A significant new procedural law for fines in Thailand results in the mass removal of certain types of fines for criminal penalties and alters procedures for certain administrative monetary penalties. There are generally two types of fines imposed under Thai law: criminal fines and administrative fines. However, there will soon be a type of fine that exists outside of the criminal or administrative legal mechanisms: the phinai fine, which is neither a criminal penalty nor an administrative fine. Instead, a phinai fine—which must be paid to the state—is one assessed in lieu of criminal penalties for less-serious offenses. Perhaps the closest equivalent to a phinai fine would be a “civil” fine, but there is no official translation of Thailand’s first law dedicated to these fines, the Act on Phinai Fine Proceedings B.E. 2565 (2022) (ACFP), which was published in the Government Gazette on October 25, 2022. Before proceeding further to discuss the significance of the new law, a note should be made regarding the term phinai. As there has been no official translation of the ACFP, there is currently no official translation of phinai. Under the ACFP, “to seek a phinai fine” (or prap pen phinai) was determined to have the specific meaning of ordering a phinai penalty offender to pay a phinai fine. The meaning of the term as defined reflects a type of phinai penalty, which is neither a criminal penalty nor an administrative fine. In the future, there is a possibility that the official translation of the ACFP may use a different term. The passage of the ACFP provides Thailand with a special procedural law for all phinai fines, ultimately resulting in a significant change in the categorization and collection of fines and administrative monetary penalties.
