Officially, the constitution of Sri Lanka guarantees human rights as ratified by the United Nations. However, human rights has come under criticism by Amnesty International, Freedom from Torture, Human Rights Watch, and the United States Department of State. British colonial rulers, the LTTE, and the government of Sri Lanka have been accused of violating human rights. A report by an advisory panel to the UN secretary-general accused both the LTTE and the Sri Lankan government of war crimes during final stages of the civil war. Corruption remains a problem in Sri Lanka, and there is little protection for those who stand up against corruption. The 135-year-old Article 365 of the Sri Lankan Penal Code criminalises gay sex and provides for a penalty of up to ten years in prison.
