Brian Heslin’s varied and considerable experiences in civil, criminal and administrative courtrooms have evolved into a practice dedicated to representing clients operating within the expanding Energy sector.

A significant portion of Heslin's practice focuses on the representation of companies and public utilities in the natural gas and other regulated energy industries. Over the past decade, he has developed a thorough understanding of the nuances and intricacies of these regulatory environments, including rate-making and design, natural gas procurement, energy transactions, pipeline transportation, storage and secondary capacity markets. His representation includes regular appearances before state public service commissions and the Federal Energy Regulatory Commission. Heslin also provides FERC and CFTC Dodd-Frank compliance assistance to numerous companies attempting to navigate these enhanced regulatory environments.  Recently, Heslin also has represented companies involved in the renewable energy sector, which include solar and biogas transactions.

In addition to his experience in the energy industry, Heslin devotes his time to defending clients and corporations under investigation and indictment by state and federal authorities, conducting internal and external investigations, and representing clients in civil matters including allegations of fraud, embezzlement and other civil causes of action. He leverages his experience as a prosecutor, defense appellate attorney and civil trial attorney to provide his clients with comprehensive counsel in complex and high-exposure situations. He has defended clients and negotiated significant outcomes with regulatory and enforcement agencies such as FERC, CFTC, U.S. Department of Justice, various state and federal prosecutors' offices, and other federal and state agencies.

The two segments of Heslin’s practice often intersect. Unlike regulatory counsel with minimal litigation experience or litigators with no applicable regulatory expertise, Heslin brings his skills and expertise to tackle his clients’ most serious problems.  For example, he represents energy companies involved in formal and informal investigations by regulatory agencies. In addition to representing energy clients in regulatory dockets and proceedings, he serves those same clients as litigation counsel, employing his comprehensive knowledge of those companies to pursue successful dispositions and outcomes in state and federal courts. The knowledge, temperament and skills developed in each arena equip him with a well-rounded and assured ability to obtain excellent results for his individual and corporate clients.

Heslin is a prolific writer and speaker about the rapidly changing energy sector, particularly on topics including the growing interdependency between natural gas and electric power generation, hydraulic fracturing and natural gas production, natural gas transportation and flow reversals, LNG exports and other industry trends.  To see more of his writing, please visit the MVA Energy Blog.

Prior to joining Moore & Van Allen, Heslin was a trial attorney with the United States Department of Justice, defending departmental and regulatory federal agencies in various civil matters. In addition, he served as a prosecutor and defense attorney in the United States Army Judge Advocate General’s Corps.

Heslin tried a fully contested jury trial in the federal district court of the District of Columbia.  Heslin and his trial team defended an individual charged with conspiracy to commit major fraud upon the U.S., as well as charges of wire fraud and major fraud.  Heslin's client, a 22-year veteran of U.S. Army Special Forces, served as an operations manager of a private security company that provided security services to civilian engineers in Afghanistan under USAID's infrastructure rebuilding efforts from 2003 and 2007.  The case was prosecuted by the Procurement Fraud Section of the United States Department of Justice and the U.S. Attorney's Office for the District of Columbia with support of the FBI and USAID Office of Inspector General.  After two days of deliberation, the jury remained locked at 10-2 in favor of not guilty and the judge declared a mistrial. Shortly thereafter, the prosecutors voluntarily dismissed all charges with prejudice.
