Planned Parenthood Great Plains (PPGP) announced Thursday that it has asked the United States Supreme Court to rule on an Arkansas law that blocks medication abortions.

Act 557, enacted in 2015, would require physicians who provide medically induced abortions to contract with another physician with admitting privileges to designated hospitals.

PPGP said that if the law is enforced "it would make Arkansas the first and only state to effectively ban medication abortion entirely."

The group pointed to another Supreme Court ruling -- Whole Woman's Health v. Hellerstedt -- which stated the state of Texas couldn't place restrictions on abortion services that put an undue burden "on a woman's right to decide to have an abortion."

"The impact in Arkansas would be even more severe -- ending access to abortion at two-thirds of providers and essentially banning medication abortion," PPGP said in their press release.

Cecile Richards, president of Planned Parenthood Federation of America, called the law "another attempt by politicians to control women's bodies and quietly ban abortion."

Legislators who passed the law say it advocates for women's health.
