Across its full history, the U.S. Supreme Court has issued somewhere between 25,000 and 30,000 written opinions, and in the modern era it decides roughly 60 to 80 cases each term. How many Supreme Court cases there have been depends heavily on what you count as a “case,” because the Court produces several different kinds of decisions and its early records are incomplete.
The Historical Total Is a Range, Not a Number
No single authoritative database claims a precise lifetime total for the Court, and the 25,000 to 30,000 range reflects the best available estimates rather than a verified count. The figure moves depending on what gets included. Signed majority opinions, where a named justice explains the reasoning in full, are one category. Per curiam opinions, unsigned and issued in the Court’s name, are another. Summary dispositions, where the justices resolve a case without oral argument or full briefing, are a third. Add them all together and you get a large number. Restrict the count to signed, fully argued opinions and it shrinks considerably.
Record-keeping has also changed over the centuries. The earliest terms produced only a handful of decisions, and some early records are incomplete. The Court’s first decided case was West v. Barnes in 1791, a unanimous ruling on the procedural requirements for a writ of error.1Justia U.S. Supreme Court Center. John Jay Court (1789-1795) The more familiar Chisholm v. Georgia, often cited as an early landmark, came two years later.2Justia U.S. Supreme Court Center. Chisholm v. Georgia, 2 US 419 (1793)
How Many Cases the Court Decides Each Term
Each Supreme Court term begins on the first Monday in October and typically wraps up by late June or early July.3Supreme Court of the United States. The Court and Its Procedures Inside that window, the modern Court issues roughly 60 to 80 merits opinions. The 2024–2025 term produced 67 opinions as of the end of June 2025, and the 2023–2024 term saw about 62 cases accepted for argument. Output has been remarkably consistent from year to year under the Roberts Court.
That is a sharp drop from the 1970s and 1980s, when the Court routinely decided 150 or more cases per term. Legal disputes did not dry up. What changed was how the justices use their discretion. Congress stripped away most of the Court’s mandatory appellate jurisdiction in 1988, so almost every case on the docket today is there because the justices chose to hear it. With that freedom, they have narrowed their focus to disputes involving genuine conflicts between lower courts or questions of broad national significance. Each side gets 30 minutes for oral argument, and the justices are not inclined to spend that time on cases they view as straightforward.3Supreme Court of the United States. The Court and Its Procedures
The Shadow Docket Adds to the Count
The merits docket does not capture the full picture of what the Court decides. The justices also handle a separate orders list that includes emergency applications, stays, and other procedural matters resolved without full briefing or argument. This part of the docket, sometimes called the shadow docket, has drawn increasing public attention because some of those orders carry major legal consequences despite the abbreviated process. If you are counting decisions rather than argued opinions, this workload matters.
Petitions Have Fallen Sharply
One of the least-discussed changes at the Court is how steeply incoming petitions have fallen. Older sources that say the Court receives 7,000 to 8,000 petitions per year were accurate a decade ago but are out of date. Total filings peaked around 2006–2007, when the Court received well over 8,000 petitions. By the 2024–2025 term, that number had dropped to about 3,856.
The decline is driven overwhelmingly by the in forma pauperis (IFP) docket, which covers petitioners who cannot afford the filing fee. IFP filings dropped nearly 65 percent from the 2006–2007 term to the 2024–2025 term, falling from over 7,100 to about 2,527. The paid docket, where petitioners pay the $300 filing fee and submit printed booklet-format briefs, declined by a smaller margin of roughly 23 percent over the same period, landing at about 1,329 petitions in the 2024–2025 term.
The reasons are debated. Some researchers point to changes in federal habeas corpus law that reduced the pool of eligible prisoner petitions, which historically made up a large share of the IFP docket. Others note that the Court’s consistently low acceptance rate for IFP cases, roughly 99 percent denied, may discourage some would-be petitioners from filing at all. Paid petitions face a denial rate closer to 86 percent, still steep but meaningfully better.
Original Jurisdiction Cases Are a Separate, Tiny Category
Almost every case the Supreme Court hears arrives on appeal, but a narrow category of cases can start at the Court itself. Original jurisdiction covers disputes between two or more states, cases involving ambassadors and foreign officials, and certain controversies between the federal government and a state.4Office of the Law Revision Counsel. 28 USC 1251 – Original Jurisdiction Only the state-versus-state category is exclusive to the Supreme Court; the others can also be filed in lower federal courts.
These cases are vanishingly rare. Between 1789 and 1959, the Court issued written opinions in just 123 original cases. Since 1960, the Court has received fewer than 140 motions asking it to hear original cases, and it denied nearly half outright.5Federal Judicial Center. Jurisdiction: Original, Supreme Court They tend to involve things like water rights between neighboring states or boundary disagreements, the kind of conflict where no other court has the authority or neutrality to step in.
The appellate docket is where the volume lives. The Court can review final decisions from the highest court of any state when the case raises a federal constitutional or statutory question,6Office of the Law Revision Counsel. 28 USC 1257 – State Courts; Certiorari and it reviews decisions from the federal courts of appeals. That appellate function accounts for essentially the entire modern caseload.7Congress.gov. Constitution Annotated – ArtIII.S2.C2.1 Overview of Supreme Court Jurisdiction
