Alabama Gov. Kay Ivey (R) approved a near-total abortion ban on Wednesday aimed at the United States Supreme Court and designed to overturn Roe v. Wade , the landmark 1973 decision establishing a womans right to an abortion under the U.S. Constitution.

Roe v. Wade makes it clear that women have a right to abortion guaranteed by the 14th Amendment, but the Alabama measure almost universally prohibits abortions. Doctors who perform an abortion are to be subject to at least 10 and as many as 99 years in prison. The only exception in the legislation is if a pregnancy puts a womans life at risk.

The law is set to become effective in six months .

The legislation comes after Brett Kavanaughs appointment to the Supreme Court last year emboldened anti-abortion activists who believe the conservative jurist may finally provide a fifth vote on the court to overturn Roe. Several other states have recently moved to outlaw abortion around six weeks into a pregnancy, leaving women with little time to know they are pregnant, let alone decide to get an abortion.

The American Civil Liberties Union and other groups will quickly challenge the law, said Alexa Kolbi-Molinas, staff attorney for the ACLU Reproductive Freedom Project.
