COLUMBUS, Ohio (AP) — A federal judge temporarily blocked an Ohio law banning abortions after a fetal heartbeat is detected on Wednesday, siding with abortion clinics that had argued the law would effectively end the procedure in the state.

The ruling by U.S. District Judge Michael Barrett halts the July 11 enforcement of the so-called heartbeat bill law that opponents argued would effectively ban the procedure. That’s because a fetal heartbeat can be detected as early as six weeks into pregnancy, before many women know they’re pregnant.

Ohio is among a dozen states that have considered similar legislation this year, as abortion opponents have pursued a national anti-abortion strategy to overturn the landmark Roe v. Wade decision fueled by a conservative swing on the U.S. Supreme Court.

Courts have already blocked substantially similar laws in Kentucky and Mississippi. Abortion providers also have sued in Alabama and Georgia.

However, Barrett said it is his opinion that Planned Parenthood and abortion clinics represented by the American Civil Liberties Union and other civil rights attorneys that sued to stop the law “are certain to succeed on the merits of their claim that (the bill) is unconstitutional on its face.”
