A trio of conservative states with so-called “trigger bans” on the books have moved closer to enacting a new set of abortion restrictions as a result of the circuitous domino effect that began with the Supreme Court’s decision to strike down Roe v. Wade.

In Texas, Tennessee and Idaho, the justices’ decision was not the relevant event springing the new limits to life. Rather, the landmark ruling was only the first falling domino, followed by the court’s issuance Tuesday of its formal judgment in the case, followed next by a 30-day period before the laws take effect.

The elaborate procedural circuitry has added an additional layer of complexity to the already confusing patchwork of state laws — and lawsuits — that emerged soon after the court upended the nearly 50-year constitutional right to terminate an unwanted pregnancy.  

“Right now, there’s a lot of confusion,” said David Cohen, a law professor at Drexel University. “It may all shake out in the very near future to a stable landscape of some states with bans, other states with restrictions, and other states very permissive. But, it also may continue to have lots of uncertainty.”
