MI HB4508

Adds a new sentencing exception (section 769.25b) to multiple felony provisions in Michigan's penal code that currently impose mandatory life without parole sentences, potentially allowing alternative sentencing for certain offenders

Applies to serious offenses including drug/medicine adulteration causing death, terrorism, first-degree murder, use of harmful biological/chemical/radioactive substances, explosives offenses, and poisoning food/water supplies

Modifies first-degree criminal sexual conduct law by raising the age threshold for mandatory life without parole from 18 years old to 21 years old for repeat offenders who victimize children under 13

Updates gendered language throughout the penal code sections (changing "his or her" to "the person's" or similar neutral terms)

Takes effect only if House Bill No. 4506 is also enacted into law (tie-bar provision)
