Sonia Maria Sotomayor was born in the Bronx in 1954 to Puerto Rican parents, was raised by her widowed mother in a housing project, and was diagnosed with diabetes as a child. She rose through Princeton and Yale Law School to become a New York prosecutor, a commercial litigator, and a federal trial and appellate judge. In 2009 Barack Obama named her to the Supreme Court, the first Latina and first Hispanic justice in its history.
Sotomayor has become the passionate conscience of the Court's liberal wing — the justice who writes most fiercely about race, policing, and the human beings on the losing end of the Court's decisions. A former trial judge attentive to facts and consequences, she is best known for her dissents. In Utah v. Strieff she protested the erosion of protections against arbitrary police stops; in Schuette v. BAMN she answered colorblind constitutionalism with the insistence that the nation speak openly about race; and in Trump v. United States she warned that broad presidential immunity places the president 'above the law,' closing 'with fear for our democracy, I dissent.' Her memoir, My Beloved World, was a bestseller. She continues to serve.

Read the opinion →Sonia Sotomayor is the first Latina and the first Hispanic justice of the Supreme Court, and in her years on the bench she has become the passionate conscience of its liberal wing — the justice who writes most fiercely about race, policing, and the human beings on the losing end of the Court's decisions. Raised by a widowed mother in a Bronx housing project, diagnosed with diabetes as a child, she rose through Princeton and Yale Law to become a prosecutor, a corporate litigator, and a federal judge before Barack Obama named her in 2009 to succeed David Souter (§105). Her 2013 memoir, My Beloved World, told that improbable story with unusual candor and became a bestseller. On the Court she is best known for her dissents — in Utah v. Strieff on police stops, in the affirmative-action cases, and in Trump v. United States on presidential immunity, where she closed 'With fear for our democracy, I dissent.' A former trial judge attentive to facts and consequences, she speaks, more than any colleague, to and for those the law can overlook. Begin with the memoir, then read the great dissents that define her voice.
The Bookshelf
Sotomayor's memoir, and the indispensable introduction to the justice and the person. Written before she had served long on the Court, it recounts her Bronx childhood, her mother's sacrifices, her diabetes, her awakening as a student, and her path through the law — with a candor rare in a sitting justice. Warm, vivid, and inspiring without being sentimental, it explains the empathy and attention to lived experience that mark her jurisprudence, and it remains a bestseller for good reason. Alfred A. Knopf. Pair it with her children's-book and civics work for the fuller picture of her public mission.
The best biography — the veteran Court journalist Joan Biskupic on Sotomayor's rise from a Bronx housing project to the Court, and on the politics of the first Latina justice's appointment. The essential complement to her own memoir. Sarah Crichton Books.
An accessible earlier biography, strong on the Puerto Rican family, the childhood diabetes, and the Princeton-and-Yale ascent. Berkley Books.
Her most celebrated dissent, and a landmark of the modern debate over policing. When the Court allowed evidence from an unlawful stop because the officer later found an outstanding warrant, Sotomayor objected that the ruling licensed exactly the kind of arbitrary stops that fall hardest on communities of color — writing, in a passage that broke from the case record into direct address, that such treatment tells people 'you are not a citizen of a democracy but the subject of a carceral state.' Drawing on scholarship and lived reality, it is the fullest statement of her concern for the dignity of those most exposed to state power. Read it as the voice that sets her apart.
Sotomayor's major statement on race and the Constitution, delivered when the Court upheld a state ban on affirmative action. In a long dissent read in part from the bench, she answered the color-blind constitutionalism of her conservative colleagues with the insistence that 'the way to stop discrimination on the basis of race is to speak openly and candidly on the subject of race' — a direct rejoinder to Chief Justice Roberts's (§109) famous formula. Personal and unapologetic, it framed the argument the Court would return to in the 2023 admissions cases. Read it as her answer to colorblindness.
Her gravest dissent, from the decision granting former presidents broad immunity from criminal prosecution for official acts. Warning that the ruling placed the president 'above the law' and made him 'a king,' she catalogued the dangers she saw for accountability and self-government and ended, departing from the customary 'respectfully,' with the words 'With fear for our democracy, I dissent.' Read it as the culmination of her role as the Court's most urgent dissenting voice, and as a document in the era's argument over presidential power and the rule of law.

Where the Papers Are Kept
Sotomayor continues to serve, and her judicial papers are not open to researchers. Her life before the Court is documented with unusual fullness in her own memoir, and her jurisprudence in the Court's published opinions; her earlier service is recorded in the files of the U.S. District and Circuit Courts on which she sat.

Ideas for Further Research
- The dissent as empathy. Sotomayor's most powerful opinions break from doctrinal analysis into direct address, insisting the Court reckon with how its rulings land on real and often vulnerable people. Study her use of narrative and moral appeal — in Strieff, in the immigration and death-penalty cases — and ask what such writing accomplishes that conventional legal reasoning cannot, and whether emotional force strengthens or weakens a dissent's claim on the future.
- The 'wise Latina' and the meaning of experience. Before her confirmation Sotomayor suggested that a 'wise Latina' might sometimes reach a better conclusion than a judge without her life experience — a remark that drew fierce criticism. Set it against her actual jurisprudence and against the ideal of the detached, experience-blind judge, and ask what role a justice's background legitimately plays in judging, and how candor about it should be received.
- Speaking openly of race. Against the colorblind constitutionalism of the Court's majority — 'the way to stop discrimination on the basis of race is to stop discriminating' — Sotomayor argues that the Constitution permits, and history requires, candor about race and its remedies. Trace this divide from Schuette through the 2023 admissions cases, and ask which vision better serves equal protection's promise in a society still shaped by its racial past.
