The appellant, NM (a South African citizen), and the second respondent, MBM (an Australian citizen and Defence Force employee), met in Mauritius in 2019, married in South Africa in December 2020, and thereafter lived together in Australia. Their minor child, NEM, was born in Australia. In September 2022, NM travelled to South Africa with NEM to visit her parents, with return tickets for 29 October 2022. Two weeks before the scheduled return, NM informed MBM by WhatsApp that she would not be returning to Australia and intended to remain in South Africa permanently with NEM. MBM, with the assistance of the Central Authorities of Australia and South Africa (the first respondent), instituted Hague Convention return proceedings in the Gauteng Division of the High Court, Johannesburg in March 2023. NM opposed the application, raising a defence under Article 13(b) of the Hague Convention (grave risk of physical or psychological harm or intolerable situation) and relying on a social worker’s report. At the eleventh hour before the hearing in November 2023, NM filed a counterapplication seeking a declaration that section 275 of the Children’s Act 38 of 2005 was unconstitutional to the extent that it incorporated the Hague Convention. The High Court separated the constitutional challenge under Uniform Rule 33(4), found that the Article 12 jurisdictional requirements were satisfied and that NM had failed to discharge the onus under Article 13(b), and ordered NEM’s return to Australia. NM unsuccessfully sought leave to appeal the High Court and subsequently appealed to the Supreme Court of Appeal. During the appeal hearing in December 2024, NM indicated that she had changed her position and was willing to accompany NEM to Australia. MBM confirmed various undertakings designed to ameliorate the consequences of the return order.
