PDPA explainer

PDPA Purpose Limitation in Thailand

Purpose limitation under Thailand's PDPA explained, with a documented case example about data used beyond its original task.


General principle

Under Thailand's PDPA, a controller must specify the purposes of processing and must not process data for purposes beyond those notified unless another lawful ground applies.

Purpose limitation asks a practical question: what task was this data made available for, and is the current use the same task?

How this issue appears in this case

In this case, the complainant asked whether data connected with Product B was used for a task defined by Product A. That question is not resolved in the public record.

This section is not a legal conclusion and does not state that any party is at fault.
