Nattapong Rueangpanyawut, leader of the People’s Party, has denied all allegations in a defamation case brought by Gulf Energy Development. He appeared in court on 16 February to submit his formal statement and supporting evidence in response to charges of defamation by advertisement and causing reputational damage to the company.

Speaking after the hearing, Mr Nattapong said the proceedings were in line with legal process. He confirmed that he had previously applied for bail and that he had now formally submitted his defence and evidence to the court. He stated that he rejects all accusations and maintains his innocence.

The case concerns allegations that statements made by Mr Nattapong damaged the reputation of Gulf Energy Development. He declined to disclose the names of defence witnesses, citing the need to protect their privacy. He said the witnesses would testify on behalf of those accused in relation to efforts to push for energy policies in Thailand that do not result in energy monopolies.

In the same case, Supachote Chaisajja, a People’s Party party-list MP candidate, also submitted his statement and evidence later in the afternoon of 16 February. Another party-list MP candidate, Worapop Viriyaroj, has a court appointment set for May. The proceedings form part of a broader legal process involving members of the People’s Party and the company.

Mr Nattapong reiterated that he stands by his actions and intends to defend himself through the judicial process. He did not provide further details about the substance of the allegations or the evidence submitted. The court’s decision to begin examining witnesses in October marks the next significant stage in the case.

Daily News reported that the outcome of the hearings could have implications for the individuals involved and for ongoing debates concerning Thailand’s energy sector. For now, the case remains before the court, with all parties preparing their evidence. Further developments are expected as the October hearings approach.

The number of law suits against PP is becoming ludicrous. Everything they do seems to be a legal issue.

Seen plenty of these cases over the decades. Thailand’s defamation laws are very strict, and the whole issue of “face” plays such a big part.

When politicians or big business are involved, it usually ends up in high‑profile court battles.

Nattapong has denied the allegations and put in his defence, so now it’s in the court’s hands.

What strikes me is the timing, with hearings not until October. That leaves everyone waiting around for months, with reputations hanging in limbo. Typical of how the system grinds along here.

Beyond the individuals, the eventual outcome could also affect policy and big monopolies.

Just another reminder of how slowly the wheels of justice turn in Thailand

Got to drop these defamation laws including 112. They're nothing but harmful to free discourse in Thai society and don't protect anyone.
