Guatemalan president Bernardo Arévalo on May 5, 2026 named career judge Gabriel Estuardo García Luna as new prosecutor general (Fiscal General) and head of the Ministerio Público for the 2026-2030 term, ending the sanctioned 8-year tenure of Consuelo Porras Argueta who is set to step down on May 16.
García Luna, 49, scored 72.21 points in the Comisión de Postulación evaluation issued April 24 and was selected from a final shortlist of 6 candidates after Arévalo conducted personal interviews at the Palacio Nacional.
He inherits a Ministerio Público where over 90% of criminal cases receive no effective response and faces immediate pressure from the OAS, US, and EU to restore institutional autonomy.
Key Points
— Arévalo announced García Luna as new fiscal general on May 5; takes office May 17.
— 4-year term (2026-2030); replaces Consuelo Porras Argueta after 8 years (2018-2026).
— Selected from 6 finalists; scored 72.21 points in Comisión de Postulación evaluation.
— Porras sanctioned by US and EU for corruption and undermining democracy.
— Movimiento Pro Justicia: more than 90% of criminal cases receive no effective response.
Who Is García Luna
The Rio Times, the Latin American financial news outlet, reports that Gabriel Estuardo García Luna brings 29 years in the Organismo Judicial as career judge, magistrate, and legal scholar, with a doctorate in Law from Universidad de San Carlos and a master’s in Criminal Law from Universidad Rafael Landívar. He has served as judge of the Tribunal Segundo de Sentencia Penal in Mixco, presiding magistrate of the Junta de Disciplina Judicial, and magistrate at the Sala Regional Mixta de la Corte de Apelaciones in Cobán. He currently serves as criminal-law adviser to the Despacho Superior of the Procuraduría General de la Nación and has been a faculty member at Rafael Landívar.
In his statement Arévalo emphasized institutional independence: “The Ministerio Público receives a new authority who does not arrive to serve a president, the government of the day, or particular or spurious political interests, but to serve an independent, objective justice put at the service of the Republic and the peoples that make up the Guatemalan nation”. García Luna told the Comisión de Postulación that the MP must operate “without external interference” and oriented to the search for “material truth”, while he committed to implementing merit-based mechanisms within the MP and creating multidisciplinary teams for complex investigations.
The Porras Inheritance
Consuelo Porras Argueta led the Ministerio Público for 8 years across 2 consecutive terms, with her tenure marked by US Treasury and EU sanctions for corruption and obstruction of democracy, particularly over her attempts to annul the 2023 election results that brought Arévalo to power. Porras did not make the final shortlist this time, after Arévalo had publicly described her continuation as a “dangerous” risk to the country, while a UN expert group requested investigation in February of her alleged role in irregular international adoptions of 80 indigenous children at the Hogar Temporal Elisa Martínez between 1982. Porras has rejected all such allegations as baseless.
International and Business Reaction
The OAS issued a May 6 statement urging an “orderly and peaceful” transition and calling on García Luna to commit unequivocally to MP autonomy, while warning against any institutional resistance that could prolong the crisis. AmCham Guatemala welcomed the appointment as critical for legal certainty and the investment climate, while the CACIF (Comité Coordinador de Asociaciones Agrícolas, Comerciales, Industriales y Financieras) formally congratulated García Luna and expressed confidence in institutional strengthening. Exiled former prosecutor Juan Francisco Sandoval cautioned in X that the change of authority alone is insufficient and demanded a “deep reform that guarantees independence, prosecutorial career path, real controls, and an end to the political use of justice”.
García Luna becomes the 13th lawyer to lead the Guatemalan investigative body, taking office at a time when international pressure from the US and EU is focused on reversing the criminalization of journalists, persecution of indigenous leaders, and harassment of justice operators. The new prosecutor’s immediate challenge is to break the “dismissal-rate” approach implemented under Porras, which prioritized statistical case closures over substantive resolutions, while the broader stakes include restoring credibility to a justice system whose collapse Movimiento Pro Justicia describes as systemic. Markets and the business community will watch the first 100 days for signals on legal certainty and case prioritization.

Frequently Asked Questions
Who is Gabriel García Luna?
Gabriel Estuardo García Luna is a 49-year-old Guatemalan career judge with 29 years in the Organismo Judicial. He holds a doctorate in Law from Universidad de San Carlos, a master’s in Criminal Law from Universidad Rafael Landívar, and currently serves as criminal-law adviser to the Procuraduría General de la Nación. He scored 72.21 points in the Comisión de Postulación evaluation and was selected from a 6-candidate shortlist after personal interviews with President Arévalo at the Palacio Nacional.
Why is the Porras tenure ending?
Consuelo Porras Argueta led the Ministerio Público for 8 years across 2 consecutive terms (2018-2026), with sanctions imposed by the US Treasury and the EU for corruption and obstruction of democracy. Her tenure was marked by attempts to annul the 2023 election results that brought Arévalo to power and by criminal pursuit of journalists, judges, prosecutors, and human-rights defenders. She did not make the final 6-candidate shortlist for renewal and steps down on May 16.
What is the OAS position?
The OAS issued a May 6 statement urging an “orderly and peaceful” transition between Porras and García Luna, calling on the new fiscal general to commit unequivocally to MP autonomy and warning against institutional dilatory maneuvers. The OAS framing reflects broader international pressure from the US and EU on Guatemala to reverse criminalization of journalists, persecution of indigenous leaders, and harassment of justice operators that marked the previous administration. AmCham Guatemala and CACIF welcomed the appointment for legal certainty and investment climate.
What is the immediate challenge?
Movimiento Pro Justicia documents that more than 90% of criminal cases receive no effective response under the current MP framework, reflecting a systemic operational collapse. García Luna must break the Porras-era “dismissal-rate” approach (priorizing statistical case closures over substantive resolution), restore the prosecutorial career path, and create multidisciplinary teams for complex investigations. Exiled former prosecutor Juan Francisco Sandoval has warned that mere personnel change is insufficient without “deep reform” of the institutional framework.
