Pennsylvania Public Utility Commission Enters Phase 2 of the Moratorium on Utility Shut-Offs [Alert]

David P. Zambito and Jonathan P. Nase discuss Chairman Gladys Brown Dutrieuille's modifications to the emergency order.

Jonathan has extensive experience in public utility, environmental, and administrative law. He has more than 30 years of experience practicing law in both the public and private sectors. Jonathan drafted legislation as a staff attorney for the Pennsylvania House of Representatives and then assisted in performance audits of state agencies while on the legal staff of the Legislative Budget and Finance Committee. He subsequently joined a Harrisburg-area law firm where he counseled clients on complex transactions, including mergers, acquisitions and financings. He also litigated cases, including proceedings before the Pennsylvania Public Utility Commission (PUC) and the Pennsylvania Environmental Hearing Board.

Before joining Cozen O’Connor, Jonathan returned to state service and served as deputy director (legal) of the PUC’s Office of Special Assistants, where he supervised attorneys drafting orders for the PUC. In that capacity, he worked on a wide variety of cases involving every regulated utility industry in Pennsylvania – water/wastewater, gas, electric, transportation, and telecommunications.

Since returning to private practice, Jonathan has advised large and small utilities, as well as municipalities and municipal authorities, on complex projects, transactions, and other matters. He also has advocated for clients before the PUC, the Pennsylvania Department of Health, the Pennsylvania Office of Open Records, other administrative tribunals, and the Commonwealth Court of Pennsylvania.

Jonathan earned his law degree from Duke University School of Law and his undergraduate degree from American University.
