USPS Ballot-Mail Restrictions Blocked by Preliminary Injunction

For postal employees, the practical message is narrower than the political debate: follow the latest written USPS instructions for your assignment. Do not independently enforce the paused requirements, and do not invent local ballot-verification or voter-list procedures.

This page originally analyzed President Trump’s March 31 executive order while USPS was still reviewing it. USPS proposed a rule in June, finalized it in August and amended the Domestic Mail Manual with new standards for ballot mail used in federal elections. The rule then moved in and out of enforceable status as separate court proceedings developed.

On September 6, the administration renewed its emergency request to the Supreme Court. Justice Ketanji Brown Jackson set a Wednesday, September 9 response deadline, according to Reuters. A request to lift the injunction is not itself an order lifting it.

How the case reached this point

The Supreme Court’s August 24 ruling stayed an earlier injunction on procedural grounds because that challenge came before USPS completed its rulemaking. It did not approve the substance of the policy. After USPS published its final rule, states and voting-rights organizations amended or renewed challenges against the completed agency action.

On August 27, U.S. District Judge Indira Talwani issued a temporary restraining order blocking core portions of the final rule for 14 days. The court found that the challengers were likely to succeed on claims that USPS lacked authority to impose the requirements and that implementation so close to the election created a risk of irreparable harm.

The administration filed a notice of appeal on August 28. After the district judge refused on August 31 to suspend her own order, the administration asked the First Circuit for emergency relief. The September 3 hearing was followed by the September 4 preliminary injunction described above.

The August 31 ruling also clarified an important boundary: USPS may continue developing and testing the portal, but it may not compel states to use the system while the temporary order remains in force.

What the September 1 whistleblower disclosure alleges

Senator Richard Blumenthal released a letter to Postmaster General David Steiner and a disclosure submitted by attorneys for an anonymous federal official who says they have direct knowledge of the portal project. These are allegations, not findings by a court, the USPS Office of Inspector General or another completed investigation.

The disclosure alleges that USPS began building the portal around June 15, paused some work after the June 25 injunction and resumed development in late July before the Supreme Court lifted that injunction. It also says the complete system did not reach the customer-acceptance testing environment until the week of August 24, leaving less than a week before the planned September 1 launch target.

The most consequential allegation concerns batch verification. According to the disclosure, the planned process uses a zero-percent-error standard when workers sample physical barcodes. A single failed scan could cause an entire batch containing thousands of otherwise valid ballot envelopes to be rejected and returned to the election office for correction and resubmission.

The disclosure also alleges that development teams worked in silos, project requirements continued changing as late as August 21 and the finished system required two separate controls to fully switch off its verification functions. Blumenthal asked Steiner for project records, communications about testing and vulnerabilities, and legal guidance concerning work performed while injunctions were in place.

What the final USPS rule would require

If enforceable, the rule would apply to mail-in or absentee ballots for federal elections sent through USPS. It creates preparation, data and acceptance requirements for election officials and other authorized ballot mailers.

• Official Election Mail logo: Outbound and return federal ballot envelopes would display the approved logo.
• Automation-compatible envelopes: Ballot mail would meet applicable machinability and preparation standards.
• Unique Intelligent Mail barcodes: Outbound and return envelopes would use unique IMbs associated with the ballot-mail record.
• Federal Ballot Mail Portal: Authorized users would provide required mailing data, including recipient information and associated barcodes.
• Acceptance verification: USPS would review outbound federal ballot mailings before acceptance for compliance with the preparation and portal requirements.

The final text says outbound federal ballot mail would be presented at a business-mail acceptance facility or USPS retail counter for qualifying acceptance verification. Those core requirements are among the provisions affected by the temporary court order.

What USPS says it would not do

The final rule says USPS would not determine voter eligibility or citizenship, maintain state voter rolls, decide whether a returned ballot should be counted, open sealed ballot mail, inspect how someone voted or collect party affiliation.

USPS describes the process as verification of the mailpiece and information entered for that mailing—not an investigation of the voter. State and local election officials would remain responsible for deciding who is eligible to receive and cast a ballot under state law.

What the Supreme Court decided

On August 24, the Supreme Court granted the federal government’s request to stay an injunction entered in Trump v. California while the appeal continues. The order focused on whether the states’ challenge to the executive order was ready for judicial review before the agencies completed their work.

The Court did not hold that the executive order or final USPS rule is lawful. Its opinion said later challenges could test the agencies’ completed implementation. The August 27 temporary restraining order arose after plaintiffs challenged the finalized rule itself.

What it means for postal employees

Retail clerks and BMEU employees: These positions would be most directly connected to the new acceptance process if it becomes enforceable. For now, use the current written acceptance instructions and established escalation channels. Portal development or testing does not, by itself, authorize employees to impose the paused requirements. Do not rely on a news article or social-media summary to decide whether a mailing qualifies.

Plant clerks and mail handlers: Continue using the election-mail identification, visibility, scanning and processing instructions currently issued for the operation. Do not add a hold or rejection step based solely on the paused rule.

City and rural carriers: Nothing in the final rule authorizes an individual carrier to decide whether a voter is eligible or to independently hold back a ballot. Continue following current election-mail handling and delivery instructions. Escalate an unclear or damaged piece through normal supervision rather than improvising.

Supervisors and managers: Keep the operational message narrow. Employees need current acceptance, processing and delivery instructions—not political arguments about the rule. Do not tell employees to enforce paused provisions unless USPS issues lawful, current instructions following another court change. Distribute updated direction promptly and document the briefing.

What employees should do now

1. Follow written USPS election-mail instructions applicable to your assignment.
2. Do not create a local voter list, eligibility check or ballot-hold process.
3. Escalate acceptance questions through the designated BMEU, retail or election-mail channel.
4. Watch for updated written instructions as court orders and appeals develop.
5. Remain politically neutral while on duty and when acting in an official capacity.

NALC stated August 25 that letter carriers will continue delivering for the public while the court process unfolds. Whatever an employee’s personal opinion, the safe operational rule is the same: use official procedures, protect the mail and do not add requirements USPS has not lawfully placed into effect.
