Planned Parenthood has filed a lawsuit challenging North Carolina’s ban on abortion after 20 weeks.

Basically at issue is the state’s amendment more narrowly defining what constitutes the mother’s life being at risk:

In Roe v. Wade and related decisions, the U.S. Supreme Court has ruled that women have a right to abortion until the fetus is viable outside the womb — which often is considered to be about 24 weeks. Any ban on earlier abortions must allow exceptions to protect the life and health of the mother, according to the court rulings.

The amendment, which went into effect in January of this year, allows for abortions 20 weeks after the woman’s last menstrual period to “avert her death” or “for which a delay will create serious risk of substantial and irreversible physical impairment of a major bodily function.”

No doubt sensing the views President-elect Donald Trump’s nomination for the Supreme Court will have on abortion (though with Trump you never really know) Planned Parenthood is planning a wave of lawsuits:

The new lawsuit is part of a larger attack by abortion activists this week. Planned Parenthood, the Center for Reproductive Rights and the American Civil Liberties Union also filed lawsuits challenging abortion laws in Alaska and Missouri, NBC reports.

ACLU director Jennifer Dalvern described them as “the first wave” of lawsuits, meaning more are likely to be filed in the future.

“You need real facts, not junk science, to prove these anti-abortion laws are necessary. All of these laws fail this test,” she told the Independent.

“There certainly are states that have better, or fewer unnecessary restrictions, and do what they can to protect abortion rights. But we think it’s important to ensure women can get the care they need, including insurance. Most states don’t cover insurance in their public medicaid programme.”
