Atlanta, Georgia - The Georgia Supreme Court on Monday reinstated a law in the state prohibiting abortions for women who are more than six weeks pregnant, one week after it was struck down by a lower court.

Fulton County Superior Court Judge Robert McBurney ruled last week that Georgia's so-called "heartbeat" abortion law is unconstitutional.

Georgia Attorney General Chris Carr, a Republican, appealed the ruling and the Georgia Supreme Court on Monday put it on hold while the appeal is being heard.

Georgia's law bans abortions after an embryo's cardiac activity can be detected, which is usually around six weeks, before many women even know they are pregnant.

It was passed by the Republican-dominated state legislature in 2019 and went into effect in 2022 after the US Supreme Court struck down the nationwide right to the procedure.

The Supreme Court's abortion ruling unleashed a wave of restrictions in nearly two dozen of the 50 US states, and abortion rights have become a key issue in the November presidential election between Republican Donald Trump and Democrat Kamala Harris.

McBurney's ruling would have once again allowed abortions in Georgia up until fetal viability, which is around 22 weeks of pregnancy.

"Liberty in Georgia includes... the power of a woman to control her own body, to decide what happens to it and in it, and to reject state interference with her healthcare choices," the judge said.

"That power is not, however, unlimited," he added. "When a fetus growing inside a woman reaches viability, when society can assume care and responsibility for that separate life, then – and only then – may society intervene."

Monica Simpson, executive director of the group which brought the case challenging the six-week abortion ban, the SisterSong Women of Color Reproductive Justice Collective, denounced the Georgia Supreme Court's decision as "unconscionable."

"Every minute this harmful six-week abortion ban is in place, Georgians suffer," Simpson said in a statement. "Denying our community members the lifesaving care they deserve jeopardizes their lives, safety, and health – all for the sake of power and control over our bodies."
