The administration asks the Supreme Court to lift a new block on mail-ballot rules

The order first, then the rule, then the Court

What happened

On March 31, 2026, President Donald J. Trump signed Executive Order 14399, "Ensuring Citizenship Verification and Integrity in Federal Elections." Section 3 of that order directed the Postmaster General to start a rulemaking on mail-in and absentee ballots, including a proposed line that the Postal Service "shall not transmit" those ballots from anyone not enrolled on a state-specific list. The order set its own clock: any final rule "shall be issued no later than 120 days from the date of this order," which was July 29.¹¹

An older case was already running. In August 2020 the NAACP sued the Postal Service over ballot delivery delays, and in December 2021 the two settled. The Postal Service's statement that day said it "agreed to continue to prioritize monitoring and timely delivery of Election Mail for future elections"; the final rule describes the same promise as running "through 2028." In 2026 the NAACP asked the D.C. federal court to enforce that settlement against the proposed rule. On July 1 that court found the proposed rule would violate the settlement and blocked it. On July 17 the D.C. Circuit, in what Talwani calls "a one-paragraph order," stayed that ruling: the government had "made a strong showing" that the challenge was not ripe with no final rule issued and that the order likely would not break the settlement. That appeal is pending. It is a contract case, not a constitutional one, it sits in Washington, not Boston, and it is not before the Supreme Court in 26A305. Now that a final rule exists, the ripeness point the D.C. Circuit relied on no longer holds in the same form.^46251210

The rule did not go straight from the order to the Federal Register. On June 2 the Postal Service published a proposed rule; more than 200,000 comments came in. On June 25 Talwani ruled for 23 states and the District of Columbia in their suit against the order, and on July 7 she entered a final judgment forbidding the named agencies from carrying out Sections 2 and 3, but only for those plaintiffs and only for elections through November 3. On July 25 the First Circuit refused to pause that judgment while the government appealed. Its order said the government and twelve intervening states argued "only that the Plaintiff States lack standing to bring their claims and that those claims are not ripe," and closed: "We deny their motions."¹⁰²³

On August 11, in the separate case brought by the League of Women Voters, Talwani entered a nationwide preliminary injunction. It barred the Postal Service defendants "from implementing, giving effect to, or enforcing Section 3" of the order for the November 3 election or any earlier one, and from "initiating or completing rulemaking" on the regulations the order described.¹⁰

On August 21 the Postal Service issued a final rule, Ballot Mail for Federal Elections, and made it effective that day. The rule was published in the Federal Register on August 26. It amends the Domestic Mail Manual. It requires official Election Mail logos, automation-compatible envelopes, unique Intelligent Mail barcodes, and an online Federal Ballot Mail Portal where election officials enroll the name, address, and barcodes of people they intend to send a ballot. That was 23 days after the order's own deadline. Both injunctions were still in force that Friday evening. The rule's own text said the Postal Service would not implement it for the 2026 election "unless and until the government obtains relief from those injunctions." It also says the Postal Service is exempt from notice-and-comment rulemaking under 39 U.S.C. 410(a) but invited comment anyway, and that it took effect at once because "Delaying the effective date would jeopardize implementation of this rule in time for the 2026 general election."¹²²²¹²

Four days later Talwani ruled that issuing the rule broke her August 11 order. The League of Women Voters had moved to enforce the injunction. The government answered that the rule would not be enforced for 2026 unless the injunctions were lifted. Talwani wrote that those arguments "ignore the court's explicit directive not to" initiate or complete rulemaking, and that "the court finds that Defendants violated the preliminary injunction in this case." She imposed "no remedy other than identifying the violation."²²

Outbound mailings presented by election offices that do not comply "will not be accepted" and "will be returned" to the "authorized ballot mailer." Section 705.24.5 "does not apply to Return Federal Ballot Mail." Return envelopes still have design rules; the batch nonacceptance screen is the outbound procedure.¹²

The rule states an "express exclusion of UOCAVA ballots" from its scope. The Postal Service wrote that those voters "will experience no change" if the exemption is applied as written. UOCAVA covers uniformed and overseas voters under 52 U.S.C. 20302.¹²³⁰

The portal sits on a federal Privacy Act system, "USPS 820.225 Federal Ballot Mail." The July 17 notice places it at "USPS Headquarters, Supplier cloud" computing environment. The first category of records is "Mail in voter information: Name," address, unique Intelligent Mail barcode numbers, and originating election-office state. Records are retrievable by name, address, issuing state, and barcode, and "Records are retained for 5 years." A stated purpose is to help determine adherence to federal law and facilitate law-enforcement efforts. State and local officials load the rows, and not only officials: the rule defines a portal user as the state's chief election official and "any individual or entity, such as a mail service provider or an election official of that state or a political subdivision thereof, authorized by the chief election official" to enter information. "Voters themselves will not enroll," the rule says. What the rule does not set out is who inside that chain can see what, whether access is logged, what happens on a breach, or what a vendor keeps. The system is not a citizenship file. The Postal Service's September 1 response to comments said the system is effective with that publication.¹⁴¹⁵¹²

On August 24 the Supreme Court granted application 26A124, staying the July judgment for the states. A stay is an order that pauses another court's order. The unsigned opinion said the government was likely to win its argument that the district court lacked jurisdiction: "Two related doctrines of justiciability block the States' suit," standing and ripeness, and the Court took "each challenged provision of the Order separately." On Section 3, the Postal Service directive, it held that the district court had relied on "a string of speculations" about a rule that had not yet issued, and wrote that "Federal courts review final rules, not proposed rules." The intervenor states' own application, 26A139, was "denied as moot" the same day. The opinion added that the disposition "does not mean that any measure taken by the Government to implement the Order will necessarily be lawful."⁹¹⁸

That stay did not reach the August 11 injunction, which stood in the League of Women Voters case. On August 26, the day the rule was published, Talwani vacated that injunction. The same day, Sauer's application recounts, "the LWVMA respondents filed a supplemental complaint, and the California respondents filed a new action," both aimed at the issued rule, and both asked for a temporary restraining order. The August 27 order and the September 4 injunction come from those filings.¹

On August 27 Talwani entered a temporary restraining order against mandatory parts of the new rule. On September 3 Sauer asked the Court, in application 26A297, to stay that order. The docket shows the application was submitted to Justice Jackson. She set a response for September 8. The emergency docket is the Court's fast track for those requests, usually without a full argument.⁴

On September 4 Talwani issued a preliminary injunction. A preliminary injunction is a court order that forbids someone from doing something while a lawsuit continues. This one names specific Domestic Mail Manual sections and applies to elections on or before November 3. She dissolved the August 27 temporary order the same day. These holdings are preliminary findings for that order, not a final judgment on the merits.¹⁰

Why the judge blocked it

Talwani wrote under "Likelihood of Success on the Merits" that the plaintiffs had established a substantial likelihood of success on their Elections Clause claim. She found the rule is an election rule that regulates the time, place, and manner of elections, and that it is unconstitutional where Congress has not authorized such a rule under the Elections Clause.¹⁰

She separately found the rule likely ultra vires, meaning beyond the agency's statutory authority: Congress has not authorized the Postal Service to make this election rule, and Title 39 does not grant that power.¹⁰

The government contests those findings. In application 26A305, Sauer writes that "The Rule is a lawful and modest exercise" of rulemaking authority Congress delegated to the Postal Service, that "it regulates the U.S. Mail, not federal elections," and that "it does not regulate state administration of elections."¹

The rule gives its own reason, which the order's finding of "no evidence relating to" fraudulent mail voting answers but does not quote: "Whether or not voter fraud is common or uncommon, the Postal Service has the legal authority to take the measures in this rule to facilitate enforcement of federal law, reduce the risk of fraud, and help protect the integrity of federal elections."¹²¹⁰

She also found a conflict with state law that is larger than the citizenship question. California registers "confidential voters" whose information state law bars from any list; Arizona protects police officers, judges, and victims of sexual violence or stalking, and makes it a crime for election officials to release their information. Talwani wrote that the rule "directly conflicts with these state laws" and that the government made "no effort to explain how States can both comply with the requirement to upload voter information" and keep those addresses confidential. The Postal Service's answer on the record is the Privacy Act notice's stated law-enforcement purpose, not a carve-out for protected voters.¹⁰¹⁴

On September 6 Sauer wrote the clerk that the United States was withdrawing 26A297, and he filed 26A305 against the new injunction. Jackson's order on that docket set any response for 4 p.m. Eastern on September 9. Sunday is 58 days before November 3, the federal election day named in the injunction and in 2 U.S.C. 7 as the Tuesday after the first Monday in November of an even-numbered year.²²⁹

Four stay applications, one election date

Where this sits

The Sunday application's caption lists 23 states, the District of Columbia, and Josh Shapiro, Governor of Pennsylvania, as plaintiffs. 12 states intervened on the government's side. Washington Attorney General Nick Brown's September 4 release said "25 states have secured a" preliminary injunction. That is the same coalition: Brown names 23 states, including Washington, plus the District of Columbia and Pennsylvania's governor. "25 states" is a loose label because the District of Columbia is not a state.¹⁴⁴

How far the injunction reaches is contested on its own. It binds the Postal Service for elections on or before November 3 and does not stop at the plaintiff states. In June 2025 the Supreme Court held in Trump v. CASA that universal injunctions "likely exceed the equitable authority that" Congress gave the courts, and allowed relief only as far as needed for "complete relief to each plaintiff with standing to sue." Sauer's application makes that argument here: "the California respondents alone are not entitled to universal relief against the Rule," and the states "cannot obtain relief nationwide" for ballots mailed by other states. The order's answer is the second case, brought by the League of Women Voters and other organizations with members across the country; Sauer says those groups have not shown standing at all. Whether one Postal Service rule can run in some states and not others, and whether the organizations' members need nationwide protection, are questions the Court could decide without reaching whether the rule is lawful.²⁸¹¹⁰

August 24 was a win on procedure, not on the rule. The Court stayed the judgment against the executive order on jurisdiction, provision by provision. For the Postal Service section it said the states' injury rested on a "string of speculations" about a rule that had not issued; the other sections fell on standing. The Postal Service had already issued that rule and made it effective on August 21, 3 days before the opinion. The 26A124 docket this story cites lists no filing between August 12 and the August 24 opinion, so the records do not show whether the justices were told the rule had issued before they wrote that it had not. The rule reached the Federal Register 2 days after the opinion, on August 26. Talwani then enjoined named sections of that rule. Sunday's application argues that the new injunction is "materially identical" to the August 27 temporary order and that the Postal Service is regulating mail, not elections.⁹¹⁸

The dates leave little room. The executive-order chapter of this fight starts with the March 31 order and runs through a June proposed rule, a July judgment, and two August injunctions before the rule issued; the settlement chapter starts in 2020. Sunday's stay request was filed 58 days before the election the injunction names, and 3 days before Jackson's response deadline. September 19 is the UOCAVA statutory mailing date, 13 days after the filing; the rule's "express exclusion of UOCAVA ballots" means that date is not a deadline this rule imposes.²¹²

Election offices, outbound ballots, and the next few days

Who feels it

The immediate dispute is narrower than mail voting as a whole. The rule reaches outbound ballot mailings that election offices present to the Postal Service for a general, special, or runoff election for federal office. Its definition "does not include primary elections." UOCAVA ballots are excluded. The verification section "does not apply to Return Federal Ballot Mail," so the envelope a voter sends back is outside it, and state-only elections are not federal elections under the rule. The injunction is what keeps the Postal Service from treating noncompliant outbound mailings as unaccepted for elections on or before November 3. If the Court stays that injunction, offices sending those outbound ballots would have to meet the envelope and portal rules while some of those mailings are already moving. Sauer's own line is that once envelopes "enter the mailstream, there is no retrieving them."¹¹²

What was old, what is new. The envelope half of the rule is not new practice. The Postmaster General wrote that "The USPS has recommended both aspects for years (see the USPS Kit 600)," that states from Oregon to Florida already prepare ballots that way, and that the House passed a bill requiring a unique barcode and envelope design in 2024 by 396 to 6. On the list half he wrote that the state-provided list "is merely a list of voters that a State says are receiving a ballot through the mail" and that "matching a manifest to the actual shipped product is also not fundamentally new." What is new is the word must: recommended designs become conditions of acceptance, every mail voter's name and address goes into a federal system kept five years, and a mailing that fails the check "will not be accepted." The dispute is not ordinary mail against new technology; it is voluntary practice made mandatory, plus a records system, weeks before ballots move.²¹¹²¹⁴

What the whistleblower alleged. An anonymous USPS whistleblower, in a disclosure Senator Richard Blumenthal released on September 1, said the portal work was rushed and siloed, that the project parts "have not undergone meaningful testing," and that USPS adopted a "zero-percent failure threshold" under which one failed barcode could return an entire batch: "if a barcode scanner fails to correctly read one barcode in a batch, the entire batch is rejected and returned to the state." Those are allegations, not established facts.¹⁶

What a second account said. ProPublica reported on September 2, from a person familiar with the internal meetings, that "Some in the meetings recommended trying to limit harm to voters by not rejecting the entire batch." Two people who attended a committee meeting told ProPublica that, on the example of Maricopa County's initial mailing, "USPS officials confirmed it was possible that one ballot with a bad barcode or wrong voter information within the more than 2 million ballots could delay the entire mailing." That account is separate from the whistleblower's and is also anonymous.⁴⁵

What the whistleblower's lawyers told the Court. On September 8 Whistleblower Aid filed an amicus brief on the 26A305 docket. It describes two chokepoints: a portal check before a batch reaches a post office, and a counter check where clerks scan a sample. It says "the verification standard is zero percent failure," that "the unit of rejection is the batch, not the ballot," and that the systems as designed "reject entire batches of ballots if they find even a single mismatch." The sampling schedule it quotes from the disclosure, still provisional a week before the planned September 1 launch, is in the table below.²⁰

• What the whistleblower's lawyers told the Court. On September 8 Whistleblower Aid filed an amicus brief on the 26A305 docket. It describes two chokepoints: a portal check before a batch reaches a post office, and a counter check where clerks scan a sample. It says "the verification standard is zero percent failure," that "the unit of rejection is the batch, not the ballot," and that the systems as designed "reject entire batches of ballots if they find even a single mismatch." The sampling schedule it quotes from the disclosure, still provisional a week before the planned September 1 launch, is in the table below.²⁰

What the Postal Service said. On September 1 the Postal Service said it had "spent months developing a U.S. Federal Ballot Mail Portal," that the work "has at all times been conducted in a manner consistent with court orders," that it was "finalizing the portal" for officials who "voluntarily wish to familiarize themselves," and that "verification procedures prior to acceptance are not being performed."¹⁷

What the Postmaster General said. On September 4 David Steiner answered the whistleblower directly. He wrote that the state-provided list "is merely a list of voters that a State says are receiving a ballot through the mail," that "Testing and validation have been continuous throughout the development lifecycle," that "our standards for quality, security, and system integrity were not compromised," and that "our process requires that deployment be delayed whenever significant defects or security vulnerabilities are identified." He did not say what was tested or publish results.²¹

What would settle it. Test reports, a defect list, the sampling specification, or a production record. Neither side has put any of those on a docket this story cites. Until one does, the readiness of the portal is a contested claim on both sides, not a fact. The first independent look is now on the calendar: on September 8 the Postal Service's Office of Inspector General said it plans "an independent review of these allegations." It has published nothing yet. Its audit of the 2026 primaries, which did not evaluate the rule, found on-time election-mail processing "ranging from 97.75 to 98.99 percent" from February through May, and said the office would "cover allegations received at the end of August 2026 in subsequent work." That is the baseline the portal would be added to.^20214727

What the court found. Talwani wrote that the "Portal is not currently operational" and that the "absence of an appeals or escalation process" supported the states' irreparable-harm claim. The compressed approval and enrollment process, she found, supported blocking mandatory use through November 3.¹⁰

What a refused batch means, step by step. The rule does not say a refused ballot is dead. It says a mailing that fails verification "may be temporarily rejected (and thus not permitted to enter the mailstream), any errors may be corrected and the mailpieces will thereafter be accepted for mailing." So the chain runs: the batch is refused; the office finds and fixes the error and presents the batch again; the mailing goes out late; a voter gets the ballot late or not in time; whether that voter can still vote depends on state law. The plaintiffs' case is that the middle steps are not realistic on this calendar: whole batches turned back for one mismatch, envelopes that take "four to sixteen weeks" to reprint, and, in Talwani's words, the "absence of an appeals or escalation process." A refused batch is a delay first and a lost vote only if the delay outruns the calendar.¹²¹⁰

How many ballots. Talwani's order says "millions" without a national count, and none exists yet for 2026. Two things do exist. The states' own forecasts are in the injunction record: California expects to mail "more than 23 million" ballots, Washington "approximately 5.1 million," Colorado "more than 4,000,000," Oregon "approximately 3 million." The order also says the rule would reach "10,000 different election jurisdictions" and that printing new envelopes takes "four to sixteen weeks." For scale, the last midterm's federal survey counted 61,460,139 mail ballots sent in 2022 and 36,683,450 returned. That is a baseline from a different year, not a forecast for this one.¹⁰²⁴

Election offices that use the mail would have to reprint envelopes, load the portal, and certify designs if the stay is granted. Talwani wrote that the record includes "no evidence relating to" fraudulent mail voting to support rushing the rule. The injunction leaves voluntary compliance open.¹⁰

After Sunday

What happened next

On September 8 the 26A305 docket added three amicus briefs: from bipartisan current and former members of Congress, from the Society for the Rule of Law, and, in the evening, from Whistleblower Aid. The Congress brief argues that the order and final rule usurp Congress's constitutional role as the ultimate authority on federal-election administration. The Society for the Rule of Law brief argues that in the Help America Vote Act, the National Voter Registration Act, and the Voting Rights Act, "Congress specifically preserved authority concerning these election practices" for the states, and that a provision of the Help America Vote Act "specifically superseded resort to all the Title 39 non-election provisions on which Applicants" rely. The Whistleblower Aid brief puts the disclosure's account of batch rejection and sampling before the justices. Jackson's response deadline remains 4 p.m. on September 9; as of Tuesday evening the docket showed no response and no stay order.¹³¹⁹²⁶

Also on September 8, the Postal Service's Office of Inspector General, which is separate from the Postal Service, said in a statement carried by Democracy Docket that it had "received the whistleblower allegations" about the Postal Service's implementation of the executive order and was "currently analyzing the information and plan to conduct an independent review of these allegations." Reuters reported the same plan the same day. The office did not call it an investigation, set no date, and has published no finding. The announcement does not say the allegations are true; it says someone outside the dispute will look.⁴⁷⁴⁸
