In 2012, a group of 30 villagers filed a lawsuit in Thai court against Thai government agencies, including the Electricity Generating Authority of Thailand. The plaintiffs argue a dam under construction on the Mekong River will cause significant damage to the river's ecosystem and displace millions of people. In 2022, the Thai Supreme Administrative Court dismissed the case.

Factual background

The lawsuit concerns the Xayaburi dam under construction on the Mekong River in Northern Laos, and the Power Purchase Agreement (PPA) between the Thai government agencies and the Xayaburi Power Company Limited.  The Mekong River has the world’s largest inland fishery industry. 

Under the PPA, the Electricity Generating Authority of Thailand (EGAT), agreed to purchase 95% of the electricity generated by the dam.  Without this agreement, the dam would not be economically viable.  

Legal argument

The plaintiffs argue that the PPA is illegal under Thai and international law, because the PPA was concluded without the notification, consultation, and environmental and health impact assessments required under the Thai constitution, various laws and cabinet orders.  The lawsuit also argues that the Thai government agencies were in breach of international legal obligations of best practice when they signed the PPA. 

The plaintiffs argue that the dam will cause significant damage to the river’s ecosystem and displace the millions of people living along the river who depend on it for their livelihood and food security.

Legal proceedings

In August 2012, a group of 30 villagers filed a lawsuit in Thailand’s Administrative Court against Thai government agencies, including the EGA), the National Energy Policy Council, and the Ministry of Natural Resources and Environment.

In February 2013, the Administrative Court of Thailand denied jurisdiction to hear the case because the plaintiffs could not be considered injured persons, and the court did not deem the conclusion of the PPA to be an administrative act.  The plaintiffs filed an appeal in March 2013.

In June 2014, the Thai Supreme Administrative Court accepted the case stating that “evidence suggests relevant authorities have failed to adequately listen to the opinions of people and to comply with the Procedures for Notification, Prior Consultation and Agreement…"

In October 2014, the communities filed the injunction with the Administrative Court requesting a halt on the construction of the dam while the Supreme Administrative Court rules on the legality of the PPA. 

In December 2015, the Supreme Administrative Court dismissed the case on the basis that “the defendants did not neglect their duty” and that the PPA fulfilled the required notification and consultation procedures.

The villagers appealed the decision on 26 January 2016.

In 2022, the Thai Supreme Administrative Court dismissed the case. The court ruled that “[t]he signing of the power purchase agreement with the Xayaburi Dam had no clear and direct impact on the environment and people...[and that the defendants had followed and conducted the proper procedures, the Procedures for Notification, Prior Consultation and Agreement (PNPCA).”
