- LGBT discrimination becomes no protections.
- Homosexual activity becomes legal.Private, adult, consensual, and non-commercial sodomy was decriminalized in Thailand in 1956. However, same-sex attraction and transgender identities were still seen as socially unacceptable in many cases: those whose gender expression or behavior falls out of social norms are less likely to be tolerated or accepted. Through the Penal Code Amendment Act of 1997 (Thai: พระราชบัญญัติแก้ไขเพิ่มเติมประมวลกฎหมายอาญา-(ฉบับที่-14)-พ.ศ.-2540), the age of consent was set at fifteen years regardless of gender or sexual orientation. In 2002, the Ministry of Health announced that homosexuality would no longer be regarded as a mental illness or disorder. In 2007, the Thai Government expanded the definition of a sexual assault and rape victim to include both women and men. The government also prohibited marital rape, with the law stipulating that women or men can be victims.
