A memorandum decision is a short court ruling that announces the outcome of a case with little or no written explanation of the court’s reasoning. It fully resolves the dispute between the parties and is just as enforceable as a lengthy published opinion, but it typically carries no precedential weight, meaning other courts are not required to follow it in later cases. More than 87 percent of federal appeals are resolved this way.
What the Document Actually Looks Like
A memorandum decision communicates the court’s conclusion with minimal explanation. The court might list a few case citations, summarize the key facts in a sentence or two, and announce the result. That is often the entire document. Courts use this format when the legal issues are straightforward and the outcome follows clearly from existing law, so there is nothing new to explain to the legal community.
The Fourth Circuit describes its own unpublished opinions bluntly, noting they “may not recite all of the facts or background of the case and may simply adopt the reasoning of the lower court.”1U.S. Court of Appeals for the Fourth Circuit. Appellate Procedure Guide – Opinion and Judgment If you were expecting a detailed walk-through of the court’s thinking, you may not get one.
What It Means for Your Case
A memorandum decision fully resolves the dispute between the parties. If the court rules against you in a memorandum decision, that ruling is just as enforceable as one delivered in a 50-page published opinion. You must comply with it. The “non-precedential” label does not make the outcome optional, and it does not signal that the court viewed your case as unimportant.
What the label does affect is the ruling’s reach beyond your case. A non-precedential decision does not bind other courts. A judge facing a similar question in a later case is not required to follow the memorandum decision’s reasoning. The Tenth Circuit’s local rules say unpublished decisions “are not precedential, but may be cited for their persuasive value.” The Federal Circuit goes further, noting it “will not give one of its own nonprecedential dispositions the effect of binding precedent.”2Federal Judicial Center.

So the practical split is this: the ruling binds you and the other party completely, but it usually doesn’t shape the law for anyone else.
Why Courts Issue Them Instead of Full Opinions
Each federal circuit maintains its own criteria for deciding whether an opinion deserves publication, and the standards are similar across circuits. Published opinions are generally reserved for cases that establish new law, clarify or change an existing rule, resolve a conflict within the circuit, criticize current law, or address an issue of ongoing public importance.1U.S. Court of Appeals for the Fourth Circuit. Appellate Procedure Guide – Opinion and Judgment
Most cases clear none of those bars. They simply apply settled law to a particular set of facts, and the court sees no reason to add another published opinion restating what other opinions already say. The memorandum format lets the court resolve the case efficiently and move on.
Other Names You Might See
The terminology varies. Some courts call them “memorandum opinions,” others “memorandum decisions” or “memorandum orders.” You may also see “unpublished opinion,” “non-precedential disposition,” or “not for publication” stamped on the document. These labels all describe roughly the same thing: a ruling the court chose not to develop into a full, published opinion.
Not the Same as a Per Curiam Opinion
A memorandum decision should not be confused with a per curiam opinion. Per curiam opinions are also typically short and unsigned, but they are issued “by the court” as an institution and carry full precedential weight. A per curiam opinion says the court agrees unanimously and the law is clear. A memorandum decision says the court resolved your case but chose not to add to the published body of law.
Can You Cite a Memorandum Decision Later?
In federal court, yes, within limits. Federal Rule of Appellate Procedure 32.1, effective January 1, 2007, prohibits any federal court of appeals from banning the citation of unpublished opinions issued on or after that date. The rule states that “a court may not prohibit or restrict the citation of federal judicial opinions, orders, judgments, or other written dispositions” designated as unpublished or non-precedential, as long as they were issued on or after the rule’s effective date.3Legal Information Institute. Federal Rules of Appellate Procedure Rule 32.1 – Citing Judicial Dispositions
The rule stops there. It deliberately leaves open how much weight a court should give an unpublished opinion. The committee notes state that it “says nothing about what effect a court must give to one of its unpublished opinions or to the unpublished opinions of another court.”4Legal Information Institute. Federal Rules of Appellate Procedure Rule 32.1 – Citing Judicial Dispositions – Section: Committee Notes on Rules 2006 You can cite it; the court is free to give it little or no weight.
Even in jurisdictions with the strictest limits on citation, every federal circuit allows unpublished opinions to be cited in related cases for three recurring purposes:
- Res judicata, to prove the same claim between the same parties was already decided.
- Collateral estoppel, to show a specific factual or legal issue was already resolved.
- Law of the case, to establish that a court already ruled on an issue within the same ongoing litigation.
Some circuits go further and allow citation for persuasive value when no published opinion addresses the issue as well. The Eighth Circuit, for example, permits citation of unpublished opinions if they have “persuasive value on a material issue and no published opinion of this or another court would serve as well.”2Federal Judicial Center. Citing Unpublished Federal Appellate Opinions Issued Before 2007
State courts set their own rules on citing unpublished decisions, and the range is wide. Before relying on a memorandum decision in any court, check that court’s local rules. The restriction that catches people off guard is the state-level one they never looked up.
Where You’ll Typically See One
Pretrial Motions
Trial courts frequently use memorandum decisions when ruling on routine pretrial motions. A motion for summary judgment asks the court to decide the case without a trial because the facts are undisputed and the law clearly favors one side.5Legal Information Institute. Federal Rules of Civil Procedure Rule 56 – Summary Judgment If the court agrees, it can resolve the motion with a brief memorandum decision rather than a full written opinion. The same applies to motions to dismiss and many discovery disputes. Federal magistrate judges, who handle a large share of pretrial work, routinely issue short written orders on non-dispositive matters under Federal Rule of Civil Procedure 72.6LII / Legal Information Institute. Rule 72 – Magistrate Judges Pretrial Order
Appellate Affirmances
Appellate courts are the heaviest users of memorandum decisions. When a panel reviews a lower court’s ruling and finds no reversible error, the straightforward outcome is affirmance. If the appeal raises no novel legal question and the lower court applied the right law to the right facts, a memorandum opinion affirming the judgment lets the court dispose of the appeal without generating a published opinion that would simply restate existing law.
Tax Court Memorandum Opinions
The United States Tax Court has its own version of this distinction. After hearing a case, the court issues either a “Division” opinion (cited as “T.C.”) or a “Memorandum” opinion (cited as “T.C. Memo”). Federal statute directs the Tax Court to include in its report on any proceeding “its findings of fact or opinion or memorandum opinion.”7Office of the Law Revision Counsel. 26 USC 7459 – Reports and Decisions Division opinions are treated as binding precedent within the Tax Court. Memorandum opinions are technically non-precedential and are intended for cases where the court is applying well-established tax law to a particular taxpayer’s facts.
In practice the line is blurrier than the labels suggest. Roughly 90 percent of all Tax Court opinions are memo opinions, and the court itself routinely cites them. If you’re involved in Tax Court litigation, don’t assume a memo opinion is unimportant just because it carries the “T.C. Memo” label.
Immigration Court and the Board of Immigration Appeals
The Board of Immigration Appeals leans heavily on single-member adjudication. Under federal regulations, all cases are assigned to a single Appellate Immigration Judge unless the case meets specific criteria for three-member panel review, such as settling inconsistencies between immigration judges, establishing precedent, or resolving a case of major national importance.8eCFR. 8 CFR 1003.1 – Organization, Jurisdiction, and Powers of the Board of Immigration Appeals
The Board can go further with a procedure called “affirmance without opinion,” where a single Board member affirms the immigration judge’s decision with no written explanation at all. This is permitted when the result below was correct, any errors were harmless, and the legal issues on appeal are controlled by existing precedent without a novel factual situation.8eCFR. 8 CFR 1003.1 – Organization, Jurisdiction, and Powers of the Board of Immigration Appeals For someone whose asylum case or deportation appeal ends this way, the result can feel jarring. The system is designed for efficiency, not explanation.
What To Do If You Receive One
Your rights as a party are the same whether the ruling came as a memorandum decision or a published opinion. You can appeal, seek rehearing, or petition for review on the same timeline and under the same standards. The non-precedential label affects the ruling’s influence on later cases, not your ability to challenge the outcome in your own.
If you believe your case should be published, many federal circuits let you request it. The Fourth Circuit permits counsel to “move for publication of an unpublished opinion, citing reasons,” and if the motion is granted, the opinion is published “without change in result.”1U.S. Court of Appeals for the Fourth Circuit. Appellate Procedure Guide – Opinion and Judgment Other circuits have similar procedures with their own deadlines; the D.C. Circuit, for example, requires the motion within 30 days after judgment. These requests are rarely granted, but the mechanism exists.
If the decision went against you and you believe the court erred, focus on the substance of the ruling. Your appeal or rehearing petition should address the legal or factual errors in the decision itself, not the brevity of the opinion.
