Gustavo Petro, Colombia’s outgoing Marxist president, announced on Monday that he has initiated legal action to contest the election of conservative President-elect Abelardo de la Espriela.
Petro, who made history as Colombia’s first leftist president and is a former member of the Marxist guerrilla group M19, is set to leave office on August 7, transitioning power to de la Espriela, the victor in the June 21 presidential runoff.
Recently, Petro has been vocal about his allegations of “algorithmic fraud” in the election where de la Espriela won against the leftist senator Iván Cepeda, who was also a contender to succeed Petro. He further claimed that the Israeli government may have been involved in this supposed fraudulent scheme, asserting that since de la Espriela “did not win,” Cepeda should be considered “the president of Colombia.”
On July 7, the Historical Accord Coalition, which Petro leads, revealed plans to file a lawsuit to invalidate the election based on alleged incidents of fraud.
Colombians observe July 20 as Independence Day, marking the 1810 uprising against Spanish colonial rule. Petro leveraged this national holiday to rally support. He addressed supporters and claimed his “farewell” as he voiced support for left-wing governments in several Colombian cities.
During the event in Bogotá, he announced that a lawsuit had been filed against the election and indicated that he would soon provide details. Later that evening, he shared a link to a copy of the lawsuit submitted to Colombia’s highest administrative court, the Council of State, on July 17.
Petro mentioned that the lawsuit’s “technical terminology” would be clarified in an upcoming video for better public understanding.
He noted that 70,000 “digital witnesses” contributed to the case, which claims to identify “traces left by the metadata of documents” tied to election research software and alleged manipulation of citizens’ votes.
The legal complaint spans 61 pages and names the National Electoral Council (CNE), the National Civil Registry, along with President-elect de la Espriela, and Vice President-elect José Manuel Restrepo as defendants.
This lawsuit is aimed at overturning de la Espriela’s election based on allegations that electoral authorities have inadequately managed the integrity and traceability of the voting process.
The plaintiffs argue that the alleged alterations hinder the ability of citizens and judges to properly verify the connection between voting records and actual election results, which is crucial according to electoral law.
The document demands that the CNE’s declaration of de la Espriela as president-elect be revoked, alongside a thorough review of original voting documents and processes related to the presidential election.
As of now, Colombia’s State Council has not made a statement regarding the lawsuit put forward by Petro. Similarly, the defendants named in the suit, including the CNE, the National Civil Registry, President-elect de la Espriela, and Vice President-elect Restrepo, have not commented on the matter either.
Although Petro asserts that the election was “rigged,” both the United States and various other democratic nations have affirmed the legitimacy of Colombia’s 2026 presidential election. They recognize Abelardo de la Espriela as the rightful president. Additionally, international monitoring bodies, such as the Organization of American States (OAS), have validated the election outcomes, noting that no evidence of fraud was found during the observation process.
