Firm annotation
Section 181 is a bridging provision in Title 2 (Trial) that carries sections 139 and 166 into the trial stage by mutatis mutandis application. Section 166, in particular, governs the effect of a prosecutor's failure to appear on the appointed date and allows the court to dismiss the charge. In practice, the Supreme Court has held that this consequence attaches only to genuine trial or evidence-taking dates, so a prosecutor's absence from, for example, a mediation appointment that is not a hearing does not justify dismissal. The reach of the section is thus tied precisely to what kind of appointment the prosecutor missed.
Why this matters in practice
For a private prosecutor, this is a trap to avoid: through Sections 181 and 166, failing to appear on a genuine hearing or evidence date can get your case dismissed. The saving point, confirmed by the Supreme Court, is that the dismissal rule bites only on real hearing dates, not on ancillary appointments like a mediation meeting. If you bring a private criminal prosecution, calendar every hearing carefully and arrange representation; discuss the risks first in an online consultation with a Thai lawyer.
Supreme Court decisions interpreting this section
-
Supreme Court Judgment No. 3522/2563 (2020)
A prosecutor's absence from a preliminary or mediation appointment that is not an evidence-examination or hearing date does not meet the requirement of Section 166 paragraph one together with Section 181, so the court cannot dismiss the charge for it.
The trial court dismissed the charge because the prosecutor missed a date set for reconciliation. The Supreme Court held that because this was not an evidence-examination or hearing date, it did not fall under Section 166 paragraph one with Section 181, so the dismissal was unlawful and was rightly set aside by the appellate court.

Supreme Court Judgment No. 9280/2551 (2008)
Where the private prosecutor fails to appear on a scheduled date to continue examining his own testimony, the court may dismiss the charge under Section 166 paragraph one together with Section 181.
After the private prosecutor had begun testifying over two hearing dates, he failed to appear at the next scheduled examination date. The trial court dismissed the charge under Section 166 paragraph one together with Section 181, the consequence of a prosecutor's non-appearance carried into the trial stage.

The charge can be dismissed. Section 181 applies Section 166 to the trial, so a prosecutor's absence on a genuine hearing or evidence date allows the court to dismiss the case.
Does missing a mediation date allow dismissal under Section 181?
No. The Supreme Court has held the dismissal rule under Sections 166 and 181 applies only to genuine hearing or evidence dates, not to a mediation appointment that is not a hearing.
