Mexico’s lower house approves constitutional amendment to annul elections over foreign interference
The proposed amendment, which defines interference to include illicit financing and digital manipulation, requires Senate approval and is unlikely to impact the federal elections scheduled for June 2027.
Mexico’s Chamber of Deputies has approved a constitutional amendment that permits the nullification of elections in instances of foreign interference. The measure passed on Thursday with 307 votes in favour, 128 against, and one abstention. It formally adds foreign interference to the existing list of grounds on which an election can be declared invalid, a move that has sparked significant debate regarding the future of Mexico’s electoral integrity.
The amendment provides a broad definition of foreign interference, encompassing illicit financing, propaganda, the systematic dissemination of disinformation, digital manipulation, and intervention by foreign governments or agencies. It also covers political, economic, diplomatic, or media pressure intended to influence public opinion. Ricardo Monreal, leader of the ruling Morena party in the lower house, defended the reform as a necessary safeguard for democracy, stating that stronger constitutional protections are required to prevent external actors from shaping domestic election outcomes.
Opposition lawmakers have strongly criticised the proposal, arguing that it creates legal uncertainty and could be exploited to contest legitimate results. Jose Elias Lixa of the National Action Party (PAN) rejected the government’s framing of the issue, stating that opposing the reform does not equate to supporting foreign interference. He drew parallels to previous debates on annulment due to organised crime, suggesting the government was using similar rhetoric to justify the new measure.
Ruben Moreira Valdez of the Institutional Revolutionary Party (PRI) also voiced opposition, distinguishing between foreign intervention and what he termed “meddling.” He warned that the amendment’s broad language could lead to unpredictable applications, such as restricting content or opinions based on international news dissemination or foreign advertising. Valdez highlighted the potential for the secondary legislation, which outlines how authorities will determine interference, to be used in ways that undermine public confidence in the electoral process.
President Claudia Sheinbaum acknowledged the potential risks, noting that foreign interference is a genuine concern and citing previous instances of foreign funding for local candidates and organisations. However, the amendment is unlikely to affect the federal elections scheduled for June 2027. Electoral reforms must be enacted at least 90 days before the start of the election process to apply, and the measure still requires approval from the Senate. Monreal has requested that secondary legislation be withdrawn due to insufficient time before legal deadlines tied to the 2027 cycle.
