In February 2022, Excélsior counted 763 changes to Mexico’s Constitution of 1917, made through more than 250 reform decrees. Four articles, 73, 123, 27 and 89, had been changed 144 times between them.
The changes continued. In February 2026, Crónica cited the constitutional scholar Edgar Corzo, who counted 18 reform decrees between October 2024 and December 2025.
In March 2021, President López Obrador gave the army one year to finish the new Felipe Ángeles International Airport (AIFA) at Santa Lucía. “Yo le voy a pedir al general Vallejo que procuremos inaugurarlo el 21 de marzo del 2022” (I am going to ask General Vallejo that we try to inaugurate it on March 21, 2022), he said, according to Excélsior.
The airport opened on March 21, 2022, after 884 days of construction, according to Expansión. At the time of the opening, few airlines had committed to flights from it. (Video in Spanish.)
The airport opened on the date the president had named a year earlier.
Mexico’s federal government pays many of its employees bonuses for punctuality. In 2018, Mexico News Daily reported, citing data that El Universal obtained through transparency requests, that federal employees received 40.7 billion pesos in punctuality bonuses between 2012 and 2017. Most of it went to staff of the social security institute IMSS.
In 2017, El Universal’s English edition had given a different figure: 34.7 billion pesos for the years 2013 to 2016. The two counts cover different periods.
Article 102, section B, of the Constitution creates the human rights commissions. They “formularán recomendaciones públicas, no vinculatorias” (will issue public, non-binding recommendations). An authority that does not accept a recommendation must “fundar, motivar y hacer pública su negativa” (give the legal grounds and reasons for its refusal and make it public). At the commission’s request, the Senate may call the responsible officials to account.
On February 18, 2025, the parliamentary gazette published a resolution proposed by deputies of the PRI in the Chamber of Deputies about the levels of lead and arsenic in Monterrey.
Its first point reads: “La Cámara de Diputados del honorable Congreso de la Unión exhorta respetuosamente a la Secretaría” (The Chamber of Deputies of the honorable Congress of the Union respectfully urges the Ministry) of Environment and Natural Resources and the government of Nuevo León to investigate. Resolutions of this kind are called puntos de acuerdo.
In March 2020, at the start of the pandemic, the federal government introduced Susana Distancia. Her name echoes sana distancia, “healthy distance.” Expansión described her as “una ‘heroína’ que explica paso a paso las medidas de salud básicas” (a “heroine” who explains the basic health measures step by step). (Video in Spanish.)
Two days later, Expansión called her the heroine with which the federal government hoped to slow the spread of COVID-19, in the national campaign of healthy distance, the Jornada Nacional de Sana Distancia.
On March 19, 2020, President López Obrador ruled out a curfew. “No voy a decir ‘he decretado que haya limitación a las libertades, toque de queda, nadie salga a las calles'” (I am not going to say “I have decreed limits on freedoms, a curfew, nobody goes out into the streets”), he said. In April 2020, the undersecretary of health, Hugo López-Gatell, said that there was no legal basis for using public force.
On November 16, 2020, López Obrador again rejected coercive measures. “Lo mejor es hacer conciencia en la gente y tenerle confianza al pueblo” (The best thing is to raise people’s awareness and to trust the people), he said.
Mexico’s tax authority, the SAT, sends taxpayers who may have omitted taxes a carta invitación, a letter of invitation. In October 2014, it sent about 600,000 such letters to people who had received cash deposits in their bank accounts and had not declared them. The letters invited them to regularize their tax situation.
According to UnoTV, the taxpayers’ ombudsman, Prodecon, stresses that the letter “no es una resolución definitiva” (is not a final decision). The Colegio de Contadores Públicos de México still warns that taxpayers should answer it, to avoid a formal audit and possible fines.
Autos chocolate are cars brought into Mexico from the United States without legal import papers. On January 19, 2022, the federal government published a decree to regularize them. The procedure cost 2,500 pesos and was to be open “hasta el 20 de julio de 2022” (until July 20, 2022). (Video in Spanish.)
The program went on well past that date. In January 2026, La Razón reported finance ministry figures: “se han legalizado un total de 2 millones 987 mil 839 vehículos” (a total of 2,987,839 vehicles have been legalized), with 7,302 million pesos collected.
In May 2019, Margarita Ríos-Farjat, head of the tax administration SAT, gave the total of taxes forgiven between 2007 and 2018. At current value, the condonations came to 400,902 million pesos, for 153,530 taxpayers. On May 20, 2019, President Andrés Manuel López Obrador signed a decree ending them. (Video in Spanish.)
On March 6, 2020, the Diario Oficial published a reform of Article 28 of the Constitution “en materia de condonación de impuestos” (on the forgiveness of taxes). The article now lists the condonation of taxes among the things it prohibits.
