Wilkinson v Kitzinger & Ors

Factual and Procedural Background

The Petitioner seeks a declaration regarding her marital status under section 55 of the Family Law Act 1986. On 26 August 2003, the Petitioner and the first Respondent, both domiciled in England, entered into a marriage ceremony in British Columbia, Canada, which permits and recognises same-sex marriages. Prior to this, they had cohabited as a couple for thirteen years. Upon returning to the United Kingdom and before the Civil Partnership Act 2004 came into force, the Petitioner initiated proceedings seeking recognition that their Canadian marriage was valid under English law. She also sought, if necessary, a declaration of incompatibility under section 4 of the Human Rights Act 1998 concerning section 11(c) of the Matrimonial Causes Act 1973.

The Petitioner and the first Respondent, both university professors, provided witness statements detailing the history and significance of their relationship and marriage. They expressed that recognition of their marriage as a civil partnership rather than a marriage was offensive and demeaning, emphasizing the social and legal importance of marriage as a fundamental institution.

The Petitioner relies on Canadian legal expert reports establishing the validity of the marriage under Canadian law. The case involves consideration of English common law and statutory definitions of marriage, the Civil Partnership Act 2004, and relevant provisions of the European Convention on Human Rights as incorporated by the Human Rights Act 1998.

Legal Issues Presented

1. Whether the Canadian same-sex marriage is valid and recognised as a marriage under the law of England and Wales.
2. Whether the statutory provisions in the Matrimonial Causes Act 1973 and the Civil Partnership Act 2004, which preclude recognition of same-sex marriages as marriages, are compatible with the Petitioner’s Convention rights under Articles 8, 12, and 14 of the European Convention on Human Rights.
3. Whether the court can interpret or develop the law, including private international law rules, to recognise same-sex marriages despite statutory provisions to the contrary.
4. Whether, alternatively, a declaration of incompatibility under section 4 of the Human Rights Act 1998 should be made concerning the statutory provisions.

Arguments of the Parties

Petitioner's Arguments

• The statutory provisions excluding same-sex marriages from recognition as marriages violate the Petitioner’s rights under Articles 8 (right to respect for private and family life), 12 (right to marry), and 14 (prohibition of discrimination) of the European Convention on Human Rights.
• The court should interpret section 11(c) of the Matrimonial Causes Act 1973 and relevant provisions of the Civil Partnership Act 2004 compatibly with Convention rights under section 3 of the Human Rights Act 1998, thereby recognising same-sex marriages lawfully entered abroad as valid marriages in English law.
• Alternatively, the court should develop the common law to recognise the Petitioner’s Canadian marriage as valid in English law, including modifying private international law rules on capacity to marry based on domicile.
• Alternatively, the court should make a declaration of incompatibility under section 4 of the Human Rights Act 1998 concerning the statutory provisions.
• The difference in treatment between same-sex and opposite-sex couples regarding the status and title of marriage causes feelings of vulnerability, humiliation, and anxiety, amounting to discrimination within the ambit of the Convention rights.
• Canadian and South African jurisprudence support recognition of same-sex marriage as a matter of equality and human rights.

Intervener's Arguments

• The statutory provisions are clear and compatible with the Petitioner’s Convention rights; no breach arises from the refusal to recognise same-sex marriage as marriage under English law.
• Interpretation or "reading down" of the statutory provisions to recognise same-sex marriage is not possible; relief is limited to a declaration of incompatibility if any breach were found.
• Recognition of marriage as a union between a man and a woman does not violate Articles 8 or 12 as currently interpreted by the European Court of Human Rights.
• The Civil Partnership Act 2004 provides an equalising measure that confers rights equivalent to marriage for same-sex couples, and any discrimination in title or status is justified and within the margin of appreciation accorded to States.
• There is no scope for modifying private international law rules to circumvent clear statutory provisions.

Court's Reasoning and Analysis

The court began by confirming the established common law and statutory definition of marriage as a voluntary union for life between one man and one woman, as affirmed by longstanding case law and statutory provisions, particularly section 11(c) of the Matrimonial Causes Act 1973. The Civil Partnership Act 2004 was recognized as a legislative response providing same-sex couples with rights and responsibilities equivalent to marriage, but deliberately excluding the status and title of marriage itself.

The court reviewed the relevant European Convention on Human Rights provisions, focusing on Articles 8, 12, and 14, and the interpretative obligations under the Human Rights Act 1998. It noted that the European Court of Human Rights has consistently allowed a wide margin of appreciation to States in matters of social, political, and religious controversy, including the recognition of same-sex relationships.

Regarding Article 12, the court found that the right to marry traditionally applies to opposite-sex couples and that the Goodwin decision, while broadening the understanding of gender, did not extend the right to marry to same-sex couples. The court held that the "living instrument" doctrine does not permit extending Article 12 to encompass same-sex marriage absent a clear European consensus.

In relation to Article 8, the court acknowledged that private life is broad and includes intimate relationships but emphasized that current Strasbourg jurisprudence does not recognize childless same-sex couples as constituting family life under Article 8. The court found no state interference with the Petitioner’s private or family life rights, as the Civil Partnership Act provides equivalent legal protections.

On Article 14, the court accepted that the Petitioner’s situation falls within the ambit of Articles 8 and 12 but concluded that the difference in treatment between same-sex and opposite-sex couples is justified. The court found that the institution of marriage as between opposite sexes has a legitimate aim related to social stability and child-rearing, and that the Civil Partnership Act’s approach is a proportionate means of addressing inequality without altering the traditional concept of marriage.

The court rejected the Petitioner’s submissions to reinterpret or develop the common law or private international law to recognise same-sex marriages, noting that such judicial law-making would conflict with clear statutory provisions and public policy considerations. It also distinguished foreign jurisprudence from Canada and South Africa due to differing legal frameworks and constitutional mandates.

Holding and Implications

The court’s final decision is to DISMISS the Petitioner’s petition seeking recognition of the Canadian same-sex marriage as valid under English law.

The direct effect is that the Petitioner’s marriage remains unrecognised as a marriage in England and Wales, being treated instead as a civil partnership under the Civil Partnership Act 2004. The court upheld the legislative distinction between marriage and civil partnership and affirmed the margin of appreciation accorded to Parliament in this sensitive social area.

No new legal precedent was established beyond affirming existing law and Strasbourg jurisprudence. The decision reinforces that changes to the legal definition of marriage to include same-sex couples are matters for legislative, not judicial, determination.
