@Inna22 From the article I linked:
Using the same model Texas used in an abortion law known as S.B. 8, Missouri state Rep. Mary Elizabeth Coleman (R) introduced a proposal in December to allow private citizens to sue anyone who performs an abortion or helps a pregnant person obtain one, even if the procedure takes place outside Missouri.
S.B. 8 bans abortions after six weeks of pregnancy, which abortion advocates have argued violates the Supreme Court’s rulings on abortion, but no court has been able to stop it because it’s enforced by private parties through civil litigation, not government officials.
Coleman’s proposal didn’t get a vote in the House this year, but that doesn’t mean lawmakers in Missouri and in other Republican-led states won’t consider it in the future. An attorney involved in abortion litigation, who requested anonymity for personal safety reasons, said the only way to control abortion travel may be to enact a law like the one Coleman proposed.
“That’s the only plausible strategy I can see for anti-abortion lawmakers if they want to stop abortion tourism,” the attorney said.
“If they just say it’s illegal to leave the state to get an abortion, someone can sue and challenge the constitutionality of the statute. If they do it the way Mary Elizabeth Coleman drafted it, by this sort of private civil enforcement, it can’t be challenged in court pre-enforcement.”
If you really want to read something that will make you want to break stuff, SB 8 (TX) will do the trick.
