(a) As outlined in the Budget Act of 2018, it is anticipated that all California inmates will be returned from out-of-state contract correctional facilities by February 2019.  To the extent that the adult offender population continues to decline, the Department of Corrections and Rehabilitation shall begin reducing private in-state male contract correctional facilities in a manner that maintains sufficient flexibility to comply with the federal court order to maintain the prison population at or below 137.5 percent of design capacity.  The private in-state male contract correctional facilities that are primarily staffed by non-Department of Corrections and Rehabilitation personnel shall be prioritized for reduction over other in-state contract correctional facilities.
