Glossary
Plain-language definitions of the legal and statistical terms used across this site — sourced to Thai statute and the same public datasets the rest of the site draws on.
Section 78 (Thai Criminal Code)
The plea-mitigation statute that lets a Thai court reduce a sentence by up to one-half when the defendant has been "useful" — in practice, when they confess.
Section 79 (Thai Criminal Code)
The companion mitigation provision that enumerates non-confession grounds a court may use to reduce sentence (youth, intoxication, provocation, etc.).
Section 112 (Lèse-majesté)
The criminal offence of defaming, insulting, or threatening the Thai King, Queen, Heir-Apparent, or Regent — three to fifteen years per offence, stacked per message.
Lèse-majesté
The legal doctrine criminalising insult to the sovereign. In Thailand it is encoded in Criminal Code §112 and carries felony-grade sentences.
Pretrial remand (detention)
Imprisonment of an accused person before trial or before conviction — used in Thailand at one of the higher rates in the region.
Bail
Conditional release of an accused person pending trial — denied or set unaffordably high for serious Thai charges, particularly drugs, lèse-majesté, and trafficking.
Plea reduction
The Thai practice of cutting a sentence by up to one-half when the defendant confesses — formalised by §78, used in nearly every drug and §112 case that ends in conviction.
Statutory maximum
The ceiling sentence permitted by the statute creating the offence — the number that defines the "Max" half of "Plead or Max".
WJP Rule of Law Index
The annual World Justice Project country index. Thailand placed 78th of 142 in 2024 with an overall score of 0.50/1.00.
Court of First Instance
The trial-level court where Thai criminal cases begin — provincial Courts, the Criminal Court (Bangkok), the Central Juvenile and Family Court, and specialised divisions.
Judicial diversion
Routes that resolve a case without a full criminal trial — drug-treatment programs, mediation, deferred prosecution. Thailand's diversion infrastructure is narrow.
Computer-Related Crime Act
The Thai cybercrime statute (B.E. 2550, amended 2017) whose §14 criminalises online speech that duplicates and amplifies criminal defamation under §326–328.
Section 14, Computer-Related Crime Act
The §14 speech provisions of the Thai cybercrime statute. Five-year statutory maximum per offence for entering "false" or "distorting" data; often stacked with Criminal Code §326–328 for a single act of speech.
Section 116 (Thai Criminal Code) — Sedition
The Thai sedition statute. Seven-year maximum for speech that "causes people to violate the laws" or "raises unrest". Routinely used against peaceful protest.
Sections 326–328 (Thai Criminal Code) — Criminal defamation
Thai criminal defamation. §326 covers the basic offence (up to one year); §328 covers publication (up to two years). Truth is not always a defence.
Section 145, Narcotics Code B.E. 2564
The 2021 Thai Narcotics Code section for Category-1 narcotics (heroin, methamphetamine, cocaine). Possession carries up to 15 years; trafficking scales to life or death.
Court of Appeal (Thailand)
The regional appellate courts that review Court of First Instance verdicts. Notable feature: they can INCREASE a sentence on appeal.
Dika Court (Thai Supreme Court)
The apex court in the Thai judicial hierarchy. Reviews Court of Appeal decisions on questions of law or, exceptionally, of fact.
Royal pardon (Thailand)
The periodic mass-pardon mechanic — issued on coronation anniversaries, birthdays, and other royal occasions — that briefly reduces the prison population by tens of thousands.
Article 36, Vienna Convention on Consular Relations
The treaty article requiring host states to inform detained foreign nationals, "without delay", of their right to have their consulate notified.
Prisoner Transfer Treaty
A bilateral treaty allowing convicted foreigners to serve the remainder of a Thai sentence in their home state. Thailand has active treaties with the US (1982), UK (1990), Australia (2002), and Canada (2002).
US TIP Report Tier 2 Watch List
The US State Department's trafficking-tier classification for countries whose "efforts are not proportional to the significant increase in trafficking". Downgrade from Tier 2 to Tier 3 triggers automatic aid restrictions.
Custodial vs non-custodial sentence
Custodial = imprisonment (any facility). Non-custodial = fine, probation, suspended sentence, or community service. In Thailand, most drug and §112 convictions are custodial.
Presumption of innocence (Thailand)
A Thai constitutional principle. Its practical force is undercut by routine bail denial for serious charges and the 22.5% pretrial share of the inmate population.
Right to counsel (Thailand)
A Thai Criminal Procedure Code guarantee. In practice, state-provided defence is limited; most foreign defendants and many Thai defendants retain private counsel or plead unrepresented at first appearance.
