The Thai public prosecutor (อัยการ) is an independent state officer who conducts criminal prosecutions on behalf of the Kingdom, under the Public Prosecutor Organ and Public Prosecutors Act B.E. 2553 (2010). Prosecutors decide whether to indict after police investigation, direct further investigation, appear in court, and file appeals. In some civil matters they also represent the public interest, for example in guardianship or incapacity proceedings.
