Jones Day mourns the loss of our partner, Jason Leif, who passed away on December 28, 2017. A part of the foundation and fabric of our Houston Office, our Firm's character arises from the professional accomplishment, leadership, and devotion of partners like Jason.

Jason Leif represents energy industry participants, focusing on pipeline and liquefied natural gas (LNG) permitting and construction, rates and tariffs, asset acquisitions and divestitures, energy-related contracting matters, and investigations and compliance.

Jason has conducted internal investigations and worked with companies responding to inquiries from regulatory agencies, such as the Federal Energy Regulatory Commission (FERC) and the Commodity Futures Trading Commission (CFTC). He has represented companies in regulatory proceedings before FERC and state regulatory agencies. Jason has tried cases before FERC administrative law judges (ALJs), including matters involving the impact imported LNG could have on natural gas-fired electric turbines and gas distribution facilities and the valuation of crude oil shipped from Alaska's North Slope through the Trans Alaska Pipeline. Representative clients in public matters include American Energy Partners, BP, CenterPoint Energy, Chevron, Enable Midstream Partners, E.ON Global Commodities, and Scana.

Before joining Jones Day, Jason worked at FERC, where he advised ALJs in litigation involving gas pipelines, oil pipelines, and electric utilities. He contributed to decisions regarding an electric utility merger, transmission tariffs, and rate design issues. Jason is immediate past president of the Energy Bar Association (EBA). He has been a member of the boards of directors of the Charitable Foundation of the EBA and the Foundation for the Energy Law Journal, past president of EBA's Houston Chapter, and was vice chair of its Natural Gas Regulation Committee. Jason is a member of the Texas Bar Association, the Houston Bar Association, and the Bar Association of the District of Columbia.
