The Protocol to Prevent, Suppress, and Punish Trafficking in Persons to the UN Convention against Transnational Organized Crime was adopted in 2000 and entered into force on December 25, 2003.
The UNODC states, "The Protocol to Prevent, Suppress and Punish Trafficking in Persons, especially Women and Children, was adopted by General Assembly resolution 55/25. ... It is the first global legally binding instrument with an agreed definition on trafficking in persons. The intention behind this definition is to facilitate convergence in national approaches with regard to the establishment of domestic criminal offences that would support efficient international cooperation in investigating and prosecuting trafficking in persons cases. An additional objective of the Protocol is to protect and assist the victims of trafficking in persons with full respect for their human rights."
