Aug 24 (Reuters) - The U.S. Supreme Court on Monday lifted a judicial decision blocking President Donald Trump's administration from implementing his executive order to restrict the use of mail-in ballots ahead of the November midterm elections that will decide control of Congress - though another remains.
The justices granted a Justice Department emergency request to put on hold an injunction that Boston-based U.S. Judge Indira Talwani's imposed in June preventing the Republican president from proceeding with his directive in a coalition of 23 mostly Democratic-governed states and Washington, D.C. that had sued to stop it.
The court has a 6-3 conservative majority. The three liberal justices dissented from the decision.
The Supreme Court's action leaves open the door to the states suing again in the coming months as the midterm contest approaches.
Trump's executive order, issued in March, directed the Department of Homeland Security to compile and transmit to the states a list of U.S. citizens eligible to vote in each state, and the Justice Department to prioritize investigating and prosecuting state and local election officials who issue ballots to people deemed "not eligible" to vote in federal elections.
It also required the U.S. Postal Service to deliver ballots only to voters on each state's approved mail-in ballot list. The Postal Service recently moved to implement Trump's directive.
Trump has vowed to end the use of mail-in ballots nationwide before the midterms, and has long cast doubt on the security of such ballots, although evidence of voter fraud is rare.
Republicans are seeking to retain control of Congress in the hotly contested midterms. Restricting mail-in ballots would stand to disproportionately benefit Republicans given that Democratic voters traditionally have been more likely to use mail-in ballots than Republican voters.
In June, Talwani ruled that the president lacked the authority to order changes in how states administer federal elections, noting that under the U.S. Constitution, states have the role of determining voter-eligibility requirements.The judge also noted that federal agencies lack the ability to compile accurate citizen lists for each state.
The Justice Department had said the lawsuit challenging Trump's directive was premature and that the states did not have the required legal standing at this stage to sue. The agencies have not yet taken any concrete actions that impact the states and so any harm they allege is speculative, the administration said.
The states contend that their claims are not hypothetical and that the administration's "rushed effort to change the rules of mail voting on the eve of the November midterms risks disenfranchising a substantial number of voters."
The judge rejected the administration's arguments, finding that the suit was not filed too soon and that the states had legal standing because they would face election administration disruption, compliance costs and a credible threat of criminal prosecution.
Trump's executive order is part of his wider efforts to make fundamental changes in U.S. elections. Trump, who has made false claims of widespread fraud in U.S. elections including his 2020 loss to Democrat Joe Biden, has pressed the Republican-controlled Congress to pass a contentious package of voting restrictions called the SAVE America Act.
