As Thailand faces mounting environmental challenges, a legal battle between agribusiness giant Charoen Pokphand Foods Plc (CPF) and civil society organisation Biothai has become a test case for transparency, accountability and the boundaries of public debate.
The case revolves around claims by Biothai during a public seminar on July 26, 2024, concerning the spread of blackchin tilapia in Thailand’s waterways. Using images and various sources of information, the group linked CPF’s aquaculture operations at its Yi San Aquatic Research Center in Samut Songkhram province to the release of the invasive fish into public resources.
CPF rejected the allegations, describing them as misleading and incorrect. On that basis, the company launched legal action against Biothai’s secretary-general, Witoon Lianchamroon. The court has set its first hearing on Oct 22, 2025.
The lawsuit has drawn attention both domestically and abroad, as it pits a leading corporation against a civic society organisation.
Mr Witoon has described the lawsuit as a form of SLAPP, or strategic litigation against public participation. He argues the case is an attempt to silence or obstruct citizens who step forward to protect the environment.
He also expressed hope that international attention would ensure close scrutiny of Thailand’s judicial system, particularly whether it can safeguard the rights of the public.
CPF, however, maintains the lawsuit is not intended to intimidate or silence critics. The lawsuit is specifically in response to Biothai’s use of “false” images and information, which the company says created public misunderstanding and damaged its reputation.
At a press conference on July 30, 2024, the company outlined three alleged inaccuracies in Biothai’s presentation:
Incorrect location attribution: A pond photograph was falsely identified as CPF’s Yi San farm, said to have operated between 2010 and 2017. CPF insists the image was unrelated to its facilities and notes it terminated the project in Jan 2011, destroying all fry stock.
Distorted breeding process: Another photo allegedly showed CPF breeding blackchin tilapia eggs. The company said the image was not taken at its farms and did not reflect its standard practices.
Inaccurate farm layout: An aerial photo with layout details was presented as evidence, which CPF said was incorrect and dated back over 14 years.
Beyond the courtroom, the case draws attention to the balance between free speech and factual accuracy. While the right of the public and civil society to express concerns should be protected, there is also a responsibility to ensure that information shared is accurate.
The case highlights the broader challenge of maintaining transparency and accountability in public communication. How facts are presented, verified and contested will be closely scrutinised as the court examines the claims and evidence presented before it.
