Porto Alegre's Workers' Party administration under mayor Olívio Dutra launched the Orçamento Participativo in 1989, letting neighborhood assemblies elect delegates who allocated part of the city's investment budget. Hundreds of cities copied it. At home it was hollowed out: assemblies stopped taking new demands after 2016, and the 2022 revival runs on a reserve the city sets itself — R$25 million for 2026.
📊 Impact
Project completion averaged 97% under Workers' Party administrations (1992-1999) but only 43% under the Fogaça administration (2005-2010) (Melgar 2014). Participatory budgeting deliberated 100% of public investment resources in 1993-1996; by 2023 it covered 0.14% of municipal expenditure (Gugliano 2026). The city reports 18,055 participants across 23 assemblies in 2025, its second-highest turnout since 1989.
🎓 Lesson
The world's most-copied democratic innovation was never protected by law. When the party that built it lost power, successors kept the name, cut the money and stopped the assemblies — and the city that exported the model spent two decades dismantling it at home.
