The unanimous Sept. 9 decision also denied any legal rights to the unborn, with the decision stating, "For the court, it is inadmissible to establish that the embryo and fetus deserve the same legal protection as born persons."
The court also said in its ruling, "Although the product of pregnancy deserves protection that increases over time as the pregnancy progresses, this protection cannot ignore the rights of women and pregnant people to reproductive freedom and, in particular, their right to interrupt the pregnancy in certain cases."
The decision concerning Sinaloa state followed a unanimous Sept. 7 ruling in which the court ruled invalidated sections of a law in northern Coahuila state.
The Coahuila law imposed sentences of up to three years in prison for women terminating pregnancies; observers say the court decision sets precedent and will lead to decriminalization across the country. The decision also removed criminal sanctions for abortion providers.
The motion approved in the court, according to Justice Norma Piña Hernández, "concludes there are no public reasons with scientific support that allow equating the embryo with a person with rights."
She continued, "Prohibiting abortion in these circumstances ... implies giving excessive value to the state's interest in protecting the development of the pregnancy in the face of the intense impact carrying an unwanted pregnancy represents for the autonomy of women when there are not the vital conditions to do so properly."
After the court decision, the bishops' conference tweeted, quoting from a conference document published Aug. 12: "Those of us convinced of the value of life have no need for a murderous law such as the one that is being approved ... We hope that your option for life is not conditional on an ideology, rather is motivated by faith, hope and love."
In a document issued Sept. 8, the bishops said: "No woman should be forced to make the dramatic decision to resort to the practice of abortion, a situation that in a large number of cases leaves a deep effect of pain. In this sense, we are aware that prison is not a solution to the problems faced by women who have an abortion and rather can lead to their re-victimization."
The statement continued, "We warned with serious concern that the reasoning used is based on parameters of interpretation that -- under the appearance of progressivity -- translates into 'constitutionalizing of the right to choose.'"
The bishops also called for "a renewed commitment ... to guarantee the protection of women in all circumstances, gestating or not, while respecting the human right to life, both of the mother along with the conceived not yet born."
The court decision in Mexico, the country with the world's second-highest number of Catholics, continued a trend in Latin America toward the decriminalization of abortion. Women throughout the region have taken to the streets to protest issues of gender violence and abortion access in recent years.
In December 2020, Argentina decriminalized abortion during the first 14 weeks of pregnancy. Mexico City decriminalized abortion in 2007, a move upheld by the Supreme Court the next year, and three of Mexico's 32 states have followed its lead. More than half of Mexico's states have approved constitutional prohibitions on abortion.
The Supreme Court ruled Mexico City's law constitutional based on the state being able to set local health policy, according to Rebeca Ramos, director of the nongovernmental Information Group on Reproductive Choice. This time, she said, the court "got the heart of the matter" and ruled on questions pertaining to the right to access abortion.
"Never again should a woman or a gestating person be criminally prosecuted. Today the threat of prison and the stigma that weighs on people who decide to freely interrupt their pregnancy is banished," said Justice Luis María Aguilar, whose motion to approve decriminalization was debated in the court.
Mexican President Andrés Manuel López Obrador has not pushed for decriminalizing abortion, saying other issues take priority -- though members of his Morena party have approved decriminalization bills since 2019 in the states of Oaxaca, Hidalgo and Veracruz. He declined to give an opinion on the court case at his Sept. 7 news conference.
"We have Supreme Court justices, who are more liberal, (and) a broad and active feminist movement," said Bárbara González, a political analyst in Monterrey. "The justices want to win points with the people," she added, but also show independence in the face of accusations of submission to pressure from the president.
Polling on abortion shows a generational divide in Mexico, with a slight majority of people under the age of 50 supporting decriminalization. A poll by the newspaper El Financiero found 53% of Mexicans opposed decriminalization, while 45% were in favor.
