Section 30: Court's power to maintain order

Statutory text (Thai original)

ให้ศาลมีอำนาจออกข้อกำหนดใด ๆ แก่คู่ความฝ่ายใดฝ่ายหนึ่งหรือแก่บุคคลภายนอกที่อยู่ต่อหน้าศาลตามที่เห็นจำเป็น เพื่อรักษาความเรียบร้อยในบริเวณศาล และเพื่อให้กระบวนพิจารณาดำเนินไปตามเที่ยงธรรมและรวดเร็ว อำนาจเช่นว่านี้ ให้รวมถึงการสั่งห้ามคู่ความมิให้ดำเนินกระบวนพิจารณาในทางก่อความรำคาญ หรือในทางประวิงให้ชักช้าหรือในทางฟุ่มเฟือยเกินสมควร

English translation

The court has the power to issue any directions to any party or to a third person present before the court, as it deems necessary, in order to maintain order within the court precincts and to ensure that the proceedings are conducted fairly and expeditiously. Such power includes ordering a party not to conduct the proceedings in a manner that causes annoyance, or in a manner that is dilatory and causes delay, or in a manner that is unnecessarily extravagant.

Firm annotation

Section 30 confers the court's general power to keep order in the courtroom and manage the conduct of proceedings, directed at parties and at third persons present before the court. It expressly reaches conduct that is annoying, dilatory, or unnecessarily extravagant. This provision is the predicate for contempt of court under Section 31(1): disobeying a direction issued under Section 30, or behaving improperly in the court precincts, may constitute contempt, which is then punished under Section 33. The power is significant but bounded; an order is only proper where it genuinely serves order or the fair and speedy conduct of the case.

Why this matters in practice

For litigants and their lawyers, Section 30 sets the boundaries of acceptable conduct in court. Disobeying a proper direction, or acting disruptively in the court precincts, risks contempt of court under Section 31(1) and punishment under Section 33. At the same time, the court's power is not unlimited: an order barring a party from proceeding is improper where the conduct was not actually annoying or dilatory. If you believe a control order against you was wrongly made, it may be challengeable. Understand the ground rules before you go to court in Thailand.

Supreme Court decisions interpreting this section

  1. Supreme Court Judgment No. 1715/2548 (2005)

    Section 30 empowers the court to issue directions to maintain order and to prohibit conduct that causes annoyance or delay; improper behaviour in the court precincts can constitute contempt under Section 31(1) in its own right, without a prior Section 30 order being required.

    The accused threatened a witness in the court precincts before the witness testified, which the Court held to be disorderly behaviour amounting to contempt of court. The Court rejected the argument that contempt under Section 31(1) always requires a prior direction under Section 30, explaining that Section 30 concerns directions the court issues to maintain order, while disorderly behaviour in the precincts is punishable in itself.

  2. Supreme Court Judgment No. 5346/2547 (2004)

    The plaintiff complained that the Labour Court's direction forbidding him from filing further documents of the same kind did not comply with Sections 30 to 33, but the Supreme Court did not decide that question. It held instead that a motion to set aside proceedings said to be irregular at the Supreme Court stage is for the Supreme Court itself to decide, so a court below that dismisses such a motion without sending it up acts improperly, and, no statute making an order on such a motion final, refusing an appeal against that order is improper too. On the motion itself, a Supreme Court judgment is final from the moment it is read to the parties and cannot be added to or amended, save for a minor error or slip; where the judgment dealt with every ground raised, there is no slip to correct.

    After the Supreme Court affirmed the dismissal of his labour claim, the plaintiff moved in the Labour Court to set aside the Supreme Court own proceedings as irregular. The Labour Court dismissed the motion because the case was final, refused his appeal against that order, and made a direction forbidding him from filing further documents of that kind. The Supreme Court held that a motion alleging irregularity at the Dika stage is for the Supreme Court to decide, so the Labour Court should have sent it up instead of dismissing it; that no statute makes an order on such a motion final, so refusing the appeal was also wrong; and it quashed both orders. Deciding the motion itself, it held that a Supreme Court judgment is final from the moment it is read and cannot be added to or amended except for a minor slip. The earlier judgment had held that all the plaintiff grounds disputed the Labour Court assessment of the evidence and were therefore appeals on fact barred by section 54 paragraph one of the Act establishing Labour Courts; it had dealt with every ground, so there was no slip to correct and the motion was dismissed.

  3. Supreme Court Judgment No. 8912/2551 (2008)

    The court may issue a direction under section 30 only in one of two situations: where it is necessary to maintain order in the court precincts so that the proceedings are fair and expeditious, or to forbid a party from conducting the proceedings in a manner that is annoying, dilatory or unnecessarily extravagant. A direction issued under section 36(2) is not a direction under section 30, so breaching it cannot be contempt under section 31(1) read with section 30.

    On the facts there was no necessity to maintain order in the court precincts and no conduct of the proceedings that was annoying, dilatory or unnecessarily extravagant, so neither situation in section 30 arose. The direction the trial court had issued was made under section 36(2) and was not a direction under section 30. Whether or not the first accused had given the copied tapes to the second accused to disclose, his conduct therefore could not be contempt under section 31(1) read with section 30, and the Supreme Court, raising the point as one of public order, acquitted him of that charge. Whether breaching the section 36(2) direction amounted to disorderly conduct in the court precincts was not decided below and so was not before the Court.
