The Georgia Supreme Court unanimously rejected on Tuesday an attempt by national and state Republicans to reinstate a string of controversial election rules after a judge deemed them unconstitutional last week.

Georgia state GOP officials and the national party appealed a Georgia judge's ruling this week that nullified numerous recently reacted election rules that opponents say would upend the process.

The decision is yet another legal setback for the state election board, which sought to implement an array of changes in the weeks and months before the November vote.
