Nossaman LLP


Government and Administrative Law

Nossaman represents clients who are permitted, licensed, or regulated by federal, state, and local governments. Virtually all professions and many occupations are subject to licensing laws. Our air, water, communications, and transportation facilities are regulated as well. Nossaman attorneys have represented clients before virtually every regulatory or licensing agency in California and many of the comparable federal agencies. Whether assisting a client in obtaining a permit or a license, or defending a permit or license in an accusation proceeding brought by a licensing agency, we provide effective counsel.

Nossaman has the experience and expertise to advise and represent clients on substantive compliance issues involving a host of regulatory programs or statutes, often transcending several practice areas. This includes counseling regulated clients regarding existing rules, obtaining agency interpretations or guidance, as well as designing, drafting, and seeking the promulgation of regulatory changes. Nossaman's attorneys have the skill and ability on both the state and federal levels to represent clients in administrative law matters.
