A coalition of groups in opposition to the state's tighter abortion law have filed a motion to block it from taking effect.

The American Civil Liberties Union of Georgia, Planned Parenthood and the Center for Reproductive Rights requested a preliminary injunction Tuesday in federal court. 

In the 27-page filing, the groups argue that HB 481, the "Living Infants Fairness and Equality Act," should not take effect while a June 28 lawsuit challenging the measure's constitutionality is decided.

The new law would prevent abortions in the state, with a few exceptions, once cardiac activity is detected, which is usually around six weeks into pregnancy. The LIFE Act also seeks to redefine "natural person" at the beginning of the Georgia state code to include an "unborn child," which is "a member of the species Homo sapiens at any stage of development who is carried in the womb."

In the larger lawsuit, SisterSong v. Kemp, the plaintiffs argue that the LIFE Act is unconsitutional because it "criminalizes pre-viability abortions in direct conflict with Roe v. Wade," which establishes a woman's right to an abortion until about 24 weeks into pregnancy.

The plaintiffs also say that the personhood language added into the Georgia code section is vague and has already lead to confusion and conflicting interpretations from medical professionals and law enforcement officials.
