This first study published by the WHO Civil Society Commission evaluates the involvement of civil society in drafting some key resolutions and decisions adopted by the 77th World Health Assembly (WHA77) in May 2024. The study covers civil society consultations during the drafting of a) WHA Resolution on Social Participation, (b) WHO Fourteenth General Programme of Work, and (c) WHA Resolution on Climate Change and Health. The resolutions were initiated by Member States, WHO, and the Member States, respectively. Therefore, each of the case studies presents a different trajectory of process followed. For each of these three cases, the study provides detailed background information as well as assessments by key actors: What is the “real” story behind the interaction between WHO Secretariat or Member States and civil society organizations, what have been key challenges on the way, and how can the story told inspire others to do the same. Each case concludes with assessments of lessons learnt and recommendations to all actors involved. The experiences and lessons from the three case studies provide a solid foundation for advancing meaningful and comprehensive civil society engagement in global health decision-making. By embracing these lessons, the WHA and WHO as well as civil society can strengthen their commitment to participatory governance, making health policies more responsive, equitable, and effective.
