What MacArthur Justice Center does

The MacArthur Justice Center (MJC) is a 501(c)(3) public interest legal organization founded in 1985 by the MacArthur family in honor of J. Roderick MacArthur, the pioneer of the John D. & Catherine T. MacArthur Foundation's 'genius' grants. Headquartered in Chicago, Illinois, MJC pursues impact litigation and systemic reform on criminal justice and civil rights issues, including wrongful convictions, police and prosecutorial misconduct, solitary confinement, cash bail, immigrants' rights, voting rights, and the right to protest. It operates four regional offices (Illinois, Louisiana, Mississippi, Washington D.C.) following the May 2026 closure of its St. Louis office, with a Supreme Court & Appellate Program that litigates cases nationwide in federal and state appellate courts, including landmark U.S. Supreme Court victories such as Garza v. Idaho, Rasul v. Bush, and Thompson v. Clark.

MJC's core offerings are organized around three internal programs — the Supreme Court & Appellate Program (SCAP), the National Parole Transformation Project (NPTP), and clinical legal education partnerships with Northwestern, Harvard, and the University of Mississippi — alongside specialized initiatives such as the Mississippi Forensic Navigators program. The organization does not develop proprietary technology; its operational infrastructure consists of a standard nonprofit website, EveryAction-based email and donation platform, social media accounts, and a public litigation tracker. It has recovered over $100 million in civil cases arising from wrongful convictions, including a $50 million jury verdict that is the largest wrongful conviction financial award in U.S. history.

MJC's business model is that of a nonprofit public interest law firm: services are provided free of charge to clients, and revenue derives from individual donations, foundation grants (notably the founding MacArthur family), institutional funders, and the occasional share of legal settlements or attorney's fees from successful civil litigation. Clients are individuals harmed by the criminal justice system rather than paying customers, and go-to-market is community-led — built through coalition partnerships with organizations such as the ACLU, Southern Poverty Law Center, Equal Justice Initiative, MALDEF, and National Immigrant Justice Center, as well as co-counsel arrangements with elite law firms including Latham & Watkins, Williams & Connolly, Covington & Burling, Orrick, and Akin. Outreach and awareness are driven by earned media coverage, the MJC blog, newsletter subscriptions, events such as the 40th anniversary gala, and teach-in series.
