The appellant, Pathmanathan (husband), and the respondent, Indira Gandhi (wife), were married and had three children. In March 2009, the husband converted to Islam. In April 2009, the husband obtained certificates of conversion to Islam issued by the Pengarah Jabatan Agama Islam Perak over all three children as well as an ex-parte interim custody order over the children. In September 2009, he obtained a permanent custody order from the Syariah Court. In 2013 and 2014, the mother obtained orders from the High Court annulling the unilateral conversions and the Syariah Court’s custody order, inter alia, on the grounds that vesting equal rights to both parents to decide on a minor child’s religious upbringing and religion would be in accordance with international human rights principles, specifically the convention on the Rights of the Child (CRC) and CEDAW. The first appeal in this case concerned the validity of the conversion of the children to Islam. The majority in the Court of Appeal allowed the husband’s appeal and held that the Syariah Court had exclusive jurisdiction to determine the validity of the children’s conversion to Islam. Dealing with the issue of whether the conversions violate international norms, the Court noted that international treaties do not form part of domestic law unless those provisions have been incorporated into domestic law and that the High Court’s approach of following very closely the standard of international norms in interpreting the Federal Constitution is not in tandem with the accepted principles of constitutional interpretation. Accordingly, the Court of Appeal did not declare that the conversions of the children were invalid. The Federal Court overturned the lower courts’ decisions on appeal, reasoning that the children had not met the statutory requirements of conversion. Specifically, the Court found that the children did not state the two clauses of the Affirmation of Faith in Arabic as the Perak Enactment requires for a valid conversion to Islam. In addition, the Federal Court held that mothers have parental rights equal to fathers, so the permission of both parents is required for a child’s religious conversion.
