The study included a study of documents and interviews (key informants). The authors found that 1) the Office of Election Commission of Thailand’s lack of manpower availability causes ineffective prevention and suppression. 2) Reactive working is being used for the Office of Election Commission of Thailand causes in case of no one files petition, the vote buyer is free to punish in accordance with the law. 3) Determination of punishment for vote sellers causes people to dare to provide information or testify as eyewitnesses because they are afraid of their offense and punishment in accordance with the law.
