Competing rulings by federal judges in Texas and Washington on Friday plunged the future of mifepristone, a key abortion drug, into uncertainty. 

A ruling by U.S. District Judge Matthew Kacsmaryk in Texas, a Trump appointee, put a halt on government approval of the drug, potentially decimating access to medication abortion nationwide. But just minutes later, a federal judge in Washington, Obama appointee U.S. District Judge Thomas O. Rice, ordered the Food and Drug Administration not to make any changes that would restrict access to the drug in 17 states and D.C. that sued to expand access to mifepristone.

The consequences of the rulings, at least in the short term, will be that access to mifepristone remains unchanged, because Kacsmaryk gave seven days for the federal government to appeal, which the Justice Department has committed to do.

The legal battle seems destined for argument before the nation’s Supreme Court Justices, an upcoming challenge that is worrying abortion rights advocates about access to a drug long hailed as safe by federal regulators.

“FDA is under one order that says you can do nothing and another that says in seven days I’m going to require you to vacate the approval of mifepristone,” said Glenn Cohen of Harvard Law School.

Kacsmaryk’s ruling in Texas means health care providers could be barred from prescribing mifepristone, even in states were abortion is legal. In-clinic, procedural abortion care will not be affected by the ruling.

A coalition led by the conservative legal advocacy organization Alliance Defending Freedom in November filed a federal lawsuit in Amarillo, Texas, arguing the drug comes with medical risks and should be pulled from the market.  Kacsmaryk in Texas sided with anti-abortion groups in the case.
