On 26 June 1987 the Convention against Torture came into force. It was an important step in the process of globalizing human rights and acknowledging that torture, and all forms of inhuman or degrading treatment or punishment, are absolutely and universally illegal.
Since then many human rights groups have been observing the day as International Day against Torture.
In 1997, the United Nations General Assembly decided to mark this historic date and designated 26 June each year as International Day in Support of Victims of Torture.
On 9 August 1999 several human rights organizations jointly submitted to the UN High Commissioner for Human Rights a manual on the effective investigation and documentation of torture and other cruel, inhuman or degrading treatment or punishment.
The document, known as Istanbul Protocol provides a set of guidelines for the assessment of persons who allege torture and ill treatment.
