SAN FRANCISCO -- A federal court yesterday struck down Arizona's ban on abortions after 20 weeks of pregnancy absent a medical emergency.

The 9th U.S. Circuit Court of Appeals said the law violated a woman's constitutionally protected right to terminate a pregnancy before a fetus is able to survive outside the womb. "Viability" of a fetus is generally considered to start at 24 weeks.

Normal pregnancies run about 40 weeks.

Nine other states have enacted similar bans starting at 20 weeks or even earlier. Several of those bans had previously been placed on hold or struck down by other courts.

Judge Marsha Berzon, writing for the unanimous three-judge panel on the San Francisco-based court, said such bans before viability violate a long string of U.S. Supreme Court rulings starting with the seminal Roe v. Wade decision in 1973.

The judge wrote that "a woman has a constitutional right to choose to terminate her pregnancy before the fetus is viable." Gov. Jan Brewer signed the ban into law in April 2012 after it was approved by the Republican-led Legislature. Supporters said the law was meant to protect the mother's health and prevent fetuses from feeling pain.

U.S. District Judge James Teilborg ruled it was constitutional, partly because of those concerns, but the 9th Circuit blocked the ban from going into effect until it ruled.

"We look forward to an appeal to the United States Supreme Court," said Cathi Herrod, president of the Phoenix-based Center for Arizona Policy. The group filed a legal brief in support of the Arizona law.
