Public Policy, Regulatory & Political Law

To successfully conduct business that involves California government demands an experienced team. Many of our lawyers have held high-ranking elected and appointed government positions, providing us with an insider’s view of how laws and regulations affect business activities and transactions in the state. Members of our team have served as US secretary of commerce, US trade representative, chief counsel and deputy administrator for the US Department of Transportation’s National Highway Traffic Safety Administration, vice president of City of Los Angeles Board of Transportation Commissioners, senior advisor to a California congresswoman, deputy executive director of the Department of Airports of the City of Los Angeles and a high-ranking official in the Los Angeles City Attorney’s Office.

We are intimately familiar with the legal, political and economic considerations of conducting business with California government entities and can help clients understand and comply with these unique requirements. The result is an exceptional ability to achieve legislative, regulatory and policy outcomes that benefit our clients. 

Government Contracts

Doing business with the government can involve special challenges that require experienced counsel. At Mayer Brown, we understand the opportunities and challenges of contracting with federal, state and local government agencies. Our lawyers regularly advise clients on government contracting and procurement matters, including contract disclosures and requirements for minority- and women-owned businesses and living or prevailing wages. We also work with clients to negotiate, interpret and administer government contracts.

Our lawyers provide end-to-end advice to private clients seeking to do business with state and local governments, including assistance with the application and bid process, disclosures, concession agreements, RFQ and RFP question-and-answer periods, MBE/WBE requirements, use of subcontractors and bid protests (which are increasingly common, particularly at the local level).

Our experience representing government entities in multiple first-of-their-kind transactions and procurements enables us to fully understand the procurement process from the government’s perspective and has been a successful formula for our private clients. Our state and local procurement services span a myriad of industries. We have deep experience in addressing clients’ state and local procurement needs in relation to in construction, transportation, infrastructure, public works, information technology, financial services, telecommunications and real estate. As state and local governments adopt more stringent procurement guidelines, we help simplify and navigate the process, ensuring that our clients meet every necessary requirement while compiling competitive bids.

Our California team includes some of the most respected and experienced protest lawyers in the state, having represented clients in protests before the City and County of Los Angeles, the Los Angeles County Metropolitan Transportation Authority, Los Angeles World Airports, the Port of Los Angeles  and the City and County of San Francisco and California Public Employees' Retirement System (CalPERS), among others.

Land Use

Mayer Brown’s Land Use practice in California advises clients in an effective, cost-efficient manner with regard to the full range of legal and political issues that routinely arise in the course of entitling and developing a project. With support from lawyers from the firm’s Government Relations, Real Estate and Environmental practices, our results-oriented approach has allowed us to obtain entitlements in even the most controversial and complex development projects.

Our team is experienced in all stages of real estate and land use projects, including planning, permitting, financing and, when necessary, asserting or protecting our clients’ rights in court. Our involvement ranges from providing strategic advice on a particular legal or political issue to serving as the project manager on complicated or controversial projects. We work seamlessly with existing project teams, adapting our level of services and approach to the circumstances of each project. In addition, our lawyers leverage their relationships with premier architectural, engineering and environmental firms in order to assemble the best possible team of design professionals and consultants.

Land use issues have a public component, and Mayer Brown’s lawyers have years of experience working with governmental bodies and are therefore able to help our clients navigate changing regulatory environments. Our government experience allows us to understand the political and administrative staff-level realities that arise during the course of land use work.

We counsel numerous clients regarding health care reform developments on the national and state levels. We also represent clients in connection with alleged violations of food and drug laws and state attorneys general matters.

We have also counseled and advised Indian tribes on other gaming-related matters, including proposed federal gaming legislation and actions of the National Indian Gaming Commission, local development issues, election law advice relating to gaming interests and federal lobbying laws relative to federal gaming legislative issues.
