MONTGOMERY, Ala. (AP) — A federal lawsuit filed Friday asks a judge to block an Alabama law that outlaws almost all abortions, the most far-reaching attempt by a conservative state to seek new restrictions on the procedure.

The American Civil Liberties Union and Planned Parenthood filed the lawsuit on behalf of abortion providers seeking to overturn the Alabama law that would make performing an abortion at any stage of pregnancy a felony punishable by up to 99 years or life in prison for the abortion provider. The only exception would be when the woman’s health is at serious risk.

The law is set to take effect in November unless blocked by a judge.

The lawsuit notes that supporters of the law have acknowledged it is unconstitutional under current Supreme Court precedent.

Supporters of the Alabama law have said they expected a lawsuit and expected to initially lose in court, but they hope the appeal could eventually land before the U.S. Supreme Court.
