Gustavo Petro 2010 presidential campaign

[4] In September of that same year, the Partido de la U led by its congressman Luis Guillermo Giraldo promoted a project to call a referendum to decide the possibility of electing President Álvaro Uribe Vélez for the period 2010-2014.

During this period, a series of irregularities in the process of collecting signatures were revealed, such as the confusing wording of the question that only allowed Álvaro Uribe to run for re-election in 2014, the violation of the funding limits authorized by the law or the participation of the Transval company (owned by the extradited David Murcia Guzmán) in the transfer of the signatures.

[5] However, on February 26, 2010 the Constitutional Court, with seven votes in favor and two against, declared the referendum unenforceable, by accepting the presentation of magistrate Humberto Sierra Porto according to which the project had five process and competition defects.

[citation needed] Additionally, these irregularities led to an investigation by the National Electoral Council,15 which on March 4 declared the signature collection process invalid.

[6] Due to the same facts, the Office of the Attorney General of the Nation is currently an investigation for procedural fraud against the promoters of the referendum.
