Washington • The Supreme Court has rejected Arizona's bid to put in place its ban on most abortions after 20 weeks of pregnancy.
The justices on Monday declined to reconsider a lower court ruling that the law violates 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.
Gov. Jan Brewer signed the ban into law in April 2012. Nine other states have enacted similar bans starting at 20 weeks or even earlier.
