Social media was quickly afire Monday night after an unprecedented leak showed the U.S. Supreme Court has circulated a draft opinion that would overturn two key abortion rights precedents.

The draft acquired by Politico was written by Justice Samuel Alito, and would overturn Roe v. Wade and Planned Parenthood v. Casey. The decision would cap off Mississippi’s defense of its ban on abortions after 15 weeks of pregnancy, a case that eventually morphed into a call to overturn the two landmark decisions.
