OhioState v. McClain

October 8, 2026

The court held that the State presented sufficient evidence to support McClain’s conviction for substantial-impairment rape because the victim’s memory gap, the DNA evidence, and other circumstantial evidence supported the required elements, including reasonable cause to believe she was impaired.

OhioIn re A.S.

October 7, 2026

The court held that when a juvenile court has returned legal custody of a dependent child to a natural parent and closed the dependency case, it cannot later award custody to a nonparent without first finding that the parent has become unsuitable since custody was restored.

October 1, 20262026 Ohio 3814

October 1, 20262026 Ohio 3813

September 29, 20262026 Ohio 3771

The court held that Bradley did not establish plain error from the trial court’s failure to give an unrequested instruction concerning transferred self-defense.

OhioState ex rel. Ellis v. Dept. of Rehab. & Corr.

September 29, 20262026 Ohio 3770

September 22, 20262026 Ohio 3648

September 16, 20262026 Ohio 3555

OhioSheetz, Inc. v. Centerville

September 15, 20262026 Ohio 3531

The Ohio Supreme Court answered a certified question of state law, holding that because Ohio law bars claims for damages and declaratory relief in an R.C. Ch. 2506 administrative appeal, the doctrine of res judicata does not preclude pursuing those claims in a later Section 1983 action.

OhioCarlton v. Palmer

September 10, 20262026 Ohio 3486

September 3, 20262026 Ohio 3439

OhioJohnson v. Stuff

September 2, 20262026 Ohio 3379

The court affirmed dismissal of Johnson’s habeas petition because his asserted pretrial and arraignment errors challenged only the exercise of jurisdiction, not the trial court’s jurisdiction itself, and therefore were cognizable, if at all, through direct appeal.

August 27, 20262026 Ohio 3308

The Supreme Court of Ohio held that subsequent amendments to two statutes first enacted in an allegedly unconstitutional budget bill cured any purported violation of the Ohio Constitution's one-subject rule, because the amendments repealed the contested provisions and enacted new provisions that must be judged…

OhioState v. Fontanez

August 26, 20262026 Ohio 3281

August 25, 20262026 Ohio 3270

August 21, 20262026 Ohio 3204

August 21, 20262026 Ohio 3208

OhioState v. Cobb

August 20, 20262026 Ohio 3188
