Final answer:
The statement that parole boards no longer exist within the federal justice system is true, following the abolition of the federal parole system by the Sentencing Reform Act of 1984.
Step-by-step explanation:
The use of parole boards no longer exists within the federal justice system. This statement is True. The federal parole system was abolished with the enactment of the Sentencing Reform Act of 1984, which took effect in 1987. This act replaced parole with a determinate sentencing system, where federal prisoners can only reduce their time in custody through good behavior credits, not parole.
The law was part of a larger federal effort to create a more predictable and consistent sentencing structure.
As a result, the federal justice system currently operates without parole boards, which formerly had the authority to release inmates on parole based on factors such as good behavior, rehabilitation efforts, and the likelihood of re-offending. However, parole boards still exist and function at the state level in various jurisdictions, where they continue to play a role in the parole process for eligible state prisoners.
