, Mr Pike undoubtedly had a range of personal relations while he resided in Thailand. He formed particular friendships and actively engaged in various sporting and social activities there. As Ms Thornicroft neatly put it, "He had a life there." He was hardly there a mere fly in/fly out worker eating and sleeping at a work camp with no wider community life. However, at an emotional level, his closer personal relations were, undoubtedly, with Ms Thornicroft and their sons in Australia. In contrast and overwhelmingly, Mr Pike's economic relations were closer to Thailand. It was this Thai sourced income stream, derived from Mr Pike's ongoing employment there, which not only supported his life and lifestyle there but also, all the more so after Ms Thornicroft's employment with Ernst & Young came to an end, supported his family in Australia, including him, when he was able to be with them. Contrary to his original aspiration, Mr Pike had never been employed in Australia. There is not even any evidence that the group of which PTAL was a member was controlled from Australia. His journeys here were wholly personal, never in the additional nature of reporting in person to, or working for a time at, a "head office" or even controlling regional office.
For part of the period between 2010 and 2013, Mr Pike owned a capital asset in Australia, the Brookwater land. While I accept that this land can, on the basis of ownership alone, be regarded as evidencing an economic relationship with Australia, it did not have the additional feature of being a competitor of any sort with the Thai employment for income production. Mr Pike maintained bank accounts in both Thailand and Australia but these were but conduits through which living and other expenses in Thailand or Australia for him or, as the case may be, him and his family were met. Mr Pike jointly owned cars in Australia but, even taken in conjunction with the Brookwater land, as a foundation for relative closeness of economic relations, these pale into relative insignificance when compared with Mr Pike's Thai employment.
35 Further, it was submitted that irrespective of whether the primary judge applied the correct test, the primary judge erred in not finding that Mr Pike's personal and economic relations were closer to Australia. Relevant findings said to support that conclusion were said to be as follows:
(a) that Mr Pike was "devoted" to his family and had "enduring ties of love and affection for his wife and sons" and returned to Australia "to live with his family as often and for as long as possible" (primary judgment at [61] and [62]);
(b) that "[a]ll throughout the lengthy periods of work-related separation from Mr Pike, [Ms Thornicroft] remained committed to their relationship and regarded, for good reason, Mr Pike as similarly committed with the premises rented in Brisbane from time to time being regarded as their family home" (primary judgment at [32]);
(c) that the "true position" was revealed by the following exchange with Ms Thornicroft during cross-examination (primary judgment at [32]):
And in terms of that, you would agree with me that the most important thing between you and Mr Pike throughout the whole of your relationship has been the importance of family? --- Yes. The children, yes.
The children and you? --- Yes.
(d) that "[w]hen returning to Australia, Mr Pike has always returned to the home where Ms Thornicroft and their sons were for the time being located. He has always regarded this as the family home. Over the years, his returns to Australia have coincided with family occasions, such as birthdays, Christmas and school prize giving and have also been occasioned by family emergencies" (primary judgment at [43]);
(e) that "[w]hen Mr Pike returned to Australia he was not, as his submissions invited [the primary judge] to conclude, a resident of Thailand, Tanzania or, as the case may be, Dubai in the UAE, returning as a visitor to Australia. Rather, he returned as husband (de facto) and father to resume living - residing - with his wife and children at the family home. It was not just their family home; it was his also;" (emphasis in original) (primary judgment at [60]);
(f) that Ms Thornicroft and "Mr Pike had aspired to [obtain Australian citizenship] for themselves and their sons ever since relocating to Australia in 2005" (primary judgment at [25]);
(g) that in support of Mr Pike's application for Australian citizenship, Ms Thornicroft had written a letter which stated "Australia and more so Brisbane is our family home. [Mr Pike] returns home regularly and is truly invested in our lives here" (primary judgment at [29]);
(h) that Mr Pike "regularly transferred funds to [his joint account in Australia] to support Ms Thornicroft and their sons," that shortly after Mr Pike moved to Australia from Zimbabwe he "obtained a credit card with an Australian bank" and that Mr Pike jointly owned cars in Australia (primary judgment at [21] and [102]);
(i) that "[i]n September 2010, Mr Pike and Ms Thornicroft… purchased vacant land at Brookwater… a residential golf community in Ipswich, Queensland. Their intention was not only to build a family home on that land but also to provide something tangible in Australia for their sons" (primary judgment at [24]).
36 Additionally, it was argued the acquisition of Brookwater land soon after Ms Thornicroft and the couple's sons obtained Australian citizenship reflected both an economic and personal relation to Australia for Mr Pike. Reference was made to Mr Pike's evidence in cross-examination that citizenship was a "game changer" because, compared to the "volatile situation" in Zimbabwe, he and Ms Thornicroft could put their name against a piece of property which they could hand to their children. It was submitted that given Mr Pike had always held the "wish", since arriving in Australia in 2005, that he and his family would all become Australian citizens, the acquisition of the Brookwater land in 2010, following Ms Thornicroft being granted citizenship, was confirmation of Mr Pike's desire for close personal and economic relations with Australia. It was also argued that the fact that Mr Pike's personal and economic relations were closer to Australia than Thailand was reflected by the fact that consideration was given to Ms Thornicroft and their sons joining him to live in Thailand, but this was rejected as both he and Ms Thornicroft decided it was in the best interests of the family for the family to remain in Australia. By contrast, the argument went, Mr Pike's personal and economic relations with Thailand were found to be centred on his employment there, social contacts he had made through sport and the establishment of a bank account in Thailand.
37 Finally, it was submitted that the findings and the evidence reflected that Mr Pike had an enduring and permanent connection to Australia that persisted irrespective of changes in employment. In contrast, the connection to Thailand existed only while work was available. In this context, it was submitted, the primary judge's finding that Mr Pike's personal relations were "undoubtedly" closer to Australia, and not Thailand, should have led him to conclude that Mr Pike's "personal and economic relations" were closer to Australia. Reliance was placed on [15] of the OECD commentary on Art 4, which has been unchanged since the 1977 version of the OECD commentary and which states that "it is nevertheless obvious that considerations based on the personal acts of the individual must receive special attention", and on the New Zealand Taxation Review Authority decision in FFF v Commissioner of Inland Revenue [2011] NZTRA 8 (FFF) in which the authority observed at [62] that:
If the economic factor is closer to one place and the personal factor closer to another, it will be resolved by which of the two localities is of greater significance to the taxpayer.
38 We reject both the contention that the primary judge applied a disjunctive test, not a conjunctive test, and the contention that the findings of facts should have led the primary judge to conclude that Mr Pike's personal and economic relations were closer to Australia.
39 First, no error is discernible in the approach of the primary judge in examining Mr Pike's personal and economic considerations. Each case must be fact specific. In some cases the personal and economic considerations may be so intertwined that they are not separate considerations, whereas in other cases, they may be quite separate and distinct matters. Further, and contrary to the New Zealand decision in FFF, the clause does not place greater weight on personal factors over economic factors. As the parties agreed, Art 4(3)(c) poses a composite test and in each case it will be a matter of fact and degree as to whether a taxpayer's personal and economic relations, viewed as a whole, support ties closer to one contracting state over the other contracting state. The primary judge correctly looked at Mr Pike's overall circumstances and engaged in a balancing of the significance of those personal and economic considerations as supporting ties closer to one contracting state than the other.
40 Secondly, it was not put that the primary judge failed to make any necessary finding of fact, nor that the primary judge made any wrong findings of fact on which his Honour based his conclusion that Mr Pike's personal and economic relations were closer to Thailand, nor that the primary judge took irrelevant considerations into account or failed to take relevant considerations into account. Rather, the Commissioner's case, in substance, rested on the weight which the primary judge attributed to some of the facts. Critically, in that regard, the primary judge expressly considered, and was of the view, that Mr Pike's personal relations were closer to Australia than Thailand.
41 Thirdly, an evaluation of the facts does not persuade us that the conclusion of the primary judge was wrong: Warren v Coombes [1979] HCA 9; 142 CLR 531 at 551 per Gibbs ACJ, Jacobs and Murphy JJ; Branir Pty Ltd v Owston Nominees (No 2) Pty Ltd [2001] FCA 1833; 117 FCR 424 at 437-8 [28]-[29] per Allsop J; Minister for Immigration and Border Protection v SZVFW [2018] HCA 30; 264 CLR 541 at 559-63 [40]-[49] per Gageler J; Commissioner of Taxation v Scone Race Club Limited [2019] FCAFC 225; 374 ALR 189 at 198-9 [46] per Griffiths J. An appeal court will not overturn the decision of the primary judge merely because it prefers an outcome different from that adopted by the primary judge where both outcomes are equally available or finely balanced. In our view, this is such a case as the findings of fact upon which the Commissioner rested his case do not compel a different conclusion. Nor can it be said that the conclusion reached by the primary judge was not reasonably open.
