ATLANTA — The Georgia Supreme Court has rejected an appeal by some Republicans after a lower court judge said new controversial rules made by the State Election Board were “illegal, unconstitutional and void.”

The Republican National Committee and the Georgia Republican Party appealed a ruling from Fulton County Superior Court Judge Thomas Cox, who ruled last week that the State Election Board did not have the authority to pass the rules and ordered it to immediately inform all state and local election officials that the rules are void and not to be followed.

The rules that Cox invalidated include three that had gotten a lot of attention — one that requires that the number of ballots be hand-counted after the close of polls and two that had to do with the certification of election results.

The initial ruling came in a lawsuit filed by Eternal Vigilance Action, an organization founded and led by former state Rep. Scot Turner, a Republican. The suit argued that the State Election Board overstepped its authority in adopting the rules.

The initial ruling was hailed as a victory by Democrats and voting rights groups, who say rules the State Election Board has passed in recent months could be used by allies of Donald Trump to cast doubt on results if the former president loses the presidential election to Democratic Vice President Kamala Harris. Recent appointments to the five-member board have put three Trump-endorsed Republicans in the majority. They have passed new rules over the objections of the board’s lone Democrat and the nonpartisan chair.

County election officials from around the state — the people who run the elections — had voiced concerns over the flood of new rules taking effect so close to Election Day.

The other rules Cox said are illegal and unconstitutional are ones that: require someone delivering an absentee ballot in person to provide a signature and photo ID; demand video surveillance and recording of ballot drop boxes after polls close during early voting; expand the mandatory designated areas where partisan poll watchers can stand at tabulation centers; and require daily public updates of the number of votes cast during early voting.

One rule that the judge overturned required that three separate poll workers count the number of Election Day ballots by hand to make sure the number of paper ballots matches the electronic tallies on scanners, check-in computers and voting machines.

Tuesday’s decision was unanimous with all judges concurring.
