Long-time member Ramiro de la Rosa Bejarano contested the presentation of Enrique Ochoa Reza as a candidate for the national leadership of the ruling Revolutionary Institutional Party (PRI).
Even while Ochoa Reza won the position, De la Rosa Bejarano said that he himself had admitted that he left the party at least twice.
The first evidence he presents is Ochoa Reza's comments before the Mexican Congress on October 21, 2010, when he was looking for the position of general councilor of the then Federal Electoral Institute.
In depositions transmitted by the Channel of the Mexican Congress, when lawmaker Juan Enrique Ibarra, from the leftist Labour Party, asked him if he was a member of the PRI, Ochoa Reza said that he was no longer a member.
According to documents presented by De la Rosa, Ochoa Reza resigned his membership in 2003.
While the new leader of the PRI presented documented evidence his long membership in the party, De la Rosa said that he does not have the required minimum 10 years in order to become the new leader.
He added that the election process then became "a mere simulation in order to legitimize the arrival of those subjected to the interests of those groups in power."
