In May 2019, Thammakaset filed a criminal complaint with the Lopburi Kwaeng Court agaisnt Ms. Ka Thway Soe, Mr. Nan Toe, Mr. Nan Win, three former Thammakaset workers, and Ms. Suthasinee Kaewleklai, labour rights defender and coordinator of Migrant Worker Rights Network (MWRN) for allegedly providing false information to an official. The suit arises from submitting information over alleged labour rights violations committed by Thammakaset to the Department of Labour Protection and Welfare in 2016. The preliminary hearing was held on 27 January 2020. On 18 March 2020, the Loburi Kwaeng Court dismissed the complaint because the Don Mueang Kwaeng Court had already ruled on this matter and found that the defendants did not provide false information to the Labour Inspector.
