Georgia's highest court on Monday declined to stop voting in a referendum on whether a new city of Eagle's Landing should be created from part of the existing city of Stockbridge.

The General Assembly passed two acts that were signed by the governor earlier this year to create Eagle's Landing from land that is currently part of Stockbridge combined with unincorporated parts of Henry County. The proposed city's creation must be approved by local voters, but Stockbridge residents who live outside the boundaries of the proposed city won't get a say.

Opponents, including the Stockbridge mayor, say creation of a new city would take a significant amount of city's land and tax revenue and harm the Stockbridge's ability to pay municipal bond obligations.

Proponents of a new city say they want to secure better city services, increase property values and attract high-end businesses. But opponents say race is a factor. About 20 miles (30 kilometers) southeast of Atlanta, Stockbridge is predominantly black, while the city of Eagle's Landing would have a higher proportion of white residents.

Stockbridge sued the Henry County elections director and members of the county commission and asked a judge to declare that the acts setting up the referendum violated the state Constitution. The judge declined, and the city appealed to the Georgia Supreme Court, which heard arguments in the case last week.
