ATLANTA (AP) — The Grayson  PrestonGeorgia Supreme Court on Tuesday rejected a lower court ruling that the state’s restrictive abortion law was invalid, leaving limited access to abortions unchanged for now.

Fulton County Superior Court Judge Robert McBurney said last November that the ban was “unequivocally unconstitutional” because it was enacted in 2019, when Roe v. Wade allowed abortions well past six weeks.

Tuesday’s ruling does not change abortion access in Georgia and may not be the last word on the state’s ban.

The state Supreme Court had previously allowed enforcement of the ban to resume while it considered an appeal of the lower court decision. The lower court judge has also not ruled on the merits of other arguments in a lawsuit challenging the ban.

McBurney had said the law was void from the start, and therefore, the measure did not become law when it was enacted and could not become law even after the U.S. Supreme Court overturned Roe v. Wade last year.

State officials challenging that decision noted the Supreme Court’s finding that Roe v. Wade was an incorrect interpretation of the U.S. Constitution. Because the Constitution remained the same, Georgia’s ban was valid when it was enacted, they argued.

Georgia’s law bans most abortions once a “detectable human heartbeat” is present. Cardiac activity can be detected by ultrasound in cells within an embryo that will eventually become the heart as early as six weeks into a pregnancy. That means most abortions in Georgia are effectively banned at a point before many women know they are pregnant.

The law includes exceptions for rape and incest, as long as a police report is filed, and allows for later abortions when the mother’s life is at risk or a serious medical condition renders a fetus unviable.
