House Bill 4327 also would be enforced using civil lawsuits. The bill could be the strictest abortion ban Oklahoma has passed.

“It is my sincere hope that, in addition to the criminal bill passed this session, this civil liability bill will provide strong, additional protection of the life of unborn children in Oklahoma,” Stearman said in a news release.

Those opposed to the bill said they are concerned that it sets conception as a threshold. They also are worried that different forms of contraceptives could be banned next.
