Losing the right to determine when to have children would devastate women’s ability to advance their legal careers and achieve gender parity, more than 30 organizations of women lawyers and law students told the U.S. Supreme Court in an amicus brief in the new term’s latest abortion fight.

The organizations, in the brief by Mia Guizzetti Hayes, counsel at Willkie Farr & Gallagher, emphasize “reliance” on the abortion right as the key factor in the justices’ analysis of whether to accept Mississippi’s request that they overturn their landmark abortion rights rulings in Roe v. Wade and Planned Parenthood of Southeastern Pennsylvania v. Casey.
