The short answer

Missouri case law search means finding the Supreme Court of Missouri and Missouri Court of Appeals decisions that control your issue. Two things make Missouri unusual. First, Missouri puts stare decisis in its constitution rather than leaving it to common law: article V, section 2 states that the Supreme Court's "decisions shall be controlling in all other courts." Second, a Missouri appellate panel can affirm by memorandum decision and attach a written statement explaining exactly why, and that statement, under Rule 84.16(b), "shall not be reported, and shall not be cited or otherwise used in any case before any court." The reasoning exists on paper, the parties read it, and it is legally invisible to everyone else.

Art. V, sec. 2

Missouri writes stare decisis into its constitution: Supreme Court decisions "shall be controlling in all other courts"

3 districts

The Court of Appeals sits in St. Louis, Kansas City, and Springfield, and no district binds another

Rule 84.16(b)

A statement explaining a memorandum affirmance may not be reported, cited, or otherwise used in any court

1 dissent

A single judge certifying a conflict forces transfer to the Supreme Court under article V, section 10

Side by side

The Missouri court structure and what actually binds your court

Missouri runs one intermediate appellate court divided into three districts, and which district hears your appeal depends on where the case was tried. Above them sit seven Supreme Court judges in Jefferson City whose decisions are constitutionally controlling everywhere in the state. The gap most researchers miss is horizontal: a published Eastern District opinion is not binding on the Western District, and the constitution contains its own machinery for resolving the conflicts that follow.

Court What it decides How it is cited Precedential weight
Supreme Court of Missouri Exclusive appellate jurisdiction in five constitutional categories, plus cases taken on transfer, decided by seven judges S.W.3d, with a "(Mo. banc)" parenthetical when the full court sits Constitutionally controlling in every other Missouri court under article V, section 2
Court of Appeals, Eastern District, published opinion Appeals from the circuit courts in its territory, heard by three-judge panels drawn from fourteen judges in St. Louis S.W.3d, with a "(Mo. App. E.D.)" parenthetical Binding on the circuit courts within the district, persuasive in the other two districts
Court of Appeals, Western District, published opinion The same appeals from its own territory, heard by panels drawn from eleven judges in Kansas City S.W.3d, with a "(Mo. App. W.D.)" parenthetical Binding on the circuit courts within the district, persuasive in the other two districts
Court of Appeals, Southern District, published opinion The same appeals from its own territory, heard by panels drawn from seven judges in Springfield S.W.3d, with a "(Mo. App. S.D.)" parenthetical Binding on the circuit courts within the district, persuasive in the other two districts
Memorandum decision or written order under Rule 84.16(b) A unanimous affirmance the panel believes would have no precedential value Generally not cited at all None, and any attached explanatory statement may not be cited or otherwise used in any court
A Court of Appeals opinion in a case later transferred Any appeal the Supreme Court takes by certification, transfer, or certiorari Cite the Supreme Court opinion instead Superseded, because the Supreme Court decides the cause "the same as on original appeal"
Eighth Circuit and the Missouri federal district courts Federal questions and diversity cases applying Missouri law F.4th, F. Supp. 3d Persuasive only in state court on questions of Missouri law

How do I search Missouri case law?

Start with the district. Missouri has one Court of Appeals divided into Eastern, Western, and Southern districts, and the district that hears your appeal is set by where the case was tried, not by what it is about. That matters because the districts are coordinate courts. A published Eastern District opinion binds the circuit courts inside the Eastern District, but the Western District is free to read the same statute differently, and sometimes does. If you search "Missouri Court of Appeals" as though it spoke with one voice, you will find authority that reads as settled and is not settled in the courtroom you are standing in.

Then describe the issue as a full question rather than a string of keywords, with the statute, the parties, and the procedural posture in it. Missouri appellate opinions turn heavily on the standard of review, and the standard is usually stated in the first paragraphs rather than in the holding you are hunting for. A search that knows you are appealing a court-tried judgment rather than a jury verdict surfaces a different and much shorter list of cases than one that only knows your legal theory.

Finish by checking the disposition, not just the text. Missouri gives you two ways to be wrong about a case that reads perfectly well. It may have been affirmed by memorandum decision, in which case there is nothing citable no matter how sound the reasoning looks. Or the Supreme Court may have taken the case on transfer, in which case the Court of Appeals opinion in front of you has been superseded by a decision you have not read yet.

Missouri puts stare decisis in its constitution

Most states treat the binding force of their highest court as a matter of common law and judicial practice. Missouri wrote it down. Article V, section 2 of the Missouri Constitution provides, in full: "The supreme court shall be the highest court in the state. Its jurisdiction shall be coextensive with the state. Its decisions shall be controlling in all other courts. It shall be composed of seven judges, who shall hold their sessions in Jefferson City at times fixed by the court."

The practical consequence is the doctrine Missouri lawyers know as following the last controlling decision. A Missouri court confronted with a Supreme Court holding it thinks is wrong, or thinks has been undermined by later reasoning, does not get to work around it. The obligation is constitutional, and the remedy is to get the case to the Supreme Court so that court can reconsider its own decision. That is not a stylistic difference from other states. It changes what an intermediate court will do with a well-argued brief asking it to distinguish an inconvenient Supreme Court case.

It also changes how you should weigh what you find. In Missouri the age of a Supreme Court decision does very little on its own to weaken it. What weakens it is a later Supreme Court decision, which is precisely the thing a full-text keyword search is worst at surfacing, because the later case will rarely repeat the language you searched for. Our guide on <a href="/blog/how-to-check-if-a-case-is-still-good-law">checking whether a case is still good law</a> covers what treatment signals actually tell you here.

The reasoning you are allowed to read but not allowed to cite

Rule 84.16(a) requires that every appellate decision in Missouri "shall be reduced to writing and filed in the cause." Rule 84.16(b) then carves out an exception that has no close equivalent in most states. Where all the judges agree to affirm and believe an opinion would have no precedential value, the panel may dispose of the appeal by memorandum decision or written order. It may do so only when the court unanimously finds that at least one of five listed circumstances exists and is dispositive: that a judgment reviewable under Rule 84.13(d) is supported by substantial evidence and is not against the weight of the evidence, citing <em>Murphy v. Carron</em>, 536 S.W.2d 30 (Mo. banc 1976); that findings in a Rule 24.035 or Rule 29.15 proceeding are not clearly erroneous; that the evidence supporting a jury verdict is not insufficient; that an administrative order is supported by competent and substantial evidence on the whole record; or that no error of law appears.

Here is the part that surprises people. The panel may attach a written statement setting out the basis for its decision. The rule then says that statement "shall be unanimous, shall not constitute a formal opinion of the court, shall not be reported, and shall not be cited or otherwise used in any case before any court." So the losing party receives a written explanation of exactly why they lost, signed off by every judge on the panel, and no one may ever put it in a brief. Not the parties, not a later litigant, not a judge.

For a researcher this means Missouri has a large body of appellate work that is invisible to precedent even though it is not secret. If you find a Missouri disposition that affirms without a reported opinion, there is no citable authority there, and no amount of quality in the reasoning changes that. Rule 84.16 was adopted June 13, 1979, effective January 1, 1980, and was last amended May 26, 2000, effective January 1, 2001. It is worth reading once in full if you practice in Missouri, because it also tells you what a memorandum decision must contain, which is how you recognize one on sight.

How a single dissenting judge can move your case to the Supreme Court

Because Missouri districts do not bind each other, the constitution builds in its own conflict resolution. Article V, section 10 makes transfer mandatory in one situation: cases pending in the Court of Appeals "shall be transferred to the supreme court when any participating judge dissents from the majority opinion and certifies that he deems said opinion to be contrary to any previous decision of the supreme court or of the court of appeals, or any district of the court of appeals."

Read that carefully, because it is doing more work than it looks like. One judge, in dissent, can certify a conflict and the case goes up. And the conflict does not have to be with the Supreme Court. It can be with a previous decision of any district of the Court of Appeals, including a district that had no involvement in the case. That provision only makes sense in a system where districts genuinely can and do disagree, which is the clearest confirmation available that a sister district opinion is persuasive rather than binding.

The same section provides two discretionary routes. A majority of the participating district may order transfer after opinion, and the Supreme Court may order transfer before or after opinion "because of the general interest or importance of a question involved in the case, or for the purpose of reexamining the existing law." However the case arrives, the effect on your research is the same, and it is set out in the section itself: the Supreme Court "may finally determine all causes coming to it from the court of appeals, whether by certification, transfer or certiorari, the same as on original appeal." The Court of Appeals opinion stops being the answer.

Reading and citing a Missouri decision correctly

Missouri appellate decisions are published in the South Western Reporter, so a modern Missouri case cites to S.W.3d. The court parenthetical is where Missouri carries information other states put elsewhere. A Supreme Court case decided by the full court carries "(Mo. banc)" with the year, and that banc notation is worth noticing rather than copying, because it tells you the whole court spoke. Court of Appeals decisions identify the district: "(Mo. App. E.D.)", "(Mo. App. W.D.)", or "(Mo. App. S.D.)". Since the district determines who is actually bound, dropping it makes the citation much less useful to the judge reading your brief. Our walkthrough on <a href="/blog/how-to-read-a-legal-citation">how to read a legal citation</a> covers the general structure.

The judges behind those parentheticals are selected under a system Missouri invented. Voters adopted the Missouri Nonpartisan Court Plan by initiative petition in November 1940, after a run of contentious judicial elections, and it became the model that many other states copied as merit selection. A nonpartisan commission screens applicants and sends the governor a short list, the governor appoints from it, and the judge later stands in a retention election. It governs the Supreme Court, the entire Court of Appeals, and six circuit courts: Jackson, Clay, and Platte counties in the Kansas City area, the City of St. Louis, St. Louis County, and Greene County around Springfield. Appellate judges serve twelve year terms and face mandatory retirement at seventy. Elsewhere in Missouri, circuit judges are still elected in contested partisan races, which is a difference worth knowing when you are reading trial court history in an appellate record.

What Missouri research usually costs a small firm in time

The recurring expense in Missouri is not finding cases. It is confirming that what you found still counts. Three separate questions have to be answered for every authority: which district decided it and whether that district governs your circuit, whether the disposition was a full opinion or a memorandum affirmance, and whether the Supreme Court later took the case on transfer. None of those is answered by the text of the opinion, and all three are the kind of check that gets skipped at eleven at night the day before a brief is due.

That is the specific job Casesearch is built for. Ask the question in plain English, get the controlling Missouri decisions with the holding stated in ordinary language, the citation formatted with the district parenthetical, and a signal for whether the case has been treated badly since. You still read the opinion and you still exercise judgment, because this is a research tool rather than legal advice, but you spend that judgment on the argument instead of on reconstructing procedural history by hand.

Frequently asked

Questions buyers ask about missouri supreme court opinions

How do I search Missouri case law?

Start with the district, since the Eastern, Western, and Southern districts of the Court of Appeals are coordinate courts and only your own district binds your circuit court. Describe the issue as a full question including the standard of review, then confirm the disposition was a full opinion rather than a memorandum affirmance and that the Supreme Court did not later take the case on transfer.

Are Missouri Court of Appeals decisions binding on other districts?

No. A published opinion binds the circuit courts within its own district and is persuasive authority in the other two. Article V, section 10 of the Missouri Constitution confirms this by making transfer mandatory when a dissenting judge certifies that the majority opinion conflicts with a previous decision of any district of the Court of Appeals.

Can you cite a memorandum decision in Missouri?

No. Under Rule 84.16(b) a panel may affirm by memorandum decision or written order when all judges agree the case would have no precedential value. Any written statement explaining the basis for that decision "shall not be reported, and shall not be cited or otherwise used in any case before any court," so there is no citable authority even though the reasoning was written down.

What happens to a Court of Appeals opinion when the Supreme Court grants transfer?

It stops being the operative decision. Article V, section 10 provides that the Supreme Court "may finally determine all causes coming to it from the court of appeals, whether by certification, transfer or certiorari, the same as on original appeal." You cite the Supreme Court opinion, and checking for transfer is a required step before relying on any Missouri appellate case.

How many judges are on the Supreme Court of Missouri?

Seven. Article V, section 2 of the Missouri Constitution states that the court "shall be composed of seven judges, who shall hold their sessions in Jefferson City at times fixed by the court." The same section makes the court's jurisdiction coextensive with the state and its decisions controlling in all other courts.

How do I cite a Missouri case?

Cite to S.W.3d. Add "(Mo. banc)" and the year for a Supreme Court decision by the full court, or the district for a Court of Appeals decision: "(Mo. App. E.D.)", "(Mo. App. W.D.)", or "(Mo. App. S.D.)". The district parenthetical matters in Missouri because it tells the reader which courts are actually bound by the decision.

What is the Missouri Nonpartisan Court Plan?

It is the merit selection system Missouri voters adopted by initiative petition in November 1940, and the model many states later copied. A nonpartisan commission screens applicants, the governor appoints from its short list, and the judge later stands in a retention election. It covers the Supreme Court, the Court of Appeals, and six circuit courts including Jackson County and the City of St. Louis.

Where does each district of the Missouri Court of Appeals sit?

The Eastern District sits in St. Louis with fourteen judges, the Western District in Kansas City with eleven, and the Southern District in Springfield with seven. All three hear appeals from the circuit courts in their own territory in three-judge panels, and appellate judges serve twelve year terms with mandatory retirement at seventy.
