Supreme Court Stays Injunction Blocking Trump Administration’s Mail-Ballot Executive Order: Midterm and New York Implications

On August 24, 2026, the Supreme Court stayed an injunction issued by the U.S. District Court for Massachusetts which enjoined the federal government from implementing President Trump’s recent order regarding mail-in ballots. The decision was issued per curiam with three dissents and, collectively, consists of 37 pages. The decision has been widely, and confusingly, reported in the press. This alert explains the decision and clarifies what the Supreme Court has, and has not, ruled.

The President recently issued Executive Order No. 14399 (91 Fed. Reg. 17125 (2026) (the “Executive Order”) regarding elections. A group of states sued the federal government in the District of Massachusetts, contending that the Executive Order unconstitutionally infringes on their authority to administer elections. The District Court agreed and enjoined the federal government from implementing the Executive Order. The federal government asked the Supreme Court to stay the injunction. The Court agreed and granted the stay.

The Court held the states lacked standing and the challenge was not ripe because the Executive Order is an internal executive directive, not a self-executing mandate. The ruling is on procedural grounds and not on the merits. It does not decide the Executive Order’s legality, does not affect a second, broader nationwide injunction issued in a separate suit, and leaves the door open to renewed challenges concerning the agency rule by the United States Postal Service (“USPS”) once (and if) finalized. The case now returns to the First Circuit Court of Appeals.

I. The Executive Order

The Executive Order is a directive from the President mandating that certain federal agencies pursue certain policies regarding mail-in ballots. Three provisions are at the center of the litigation:

1. Section 2(a) – Citizenship Lists: Orders the Secretary of Homeland Security to “take appropriate action to” create and send “State Citizenship List[s]” to each State, cataloging residents who are U.S. citizens and “who will be above the age of 18 at the time of an upcoming Federal election.”
2. Section 2(b) – Prosecutorial Prioritization: Requires the U.S. Attorney General to “prioritize the investigation and, as appropriate, the prosecution of State and local officials or any others” who issue federal ballots to ineligible voters.
3. Section 3 – USPS Rulemaking: Directs USPS to “initiate a proposed rulemaking” that includes several proposed provisions, including that outbound ballot envelopes must contain a unique barcode to facilitate tracking. It goes on that, “USPS shall not transmit mail-in or absentee ballots from any individual” voter unless a State has successfully enrolled that voter on a State-specific list.

All provisions of the Executive Order must “be implemented consistent with applicable law.” 

II. The Proceedings Below

Four days after the president signed the Executive Order, 23 States and the District of Columbia filed a lawsuit challenging the Executive Order as unlawful and seeking to enjoin its implementation, alleging that §§ 2 and 3 are ultra vires and also violate the Constitution’s Elections and Electors Clauses, the Tenth Amendment’s anticommandeering doctrine, and the separation of powers.

The District Court granted the motion for summary judgment by the Plaintiffs and issued a permanent injunction, barring implementation of §§ 2 and 3 only as to the states who were Plaintiffs and only for the 2026 election cycle. The District Court also concluded that the President lacked legal authority to implement §§ 2 and 3, and that his mandate impermissibly interfered with the Plaintiffs’ constitutionally assigned duty to administer elections.

The federal government appealed to the U.S. Court of Appeals for the First Circuit and also requested a stay of the injunction. In a 2-to-1 panel decision, the appeals court denied the stay request, concluding that the Plaintiffs had shown imminent injuries from resource diversion, pocketbook losses, the risk of prosecution, and federal interference with the Plaintiffs’ sovereign interests in conducting elections. The First Circuit further found that the balance of equities favored the Plaintiffs. The federal government then applied to the Supreme Court for a stay.

III. The Supreme Court Ruling

The Court granted the stay on standing and ripeness grounds, analyzing each section of the Executive Order separately.

A. Standing

1. No Standing: Section 2(a)

Section 2(a) directs the Secretary of Homeland Security to take appropriate action to create and distribute State Citizenship Lists. This provision is an internal directive from the President to a subordinate. The Court reasoned that it imposes no obligations on the States, so they “suffer no concrete harm from” it. And without concrete harm, the Court held that there is no standing. The true “source of any injury” to the States would be the downstream action that the Secretary “might take in the future” to implement § 2(a). Section 2(a) can be implemented only “[t]o the extent feasible and consistent with applicable law,” and the Court found that the chain of inferences necessary to support the States’ supposedly concrete injury was unduly long, including speculation about feasibility, the shape of implementation, and whether any action would ultimately harm the States.

The lower courts concluded that the States suffered “a present injury” from § 2(a) because it required them “to begin planning now on how to comply with” it. But the Court held that the States “cannot manufacture standing merely by inflicting harm on themselves based on their fears of hypothetical future harm that is not certainly impending.”

2. No Standing: Section 2(b)

The Court held that the States lack standing to challenge § 2(b) for much the same reason: It does nothing to them, according to the Court. This provision directs the Attorney General to “prioritize” the investigation and prosecution of those who violate existing federal laws by issuing ballots to ineligible voters. Setting prosecutorial priorities lies within the President’s Article II power, and his decision to prioritize the prosecution of certain offenses does not inflict a traditionally recognized harm on the States.

The States argued that § 2(b) credibly threatened them with prosecution if they did not use the Citizenship Lists from § 2(a). The Court rejected this, finding that because the States concede that § 2(a) does not require them to use the Lists at all, it is “logically impossible for a State to ‘violate’ § 2(a),” and § 2(b) does not suggest otherwise, absent a textual basis for their concerns, the States lack a well-founded fear that they will be prosecuted.

B. Not Ripe: Section 3

Section 3 orders USPS to initiate the process of proposing a rule that might bind the States in the future. It is not a proposed rule, let alone a final rule, and it imposes no legal requirements on the States or on anyone outside the Executive Branch. Federal courts review final rules, not proposed rules. If USPS’ final rule harms the States, they may challenge that rule.

C. Irreparable Harm and Balance of Equities

The Court also found that the remaining stay factors favor relief. The Court held that the federal government is likely to suffer irreparable harm without a stay because the injunction bars Homeland Security from trying to compile Citizenship Lists for about half the States, purports to forbid the Attorney General to implement the President’s enforcement priorities, and prevents USPS from initiating a rulemaking. Because reversal of the District Court’s judgment would come too late for the 2026 midterms, the District Court’s errors deal “a serious setback” to the Executive’s goals while this litigation unfolds.

The balance of equities does not counsel against awarding the federal government interim relief. The Executive Order makes no demand of the States, so staying the injunction will not concretely harm them.

D. The Court’s Caveat

The Court’s disposition does not mean that any measure taken by the federal government to implement the Executive Order will necessarily be lawful. Instead, the Court specifically noted that “time will tell” whether any measures taken to implement the Executive Order will withstand legal scrutiny. 

E. The Dissents

1. Justice Sotomayor’s Dissent (joined by Justice Kagan)

Justice Sotomayor emphasized that the Court’s decision does not address whether the President’s attempts to interfere with States’ administration of the November 2026 elections are lawful. It similarly does not suggest that the Executive Branch has any constitutional or statutory authority to implement the President’s directives. Instead, the decision merely postpones adjudication of those challenges.

“The clear import of §2,” according to Justice Sotomayor, is that the federal government will use the Citizenship Lists to initiate investigations and prosecutions, and that the federal government itself admitted the lists “might be used solely to facilitate this sort of post-election law-enforcement activity.”

Justice Sotomayor also identified an internal contradiction in the federal government’s position: even as it represented that it might not implement the Executive Order at all for purposes of defeating standing, it insisted that it needed emergency relief right now to immediately implement those changes. The federal government, she argued, could not have it both ways.

2. Justice Jackson’s Dissent

Justice Jackson argued that the District Court held the President’s Order unlawful, the federal government does not defend its lawfulness before the Court, and no judge or justice has held that the Executive Order comports with the Constitution. Yet the Court saw fit to grant the equitable relief on the grounds that, because the federal government had not yet issued a final rule at the time the complaint was filed, the Plaintiffs lacked a concrete injury. She stated that this ruling “violates well-established precedents concerning this Court’s equitable discretion and needlessly injects chaos and uncertainty into the upcoming midterm elections.” 

Justice Jackson observed that the Court has long held that valid election-related legal claims can come too late and noted the contradiction that the Court found that these claims were asserted too early. She criticized the majority for failing to explain when, exactly, is the right time to bring a meritorious election-rule claim. This trap of the Plaintiffs being deemed too early now could result in later challenges being denied because they are too late having brought the challenge too far along in the process and too close to Election Day (the Purcell v. Gonzalez problem). 

Justice Jackson described the practical effect of the Executive Order as requiring “a fundamental overhaul of the States’ existing mail-in ballot systems, changing from a state-administered process to one in which the Federal Government controls who gets a ballot and whose vote counts.” 

IV. Impact on the Midterm Elections

The timing and practical stakes of this ruling cannot be overstated.  The November 2026 midterm elections are imminent, and the stay has several immediate consequences:

1. Citizenship Lists may proceed. With the injunction lifted, DHS may now attempt to compile and transmit Citizenship Lists to States, though the Executive Order’s built-in qualifiers (feasibility, consistency with law) still apply.
2. USPS rulemaking may move forward. USPS had already proposed a rule on June 2, 2026, laying out new standards for ballot envelope design, exactly as the Executive Order directs, and incorporating the Executive Order’s mandate limiting the distribution of mail-in ballots to individuals on government-approved lists. The stay now permits that rulemaking to continue toward a final rule.
3. Election officials face uncertainty. Granting the stay risks severe disruption of the upcoming midterm elections. Even before a final rule, the Executive Order and proposed rule had already caused significant friction, including “challenging and costly” tasks of having to compile and convert voluminous data for submission to USPS, train election officials, educate voters, and change the format of mail-in ballots. States would have to scramble in the coming weeks to challenge, or attempt to comply with, the President’s new mail-in ballot regime. This, as the Justice Jackson noted in her dissent, is a “potentially impossible task” given timing.
4. Prosecution threat looms. The stay reactivates the Section 2(b) enforcement priority directive. Although the Court held States lack standing to challenge it pre-enforcement, the practical chill on state election officials remains.
5. Last-minute legal challenges are now inevitable. The Court’s ruling requires the Plaintiffs to bring their legal challenges closer in time to the upcoming elections, delaying resolution of potentially meritorious challenges and compounding the uncertainties. Voters who disproportionately rely on voting by mail, including those who are elderly or physically disabled, have uncertainty about casting their mail-in ballots without knowing the results of the ongoing litigation.

V. Particular Impact in New York

New York was one of the state plaintiffs in the suit. Practical consequences on New York and its election system include:

1. Robust mail-in voting system is directly implicated. New York substantially expanded mail-in voting in recent election cycles. Section 3’s proposed USPS rule requiring that States enroll voters on a State-specific list before USPS will transmit their ballots mandates that “the USPS shall not transmit mail-in or absentee ballots from any individual unless those individuals have been enrolled on a State-specific list.” This would require a fundamental restructuring of New York’s existing mail ballot distribution system.
2. Envelope redesign costs. Several states had already purchased mail-ballot envelopes for the 2026 elections. The States would also almost certainly have to bear other significant financial costs from having to update training materials for local election officials and their staff. New York’s State Board of Elections and county boards of elections would face these same compliance costs and operational disruptions.
3. Prosecution exposure. New York election officials, who would now potentially receive incomplete DHS Citizenship Lists, face the risk described in the federal government’s own briefing — that a State’s “refusal to consider” a Citizenship List could be “relevant evidence of an intent to violate, or to facilitate the violation of, the federal laws prohibiting non-citizen voting that the Attorney General is directed to prioritize for enforcement under Section 2(b).”
4. 17-year-old primary voters. New York, like several states, permits 17-year-olds to vote in primary elections where they will turn 18 by Election Day. Although the federal government disavowed any intention to prosecute state officials for lawfully providing ballots to 17 year olds, citing the Executive Order’s requirement that all provisions be implemented “consistent with applicable law,” this remains a source of concern.
5. Sovereign authority at stake. The Constitution expressly delegates the power to conduct federal elections to the States under Article I, § 4. State-run elections are foundational to democracy and a key part of the self-governance scheme the Constitution establishes. New York’s authority over its own election administration is directly threatened by the Executive Order’s regime, regardless of how the merits are ultimately resolved.

VI. Hodgson Russ Insights

This decision is a procedurally narrow determination that is not on the merits. The Supreme Court has not held the Executive Order to be lawful. Rather, the Court held that the states acted too soon. The battle ahead over whether the federal government has authority to regulate elections, particularly with respect to mail-in ballot voting, will continue.

The First Circuit will now rule on the merits of the District Court's summary judgment, including the constitutional and statutory questions about the President's authority, and that ruling will be the next major development. If the First Circuit rules against the federal government on the merits, the federal government may petition for certiorari, giving the Supreme Court the opportunity to resolve the underlying constitutional questions, including the scope of presidential authority over federal elections, definitively.

In the meantime, however, state election officials across the country face a period of profound uncertainty. Clients with interests in election administration, federal-state relations, or voting rights should monitor these proceedings closely and plan for rapid-response litigation if and when the USPS finalizes the rule.

To the extent the state relies on mail and absentee balloting for the 2026 general election, county boards of elections should monitor whether USPS attempts near-term enrollment or envelope-barcode compliance requests, and coordinate with legal counsel and the state Attorney General’s office on any coordinated response or renewed injunctive relief.

There is a related nationwide injunction that is unaffected by this decision. But the federal government has already asked it be lifted given the decision.

Hodgson Russ defended mail-in voting in litigation up to New York’s highest court in two successive rounds of litigation. Amedure v. State of New York, 232 A.D.3d 48 (3d Dep’t 2024), aff’d 43 N.Y.3d 116 (2024). We are monitoring the Executive Order and related litigation closely as timing is critical and this is a quickly developing landscape.
