Bill Summary · HB 4018

Summary — HB 4018 (Probate Code amendment; MCL 712A.16)

Status: Referred to Committee on Civil Rights, Judiciary, and Public Safety
Introduced: March 7, 2025 (House) — Passed House March 11, 2025; referred to committee March 13, 2025
Primary sponsor: Rep. Mike Mueller (House Fiscal Agency analysis prepared)
Effective date if enacted: 90 days after enactment

Purpose

HB 4018 amends section 16 of the Probate Code (MCL 712A.16) to create a limited exception to the current prohibition on transporting juveniles together with adult offenders. The bill is intended to allow law enforcement more flexibility to transport older juveniles together with certain adult arrestees under narrowly defined conditions.

Key provisions

  • Adds a new exception (subsection (7)) allowing a juvenile under 18 to be transported with an adult offender only if all of the following are met:
    • The juvenile is at least 16 years old.
    • The adult is not more than 25 years old.
    • The juvenile and adult are taken into custody at the same time.
    • They are taken into custody for the same offense or both occupied the same vehicle when the offense was committed.
    • The juvenile is taken directly to the appropriate location and separated from the adult at the earliest available time, consistent with the existing requirement that juveniles not be confined or mingled with adult criminals.
  • Leaves intact other protections in subsection (1) that prohibit confining, imprisoning, transporting, or mingling juveniles with adult criminals, and preserves the court’s limited authority to place certain 15‑year‑olds in adult jails under specified conditions.

Who is affected

  • Juveniles aged 16–17: may, under limited circumstances, be transported together with an adult arrestee.
  • Adult arrestees aged up to 25: may be transported with qualifying juveniles when criteria are met.
  • Law enforcement agencies and county detention/transport operations: will have an additional, narrowly tailored transport option.
  • Counties: potential (indeterminate) reductions in transportation and child care fund costs if separate juvenile transport is avoided.

Background and fiscal impact

  • This bill reintroduces language from a previously passed but vetoed bill (House Bill 4887, 2021–22 session).
  • House Fiscal Agency reports no significant fiscal impact on the Department of Health and Human Services. Counties may realize indeterminate transportation savings depending on usage.

Practical effect and safeguards

The change is narrowly tailored by age limits, simultaneous custody, same-offense/vehicle connection, and requirement that juveniles be taken directly to the appropriate facility and separated as soon as possible—preserving the general policy that juveniles should not be mingled or detained with adult offenders.
