Supreme Court's conservative majority clears one legal hurdle for Trump's mail-ballot crackdown, but a second injunction still holds

With November's midterm elections now ten weeks out, the Supreme Court handed the Trump administration an interim win Monday afternoon - and immediately handed the country a new round of uncertainty about how tens of millions of voters will cast their ballots.

The Supreme Court handed an initial win to the Trump administration in its effort to implement an executive order aimed at limiting who can receive mail-in ballots ahead of the 2026 midterm elections. The unsigned order was issued August 24. No oral argument. No full briefing schedule. The court moved fast because time is the whole point.

The justices, divided 6-3 along ideological lines with conservatives in the majority, lifted an injunction a Massachusetts-based judge had imposed in June that prevented key aspects of the executive order from going into effect this year in California and 22 other states that had challenged it. The court also granted a similar application filed by Alabama and 11 other states.

What the order does not do matters just as much. A separate nationwide injunction still blocks the Postal Service from implementing its new mail-ballot procedures for the November 3 elections. The legal fight is far from over.

What the executive order requires

Trump signed the executive order in March, saying it aims to protect the integrity of U.S. elections by ensuring noncitizens are not casting ballots. The directive came just months before the November midterm elections, which will determine which party controls the House and Senate.

The mechanics are sweeping. The provisions at issue in the case direct DHS to compile 'state citizenship lists' using federal databases and call for the Postal Service to deliver mail ballots cast only by individuals who are on its own verified rolls. The Department of Homeland Security would be required to send each state a list of citizens over the age of 18. States that do not hand over their voter rolls to the Postal Service would, under the order's framework, see mail ballots go undelivered.

Attorneys for the states argued that the Constitution gives states and Congress the power to run elections, and Trump's changes could lead to chaos and partisan abuse. 'The consequences of allowing such transformative changes to take effect so close to this fall's elections would be extreme,' attorneys for the states wrote. Dozens of state and local election officials weighed in, asking the justices to leave the order frozen while election preparations are already underway.

How the court got here

The case moved through the courts at an unusual pace. A federal judge blocked key pillars of the executive order restricting mail voting in June 2026. The 1st U.S. Circuit Court of Appeals upheld that order in late July, prompting the administration to ask the Supreme Court to intervene.

Then the situation got more complicated. On Aug. 11, Talwani issued a separate injunction against the order in the lawsuit brought by nonprofit groups, led by the League of Women Voters. That ruling made clear that her ban on implementing the order extended to all states, not just the 24 jurisdictions that brought the other lawsuit.

The administration's core argument to the justices was procedural, not substantive. The Trump administration appealed, arguing the judge's order was issued prematurely, before the Postal Service and other relevant agencies had finalized their plans to carry out the order's provisions. The six-justice majority agreed - on those narrow terms.

The majority said Trump's executive order itself does not require states to change how they conduct elections. Instead, it directs federal agencies to develop policies that could later impose requirements on states. Because those policies had not yet been implemented when 23 states and Washington, D.C., challenged the order, the court said the challenge was premature.

The majority also raised the clock. The majority found that the government would suffer irreparable harm if Talwani's order is not paused. Even if that ruling were eventually reversed, the majority emphasized, it 'would come too late for the 2026 midterms.'

The dissenters push back hard

Justice Sonia Sotomayor's dissent, joined by Justice Elena Kagan, went directly at what she saw as the majority's evasion. 'Today's decision does not address whether the President's attempts to interfere with states' administration of the November 2026 elections are lawful. Nor does it suggest that the Executive Branch has any constitutional or statutory authority to implement the President's directives. Instead, today's decision merely postpones adjudication of those challenges,' Sotomayor wrote.

In a separate dissent, Justice Ketanji Brown Jackson accused the majority of 'taking its eye off the ball' by focusing on a technical legal argument instead of what she views as the larger goal of the Trump administration.

One injunction down, one still standing

Despite the White House's celebration - the White House praised the court's ruling, calling the executive order's provisions 'commonsense measures' - the practical impact of Monday's order is limited for now.

A separate nationwide injunction issued Aug. 11 by U.S. District Judge Indira Talwani in Boston still blocks USPS from implementing the new procedures for the Nov. 3 elections. The administration would have to overcome that order as well.

In a court filing late Monday, the administration said it plans to ask the 1st U.S. Circuit Court of Appeals to pause that ruling if Judge Talwani does not pause or cancel the ruling by 5:30 p.m. ET on Tuesday. A dozen Republican-led states have already appealed that ruling.

The Postal Service, for its part, moved separately last week. On Friday, while the administration's request was still pending before the Supreme Court, the Postal Service issued its final rules for implementing the order, which it said it would not put into effect for this November's election unless and until the Supreme Court cleared the way.

Time is the administration's biggest constraint. Solicitor General D. John Sauer noted in a July court filing that 'implementation efforts for any USPS rule or DHS policy will need to begin well before November - indeed, as soon as early to mid-August - to be effective for the 2026 election, particularly given that absentee and mail-in voting begin (in some States) several weeks prior to Election Day.'

The political stakes

Republicans are locked in a tight battle to retain control of Congress in the midterms. Restricting mail-in ballots would stand to disproportionately benefit Republicans, given that Democratic voters have traditionally been more likely to use mail-in ballots.

Under the Constitution, states - not the president - administer elections. Congress does have the authority to pass legislation that alters election rules. Trump has repeatedly pressured Congress to pass the SAVE America Act, which would impose stricter voting rules. The bill would not end mail-in voting and faces an uphill climb in Congress.

The states and voting rights groups are likely to go back to court quickly to challenge the Postal Service and the final rules it issued last week. A parallel case involving consolidated challenges brought by nonprofit groups and Democratic Party committees is also pending in federal court in Washington, D.C.

Government reports and voting rights groups have consistently found voter fraud is rare and, when it occurs, is not widespread enough to affect election outcomes. That factual backdrop, which the majority opinion did not address directly, is expected to be central in the next round of litigation.

What to Watch

• Talwani's Aug. 11 nationwide injunction. The administration has said it will ask the 1st Circuit to pause that ruling if Judge Talwani does not act by 5:30 p.m. Tuesday. If the appeals court also declines, the administration's next stop is the Supreme Court - again.
• D.C. federal court. The parallel case involving challenges from nonprofit groups and Democratic Party committees is pending in Washington, D.C. A ruling there could either reinforce or complicate what the justices did Monday.
• USPS final rules. The Postal Service laid out how it would implement the order last week, but time is running short to impose major changes, with some states beginning to send mail ballots to voters in just a few weeks.
• SAVE America Act. Senate Republicans have increasingly signaled they may punt a vote on the SAVE America Act until after the midterms, given that multiple members have publicly announced intent to vote against it in its current form.
