KB and Another v Minister of Social Development and Others

Case Summary: KB and Another v Minister of Social Development and Others

1. Introduction

Surrogacy forms part of the broader framework of assisted reproductive technologies and raises complex legal, ethical, and constitutional questions, particularly concerning the regulation of parenthood, genetics, and the best interests of the child. In South Africa, surrogacy arrangements are primarily governed by Chapter 19 of the Children’s Act 38 of 2005, which sets out strict requirements for the validity of surrogate motherhood agreements. One such requirement, contained in section 294, mandates that at least one commissioning parent must contribute genetic material to the child born through surrogacy.
The case of KB and Another v Minister of Social Development and Others revisits the constitutionality of section 294 of the Children’s Act. The appellants, a married couple who had previously become parents through artificial fertilisation using donor gametes, sought to challenge the genetic link requirement on constitutional grounds. They argued that the provision unjustifiably infringed the rights of their existing minor child and prevented them from expanding their family through surrogacy. The case required the court to consider constitutional rights, the doctrine of precedent, and the limits of judicial intervention within a constitutional democracy.

3. Court and Bench

The matter was heard by the Constitutional Court of South Africa, sitting as a full Constitutional Court bench.

4. Date of Judgment

The judgment was delivered in 2023.

5. Parties to the Dispute

The appellants were KB and HBB, a married heterosexual couple.

The respondents included the Minister of Social Development and other relevant state parties responsible for the administration and enforcement of the Children’s Act.

6. Factual Background

KB and HBB were married in December 2011. During their marriage, the couple experienced significant fertility challenges and were unable to conceive a child naturally. They pursued several forms of assisted reproductive treatment, including intrauterine insemination and in vitro fertilisation, but these attempts were unsuccessful. Eventually, the couple opted for artificial fertilisation using donor gametes that were not genetically linked to either of them.

As a result of this procedure, KB gave birth to a son on 21 February 2018. Despite the absence of a genetic link between the child and the appellants, the child is regarded, for all legal purposes, as their biological child in terms of section 40 of the Children’s Act 38 of 2005. This provision establishes that a child born through artificial fertilisation is legally considered the child of the woman who gives birth and her spouse or partner, provided there is consent.

The appellants subsequently expressed a desire to have another child. Given their continued fertility challenges, they believed that surrogacy was the only viable option available to them. They identified a willing surrogate mother and drafted a surrogacy agreement. However, in terms of South African law, such an agreement requires confirmation by a court before it can be executed.

The appellants’ proposed surrogacy arrangement did not meet the requirements of section 294 of the Children’s Act, as neither commissioning parent would contribute genetic material to the child. Consequently, they approached the court seeking an order declaring section 294 constitutionally invalid or, alternatively, requesting that specific words be read into the provision to permit a surrogacy arrangement where no genetic link exists between the commissioning parents and the child.

7. Issues Before the Court

The court was required to determine the following key issues:

1. Whether section 294 of the Children’s Act is constitutionally invalid.
2. Whether section 294 unjustifiably infringes the rights of the appellants’ existing minor child, particularly the child’s best interests under section 28(2) of the Constitution.
3. Whether the court was entitled to depart from or reconsider the Constitutional Court’s earlier decision in AB and Another v Minister of Social Development.
4. Whether a reading-in remedy was appropriate if constitutional invalidity were established.

8. Legal Framework

Section 294 of the Children’s Act requires that a surrogate motherhood agreement must include the condition that the child to be born will be genetically related to at least one of the commissioning parents. This provision reflects a legislative policy choice aimed at regulating surrogacy strictly, preventing commodification, and ensuring a clear connection between the child and the commissioning family.

The appellants grounded their constitutional challenge primarily on section 28(2) of the Constitution, which provides that the best interests of the child are of paramount importance in every matter concerning the child. They further relied on the rights to equality and dignity under sections 9 and 10 of the Constitution, as well as international law principles relating to family life.

9. Arguments of the Appellants

The appellants contended that section 294 unjustifiably limited their ability to expand their family and, in doing so, infringed the constitutional rights of their existing minor child. They argued that it was in the child’s best interests to have a sibling who was genetically related to him and raised within the same family unit.

They further submitted that the genetic link requirement in section 294 creates arbitrary distinctions between families who are able to contribute genetic material and those who cannot due to medical infertility. According to the appellants, this distinction undermines the values of equality and dignity and fails to accommodate the lived realities of families who rely on assisted reproductive technologies.

In addition, the appellants relied on international human rights instruments, including Article 16 of the Universal Declaration of Human Rights, which recognises the right to family life. They argued that South African law should be interpreted in a manner consistent with international law, as required by section 39 of the Constitution.

10. Arguments of the Respondents

The respondents argued that section 294 serves a legitimate governmental purpose and reflects a careful balancing of competing interests. They emphasised that the Constitutional Court had already considered and upheld the constitutionality of the provision in AB and Another v Minister of Social Development.

The respondents further submitted that the appellants had failed to demonstrate any infringement of the rights of their minor child. They argued that the inability to have a sibling through surrogacy does not amount to a violation of constitutional rights and that section 28(2) cannot be interpreted to create an entitlement to a particular family structure.

Finally, the respondents relied on the doctrine of separation of powers, asserting that it is not the role of the judiciary to substitute its own policy preferences for those of the legislature in the absence of clear constitutional invalidity.

11. Judgment and Final Decision

The court dismissed the appellants’ application. It held that section 294 of the Children’s Act is constitutionally valid and that no rights of the appellants’ minor child had been infringed. Consequently, the court declined to grant the declaratory relief sought and refused to read additional words into the provision.

12. Legal Reasoning and Ratio Decidendi

The court’s reasoning was grounded primarily in the doctrines of stare decisis and separation of powers. It emphasised that the Constitutional Court had already conclusively determined the constitutionality of section 294 in AB and Another v Minister of Social Development. As a result, lower courts are bound by that decision, regardless of whether they might personally disagree with its outcome.

In addressing the alleged infringement of the minor child’s rights, the court found that no constitutional right had been violated. The court clarified that section 28(2) does not confer a right on a child to have siblings or to dictate the manner in which a family is formed. The best interests principle must be applied contextually and cannot be used to invalidate legislation absent concrete evidence of harm.

The court further held that section 294 is rationally connected to a legitimate governmental purpose, namely the regulation of surrogacy to prevent exploitation and ensure certainty in parental relationships. Given the absence of constitutional invalidity, a reading-in remedy was neither appropriate nor justified.

13. Significance of Section 40 of the Children’s Act

In reaching its decision, the court reaffirmed the legal status of children born through artificial fertilisation. Section 40 of the Children’s Act provides that a child born as a result of artificial fertilisation must, for all purposes, be regarded as the child of the woman who gave birth and her spouse, provided consent was given. This provision applied to the appellants’ existing minor child, despite the absence of a genetic link.

The court emphasised that this legal recognition ensures stability and certainty in family relationships and underscores that genetics are not the sole determinant of parenthood in South African law.

14. Conclusion

The decision in KB and Another v Minister of Social Development and Others reaffirms the Constitutional Court’s cautious approach to surrogacy regulation and highlights the judiciary’s respect for legislative policy choices. While the appellants’ circumstances elicited sympathy, the court made it clear that constitutional adjudication cannot be driven by individual hardship alone.

The case underscores the limits of the best interests of the child principle and confirms that it cannot be invoked to override clear legislative provisions in the absence of demonstrable constitutional harm. Ultimately, the judgment reflects the balance South African courts seek to maintain between compassion, constitutional fidelity, and institutional restraint.
