EU Court Adviser Backs Right to Erase Baptismal Records Under GDPR

The European Union's sweeping data privacy laws extend to the centuries-old practice of recording baptisms, a top court adviser declared on October 1, 2026. The opinion challenges the Catholic Church's autonomy over its internal sacramental registers, setting up a major legal test for religious freedom.[1][2]

The dispute originated in Belgium, where a man baptized as an infant in 1955 formally requested that the Diocese of Ghent erase his records after he left the faith. Instead of deleting the entry, the diocese drew a diagonal line through his name and added a marginal note stating his departure.[1][3]

The Belgian Data Protection Authority ruled in December 2023 that the diocese must fully erase the data to comply with the law. Following an appeal by the Church, the Brussels Court of Appeal referred the matter to the Court of Justice of the European Union to determine how the General Data Protection Regulation applies to religious archives.[1][3]

Advocate General Laila Medina concluded that a baptismal register constitutes a structured filing system under the GDPR. Therefore, an adult wishing to sever ties with the Church has the right to demand the removal of their childhood data, regardless of the institution's internal rules.[2][3]

Defining erasure under European law

Medina explicitly rejected the Church's argument that a marginal annotation satisfies the law. She noted that striking a name through while leaving it legible is merely a rectification, whereas the GDPR's Article 17 guarantees the right to be forgotten through actual deletion or obliteration.[1][3]

"The right to erasure under the GDPR may, in principle, apply to personal data contained in baptismal registers," Medina wrote in her official opinion. She added that continued storage could cause emotional distress for those seeking closure from a religious community.[2]

The legal mechanism hinges on the right to object under Article 21 of the GDPR. Once a former member formally objects to the processing of their data, a general legitimate interest is no longer sufficient to justify keeping the record intact.[3]

The Diocese of Ghent argued that baptism is a historical event that cannot be undone, and that the physical register is an inviolable historical artifact. They maintained that the Church holds a legitimate interest in preventing identity fraud, as Catholic doctrine dictates a sacrament can only be received once.[1][3]

The Church's defense of sacramental records

Medina found the historical artifact argument unconvincing, pointing out that dioceses routinely update these registers with subsequent sacraments or marginal notes. If the books can be modified to reflect a person leaving the faith, she reasoned, they can also be modified to render a name illegible.[3]

Following the opinion, the Commission of the Bishops' Conferences of the European Union issued a stark warning on October 5, 2026. The organization argued that forcing the deletion of entries would create significant legal uncertainty across member states and disrupt centuries of administrative tradition.[4][5]

The bishops emphasized that physical erasure would compromise the data of parents, godparents, and ministers listed on the same pages. Because many historical registers are physical books with double-sided pages, obliterating one entry could inadvertently destroy the sacramental records of entirely unrelated individuals.[4][5]

They also warned that destroying these records would severely hinder the Church's ability to verify information required for marriage cases. Without a definitive registry, dioceses would struggle to confirm whether an individual had already been baptized or married elsewhere.[4][5]

Balancing religious freedom and privacy

Under Medina's interpretation, the burden of proof shifts entirely to the religious institution. To deny an erasure request, a diocese must demonstrate compelling legitimate grounds that outweigh the individual's fundamental privacy rights, a threshold the Advocate General suggested is difficult to meet.[1][3]

The Advocate General's opinion is not legally binding, but the Luxembourg court follows such guidance in the vast majority of its final judgments. A definitive ruling is expected in the coming months, which will apply uniformly across all 27 EU member states.[1]

If the court adopts the recommendation, dioceses across Europe will need to overhaul their record-keeping practices. The decision will ultimately test the boundaries between the institutional autonomy of religious organizations and the digital self-determination of European citizens.[1][4]
