The state has agreed not to enforce a law requiring doctors to tell patients that medication abortions can be reversed until a legal challenge of the law goes to trial.

The agreement came as part of a lawsuit filed by Arizona doctors challenging the law, passed in 2015 as part of SB1318.

Enforcement of the law was already on hold until a scheduled three-day hearing beginning on Oct. 21 to determine whether the hold should last until trial.  No trial date has been set.

The agreement was filed in U.S. District Court today, but it will require the signature of Judge Steven P. Logan. The three-day hearing will be canceled if he signs and the case will proceed to trial.

The agreement comes less than two weeks before Logan had told both sides to be in court to argue whether he should order the preliminary injunction.

“I gather they decided to fight another day,” said attorney Dan Pocholda of the American Civil Liberties Union. “But it’s obviously a significant victory for the women of Arizona and a loss for the reactionary forces of the Center for Arizona Policy and others who are pushing this obviously wrongful legislation and clear First Amendment violations.”

CAP President Cathi Herrod, whose organization helped craft the law and push it through, said she defers to the decisions of the Attorney General’s Office in how best to defend the law. But Herrod disagreed with Pochoda’s view of the effect of the law on women.

“What is outrageous is the abortion industry that fights tooth and nail against giving women the information needed to make a decision about carrying through an abortion,” she said.

The abortion pill reversal method uses progesterone, a female hormone, to reverse the effects of the mifepristone, or RU-486, the first of a two-pill regime used in a medication abortion.

Doctors who opposed the law assert that the technique is unproven and the research on it doesn’t meet scientific standards. And doctors suing the state to strike the law allege it violates their First Amendment Rights because they are forced to give a state-sanctioned message on a medical procedure they don’t agree works.
