The third ground of appeal
31 The third ground of appeal raises the question of the operation of s 88F and s 88G(1) of the Marriage Act, which are within Part VA of the Act relating to the recognition of foreign marriages.
32 At common law, upon proof that a marriage ceremony was duly performed, a presumption arises in favour of the validity of the marriage, casting upon those who deny the validity of a marriage the burden of producing reasonable evidence of a fact that renders the marriage void: Axon v Axon [1937] HCA 80; 59 CLR 395 at 403-404 (Dixon J). That presumption extends to marriages in foreign places and under foreign law: Jacombe v Jacombe [1961] HCA 25; 105 CLR 355 at 359-360 (Dixon CJ, Fullagar and Menzies JJ).
33 Part VA of the Marriage Act was inserted by the Marriage Amendment Act 1985 (Cth). Section 88A provides that the object of the Part is to give effect to Chapter II of the Convention on Celebration and Recognition of the Validity of Marriages [1991] ATS 16, done at The Hague on 14 March 1978, and which was signed by Australia on 9 July 1980. Articles 9 to 12 of the Convention correspond to the provisions of the Marriage Act in issue in the present appeal -
Article 9
A marriage validly entered into under the law of the State of celebration or which subsequently becomes valid under that law shall be considered as such in all Contracting States, subject to the provisions of this Chapter.
A marriage celebrated by a diplomatic agent or consular official in accordance with his law shall similarly be considered valid in all Contracting States, provided that the celebration is not prohibited by the State of celebration.
Article 10
Where a marriage certificate has been issued by a competent authority, the marriage shall be presumed to be valid until the contrary is established.
Article 11
A Contracting State may refuse to recognise the validity of a marriage only where, at the time of the marriage, under the law of that State -
(1) one of the spouses was already married; or
(2) the spouses were related to one another, by blood or by adoption, in the direct line or as brother and sister; or
(3) one of the spouses had not attained the minimum age required for marriage, nor had obtained the necessary dispensation; or
(4) one of the spouses did not have the mental capacity to consent; or
(5) one of the spouses did not freely consent to the marriage.
However, recognition may not be refused where, in the case mentioned in sub-paragraph 1 of the preceding paragraph, the marriage has subsequently become valid by reason of the dissolution or annulment of the prior marriage.
Article 12
The rules of this Chapter shall apply even where the recognition of the validity of a marriage is to be dealt with as an incidental question in the context of another question.
However, these rules need not be applied where that other question, under the choice of law rules of the forum, is governed by the law of a non-Contracting State.
34 Before the primary judge, the appellant relied on s 88F and s 88G of the Marriage Act, which provide -
88F Incidental determination of recognition of certain foreign marriages
Notwithstanding any other law, the question whether a marriage solemnised in a foreign country is to be recognised in Australia as valid shall be determined in accordance with the provisions of this Part, whether or not the determination of the question is incidental to the determination of another question.
88G Evidence
(1) A document purporting to be either the original or a certified copy of a certificate, entry or record of a marriage alleged to have been solemnised in, or under the law of, a foreign country and purporting to have been issued by:
(a) in the case of a marriage alleged to have been solemnised in a foreign country - an authority of that country or of that part of the country in which the marriage was allegedly solemnised; or
(b) in the case of a marriage alleged to have been solemnised under the law of a foreign country - an authority of that country;
is, for all purposes, prima facie evidence of the facts stated in the document and of the validity of the marriage to which the document relates.
…
35 The explanatory memorandum to the Marriage Amendment Bill 1985 stated that s 88F was in accordance with the basic policy expressed in Article 12 of the Convention, which is set out under [33] above. Section 88F is directed to a situation where the question of the validity of a marriage may be incidental to some other question, such as the right to share in an estate under the laws of succession, or a right to statutory compensation where marriage is a criterion, as illustrated by Haque v Haque [1962] HCA 39; 108 CLR 230. The issue that may arise is whether the question of the validity of a marriage is to be determined in accordance with the choice of law rules relating to the underlying cause of action in question, or in accordance with choice of law rules that are specifically applicable to the question of marriage. Some of these questions are referred to in Collins (Ed), Dicey and Morris on The Conflict of Laws (13th ed, 2000) in Chapter 2. See also, Gotlieb, The Incidental Question in Anglo-American Conflict of Laws (1955) 33 Can Bar Rev 523; Gotlieb, The Incidental Question Revisited - Theory and Practice in the Conflict of Laws (1977) 26 ICLQ 734; Fisher, The Australian Adoption of The Hague Convention on Celebration and Recognition of the Validity of Marriages (1986) 2 QITLJ 17; Davies, Bell, Brereton and Douglas, Nygh's Conflict of Laws in Australia (10th ed, 2020) at [15.28] to [15.34].
36 The effect of s 88G(1) of the Marriage Act is that a document purporting to be a record of a marriage alleged to have been solemnised under the law of a foreign country is for all purposes prima facie evidence of the facts stated in the document, and of the validity of the marriage. Section 88G may be compared to s 102 of the Family Law Act 1975 (Cth), which is less prescriptive in its terms, and applies only to proceedings under that Act.
37 Attention must also be directed to s 88C and to s 88D of the Marriage Act, which provide (inter alia) -
88C Application of this Part
(1) This Part applies to and in relation to every marriage solemnised, whether before or after the commencement of this Part, in a foreign country where:
(a) under the local law, the marriage was, at the time when it was solemnised, recognised as valid; or
(b) if the marriage was solemnised by or in the presence of a diplomatic or consular officer of another foreign country:
(i) under the law of that other foreign country, the marriage was, at the time when it was solemnised, recognised as valid; and
(ii) at the time when it was solemnised, the solemnisation of the marriage was not prohibited by the local law.
(2) Where a marriage (not being a marriage referred to in subsection (1)) that was solemnised, whether before or after the commencement of this Part, in a foreign country:
(a) is, at any time in relation to which the validity of the marriage falls to be determined, recognised as valid under the local law; or
(b) if the marriage was solemnised by or in the presence of a diplomatic or consular officer of another foreign country and, at the time when it was solemnised, the solemnisation of the marriage was not prohibited by the local law - is, at any time in relation to which the validity of the marriage falls to be determined, recognised as valid under the law of that other foreign country;
this Part applies to and in relation to the marriage from and including that time.
88D Validity of marriages
(1) Subject to this section, a marriage to which this Part applies shall be recognised in Australia as valid.
(2) A marriage to which this Part applies shall not be recognised as valid in accordance with subsection (1) if:
…
(c) the parties are within a prohibited relationship within the meaning of section 23B; or
…
…
38 Section 88D(2)(c), set out above, refers to s 23B(2) of the Marriage Act, which provides -
23B Grounds on which marriages are void
…
(2) Marriages of parties within a prohibited relationship are marriages:
(a) between a person and an ancestor or descendant of the person; or
(b) between a brother and a sister (whether of the whole blood or the half-blood).
…
39 It is relevant to an understanding of ss 88C, 88D, 88F, and s 88G(1) of the Marriage Act to have regard to the interpretation provision in s 88B(3) -
88B Interpretation
(1) In this Part, unless the contrary intention appears:
…
local law, in relation to a marriage solemnised in a foreign country, means the law in force in the foreign country or in that part of the foreign country in which the marriage was solemnised.
…
(3) In this Part, a reference to a marriage includes a reference to a purported marriage that is void or voidable but does not include a reference to a marriage solemnised under Part V.
…
40 Before the primary judge, counsel for the appellant submitted that the Tribunal had failed to recognise that s 88F and s 88G of the Marriage Act required that the appellant's marriage to the visa applicant be prima facie recognised as being valid because the marriage was evidenced by a marriage certificate. Counsel submitted that in this context the 2012 DNA test results had been given improper weight.
41 The primary judge rejected the appellant's claim, holding at [54] that while the marriage was prima facie valid, the provisions of s 88D and s 23B(2) prevailed. On appeal, counsel for the appellant submitted that the primary judge had erred, and that s 88D was concerned only with facts that might be proven to rebut a presumption established by s 88G(1).
42 The submissions advanced on behalf of the appellant raise two main issues: (1) as a question of construction, is the prima facie position established by s 88G(1) of the Act concerned with the validity of a marriage under foreign law, or does it extend to the recognition in Australia of the validity of a marriage for the purposes of s 88D of the Act; and (2) in any event, what is the effect of the prima facie position established by s 88G(1)?
43 The explanatory memorandum to the Marriage Amendment Bill 1985 stated that s 88G was in accordance with Article 10 of the Convention. Article 10 must be read subject to Article 11, which permits a Contracting State to refuse to recognise the validity of a marriage in circumstances that align with s 88D(2) of the Marriage Act. Therefore, consistently with Articles 9 to 12 of the Convention, which are set out under [33] above, the scheme of Part VA of the Marriage Act differentiates between the validity of a marriage under foreign law, and the recognition of the validity of the marriage under Australian law. The combined effect of s 88C and s 88D is that a marriage that is valid under foreign law shall be recognised in Australia as valid, unless one of the exceptions in sub-ss 88D(2) to (5) is engaged. In order for Part VA of the Act to apply, there is the requirement in s 88C(1)(a) that a marriage solemnised in a foreign country be recognised as valid under the applicable local law. Section 88C(2) extends the application of Part VA to marriages solemnised in a foreign country that are recognised as valid under the local law at any time in relation to which the validity of the marriage falls to be determined.
44 As I have indicated, s 88D of the Marriage Act is concerned with the question of recognition in Australia of the validity of a marriage, and sub-ss 88D(2) to (5) provide for exceptions to the general rule in s 88D(1) that a marriage to which Part VA applies shall be recognised in Australia as being valid. Section 88D contains its own criteria relating to the question of recognition under Australian law. In simple terms, those criteria are that the marriage is one to which Part VA applies, and is not one to which any of the disqualifying conditions in sub-ss 88D(2) to (5) applies.
45 In my view, the better construction of s 88G(1) of the Marriage Act is that it is concerned with the fact of, and the validity of a marriage under foreign law: it is not directly concerned with the recognition of a marriage for the purposes of s 88D. That construction is supported by the text of s 88G(1), which provides that a document to which the provision applies is prima facie evidence of the validity of the marriage to which the document relates, which complements s 88C(1) of the Act, by facilitating proof of the fact of, and the validity of the marriage in a foreign country. It is also consistent with the delineation between the validity of a marriage under the law applicable to the solemnisation of the marriage, and the recognition of a marriage, which is subject to the laws of the forum, being Australia. The validity of a marriage under foreign law is a question that is relevant to whether Part VA of the Act applies, and is anterior to the question of recognition under Australian law pursuant to s 88D. It is unlikely that a document recording a foreign marriage that was issued by a competent authority in relation to a foreign country would speak to the validity of a marriage for the purposes of recognition under the laws of Australia, and in particular to the exclusions in sub-ss 88D(2) to (5) of the Marriage Act. This construction has the consequence that in proceedings where there are pleadings and where the rules of evidence apply, a party seeking to invoke one of the exclusions in sub-ss 88D(2) to (5) of the Marriage Act would ordinarily have to raise the issue and adduce evidence, following which a court would evaluate the totality of the evidence having regard to the identification of which party bears the legal burden of proof, and the gravity of the underlying matters alleged: Evidence Act 1995 (Cth), s 142(2). In criminal proceedings, an onus may fall upon the Crown to exclude the exceptions in sub-ss 88D(2) to (5): cf, R v Byast [1997] QCA 276; [1999] 2 Qd R 384 at 386.
46 For these reasons, I consider that the evidentiary provision in s 88G(1) of the Marriage Act was not applicable to the contentious question whether, for the purposes of s 88D of the Act, the appellant and the visa applicant were half-siblings, with the consequences that they were in a prohibited relationship within the meaning of s 23B of the Act. The primary judge was therefore correct in holding at [54] of her Honour's reasons for judgment that s 88D of the Act prevailed.
47 The appellant's argument assumed that s 88G(1) otherwise applied to a review by the Tribunal. I raised this assumption with counsel during the course of the hearing, but it was not the subject of full argument. The Tribunal was not bound by technicalities, legal forms, or rules of evidence, and was required to act according to substantial justice and the merits of the case: Migration Act, s 353. However, s 88G(1) of the Marriage Act provides that a document to which it applies is, "for all purposes", prima facie evidence of the facts stated in the document and of the validity of the marriage. The assumption that s 88G(1) applied to a review by the Tribunal may be supported, as counsel for the appellant submitted in response to a question from the court during the hearing, by construing s 12 of the Migration Act, which provides that Part VA of the Marriage Act applies for the purpose of recognising whether a marriage is to be recognised as valid, as making s 88G(1) of the Marriage Act applicable to all decisions under the Migration Act, whether administrative or curial. In addition, s 88G(1) of the Marriage Act and s 353 of the Migration Act may be reconciled by giving literal effect to the term "for all purposes" in s 88G(1), thereby suppressing the general operation of s 353 of the Migration Act on the ground that it is of general operation, whereas s 88G of the Marriage Act, as picked up by s 12 of the Migration Act, has a specific operation relating to proof of marriage. Another approach might be to treat s 88G(1) of the Marriage Act as a rule of substantive law, consistently with its origins as an implementation of a Convention obligation, so that it applies to an administrative decision-maker such as the Tribunal, which in any event was required to act according to substantial justice and the merits of the case. Counsel for the Minister accepted during argument that in acting according to substantial justice and the merits of the case the Tribunal would ordinarily be expected to give effect to s 88G(1) of the Marriage Act.
48 Alternatively, if I am wrong in my construction of s 88G(1), then even if the Tribunal was required to treat the marriage certificate as prima facie evidence of the validity of the marriage for the purposes of recognition under s 88D, then there was no material error in the Tribunal placing significant weight on the 2012 DNA test results and no weight on the marriage certificate.
49 To say that a document is prima facie evidence of a fact or state of affairs raises a presumption that may be rebutted. In the absence of other material, a decision-maker may act on the document. However, where there is other evidence that directly addresses the fact in issue, a prima facie presumption may lose much of its force: see for example, and in a curial context, Saxe v Kellett [1970] VR 600 at 602 (Anderson J).
50 The contentious question that the Tribunal determined adversely to the appellant and the visa applicant was not whether a marriage ceremony had taken place, or the validity of the marriage under the local law of Ethiopia. The contentious issue before the Tribunal was whether it was satisfied that the appellant's marriage was recognised in Australia as a valid marriage having regard to the 2012 DNA test results that supported a conclusion that the appellant and the visa applicant were half-siblings. The appellant's marriage certificate did not speak to that issue at all, and from an evidentiary viewpoint on that question it was an empty husk because there was nothing of substance in the marriage certificate to balance against the evidence of the 2012 DNA results, which it was open to the Tribunal to accept as having significant weight. For this reason, any error by the Tribunal in failing to have regard to s 88G(1) of the Marriage Act as giving rise to a prima facie presumption of recognition of validity for the purposes of s 88D was not material, because there was no realistic possibility of a different outcome having regard to the other evidence that the Tribunal accepted: Minister for Immigration and Border Protection v SZMTA [2019] HCA 3; 264 CLR 421 at [45], [48]-[50], [70]-[71] (Bell, Gageler and Keane JJ).
