The bill is signed on Tuesday, and it is set to go into action this summer, threatening providers with prison time and making it Oklahoma’s most stringent abortion regulation.

The governor signed a measure into law-making, conducting an abortion at any stage of pregnancy a felony, making it the latest state to do so ahead of a Supreme Court ruling due this summer that might change the procedure’s trajectory.

Governor Kevin Stitt said, “I promised Oklahomans that I would sign every pro-life bill that hit my desk, and that’s what we’re doing here today.”

The measure, which is set to take effect 90 days after the legislative session finishes this summer, will punish health-care practitioners who perform abortions with up to ten years in prison and $100,000 in fines. Only if the mother’s life is in danger is an exception made.

The rule goes against Supreme Court precedent, which guarantees access to abortion until foetal viability, which experts commonly define as 24 weeks of pregnancy. Since the landmark Roe v. Wade ruling in 1973, no state has succeeded in enforcing an outright ban on abortion.

He said, “We want to make all abortions illegal in the state of Oklahoma,” and, “This needs to be a state issue.”

This summer, the Supreme Court is set to rule on a Mississippi abortion case that prohibits abortion beyond 15 weeks of pregnancy. Experts predict that the Supreme Court’s judgement in the Mississippi case will either overturn or severely undermine Roe.

The governor’s action comes as the state considers two more abortion prohibitions, one of which could pass the GOP-controlled legislature this week. The other legislation, unlike the new law, would rely on a Texas-style enforcement process, in which individuals are deputised to enforce them. They would file civil lawsuits against providers and others instead of criminal lawsuits, and they have proven tough to defeat in court.

Proponents of abortion rights have warned that Oklahoma might become the next battleground in the abortion debate.
