USPS Halts Development of Ballot-Verification System and Tells Staff It Will Not Enforce the Mail-Ballot Rules in 2026, Postmaster General Steiner Says

On September 17, 2026, Postmaster General David Steiner told the Associated Press that the Postal Service has stopped work on the voter-verification computer system central to the Trump administration’s mail-ballot rules, three days after the Supreme Court denied the government’s stay application in USPS v. California (No. 26A305) 7-2 (2026-09-14–scotus-blocks-trump-mail-ballot-eo-7-2-kavanaugh-timing-midterms). “There’s an injunction so we’re not doing anything,” Steiner said. A memo sent to all Postal Service employees the same week and obtained by the AP stated the agency will “not be enforcing any of these new rules in the 2026 federal election” and that “for Election Mail it is business as usual.”

What Happened / Key Facts

  • Steiner declined to assess the Supreme Court’s ruling and declined to take a position on the underlying policy, describing himself as leading an “independent agency of the executive branch” whose role was limited to “the execution side.”
  • He said he had read only “portions” of the Blumenthal whistleblower report alleging the system was built in a rushed, error-prone process (2026-09-01–usps-whistleblower-alleges-work-continued-after-talwani-order), and said he had planned to unveil the system around September 15 — the week the Supreme Court blocked it.
  • Steiner denied resignation rumors amid what he described as pressure from people who “would like to see me out of a job,” without naming a source.
  • He said USPS will continue to recommend (not require) the barcode/envelope design changes going forward, with a price differential: lower postage for compliant envelopes, higher for noncompliant ones needing manual processing — a voluntary, price-incentive version of the design requirement the enjoined rule would have mandated.
  • Per the same reporting, Justice Kavanaugh’s concurrence is characterized as leaving open that he “might rule in favor of the administration if the issue comes back before the court at a later time” — consistent with the canon entry’s own reading of the concurrence as timing-based rather than authority-foreclosing.
  • Separately noted in the same report: mail-ballot rejections for late postmarks have risen in Washington and Oregon; Steiner said no operational changes are planned and encouraged early voting (“Everything is solved if people vote early”).

Why This Event Matters

This is the concrete “administration response” signal the canon entry’s own analysis called for: not a refiled rule with more lead time, and not a post-election revival attempt, but an operational stand-down for 2026 with the pricing-incentive substitute left in place. It is consistent with — not contradictory to — the canon entry’s finding that the ruling foreclosed timing, not authority: USPS is complying with the injunction as narrowly construed (no enforcement this cycle) while preserving the underlying design preference through a non-mandatory price lever that requires no judicial authorization to operate. Whether a mandatory version returns for 2028 remains the open question the canon entry identifies; this entry documents the interim posture, not an answer to it.

Research Gaps

  • Whether the “memo to all postal employees” is independently obtainable (only characterized via AP paraphrase in current sourcing).
  • Whether the price-differential compliance incentive is itself challenged or challengeable — no litigation on it identified as of this entry.
  • Track for any 2027 rulemaking notice reviving the mandatory design/pre-clearance requirement with a longer lead time, per the canon entry’s own forward-looking flag.
