U.S. abortion providers are challenging a growing number of state “trigger laws” designed to ban abortion after the Supreme Court ended constitutional abortion protections.

A handful of challenges to trigger laws adopted in 13 states come as states also face expected legal battles over certain restrictions – such as bans on abortions over six or 15 weeks – as well as outdated bans from as far back to the 19th century that were never removed from state statutes after the Roe v. Wade decision in 1973.

Since the June 24 Supreme Court ruling, judges have put trigger laws on hold in Louisiana, Kentucky and Utah, while other challenges are pending in Idaho, Oklahoma and Mississippi. More are likely, said Mary Ziegler, a Florida State University law professor who focuses on abortion.

Some of the lawsuits argue the trigger laws are too vague or violate state constitutional protections. Ziegler said the challenges in some cases may be limited to “buying time” in conservative states that have more than one type of abortion ban and where legislatures are dominated by abortion opponents.

Here are some of the states that have seen trigger laws challenges: 


What happened: A Planned Parenthood group that operates two clinics in Idaho filed a challenge to the state’s 2020 trigger law on Monday.

Idaho’s trigger law, scheduled to take effect 30 days after Roe v. Wade opinion’s issuance, bans abortion except in instances when the pregnancy puts the woman’s life at risk. Providers can face up to five years in prison. It makes exceptions for police-reported case of incest or rape, according to the Idaho Statesman.
