<![CDATA[Child stunting in Indonesia is not merely a public health problem but also reflects challenges of constitutional justice and social inequality, particularly in ensuring children’s rights to health, growth, and development. This study aims to analyze how the Hexahelix Collaboration Model contributes to stunting prevention through the dimensions of social, distributive, procedural, and substantive justice. This study employed a qualitative approach using a descriptive case study design in Rancakalong District, Sumedang Regency. Primary and secondary data were collected through non-participant observation, in-depth interviews, three focus group discussions, and document analysis. Informants were selected purposively from local government institutions, village and subdistrict governments, health workers, academics, and community actors involved in stunting prevention. Data were analyzed using the interactive model of Miles, Huberman, and Saldaña through data reduction, data display, and conclusion drawing and verification. The findings show that the decline in stunting prevalence from 27.61% in 2017 to 7.59% in 2025 was accompanied by coordinated collaboration among the Hexahelix actors in promoting procedural, social, distributive, and substantive justice. The novelty of this study lies in integrating the Hexahelix Collaboration Model with multidimensional justice analysis to explain how collaborative governance can operationalize constitutional obligations in stunting prevention. This framework demonstrates that effective stunting prevention requires not only health interventions but also institutionalized collaboration, equitable resource distribution, community participation, and accountability.]]>
