After approximately a decade drafting general personal data protection laws and formulating a regime to protect personal data and privacy rights, Thailand finally issued the country’s first unified personal data protection legislation in 2019. The public was surprised when the draft Personal Data Protection Act (PDPA) was published for the final round of hearings. The draft PDPA largely adopted the preeminent personal data protection standards as expressed in the European Union’s General Data Protection Regulation (GDPR). The government expressed its objective to enhance personal data protection standards in Thailand to meet international standards, which would permit cross border transfers of personal data to Thailand, without any material limitations. The PDPA, which was finally published in the Government Gazette in May 2019, also established a new independent regulator, the Personal Data Protection Commission (PDPC), tasked with enforcing the PDPA. All members of the commission must possess the qualifications required by the PDPA. The PDPA was enacted with a grace period of one year for the requirements relating to the processing of personal data—which would provide businesses with sufficient time to adjust their practices to ensure compliance with the new requirements. It is a significant undertaking for businesses to adjust from having no general law on data protection to being required to meet high international data protection standards comparable to those in the GDPR. GPDR concepts that were incorporated into the PDPA include (1) purpose limitation, (2) transparency, (3) lawfulness and fairness, and (4) data minimization.
