Carl Hernandez teaches constitutional litigation, fundamental lawyering skills and clinical practice courses for legislation, criminal prosecution and defense, immigration, government practice and nonprofit practice offered by the law school. His interest in government and community development comes from his public service with local legislative bodies and non-profit organizations as well as his practice as a government lawyer.

Professor Hernandez has experience representing local government agencies on a range of issues including civil rights litigation, land use planning, governmental reorganizations, public contracts and eminent domain and water law. He has also represented private clients on immigration issues including asylum, victims of crimes and trafficking, residency and investment-based visas.

He served as an assistant dean at the BYU law school for more than 10 years. He has taught civil rights, community lawyering, fundamental lawyering skills and clinical practice courses for legislation, criminal prosecution and defense, immigration, government practice and nonprofit practice.
