The plaintiff claimed that the defendants violate the Forest Reserved Act, B.E. 2507 (1964), for trespassing, clearing forest, and illegal logging in the national forest reserved. The damages were covered in 72 rai and found the illegal logging teak and hardwood estimated 700 tons. This case was well-known as ‘Ta-Yai (grandpa-grandma) picking the mushroom’ case that the defendants first denied the charge and argued that they only entered the forest for collecting non-timber products such as mushroom. The defendants argued that they did not understand the accusation, and it was unlawful criminal procedure. However, the Supreme Court ruled that the documented evidence showed that the defendants plead guilty. Therefore, the Court dismissed the defendants’ appeal. Then, the Court reduced the punishment from fourteen years and twelve months to five years imprison.
