On June 30, 2020, the U.S. Court of Appeals for the District of Columbia Circuit (D.C. Circuit) ruled en banc 10-1 in Allegheny Defense Project v. FERC to invalidate the Federal Energy Regulatory Commission’s (FERC) common practice of issuing tolling orders to extend the time for deciding rehearing requests under the Natural Gas Act (NGA) beyond the 30-day deadline set forth in the statute. The court found that a tolling order, in which FERC “grants rehearing” for the limited purpose of affording it additional time to act on a rehearing request, does not constitute “action” upon the rehearing request as required by the NGA. The decision reversed the approximately 50-year old D.C. Circuit precedent upholding the tolling order practice as permissible. The court derided the practice as an unauthorized way for FERC to stall for time while precluding parties aggrieved by FERC orders from seeking judicial review.
