The Colombian Government decided to pass under a referendum the peace accord with the former FARC. Even though the Government’s main objective was giving democratic legitimacy to such agreement, the citizens rejected it.

In addition, even today many citizens, stakeholders, and political parties use the “no argument” as a political tool to refuse further legal development of peace accords.
