UNDP has supported the Inter Parliamentary Union (IPU) in the development of a resource, “Effective Laws to End HIV and AIDS: Next Steps for Parliaments”. This knowledge product provides examples of selected parliaments that have adopted rights-based laws to support effective HIV responses, particularly in relation to people living with HIV and key populations, including sex workers, transgender people and people who use drugs. By highlighting positive examples of parliamentary processes undertaken to pass rights-based laws that support effective HIV responses, the resource aims to encourage and assist parliamentary scrutiny of legislation that impacts on HIV and provide practical guidance to parliamentarians who are interested in supporting such rights-based law reform efforts to undertake the same, pursuant to global commitments that governments have made to introduce such legislation.
