JRI Year: 2017



In 2015, Montana’s prisons were at capacity due to an 11 percent increase in the prison population between 2008 and 2015. The prison population was projected to grow another 13 percent by 2023, requiring at least $51 million in new spending. Additionally, the statewide jail population rose 69 percent between 2011 and 2013 and many jails were over capacity. To address these challenges, state leaders began using a JRI approach with technical assistance from the CSG Justice Center in 2015. The Montana Commission on Sentencing—which includes commissioners from all three branches of government, policymakers, and other stakeholders—met multiple times between September 2015 and October 2016 to review analyses and develop policy options to ease capacity issues and reduce recidivism.


Of 12 bills recommended by the Commission on Sentencing, Montana enacted nine pieces of legislation. Senate Bills 59, 60, 62, 63, 64, 65, 67, Senate Resolution 3, and House Bill 133 codify the JRI policy framework developed by the Commission on Sentencing. Signed into law in the spring of 2017, these policy and practice changes allow more discretion regarding the length of incarceration for people sanctioned for low-level violations of the terms of their supervision, prioritize supervision resources for people who are most likely to reoffend, and help counties reduce jail populations.1


By adopting these policies, Montana avoided spending millions of dollars to build new correctional facilities between 2018 and 2023. This allowed the state to reinvest those savings in strategies designed to reduce recidivism and increase public safety. Those funds supported developing a pretrial grant program, hiring additional supervision officers, transitioning the parole board from a part-time volunteer board to a full-time professional board, and developing a supportive housing grant program.
