Gretchen Whitmer has signed new legislation into law that will overhaul the state’s parole and probation system. “The package of legislation included three very important reforms to supervision, to probation and to parole,” Haney said. Those laws aim to reshape the state’s probation and parole system and help thousands of people. What these reforms do is that they seek to make probation and parole more just and more effective,” Haney said. The new set of laws will reduce adult felony probation sentences in Michigan from five years to three years and prevent endless extensions on misdemeanor and felony probation terms.
