What is the PDPA and Why Every Business Must Know It?
The Personal Data Protection Act B.E. 2562 (2019), known as the PDPA, came into full effect on June 1, 2022. Its purpose is to safeguard the rights of individuals in Thailand regarding their personal data.
With the PDPA, Thailand has aligned its data privacy standards closer to international frameworks such as the GDPR. This requires both government and private organizations to adjust and strengthen their data management practices.
Legal Status of the PDPA
The PDPA is not merely a guideline or standard; it is an Act of Parliament, making it a national law. It applies to both individuals and organizations in Thailand, as well as to actions involving the personal data of people in Thailand.
- Rights and Duties: The law grants rights to data subjects (individuals) and imposes duties on data controllers and processors (organizations or persons handling personal data).
- Regulatory Authority: The Personal Data Protection Committee (PDPC) was established to issue regulations, oversee compliance, and enforce the PDPA.
Relationship with Other Laws
While the PDPA focuses on personal data protection, it interacts with other laws:
- Electronic Transactions / Computer Crime Laws: The PDPA emphasizes protecting data and individual rights, while computer-related laws focus on punishing offenses against computer systems and stored data.
- Industry-Specific Regulations: Some sectors, such as finance or healthcare, may have stricter data protection rules. Organizations must comply with the most stringent applicable laws.
In summary, the PDPA defines the legal boundaries and requirements for handling personal data in Thailand, ensuring both protection of individual rights and accountability of organizations.
Liabilities and Legal Penalties
As a law, the PDPA sets clear penalties for violations to ensure effective enforcement. These include:
a. Civil Liability
Individuals affected by a data breach have the right to file a lawsuit for damages. Courts may award punitive damages up to two times the actual loss.
b. Criminal Liability
Applies to intentional misconduct, such as misusing sensitive data. Penalties include imprisonment of up to 1 year, a fine of up to 1 million THB, or both.
c. Administrative Penalties
For violations like lacking proper consent or security measures. Fines may reach up to 5 million THB, depending on the severity of the breach.
