Marc joined the Center in 2019 and is responsible for leading impact litigation on behalf of the Center’s clients. In November 2021, he argued Whole Woman’s Health v. Jackson in the U.S. Supreme Court. The case challenged Texas S.B. 8, which bans abortion at approximately six weeks of pregnancy and is enforced through a vigilante-style enforcement scheme of civil lawsuits seeking $10,000 or more against anyone who provides or aids and abets a prohibited abortion.
Marc was previously a Partner in the Appellate & Supreme Court practice at Morrison & Foerster LLP, where he was heavily involved in pro bono cases involving reproductive rights, LGBT rights, and other matters. While at the firm, Marc argued June Medical Services v. Gee in the Fifth Circuit on behalf of the Center’s longstanding client Hope Medical Group; that case challenged a Louisiana law designed to shut down most of the state’s clinics, and it led to a U.S. Supreme Court victory in 2020. Marc also successfully argued in the Ninth Circuit in National Abortion Federation v. Center for Medical Progress, which affirmed an injunction barring the release of videos that activists covertly recorded and leaked to smear abortion providers. And he was lead counsel for one of the parties in V.L. v. E.L., a U.S. Supreme Court decision requiring state courts to recognize second-parent adoption judgments issued to same-sex couples in other states.
In 2019, Marc was Senior Counsel for Ranking Member Dianne Feinstein on the Senate Judiciary Committee, where he led the Senator’s nominations team.
