To find a federal climate lawsuit filing, search the court’s own docket if you know where the case was filed; otherwise, use PACER’s nationwide Case Locator to identify the court and case number. For a U.S. Supreme Court case, search the Court’s official docket by case name or docket number, then use the docket’s envelope icon to sign up for email notifications.
Choose the right court search
Start by determining whether the case is in federal or state court. This guide covers federal court records and the U.S. Supreme Court. State courts maintain separate docket systems, so a state climate lawsuit must be searched through the relevant state court portal.
| What you know | Where to start | Update timing |
|---|---|---|
| You know the federal court where the case was filed | Search that court’s PACER/CM/ECF system | PACER says specific-court information is updated immediately. PACER: Find a Case |
| You do not know the federal court or case number | Search the PACER Case Locator | The nationwide locator is updated daily. PACER: Find a Case |
| The case is before the U.S. Supreme Court | Use the Supreme Court’s Docket Search | Search by docket number, case name, or words in a docket report. Supreme Court Docket Search |
A PACER account is required to access federal case records. The Case Locator is useful for finding the venue, but the specific court’s docket is the better place to check for the latest activity when you know where the case is pending.
Find a federal climate lawsuit filing
- Search by party or case name. Use the PACER Case Locator if you do not know the court. PACER allows searches by party, case number, nature of suit, and date fields. PACER Case Locator FAQs
- Confirm the case identity. Note the court and case number from the results. Once you have a case number, search with it rather than a common party name; that helps avoid unrelated cases with similar names.
- Open the detailed docket. Follow the result to the court’s CM/ECF record. Locator results link to more detailed case information there. Review the docket text and open the underlying document when it is available. PACER Case Locator FAQs
- Check the entry type and date. A docket entry may be a party’s brief or motion, a court order, or an opinion. The entry’s label and linked document tell you what was filed or decided; a new entry does not automatically mean the court has ruled on the case.
If the Case Locator does not find a party, PACER advises contacting the federal court where you believe the case was filed. A state-court case will not be found through this federal search workflow.

- Open the individual case docket. It lists filings and rulings in chronological order; electronic images are available for most submissions made after November 13, 2017. Supreme Court Docket Search · About Supreme Court Dockets
- To receive updates, select the envelope icon on the case docket and complete the email confirmation step. Notifications cover new filings or court action in that case. Supreme Court Docket Search
Understand what a docket entry means
The docket is the case’s chronological record, not a running summary of who is right. A party filing states that party’s position; it is not a judicial finding. A motion asks the court to take an action, while an order is a court ruling that often resolves a motion or petition. An opinion explains the Court’s reasoning in a decision. Check the linked document before describing an entry as a ruling or treating an argument as an established fact. About Supreme Court Dockets
Set up alerts and verify changes
For a pending Supreme Court case, use the case-specific email subscription on its docket page. In lower federal courts, check the relevant court’s CM/ECF page for RSS availability: some courts offer free RSS notifications that summarize activity and link to the document and docket report. Opening linked records still requires PACER login. PACER Case Locator FAQs

Before relying on an update, check the official docket itself. PACER’s nationwide locator updates daily, while information in a known specific court is updated immediately, according to PACER. Court dates and filings can change, so an alert or search result is a prompt to verify the current docket, not a substitute for it.
Current example: Boulder County v. Suncor
The Supreme Court docket for County Commissioners of Boulder County v. Suncor Energy (U.S.A.) Inc., No. 25-170, illustrates why the docket’s dates and entry types matter. According to the docket, the Court granted the petition on February 23, 2026, and directed the parties to brief and argue an added question: “Whether this Court has statutory and Article III jurisdiction to hear this case.” The petitioners’ merits brief was filed May 14, 2026, and the respondents’ brief was filed July 27, 2026. The docket scheduled argument for October 5, 2026. Its latest listed entry, dated September 28, 2026, is a clerk’s letter to counsel noting that Justice Alito will not continue to participate in the case. Supreme Court Docket Search

PACER says transcripts are added to the system 90 days after they are produced. During that period, contact the clerk’s office to ask about inspecting a copy or obtaining one from the reporter or transcriber. This transcript delay does not describe the timing of ordinary docket entries. PACER Case Locator FAQs
