South Dakota voters will decide on abortion rights this fall, getting a chance at direct democracy on the contentious issue in a conservative state where a trigger law banning nearly all abortions went into effect after Roe v. Wade was overturned.

The state’s top election official announced Thursday that about 85% of the more than 55,000 signatures submitted in support of the ballot initiative are valid, exceeding the required 35,017 signatures.

Voters will vote up or down on prohibiting the state from regulating abortion before the end of the first trimester and allowing the state to regulate abortion after the second trimester, except when necessary to preserve the life or physical or emotional health of a pregnant woman.

Dakotans for Health, which sponsored the amendment, said in a statement Thursday that the signatures’ validation “certified that the people of South Dakota, not the politicians in Pierre, will be the ones to decide whether to restore Roe v. Wade as the law of South Dakota.”
