The short answer
Ohio case law search means finding opinions of the Supreme Court of Ohio and the twelve district courts of appeals that control your issue. Since May 1, 2002, every Ohio opinion carries a public-domain WebCite in the form State v. Jones, 2003-Ohio-5994, and pinpoints are cited by paragraph number rather than page. The Supreme Court website has been the official Ohio Reports for appellate opinions since July 1, 2012, so the print Ohio Appellate Reports no longer exists, though many opinions also appear in the North Eastern Reporter (N.E.3d). A court of appeals opinion binds trial courts only within its own district.

The Ohio court structure and what binds your court
Ohio is unusual in that its own website is the official reporter and each opinion carries a WebCite, so knowing the district matters as much as the reporter volume.
| Court | What it decides | How it is cited | Precedential weight |
|---|---|---|---|
| Supreme Court of Ohio | Discretionary review, constitutional questions, death penalty, certified conflicts | WebCite (2024-Ohio-1234), also N.E.3d | Binding on every Ohio court |
| District courts of appeals (12) | Appeals as of right from common pleas, municipal and county courts | WebCite with district in parens, e.g. (10th Dist.) | Binds trial courts only within that district |
| Courts of common pleas | General civil and felony trials, domestic, probate, juvenile divisions | Not published as precedent | No precedential value |
| Municipal and county courts | Misdemeanors, small civil claims, traffic | Not published as precedent | No precedential value |
| Sixth Circuit and federal district courts | Federal questions and diversity cases applying Ohio law | F.4th, F.Supp.3d | Persuasive only in state court on Ohio law |

How do I search Ohio case law?
Describe the issue and the county, not just a keyword. An Ohio question usually turns on which of the twelve appellate districts your trial court sits in, because a published Eighth District opinion out of Cuyahoga County binds a Cuyahoga judge but only persuades a judge in the Tenth District in Columbus. Type the full question, including the county or district and the procedural posture, and let the search return the opinions from the court that actually controls.
Then check whether the districts agree. Ohio has no rule that one district binds another, so the twelve districts routinely split on the same issue. When they do, the losing side can ask the court of appeals to certify a conflict, and the Supreme Court of Ohio resolves it for the whole state. A research answer that ignores a certified-conflict case, or a pending certification, can be out of date the week you file it.
Name the district
Identify which of the twelve districts your trial court falls in before you weigh any court of appeals opinion.
Describe the issue in a sentence
Include the statute, the parties, and the procedural stage so the search has real facts to match.
Watch for district conflicts
When districts disagree, a Supreme Court certified-conflict decision may already control statewide.
Read the paragraphs you cite
Ohio pinpoints by paragraph number, so note the exact paragraphs you will rely on.
What is Ohio's WebCite and how do I cite an Ohio case?
Ohio assigns every appellate opinion a public-domain citation the moment it is posted, called the WebCite. It reads State v. Jones, 2003-Ohio-5994: the case name, the year, the word Ohio, and a sequential number for that year. Court of appeals opinions add the district in a parenthetical, for example State v. Jones, 2003-Ohio-5994, paragraph 6 (10th Dist.). Cases decided after May 1, 2002 must cite the WebCite, and to the official reporter cite if one exists.
This is why Ohio pinpoints look different from other states. There are no reporter page numbers in a WebCite, so the court numbers its own paragraphs and you cite to the paragraph. If the opinion also appears in the North Eastern Reporter you can add the N.E.3d parallel cite, but the Supreme Court of Ohio Writing Manual now treats the WebCite as the preferred and, for recent cases, the only required citation.
WebCite
Year-Ohio-Number, assigned when the opinion is posted to the court website.
District parenthetical
Court of appeals cites add the district, such as (8th Dist.) or (10th Dist.).
Paragraph pinpoints
Cite the court's numbered paragraphs, not a reporter page.
Optional N.E.3d parallel
Add the North Eastern Reporter cite when the opinion appears there, but it is no longer required.
Are Ohio court of appeals decisions binding statewide?
No. A court of appeals opinion is controlling authority only for the trial courts inside its own district, and merely persuasive everywhere else in Ohio. That is the single most common Ohio research mistake: pulling a strong opinion from another district and treating it as binding when it is not. In 2012 Ohio abolished the old distinction between controlling and persuasive opinions within a district, so today every court of appeals opinion, whether or not it was selected for print, is citable and carries the same weight inside its district.
When two districts reach opposite results on the same question, the court that decided the later case can certify the conflict to the Supreme Court of Ohio under Article IV of the Ohio Constitution. Until the Supreme Court rules, a trial judge follows the opinions of the district the court sits in. After it rules, that decision binds every Ohio court. So the binding-authority question in Ohio has two layers: which district, and whether the Supreme Court has already resolved a split.
How do I check whether an Ohio case is still good law?
Run the treatment check against three risks. The opinion can be reversed or disapproved by the Supreme Court of Ohio, directly or through a certified-conflict ruling that adopts the other district's view. It can be superseded by a statutory amendment, which happens often in Ohio criminal sentencing and civil procedure. Or a later case in the same district can distinguish or limit it without any higher court touching it.
Because Ohio districts diverge, a treatment check also has to tell you whether a conflicting line exists in another district, even when nothing has technically overruled your case. A case that is perfectly good law in the Sixth District may be directly contradicted by the Second District, and if your matter could move venue or reach the Supreme Court, that conflict is part of the answer. Read the current statute too whenever the holding turns on code language.
Where can I find Ohio case law online?
The official opinions are free. The Supreme Court of Ohio website posts every Supreme Court and court of appeals opinion with its WebCite, usually the day it is released, and keeps a searchable archive back to 1992. CourtListener and Google Scholar carry the same opinions with stronger full-text search. What the free sources do not give you is a citator, a plain-language holding, or any signal about a district conflict, which is exactly where Ohio research gets dangerous.
The paid tier buys editorial depth and a treatment system. Westlaw and Lexis carry headnotes and the KeyCite and Shepard's citators, which matter for complex Ohio appellate work. For the everyday job, finding the controlling opinions in your district, reading the holdings, and confirming they still stand, a self-serve research tool covers the work for a fraction of a seat. We compare the whole category in the legal research software guide.
Frequently asked
Questions buyers ask about ohio case law search
How do I search Ohio case law?
Describe your issue as a full question and name the county or appellate district your trial court sits in, then search opinions from the Supreme Court of Ohio and the twelve district courts of appeals. Because a court of appeals opinion binds only its own district, confirm which district controls and check for a Supreme Court certified-conflict ruling before you cite.
What is an Ohio WebCite?
The WebCite is Ohio's public-domain citation, assigned to every appellate opinion when it is posted to the court website. It reads like 2024-Ohio-1234: the year, the word Ohio, and a sequential number. Cases decided after May 1, 2002 must cite the WebCite, and pinpoints are given by paragraph number rather than a reporter page.
Are Ohio court of appeals decisions binding statewide?
No. An Ohio court of appeals opinion is binding only on the trial courts within its own appellate district and is persuasive elsewhere in the state. When two districts conflict, the later court can certify the conflict to the Supreme Court of Ohio, whose decision then binds every Ohio court.
What reporter are Ohio cases published in?
Since July 1, 2012, the Supreme Court of Ohio website is the official Ohio Reports for appellate opinions, so the print Ohio Appellate Reports is discontinued. Many Ohio opinions also appear in the North Eastern Reporter (N.E.3d), which you can add as a parallel cite, but the WebCite is the preferred citation.
How many appellate districts does Ohio have?
Ohio has twelve district courts of appeals, numbered First through Twelfth, each covering a group of counties and deciding cases in three-judge panels. A thirteenth appellate court, the Court of Claims, hears civil actions against the state. Each district's published opinions bind only the trial courts within that district.
