The short answer
Michigan case law search means finding opinions of the Michigan Supreme Court and the Michigan Court of Appeals that control your issue. Unlike many states, a published Court of Appeals opinion binds every trial court in Michigan statewide, not just one region, under MCR 7.215(C)(2). Michigan cites use parallel reporters, for example Phillips v Deihm, 213 Mich App 389, 401; 541 NW2d 566 (1995), with the official Michigan Reports or Michigan Appeals Reports first and the North Western Reporter second. Michigan has not adopted a public-domain citation, and its first-out rule (MCR 7.215(J)) forces a later Court of Appeals panel to follow the earliest conflicting published opinion.

The Michigan court structure and what binds your court
Michigan is unusual because a single statewide Court of Appeals means one published panel opinion controls trial courts everywhere in the state, so the date of the opinion can matter more than the county.
| Court | What it decides | How it is cited | Precedential weight |
|---|---|---|---|
| Michigan Supreme Court | Discretionary review by leave to appeal, constitutional questions, conflicts | Mich, parallel NW2d, e.g. 500 Mich 1 | Binding on every Michigan court |
| Michigan Court of Appeals (published) | Appeals as of right and by leave from the trial courts | Mich App, parallel NW2d, e.g. 213 Mich App 389 | Binding statewide on all trial courts and later panels |
| Michigan Court of Appeals (unpublished) | Same appeals, resolved without a precedential opinion | Slip or docket cite, marked unpublished | Not binding, citable only for persuasive value |
| Circuit, District, Probate, Municipal courts | General trials, limited civil and misdemeanor, estates and guardianship, plus four remaining municipal courts | Not published as precedent | No precedential value |
| Sixth Circuit and federal district courts | Federal questions and diversity cases applying Michigan law | F.4th, F.Supp.3d | Persuasive only in state court on Michigan law |

How do I search Michigan case law?
Describe the issue as a full question, not a keyword, and let the search return the controlling opinions. Because a published Michigan Court of Appeals opinion binds trial courts across the whole state, you are not hunting for a local appellate district the way you would in Ohio or Illinois. What you are hunting for is the earliest published opinion on your point that has not been reversed, because under the first-out rule that is the one a court must follow.
Then separate published from unpublished. Michigan issues far more unpublished Court of Appeals opinions than published ones, and the two carry completely different weight. A published opinion is binding statewide; an unpublished one is only persuasive, and you must explain why you are citing it and why no published authority covers the point. A search answer that treats an unpublished opinion as controlling authority is wrong on its face in Michigan.
Describe the issue in a sentence
Include the statute, the parties, and the procedural posture so the search has real facts to match.
Find the earliest published opinion
The first-out rule means the earliest controlling published panel opinion governs, so date order matters.
Check published versus unpublished
Only published Court of Appeals opinions bind; unpublished ones are persuasive only and need justification.
Confirm the Supreme Court has not moved it
A grant of leave to appeal or a later Supreme Court opinion can change what controls.
Are Michigan Court of Appeals decisions binding statewide?
Yes, when they are published. Under MCR 7.215(C)(2), a published Court of Appeals opinion has precedential effect under stare decisis and binds every trial court in Michigan, not merely the ones in the region the deciding judges were elected from. The Court of Appeals is a single statewide court of 24 judges who sit in rotating three-judge panels and hear cases from anywhere in the state, so there are no regional precedent zones the way there are in states with districted appellate courts.
That statewide effect is exactly why the first-out rule exists. With every published panel binding the whole state, two panels can reach opposite results on the same question, and something has to break the tie. Filing an application for leave to appeal to the Supreme Court does not suspend a published opinion's precedential force; it stays good law until the Supreme Court or a special conflict panel changes it.
What is Michigan's first-out rule?
The first-out rule, MCR 7.215(J)(1), requires a Court of Appeals panel to follow the rule of law established by a prior published Court of Appeals opinion issued on or after November 1, 1990, unless the Supreme Court or a special panel has reversed or modified it. A later panel cannot simply disagree and rule the other way. When two post-1990 published opinions conflict, a panel must follow the earlier one, which is where the "first-out" name comes from.
A panel that thinks the controlling opinion is wrong follows it anyway, then says in its published opinion that it would have reached a different result but for MCR 7.215(J)(1) and explains the conflict. That statement can trigger a poll of the judges and, if enough agree, a special conflict panel that resolves the split for all future panels. For a researcher, the practical lesson is that the newest opinion is not automatically the one that controls in Michigan; the earliest unreversed published opinion on the point usually is.
How do I cite a Michigan case?
Michigan uses parallel citations to the official reporter and the North Western Reporter, and it follows local conventions that differ from standard Bluebook form. A Court of Appeals cite looks like Phillips v Deihm, 213 Mich App 389, 401; 541 NW2d 566 (1995): the official Michigan Appeals Reports cite with a pinpoint page, a semicolon, then the North Western Reporter cite, then the year. Note there are no periods in Mich App or NW2d, and a semicolon separates the two reporters.
Supreme Court opinions cite to Michigan Reports (Mich) with the parallel NW2d. Michigan has not adopted a public-domain or medium-neutral citation, so for a case not yet in the printed reporters you cite the slip opinion by docket number and date. If you are unsure how the pieces fit, our guide to reading a legal citation breaks down reporters, pinpoints, and parentheticals.
Official reporter first
Michigan Reports (Mich) for the Supreme Court, Michigan Appeals Reports (Mich App) for the Court of Appeals.
North Western Reporter in parallel
Add the NW2d cite after a semicolon, e.g. 213 Mich App 389, 401; 541 NW2d 566 (1995).
Local style
No periods in Mich App or NW2d, and pinpoint pages follow a comma in the first cite.
No public-domain cite
For a case not yet reported, cite the slip opinion by docket number and date.
Where can I find Michigan case law online?
The official opinions are free. The Michigan Courts website posts Supreme Court and Court of Appeals opinions, marks each Court of Appeals opinion as published or unpublished, and keeps a searchable archive. Google Scholar and CourtListener 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 flag when a later published opinion or a first-out conflict has changed what controls.
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 Michigan appellate work. For the everyday job, finding the controlling published opinion, reading the holding, and confirming it still stands, a self-serve research tool covers the work for a fraction of an enterprise seat. We compare the whole category in the legal research software guide.
Frequently asked
Questions buyers ask about michigan case law search
How do I search Michigan case law?
Describe your issue as a full question and search opinions of the Michigan Supreme Court and the Michigan Court of Appeals. Because a published Court of Appeals opinion binds trial courts statewide, focus on finding the earliest unreversed published opinion on your point, and confirm whether it is published, because unpublished Michigan opinions are only persuasive.
Are Michigan Court of Appeals decisions binding statewide?
Yes. Under MCR 7.215(C)(2), a published Michigan Court of Appeals opinion is binding on every trial court in the state, because the Court of Appeals is a single statewide court rather than regional divisions. Unpublished opinions are not binding and may be cited only for persuasive value, with an explanation of why no published authority applies.
What is Michigan's first-out rule?
The first-out rule, MCR 7.215(J)(1), requires a Court of Appeals panel to follow a prior published opinion issued on or after November 1, 1990 that has not been reversed or modified. When two published opinions conflict, a panel must follow the earlier one. A panel that disagrees says so and can trigger a special conflict panel to resolve the split.
How do I cite a Michigan case?
Michigan uses parallel citations, for example Phillips v Deihm, 213 Mich App 389, 401; 541 NW2d 566 (1995). Cite the official Michigan Reports or Michigan Appeals Reports first, a semicolon, then the North Western Reporter, then the year. Michigan style uses no periods in Mich App or NW2d and has not adopted a public-domain citation.
Can you cite an unpublished Michigan opinion?
Yes, but only for persuasive value. Under MCR 7.215(C)(1), an unpublished Michigan Court of Appeals opinion is not binding precedent. A party who cites one must explain why it is being cited and how it is relevant, and should not cite it for a proposition for which published authority exists.
