PHOENIX - A federal appeals court has granted a preliminary injunction to temporarily block the country's most stringent restrictions on the use of abortion drugs.
In the latest in a series of court fights over Arizona abortion laws, the 9th U.S. Circuit Court of Appeals granted Planned Parenthood Arizona's motion Wednesday.
The court is expected to decide whether to continue or lift the stay as early as Monday.
The prominent U.S. women's health organization filed an appeal after a federal judge in Tucson refused to stop the new rules, just hours before they were to take effect Tuesday.
The rules banned women from taking the most common abortion-inducing drug -- RU-486 -- after the seventh week of pregnancy.
Existing rules allow women to take the abortion pill through nine weeks.
