Yasmín Esquivel Mossa

Esquivel has expressed interest in becoming the first female president of the SCJN, whose election will be held in January 2023.

On April 20, 2022, Esquivel blocked the delivery of the investigation report of alleged acts of illicit financing by Pío López Obrador, brother of the president of Mexico, to the National Electoral Institute. The report was requested by the institute to the Attorney General of Mexico following a ruling by the Electoral Tribunal of the Judiciary of the Federation to determine the situation of Pío, who the previous year gained notoriety due to the leaking of a 2015 video in which David León Romero [es], a coordinator from the Ecologist Green Party of Mexico, gave him cash without a specific origin for "the movement". Esquivel determined that the report could not be released because doing so would violate Pío's human rights, including his right to privacy.

In December 2022, Guillermo Sheridan, scholar and researcher at UNAM, presented an investigation denouncing that Esquivel's thesis copied verbatim several segments of another student's thesis published the previous year. According to the investigation, Esquivel's thesis Inoperancia del sindicato de los trabajadores de confianza del Artículo 123 Apartado A ("Inoperability of the union of workers of trust under Article 123 Section A"), presented in September 1987, copies various pages, texts, graphs, grammar errors and sections (such as its table of contents, introduction, and conclusion) of the thesis presented by Édgar Ulises Báez Gutiérrez in July 1986 and titled Inoperancia de los sindicatos en los trabajadores de confianza del Artículo 123 Apartado "A" ("Inoperability of unions for workers of trust under Article 123 Section 'A'"). She denied the accusation, calling the report "totally false". Authorities of the Facultad de Estudios Superiores Aragón announced that they would investigate the report in detail and that if the plagiarism was confirmed, they would act in accordance with institutional regulations. Afterwards, UNAM acknowledged that there was "a high level of coincidence" in both documents and that the university will determine Esquivel's status.

Esquivel was selected in 2019 to replace minister Margarita Beatriz Luna at the National Supreme Court of Justice (SCJN). President Andrés Manuel López Obrador nominated her and she was ratified by the Senate of the Republic. Her selection engendered some disapproval from opposition parties as she is married to José María Riobóo, the president of Grupo Riobóo [es], one of the main advisers of president López Obrador on infrastructure issues and one of his main contractors during his tenure as head of government of Mexico City between 2000 and 2005, stating that the minister could have potential conflicts of interest. In this regard, Esquivel said that prior to meeting Riobóo, she already had her own professional career as a federal and local magistrate, that she should not be seen as "the wife of" anyone and in the event of any conflict of interest related to Riobóo, she would excuse herself immediately.

President López Obrador expressed that "any error, any anomaly, committed by Minister Yasmín when she was a student, when she presented her undergraduate thesis, is infinitely less than the damage caused to Mexico by [Enrique] Krauze and the man making the accusation, Sheridan", and that the investigation was carried out to attack his government. Esquivel later shared letters of support and defense of her career from various lawyers and professors, including one from Martha Rodríguez, her thesis advisor. Rodríguez considered that the investigation arose from a "misogynist conspiracy" after Esquivel announced her interest in becoming the first woman to preside over the SCJN. Subsequent investigations determined that Rodríguez was an advisor for both theses and that there are at least eight other theses with similar problems. In addition, there is a 1993 thesis (advised by another professor) and a 2010 thesis (advised by Rodríguez) with identical fragments and similar wording to that of Báez.

Yasmín Esquivel Mossa studied law at the Escuela Nacional de Estudios Profesionales (ENEP) Aragón of the National Autonomous University of Mexico (UNAM) and earned a licentiate in 1987 and a Doctor of Law degree from the Complutense University of Madrid and the Universidad Anáhuac, which she obtained in 2000. She also did postgraduate work in administrative law and fiscal law in the Mexican financial system at Panamerican University.

As a public official, she began her career in the legal and government subdelegation of the mayor's office in Coyoacán in 1985. She was a civil servant in the office of the Attorney General of the Federal District and in the Institute of the National Housing Fund for Workers. In the legal field, Esquivel served as study and account secretary of the presidency of the Superior Agrarian Court from 2000 to 2004. She was a magistrate of the Superior Chamber of the Court of Administrative Litigation in 2009, and was its president from 2012 to 2015.

On Christmas Day, Esquivel announced a complaint for plagiarism with the prosecutor's office, affirming that she began writing her thesis in 1985 and that she will continue with the process to become president of the SCJN.

Yasmín Esquivel Mossa (born September 15, 1963) is a Mexican lawyer and public official who serves as a minister of the Supreme Court of Justice of the Nation for the period 2019–2034. Esquivel graduated with a law degree in 1987 but she claims that her thesis was plagiarized by Édgar Ulises Báez Gutiérrez who graduated a year before her and who according to the National University submitted the original thesis which was later plagiarized by Esquivel. Since then, she has served in positions such as account secretary of the presidency of the Superior Agrarian Court or magistrate and president of the Superior Chamber of the Court of Administrative Litigation.
