Prime Minister Paetongtarn Shinawatra has moved to bolster her defence after a leaked audio of a June 15 call with Cambodian leader Hun Sen sparked a senate petition and intense scrutiny from the Constitutional Court. With a tightly framed court timetable and rising tensions along the Thai-Cambodian border, her legal team has requested five expert witnesses to testify on August 21 to clarify the context and intent of the conversation. The outcome, with a final ruling scheduled for August 29, could have immediate consequences for Thailand’s political stability.
Paetongtarn summons five experts for August 21 hearing
Paetongtarn’s legal team formally requested examination of five witnesses who they say can explain the national security context behind the leaked audio and rebut claims that her remarks breached the Code of Ethics for Political Officials B.E. 2564 (2021). The witnesses chosen include senior security and diplomatic figures directly familiar with border operations and informal negotiations, and the prime minister argues their testimony is essential to ensure a fair, fact-based review rather than decisions driven by a sensational leak. By calling these experts, her defence is aiming to show the conversation was a tactical step to de-escalate potential conflict, not an improper pledge or personal favour. The five named witnesses are: Chatchai Bangchuad, Secretary‑General of the National Security Council; Arsit Sampantharat, Permanent Secretary of the Interior Ministry; Gen. Phuchong Rattanawan, an experienced Cambodia specialist; Lt. Gen. Puttipong Chipsamut of the Military Judge Advocate General’s Department; and former ambassador Thanathip Upatising. Each, the defence says, was involved in either the operational response or diplomatic handling of the border situation and can speak to standard practices for informal back-channel talks. Their combined testimony is intended to clarify who held administrative versus security responsibilities and to demonstrate that preventive negotiation was part of an authorised effort to protect sovereignty. The Court has set a firm timetable: witnesses must appear on August 21 at 10:30 a.m., and failure to appear could trigger a no‑confidence claim. Petitioners and defendants who wish to file closing written statements must submit them by August 27, or likewise face procedural penalties. The tight schedule underscores how high the stakes are for all parties and signals the Court’s intent to proceed quickly toward the August 29 oral statements, consultation and vote.
Court sets August 29 ruling amid mounting tensions
The Constitutional Court has scheduled the decisive phase of the case for August 29, when oral statements, internal consultation and a vote are due to begin at 3:00 p.m. The timing comes amid an already fraught political environment: last year’s ouster of former Prime Minister Srettha Thavisin over a cabinet appointment and this year’s multiple probes into officials have amplified fears that judicial decisions can abruptly reshape executive leadership. Observers warn that the Court’s ruling will be watched not only for its legal reasoning but for its political reverberations at home and along the border. Tensions on the Thai‑Cambodian frontier have been rising in recent weeks, and some conservative elements are accused of trying to widen rifts between the Royal Thai Army and the Pheu Thai‑led government. The leaked phone call has been interpreted by critics as evidence of improper dealings, while the government insists the conversation was aimed at defusing a sensitive situation. The Constitutional Court’s verdict is therefore expected to influence not just the fate of one leader but the broader tone of civil‑military relations and cross‑border management. Beyond the immediate legal questions, many analysts emphasise a deeper constitutional worry: under the 2017 Constitution the judiciary and other non‑electoral bodies exert significant influence over political outcomes, creating repeated points of vulnerability. If Paetongtarn is deposed, she would join a growing list of elected leaders removed from office by judicial rulings or other non‑electoral means in recent decades — a record that critics say undermines democratic stability and leaves governance susceptible to extra‑parliamentary disruptions.
Experts to testify national security context of call
The defence says the five experts will establish that the June 15 call with Samdech Hun Sen was a negotiated effort intended to prevent escalation and protect Thai sovereignty. Testimony is expected to cover operational details, border administration, military law, and diplomatic norms, showing that phrases in the leaked clip — including one widely reported line conveyed by Isra News Agency — were part of a negotiation technique rather than an unconditional agreement. The witnesses can also explain why certain informal or back‑channel approaches are sometimes necessary in tense, fast‑moving border incidents. Chatchai Bangchuad and Arsit Sampantharat can speak to the coordination between civilian and military authorities and to routine administrative choices that aim to de‑escalate incidents, while Gen. Phuchong and Lt. Gen. Puttipong are expected to provide operational and legal context from the defence and security perspective. Former ambassador Thanathip will likely address diplomatic precedent and the practicalities of informal negotiations, where statements are often crafted to elicit further clarification rather than to bind parties to immediate concessions. The defence argues their combined account will show the interaction was consistent with protecting national interests and aligned with recommendations from security analysts on the ground. Paetongtarn’s statement to the Court stresses that her actions were carried out in the exercise of constitutional duties and not for personal enrichment or family advantage. Her lawyers contend that removing her during the proceedings would hinder coordinated government responses to the border situation and hamper the practical command relationships needed to keep tensions from escalating. By having these experts testify, the defence hopes the Court will have a fuller, fact‑based picture of intent and context before making a ruling that could have serious security and diplomatic consequences.
Decision could trigger fresh crisis in Thai politics
A ruling against Paetongtarn on August 29 could precipitate another period of acute political instability, critics caution, compounding a pattern in which leadership changes are decided outside the ballot box. If the Court finds she violated the code of ethics and removes her, Thailand would see yet another high‑profile displacement of an elected leader — an outcome that many fear would intensify polarization and invite further judicial or extra‑parliamentary interventions. Supporters argue, however, that the Court must apply the law impartially and that careful legal scrutiny is necessary in democratic governance. The government insists it will continue to perform its duties while the case proceeds, but the prospect of suspension or removal raises practical concerns about command and coordination at a time when border stability is fragile. Military and civilian officials, the defence says, need cohesive leadership to manage both immediate security challenges and sensitive diplomatic engagements with Cambodia. Opponents counter that perceived executive overreach or impropriety must be addressed to maintain the integrity of state institutions. Ultimately, the case exemplifies the broader tension between judicial oversight and political decision‑making under the 2017 Constitution: many observers argue the current framework empowers courts and non‑electoral bodies in ways that can constrain elected governments’ ability to respond flexibly to crises. Whether the August hearings and the expert testimonies will steer the Court toward a narrowly legalist ruling or a decision with sweeping political consequences remains the critical question facing Thailand as it approaches a potentially decisive moment on August 29. As the August 21 witness session approaches and the Constitutional Court prepares to deliver its judgment on August 29, Thailand faces a test of how legal process, national security and politics intersect. The defence’s request for expert testimony seeks to ensure the full context of a fraught border negotiation is considered; critics warn the proceedings could trigger another rupture in a repeatedly unsettled political landscape. Whatever the outcome, the hearings will be pivotal for the government’s ability to manage both immediate security risks and the longer‑term health of Thailand’s democratic institutions.
