End Solitary Confinement Act

119th Congress Introduced Jul 28, 2025

Summary

What This Bill Does

This bill bans solitary confinement in all federal prisons, immigration detention centers, and contracted facilities. It requires that all incarcerated people have at least 14 hours per day of out-of-cell congregate time, including 7 hours of structured programming (education, mental health, job training). The bill creates an independent community monitoring body to oversee compliance.

Who Benefits and How

Incarcerated people in federal facilities benefit directly by gaining protection from solitary confinement and guaranteed access to programming and human interaction. Civil rights and prisoners' rights organizations benefit as the bill creates new legal avenues for lawsuits related to solitary confinement. Community organizations and advocacy groups benefit through the establishment of a monitoring body composed of formerly incarcerated people and advocates.

Who Bears the Burden and How

Federal corrections agencies (Bureau of Prisons, ICE, CBP, US Marshals) face significant compliance burdens to restructure their facilities and provide 14+ hours of daily programming. Private prison contractors operating federal facilities must meet the same standards. State and local governments receiving Byrne JAG grants face up to 10% funding cuts if they do not comply with anti-solitary confinement standards.

Key Provisions

  • Bans solitary confinement except in narrow emergency situations (max 4 hours immediately, 12 hours per week)
  • Mandates 14 hours/day of out-of-cell congregate time including educational, mental health, and vocational programming
  • Creates independent community monitoring body of 15+ members including formerly incarcerated people
  • Reduces Byrne JAG grant funding by 10% for non-compliant states and localities
  • Expands prisoners' ability to sue for mental/emotional injury from solitary confinement
