The attorney general's office then said it was insisting on charging Glas with respect to the case involving public funds collected to aid the reconstruction of Manabí Province after a 2016 earthquake.

[12] Instead, on 3 April, Mexican president Andrés Manuel López Obrador alluded in a press conference to the fact that Luisa González, the presidential candidate of the pro-Correa Citizen Revolution Movement, had an advantage in polling for the 2023 Ecuadorian general election, but that after the murder of Fernando Villavicencio her polling numbers had dropped,[13] implying the assassination had affected the election results.

[14] After the president's comments, on 4 April, Mexican ambassador Raquel Serur Smeke was declared a persona non grata and the Ecuadorian Foreign Ministry invoked the principle of "non-intervention" in the internal affairs of another country and Article 9 of the Vienna Convention on Diplomatic Relations to request her departure.

[16] On 5 April, the Mexican secretary of foreign affairs, Alicia Bárcena, called for the government of Ecuador to arrange safe passage as soon as possible so that Glas could leave for Mexico.

[24] Foreign minister Gabriela Sommerfeld defended the raid, saying that the decision was made by Noboa after the government had determined an "imminent flight risk" on the part of Glas and after it had exhausted all possibilities for diplomatic dialogue with Mexico.

[27] On 12 April, a three-person tribunal ruled that his arrest was "illegal and arbitrary" due to lack of "authorisation from the head of the Foreign Ministry and political affairs" at the embassy, but upheld his imprisonment, saying that it could not "modify the sentence" for his previous convictions.

[28] At the request of the delegations of Colombia and Ecuador, the Permanent Council of the Organization of American States met on 9 and 10 April to discuss the raid and its implications.

Mexico's Alicia Bárcena sought backing from the other countries for the planned filing of an action at the International Court of Justice, and consideration was given to a summit of the bloc's heads of state and government.

In the application, Mexico requested provisional measures to protect the integrity of the abandoned embassy and that Ecuador's membership in the United Nations be suspended until a public apology is given.

[37][38] The ICJ declined Mexico's request for provisional measures in May 2024, finding that they were not warranted by the circumstances, because Ecuador had already pledged to protect Mexican diplomatic premises.

[39][36] The embassy raid provoked what The Guardian newspaper described as "an unusually intense outpouring of outrage from across the political spectrum in Latin America".
