Ketanji Brown Jackson was born in Washington, D.C., in 1970 and raised in Miami by parents who had come of age under segregation. A Harvard College and Harvard Law graduate, she served as a federal public defender — the first justice with that experience since Thurgood Marshall (§96) — and as vice-chair of the U.S. Sentencing Commission and a federal trial and appellate judge. In 2022 Joe Biden named her to succeed her former boss Stephen Breyer (§108), and she was confirmed 53–47, the first Black woman on the Supreme Court of the United States.
In her first terms Jackson made an immediate mark as a forceful voice of the Court's liberal minority. In the 2023 Harvard and North Carolina admissions cases she wrote a passionate solo dissent arguing that a colorblind reading of the Constitution ignores the entrenched effects of history — 'deeming race irrelevant in law does not make it so in life.' In Trump v. United States she wrote separately to warn that broad presidential immunity creates a 'law-free zone' around the most powerful office in the country. Attentive, from her years as a public defender, to how legal rules operate in the real world, she has quickly established herself as a major dissenting voice. Her memoir, Lovely One, was a bestseller. She continues to serve.

Read the opinion →Ketanji Brown Jackson is the first Black woman to serve on the Supreme Court of the United States, and, since 2022, a forceful voice of its liberal minority. The daughter of educators, a Harvard College and Harvard Law graduate, she brought to the bench a background unusual among modern justices — service as a federal public defender, the first justice with that experience since Thurgood Marshall (§96), and years on the U.S. Sentencing Commission and the federal trial and appellate benches. Appointed by Joe Biden to succeed Stephen Breyer (§108), whom she had clerked for, she was confirmed 53–47 after hearings in which her sentencing record was sharply contested. In her first terms she made an immediate mark, most notably in a solo dissent in the 2023 Harvard and North Carolina admissions cases arguing that a colorblind reading of the Constitution ignores the entrenched effects of history, and in dissents on presidential power and the Court's emergency docket. Her 2024 memoir, Lovely One, tells her story in her own words. Begin there, then read the great early dissents that have quickly established her voice.
The Bookshelf
Jackson's bestselling memoir, and the natural introduction to the newest justice — its title the English meaning of her West African name, Ketanji Onyika. She writes of her parents' generation crossing from segregation into opportunity, her path through Harvard, her years as a public defender and judge, and the improbable arrival at the Court, weaving family history with the making of a jurist. Warm, candid, and reflective, it explains the perspective — especially her attention to the criminal-justice system from the defense side — that she brought to the bench. Random House.
Jackson's landmark early dissent, in the case ending race-conscious college admissions. Answering the majority's colorblind reading of the Equal Protection Clause, she argued — with a wealth of historical and economic detail — that ignoring race does not undo its entrenched, measurable effects, and that 'deeming race irrelevant in law does not make it so in life.' Personal, data-rich, and unsparing, it announced her as a major dissenting voice and framed the argument against colorblind constitutionalism for the years ahead. Read it beside the majority and Sotomayor's dissent (§111) as the fullest liberal answer on race and the Constitution.
Jackson's separate dissent from the decision granting former presidents broad immunity for official acts, written to press a distinct point: that the majority had created, in her words, a 'law-free zone' around the most powerful office in the country, exempting the president from the accountability that governs everyone else. Focused on the structural danger of placing anyone beyond the reach of the criminal law, it complements Sotomayor's dissent (§111) and shows Jackson's characteristic attention to how legal rules operate in the real world. Read it as a document in the era's argument over presidential power and equality before the law.
Joan Biskupic's account of the conservative supermajority supplies the institutional context for Jackson's arrival — a justice joining a Court whose six-to-three balance means her most important work, at least for now, is done in dissent. Well sourced and readable, it explains the dynamics she stepped into and the stakes of her role as one of three liberals on a Court moving decisively rightward. William Morrow. Read it alongside her memoir for both the personal and the institutional story.

Where the Papers Are Kept
Jackson is the newest justice and continues to serve; there is no archive of her judicial papers. Her life and outlook are documented in her own memoir, and her jurisprudence in the Court's published opinions and her early dissents; her prior service is reflected in the records of the U.S. Sentencing Commission and the federal district and circuit courts on which she sat.

Ideas for Further Research
- The public defender's perspective. Jackson is the first justice since Thurgood Marshall (§96) to have represented indigent criminal defendants, and she has said that experience shapes how she sees the law. Study whether and how a defense background surfaces in her opinions — on sentencing, criminal procedure, and the rights of the accused — and ask what range of professional experience the Court gains, and has often lacked, in its members.
- History against colorblindness. Jackson's Harvard dissent mounts a historically grounded case that the Constitution permits, and the nation's past requires, attention to race in remedying entrenched inequality — the sharpest recent answer to the majority's colorblind reading. Set her argument beside Sotomayor's (§111) and against the Roberts (§109) and Thomas (§106) view, and ask which reading of the Fourteenth Amendment better fits its history and its purpose.
- The power of the new dissenter. Joining a six-to-three Court, Jackson's most consequential early work is necessarily in dissent, addressed to lower courts, to Congress, and to the future. Study how a junior justice builds influence from the minority — through the force of her writing, her questioning at argument, and the arguments she plants for later — and ask what her first terms suggest about the role she may come to play over what could be decades on the Court.
