This article explores harmonious and discordant relations accompanying leading political participation models in public affairs. The article is focused on the analysis of whether the four most influential models of participation, namely, direct participation, indirect participation, deliberative participation, and control participation, have accompanied the multiple participation processes generated as part of the urban transformation in Medellín, Colombia between 2004 and 2015, specifically in the concise occurrence of the town hall meeting held as part of the formulation of the Land Development Plan in 2014. As explained in the paper, even if every model places a major focus on a particular aspect, they all together may converge in a collaborative and interdependent fashion. Additionally, this investigation supports that according to their immediate interests, different actors in urban transformation processes may observe these models as compatible or incompatible among each other and, accordingly, will assign each of them a dominant role depending on the specific time and interests at stake. This study may be applied as an analytical framework across contexts in Colombia, as it occurs in many Latin American cities where legal systems establish the simultaneity of these four participation models.
