In People v. Cao, No. 373185 (Mich. Ct.

Ackerman authored McCallum v. M-97 Auto Dealer, Inc., No. 367630 (Mich. Ct. App. Sept. 30, 2025), which involved a used-car dealership that misrepresented the true mileage of a vehicle. The opinion opened with and included quotations from Roald Dahl’s Matilda. Ackerman also authored Nonhuman Rights Project, Inc. v. DeYoung Family Zoo, LLC, No. 369247 (Mich. Ct. App. Oct. 17, 2025), in which the Court rejected a habeas corpus petition filed on behalf of seven chimpanzees held at a private zoo in Michigan’s Upper Peninsula. The Court held that chimpanzees are not “persons” entitled to personal-liberty rights under Michigan law and explained that “No exception exists for ‘intelligent’ animals, which in any event has no natural stopping point.” Selected writings
