[1][2] Guillermo Reyes graduated as a lawyer from the Faculty of Jurisprudence of the Universidad del Rosario de Colombia in 1989 and specialized in Tax Law at the same university, while he was part of the creation of the Séptima balloteta movement, which led him to be an advisor in the Constituent Assembly of Colombia in 1991.

[4] In October 2015, Semana alleged that Guillermo Reyes had plagiarised in his Complutense University of Madrid PhD thesis.

In the text "El nuevo orden político y electoral en Colombia" by Reyes, published in 2004 by Konrad Adenauer Foundation.

[9] According to Andrés Bermúdez, Reyes again copied several of the same pieces of text in "Régimen electoral y de partidos políticos.

[9] Reyes responded to the new allegations by stating to La Silla Vacía that it was not a case of plagiarism, and that in the 2004 publication, there had been omissions which were later corrected.
