WASHINGTON (AP) — The U.S. Supreme Court on Thursday left in place an agreement that allows Rhode Island residents to vote by mail in two upcoming elections without signing their ballots in the presence of two witnesses or a notary.

State officials had agreed to suspend the requirement because of the coronavirus pandemic. They have said that fulfilling the requirement results in close contact between voters and others, which could expose people to the virus.

The high court rejected an effort by the Republican National Committee and the Republican Party of Rhode Island to put the agreement on hold, noting that “no state official has expressed opposition.”

Justices Clarence Thomas, Samuel Alito and Neil Gorsuch would have put the agreement on hold.

Rhode Island allows voters to request to vote by mail for any reason, and the coronavirus has resulted in an enormous increase in mail-in voting.

Republicans argued that witness requirements deter voter fraud, though elections experts say voter fraud is rare. And they said the state is already allowing 20 days of early voting that will reduce the number of people who go to the polls on Election Day and has put in place other protections for voters and poll workers.

The case arose after Rhode Island Gov. Gina Raimondo, a Democrat, in April suspended the so-called two witness requirement for the state’s June 2 presidential primary.

In July, the American Civil Liberties Union brought a lawsuit on behalf of Common Cause Rhode Island, the League of Women Voters of Rhode Island and others in an effort to extend the suspension.

State officials ultimately agreed to keep the requirement suspended for the Sept. 8 primary and Nov. 3 general election. Republicans objected, but a judge approved the agreement.

The Supreme Court noted in its brief order Thursday that the most recent election had been held without the witness requirement: “The status quo is one in which the challenged requirement has not been in effect, given the rules used in Rhode Island’s last election, and many Rhode Island voters may well hold that belief.”

In statements, Steven Brown, the executive director of he ACLU of Rhode Island, called the court’s action “a victory for basic principles of democracy.” And John Marion, the executive director of Common Cause Rhode Island, said: “Because of this order hundreds of thousands of Rhode Island voters will be able to safely cast their ballots without risking their health.”

Republican Party officials in Rhode Island did not immediately respond to a request for comment.

Rhode Island Secretary of State Nellie Gorbea said in a statement that the state would begin mailing out the requested mail ballots on Thursday for the September primary. She called removing the witness or notary requirement a “common-sense step that will protect Rhode Islanders during this pandemic.” Races on the September ballot include seats in both houses of the General Assembly, Rhode Island’s two congressional seats and one of the state’s two Senate seats.

Aug. 18 is the last day voters can apply for a mail-in ballot for the primary. For the general election, Oct. 13 is the last day to request a mail-in ballot. In both cases, ballots have to be received by 8 p.m. on Election Day.
