Michigan State Police have removed more than 20,000 people from the state’s sex-offender registry after the Michigan Supreme Court barred the state from retroactively extending registration requirements for people whose relevant crimes occurred before July 1, 2011.
The agency said about 43,000 people were actively registered or required to register when the court issued its September 9 order. By September 11, more than 20,000 had been removed, according to the official statement. State Police cautioned that the totals could change as staff continue reviewing records.
The decision does not erase convictions or seal court files. It changes whether affected people must remain in the state-maintained registration system under requirements added or extended after their offenses. The public registry typically displays identifying information drawn from registrants and public records, including photographs, addresses and conviction information, according to a registry review published Tuesday.
What the court decided
In its September 9 order, the Michigan Supreme Court concluded that the 2021 version of the Sex Offenders Registration Act could not be applied to lengthen registration obligations for conduct predating July 1, 2011. The court treated that retroactive extension as unconstitutional punishment under the prohibition on ex post facto laws.
The ruling focuses on timing. It does not categorically eliminate registration for offenses committed on or after the 2011 cutoff, and it does not prevent the state from enforcing requirements that were lawfully attached to a conviction. Eligibility for removal therefore depends on the date and legal history connected to each record, not merely on how long a person has appeared in the database.
Michigan’s registration statute directs State Police to maintain both a law-enforcement database and a separate public website. Col. James Grady II, the department’s director, emphasized that the agency did not initiate the legal change but is responsible for carrying out the court’s order. He directed policy concerns and proposals to the Legislature.
Practical consequences
For the public, the immediate effect is a substantially smaller searchable registry. For people removed under the ruling, registration and reporting duties tied solely to the invalid retroactive extension should end, although separate probation, parole or court-ordered conditions may still apply in individual cases.
State Police urged anyone who believes the remaining registry contains an error involving an offense committed on or after July 1, 2011, to contact the registry unit or the local law-enforcement agency associated with the listed address. The department has not announced a final completion date for its record-by-record review.
The Legislature may examine the statute in response, but any revision would have to account for the constitutional limit identified by the court. Until then, the State Police review and the September 9 order control how older registration periods are handled.
