Matthew Field


Matt Field, a partner in the Regulatory Group, applies his expertise in administrative law to assist clients with regulatory and legislative matters in a broad range of industries, with a particular focus on highly regulated network industries. Matt represents clients through all stages of the regulatory process, from compliance advice and informal contacts with regulators through defense of enforcement actions and appellate litigation.

While Matt represents clients from a broad range of industries before a variety of regulators, he has particularly extensive experience in the postal and energy industries. In the traditional energy space, he litigates cost-of-service and market power issues before the Federal Energy Regulatory Commission and in federal courts, including representing shippers in challenges to the rates and practices of oil pipelines. Matt is also active in the “new energy” space, guiding clients through evolving regulatory issues associated with renewable energy and counseling them on transactional issues related to the purchase and development of renewable energy.

In the postal industry, Matt provides regulatory and legislative advice to mailers and trade associations and represents mailers in litigation before the Postal Service, Postal Regulatory Commission, and federal courts.

Representative Clients

Matt serves as outside General Counsel to the Association for Postal Commerce. He has also represented the Alliance of Nonprofit Mailers and MPA/The Association of Magazine Media in postal matters. Additionally, Matt represents individual mailers in matters before the Postal Service and Postal Regulatory Commission, including defending against revenue deficiency claims and pursuing Negotiated Service Agreements.

In his energy practice, Matt represents shippers on oil pipelines, including refiners, producers, and end-use consumers, in rate litigation and regulatory proceedings before the Federal Energy Regulatory Commission. He has also represented industrial energy consumers in negotiations with suppliers of natural gas, electricity, and petroleum products and in the development of renewable energy projects.
