The short answer
Massachusetts case law search means finding the decisions of the Supreme Judicial Court and the Massachusetts Appeals Court that control your issue. Massachusetts is the clean case that many states are not: there is one intermediate appellate court, it sits in rotating three judge panels rather than geographic divisions, and a published Appeals Court decision therefore binds every trial court in the Commonwealth. The complication is not geography, it is publication status. The Appeals Court disposes of a large share of its docket by unpublished summary decision, and those decisions may be cited for persuasive value only if they issued on or after February 26, 2008.

Side by side
The Massachusetts court structure and what actually binds your court
Massachusetts keeps a single statewide Appeals Court, so unlike Washington or Florida you never have to ask which appellate district your case sits in. What you do have to ask, on every result, is whether the decision was published or issued as a summary disposition.
| Court | What it decides | How it is cited | Precedential weight |
|---|---|---|---|
| Supreme Judicial Court | Further appellate review, direct appellate review, constitutional questions | Mass., parallel N.E.3d | Binding on every court in Massachusetts |
| Appeals Court (published) | Most appeals from the seven Trial Court departments and three state agencies | Mass. App. Ct., parallel N.E.3d | Binding on every trial court in the Commonwealth |
| Appeals Court (Rule 23.0, formerly 1:28) | The same appeals, resolved by unpublished summary decision | Case name, the Mass. App. Ct. page noting issuance, and the rule | No precedential value, citable for persuasive value only if issued on or after February 26, 2008 |
| Appellate Division of the District Court | Appeals from civil matters in the District Court departments | Mass. App. Div. | Persuasive, and subject to Appeals Court review |
| Superior Court | General jurisdiction civil and felony trials | Not published as precedent | No precedential value |
| District, Boston Municipal, Probate and Family, Housing, Land, Juvenile | The six other Trial Court departments, by subject matter and territory | Not published as precedent | No precedential value |
| First Circuit and D. Mass. | Federal questions and diversity cases applying Massachusetts law | F.4th, F. Supp. 3d | Persuasive only in state court on questions of Massachusetts law |

How do I search Massachusetts case law?
Describe the issue as a full question rather than a string of keywords, name the Trial Court department the case sits in, and then read every result with one filter that Massachusetts makes unavoidable: published opinion or summary decision. Those are the two products of the same court, they look nearly identical in a free full text search, and only one of them is authority you can build an argument on.
After that the ordinary checks apply, in a specific order. Look first for a Supreme Judicial Court holding, because it settles the question statewide. If there is none, a published Appeals Court decision is binding on your trial court no matter where in the Commonwealth you are sitting. Only then reach for summary decisions, Appellate Division opinions, or Superior Court decisions, all of which persuade rather than control. Finally, confirm the SJC has not granted further appellate review or decided the issue since your case issued, which is the most common way a Massachusetts authority quietly goes stale.
Ask in a full sentence
Include the statute or G.L. chapter, the parties, and the procedural posture so the search has real facts to match.
Check publication status first
A Rule 23.0 summary decision is not precedent, however on point it looks.
Skip the district question
There are no appellate divisions in Massachusetts, so a published Appeals Court decision binds statewide.
Look for a grant of FAR
An SJC grant of further appellate review can unsettle the Appeals Court decision you are relying on.
Are Massachusetts Appeals Court decisions binding on trial courts?
Yes, when they are published. The Massachusetts Appeals Court was created in 1972 as a court of general appellate jurisdiction, and it is the only intermediate appellate court in the Commonwealth. It consists of a chief justice and 24 associate justices who hear cases in three judge panels that rotate, so that over time every justice sits with every other justice. Because there are no geographic divisions, there is no such thing as an Appeals Court decision that controls in Springfield but merely persuades in Boston. A published decision is binding on every Trial Court department in Massachusetts until the SJC says otherwise.
That is genuinely simpler than most of the large states. Washington splits its intermediate court into three co-equal divisions that do not bind each other. Florida runs six District Courts of Appeal. Illinois has five appellate districts with their own body of law. In Massachusetts the only hierarchy question worth asking is whether the SJC has spoken, and the SJC can reach a case two ways: it can take an appeal before the Appeals Court hears it through direct appellate review under Mass. R. App. P. 11, or it can take it afterward through further appellate review under Rule 27.1, on an application filed within 21 days and granted for substantial reasons affecting the public interest or the interests of justice.
One category sits outside the ordinary precedent ladder entirely. Under Part II, c. 3, art. 2 of the Massachusetts Constitution of 1780, either branch of the Legislature, the Governor, or the Council may require the opinions of the justices of the Supreme Judicial Court upon important questions of law and upon solemn occasions. Those Opinions of the Justices are advisory. They are given by the justices individually, outside any decided case, so they are not binding precedent even though courts and counsel quote them for their reasoning. If you find one on your issue, treat it as informed commentary from seven very relevant people rather than as a holding.
One court, no divisions
A published Appeals Court decision binds every trial court in the Commonwealth.
Three judge rotating panels
Panels rotate rather than sitting as fixed geographic benches.
Direct appellate review
Mass. R. App. P. 11 lets the SJC take an appeal before the Appeals Court decides it.
Further appellate review
Rule 27.1, filed within 21 days of the Appeals Court decision.
Can you cite an unpublished Rule 1:28 decision in Massachusetts?
Yes, for persuasive value only, and only if the decision issued on or after February 26, 2008. This is the single rule that catches out researchers new to Massachusetts practice, and it has two traps in it. The first is the date. No summary decision issued before February 26, 2008 may be cited at all, so a perfectly on point 2004 decision sitting in your search results is simply unusable. The change followed the Appeals Court decision in Chace v. Curran, 71 Mass. App. Ct. 258 (2008).
The second trap is the name. These decisions were issued under Appeals Court Rule 1:28 for decades, and practitioners still call them 1:28 decisions in conversation and in memos. The rule was renumbered effective July 1, 2020: decisions released before that date are cited as Rule 1:28 decisions, and decisions released on or after it are cited as Rule 23.0 decisions. If you search only for one label you will miss half the body of work, and if you cite a 2023 decision as a Rule 1:28 decision you have got the rule wrong on the face of your brief.
The mechanics of citing one are specific. You give the case name, a citation to the page of the Massachusetts Appeals Court Reports where issuance of the decision is noted, and a notation that the decision issued pursuant to the rule, and you attach a copy of the decision to your filing. None of that converts it into precedent. A summary decision has no precedential value, a court is free to disregard it, and if the only support for your proposition is a summary decision, that is a signal to keep researching rather than a signal to file. Our guide on when you can cite an unpublished opinion covers how the federal courts and other states handle the same question.
February 26, 2008
Nothing issued before this date may be cited, regardless of how on point it is.
July 1, 2020
The renumbering date: Rule 1:28 before, Rule 23.0 on and after.
Attach a copy
A summary decision must be appended to the brief or motion that cites it.
Persuasive, never binding
Summary decisions have no precedential value in any Massachusetts court.
How do I cite a Massachusetts case?
Massachusetts cites to its own official reports with a parallel North Eastern Reporter cite. Supreme Judicial Court decisions appear in Massachusetts Reports, abbreviated Mass., and Appeals Court decisions appear in Massachusetts Appeals Court Reports, abbreviated Mass. App. Ct. Both also appear in the North Eastern Reporter, currently N.E.3d. Briefs filed in Massachusetts courts follow the Supreme Judicial Court Style Manual maintained by the Reporter of Decisions; briefs filed elsewhere follow Table 1 of the Bluebook.
Massachusetts has not adopted a public domain or medium neutral citation format, unlike Illinois or Ohio. That matters more than it sounds, because it means a recent decision has no permanent citation until it reaches the official reports. A slip opinion is cited by case name, docket number, and date until the volume and page exist. It also means there is no neutral way to pinpoint a paragraph, so pinpoint cites are to printed pages. For older Massachusetts material there is one more wrinkle worth knowing: volumes of the official reports from 1822 to 1867 were named for the individual Reporter of Decisions rather than numbered, which is why nineteenth century Massachusetts citations carry abbreviations like Pick. for Pickering or Cush. for Cushing. If the parts of a citation are unfamiliar, our breakdown of how to read a legal citation walks through reporters, pinpoints, and parentheticals.
Supreme Judicial Court
Mass., with a parallel N.E.3d cite.
Appeals Court
Mass. App. Ct., with a parallel N.E.3d cite.
Summary decisions
Case name, the Mass. App. Ct. page noting issuance, and the rule, plus an attached copy.
No neutral citation
Cite an unreported case by docket number and date until it reaches the official reports.
Where can I find Massachusetts case law online?
The official opinions are free. The Massachusetts court system posts SJC and Appeals Court slip opinions on the day they are released, and the Social Law Library and the Trial Court Law Libraries provide public access to Massachusetts materials. Google Scholar and CourtListener carry the same opinions with better full text search than the official sites offer. What none of them give you is a citator, a plain-language holding, or a reliable warning that the decision you are reading is a summary disposition with no precedential value.
That last gap is where Massachusetts research goes wrong in practice. A free search engine will hand you a summary decision and a published opinion side by side with almost nothing to distinguish them, and it will not tell you that the SJC granted further appellate review last spring. The enterprise tools solve it with editorial headnotes and the KeyCite and Shepard's citators, at a per seat cost a two lawyer firm in Worcester struggles to justify. A self-serve research tool that returns the cited holding, names the deciding court, and flags subsequent treatment covers the everyday work at a fraction of that. We lay out the whole category in the legal research software guide, and the real price ranges in the legal research software pricing breakdown.
Frequently asked
Questions buyers ask about massachusetts case law search
How do I search Massachusetts case law?
Describe your issue as a full question and search decisions of the Supreme Judicial Court and the Massachusetts Appeals Court. Check the publication status of every result, because the Appeals Court resolves much of its docket by unpublished summary decision. Then confirm the SJC has not granted further appellate review or decided the question since your case issued.
Are Massachusetts Appeals Court decisions binding on trial courts?
Yes, when published. Massachusetts has a single statewide intermediate appellate court with no geographic divisions, so a published Appeals Court decision binds every Trial Court department in the Commonwealth until the Supreme Judicial Court holds otherwise. Unpublished summary decisions issued under Rule 23.0 have no precedential value anywhere.
Can you cite an unpublished Rule 1:28 decision in Massachusetts?
Only for persuasive value, and only if it issued on or after February 26, 2008. You must cite the case name, the page of the Massachusetts Appeals Court Reports noting issuance, and the rule, and attach a copy to your filing. Decisions released on or after July 1, 2020 are cited as Rule 23.0 rather than Rule 1:28.
What is the difference between Rule 1:28 and Rule 23.0?
They are the same kind of unpublished Appeals Court summary decision under two names. The rule was renumbered effective July 1, 2020, so decisions released before that date are cited as Rule 1:28 decisions and decisions released on or after it are cited as Rule 23.0 decisions. Searching for only one label will miss half the available decisions.
How do I cite a Massachusetts case?
Cite the official reports with a parallel North Eastern Reporter cite: Mass. for Supreme Judicial Court decisions and Mass. App. Ct. for Appeals Court decisions, both with N.E.3d. Follow the SJC Style Manual for filings in Massachusetts courts. Massachusetts has no public domain citation format, so unreported cases are cited by docket number and date.
What is the highest court in Massachusetts?
The Supreme Judicial Court, made up of a chief justice and six associate justices. It is the oldest appellate court in continuous existence in the Western Hemisphere, its decisions bind every court in the Commonwealth, and it reaches cases either through direct appellate review before the Appeals Court rules or through further appellate review afterward.
How many judges are on the Massachusetts Appeals Court?
Twenty five: a chief justice and 24 associate justices. The court was created in 1972 and hears cases in rotating three judge panels rather than fixed geographic divisions, which is why a single published Appeals Court decision is binding statewide rather than in one region.
