Mississippi's legal stance is “a request that the Court scuttle a half-century of precedent and invite states to ban abortion entirely,” the providers wrote.
The change in the composition of the court appears to be driving the case to overturn Roe. The court had rejected state appeals of similar laws in the past.
Of the Trump appointees, Justices Brett Kavanaugh and Amy Coney Barrett took seats previously held by Anthony Kennedy and Ruth Bader Ginsburg, justices who voted to uphold abortion rights. Kavanaugh once served as a law clerk to Kennedy.
But the makeup of the court is not sufficient to justify a dramatic change in the law, the providers wrote.
“Unless the Court is to be perceived as representing nothing more than the preferences of its current membership, it is critical that judicial protection hold firm absent the most dramatic and unexpected changes in law or fact,” the providers wrote.
A day earlier, Barrett and Justice Stephen Breyer, the leader of the court's diminished liberal wing, argued in separate appearances that it's wrong to view the court in partisan terms.
Barrett was among the conservative justices who allowed the Texas law to take effect.
The Mississippi 15-week law was enacted in 2018, but was blocked after a federal court challenge. The state’s only abortion clinic, Jackson Women’s Health Organization, remains open and offers abortions up to 16 weeks of pregnancy. About 100 abortions a year are done after the 15th week, the providers said.
More than 90% of abortions in the U.S. take place in the first 13 weeks of pregnancy, according to the Centers for Disease Control and Prevention.
The state has said its law would not affect many women, but the providers countered by saying that argument “is at odds with the recognition of constitutional rights in general. The very essence of a constitutional right is that the government cannot outright prohibit a certain subset of people, no matter how small, from exercising that right.”
The case hasn't yet been scheduled for arguments, which could take place in the late fall or early winter. A decision is not expected until June, and the outcome could be an issue in next year's state and congressional campaigns.
