Per Curiam

Definition

Per curiam (Latin: “by the court”) is an opinion delivered by an appellate court as a whole, rather than being attributed to a specific judge. Per curiam opinions are issued on behalf of the court collectively, reflecting the agreement of all participating judges. They are typically used for unanimous decisions on straightforward issues where the reasoning does not warrant individual attribution.

The per curiam form emphasizes that the decision is the court’s institutional judgment rather than any individual judge’s personal view. It signals that the decision was unanimous and that the court speaks with one voice. The lack of individual attribution reinforces the collective nature of appellate decision-making.

Characteristics of Per Curiam Opinions

Per curiam opinions are unsigned and do not identify the author. They represent the institutional voice of the court rather than the individual views of any judge. They are generally brief, addressing the issue directly without extensive doctrinal discussion. The reasoning is concise and focused on the dispositive points.

The U.S. Supreme Court issues per curiam opinions in cases deemed “noncontroversial” or where the correct resolution is clear, often without full briefing or oral argument. These summary dispositions resolve cases efficiently where the law is settled and the application straightforward. The Court may also issue per curiam opinions in more significant cases where it wishes to speak with one voice.

Per curiam opinions are typically unanimous, though not always. The term “per curiam” describes the form of the opinion, not the vote count. A per curiam opinion may have concurrences or dissents, though the opinion itself is unsigned.

When Per Curiam Opinions Are Used

Courts use per curiam opinions in several circumstances. Summary dispositions of appeals where the law is clear and the result obvious may be resolved by brief per curiam opinion. Unanimous decisions on settled law where extended reasoning would add nothing new often take per curiam form.

Cases involving obvious error that can be corrected without extended analysis are suitable for per curiam treatment. Procedural or jurisdictional rulings that do not involve the merits may be issued per curiam. Cases where the court is evenly divided are affirmed by an equally divided court, often announced per curiam.

Decisions where the court wishes to speak with one institutional voice may be issued per curiam to emphasize unanimity and downplay individual authorship. In politically sensitive cases, the per curiam form signals that the decision is the court’s collective judgment, not any individual justice’s personal view.

Per Curiam vs. Signed Opinions

Signed opinions are attributed to individual justices, who may write for the majority, concur separately, or dissent. Signed opinions allow individual justices to explain their reasoning, express their personal views, and take public responsibility for their analysis. They contribute to the development of law through detailed reasoning, doctrinal analysis, and individual perspective.

Per curiam opinions lack individual attribution, suggesting either that no single justice wishes to claim authorship or that the decision is so clear that individual exposition is unnecessary. The lack of attribution reduces accountability—no individual judge is responsible for the reasoning. It also reduces the opinion’s value as precedent, since the reasoning may be less detailed and the author’s perspective unavailable.

Important constitutional decisions are rarely issued per curiam. Major cases receive signed opinions with full reasoning to guide lower courts, explain the decision to the public, and contribute to legal development. The choice between per curiam and signed opinions reflects judgments about the case’s importance, the need for detailed reasoning, and the value of individual attribution.

Criticism and Controversy

Per curiam opinions have attracted criticism. They may obscure disagreement among judges, since the court may be unanimous in result but divided on reasoning. A per curiam opinion may conceal important differences in approach that would be revealed in separate opinions.

The lack of attribution reduces accountability—no individual judge is responsible for the reasoning. Critics argue that this undermines judicial accountability and reduces the quality of reasoning. Judges who would not sign their names to certain reasoning may accept unsigned opinions that advance their preferred result.

In the U.S. Supreme Court, some per curiam decisions have involved significant constitutional questions, leading to criticism that the form obscures the import of the decision. The most notable example is Bush v. Gore (2000), which effectively decided the presidential election. The per curiam form of that decision was criticized as an attempt to mask the controversial nature of the ruling.

Comparative Practice

Per curiam practice varies across jurisdictions. The European Court of Justice issues single judgments without separate opinions; all judgments are effectively per curiam, emphasizing the court’s collective authority and maintaining secrecy of deliberation. The ECJ’s single-judgment form reinforces the authority of its decisions and discourages individual judges from grandstanding.

The European Court of Human Rights issues both Chamber and Grand Chamber judgments without dissents, though separate opinions are now permitted. The original prohibition on dissents reflected the civil law tradition of anonymous collegial judgments. The ECtHR now permits concurring and dissenting opinions, though the judgment itself is not attributed to a specific judge.

Civil law appellate courts typically issue collective judgments without individual attribution, consistent with the civilian tradition. The judgment is the decision of the court, not of any individual judge. Dissenting opinions are rare or prohibited, preserving the appearance of unanimity and institutional authority.

Common law courts generally maintain individual signed opinions as the norm, reflecting the common law tradition of individual judicial authorship. Signed opinions allow judges to express their reasoning, take responsibility for their decisions, and contribute to legal development through individual analysis.

Per Curiam in International Tribunals

International courts vary in their use of per curiam opinions. The International Court of Justice issues judgments with individual opinions allowed, so per curiam is rarely used. ICJ judgments are attributed to the court but typically include separate opinions by individual judges.

The International Criminal Court permits separate opinions, and the ICC’s judgments identify the authoring judge. The ICC has not developed a per curiam practice, reflecting the common law influence on its procedures.

The WTO Appellate Body issued unsigned single opinions as a collective body, resembling per curiam opinions in form if not in brevity. The Appellate Body’s decisions were carefully reasoned and detailed, and the unsigned form reflected the collective nature of the body. The choice between individual and collective opinions reflects deeper jurisprudential values about judicial individuality and institutional authority.
