Brown v. Plata

Background

Two federal class actions challenged California’s prison medical and mental health care. Coleman covered prisoners with serious mental illness; Plata covered prisoners with serious medical needs. The record showed prisons at nearly double design capacity, unsafe and unsanitary conditions, staff shortages, long waits for care, and preventable deaths. After prior remedies failed, a three-judge court under the Prison Litigation Reform Act (PLRA) ordered California to cut its systemwide population to 137.5% of design capacity within two years and to submit a compliance plan.

Reasoning

The central question was whether the PLRA permitted a court-ordered population limit and whether that limit was necessary to remedy ongoing Eighth Amendment violations. The Court held a three-judge court may act only after less intrusive relief has failed and only if clear and convincing evidence shows crowding is the primary cause and no other remedy will work. The Court found those conditions met, concluded the 137.5% cap was narrowly tailored, and affirmed the order while noting the State may seek modification.

Real world impact

The ruling can require releases, transfers, sentencing or parole changes to remove thousands of prisoners—possibly tens of thousands—if capacity is not increased. It forces state officials to choose how to comply and to reallocate prison budgets, health staffing, or construction. The decree is subject to future modification; implementation must consider public safety.

Dissents or concurrances

Justices Scalia and Thomas dissented, warning that federal courts lack authority to run state prison systems and that the PLRA and constitutional limits bar such mass releases. Justice Alito (joined by the Chief Justice) stressed the court’s refusal to admit recent evidence and argued the order underweights public safety risks.
