Solicitor

Acting Deputy Solicitor General Cordelia Halberstam-Brock has spent eleven years building an uncompromising legal career in the Robert F. Kennedy Department of Justice Building. When the Solicitor General assigns her lead counsel on the Vandermeer Industries cert petition, she understands immediately what is at stake: the post-Loper Bright administrative-law landscape, the survival of Skidmore deference, and the interpretive authority of the regulatory state itself. The case will require her to face opposing counsel Tobias Vandermeer-Pelletier, a doctrinally rigorous advocate she has argued against before. It will require her to work through cert stage, merits briefing, and oral argument with precision and institutional discipline. And it will require her to carry the weight of the federal government's position through a dispositive moment that will shape the regulatory landscape for the next generation. The work is exacting. The stakes are institutional. The voice that will carry them to the Supreme Court is hers.
