Earlier this month in Chevron USA Inc. v. Plaquemines Parish, the U.S. Supreme Court broadly interpreted the meaning of “relating to” in the federal officer removal statute.  In doing so, it vacated the judgment of the Fifth Circuit that held defendant had not sufficiently demonstrated that plaintiffs’ suit was “for or relating to” the acts it performed under the authority of a federal officer.  The Court looked to the ordinary meaning of “relating to” across various contexts and held that defendant had shown the instant lawsuit implicated acts “that are closely connected to the performance of its federal duties.” Read More »

On January 14, 2026, the U.S. Court of Appeals for the Fifth Circuit denied a petition for review challenging the Texas Commission on Environmental Quality’s (“TCEQ”) approval of a third extension of the construction deadline for the Texas LNG Port of Brownsville liquefied natural gas (“LNG”) terminal. The Court held that although environmental justice advocates had standing to challenge the extension, TCEQ’s executive director acted within her delegated authority and the agency’s decision was supported by substantial evidence under Texas administrative law. The ruling, South Texas Environmental Justice Network v. Texas Commission on Environmental Quality et al., Case No. 24-60580, clarifies the procedural and substantive standards governing construction-deadline extensions for New Source Review (“NSR”) permits under Texas law and reinforces agency discretion when permittees satisfy the express requirements of the applicable regulation.

Earlier this month, the U.S. District Court for the Northern District of New York denied a motion by several environmental organizations seeking to intervene in a multistate constitutional challenge to New York’s Climate Change Superfund Act (“CCSA” or the “Act”) – a landmark 2024 statute designed to recover climate adaptation costs from major fossil fuel producers. The statute (N.Y. Env’t Conservation Law §§ 76-0101, et seq.) has drawn national attention as one of the more aggressive state-level attempts to assign financial responsibility for climate impacts.  For background on the CCSA, see my Special Alert post.

On October 3, 2025 a three judge panel for the Second Circuit ruled that Exxon Mobil Corporation, BP P.L.C., Shell Oil Company, and the American Petroleum Institute (“API”) must pay New York City (“the City”)’s attorneys’ fees and costs for advancing “absurd” arguments in opposing the City’s motion to remand to state court its suit for deceptive practices connected to climate change. City of New York v. Exxon Mobil Corp., No. 24-1568-CV (2d Cir. Oct. 3, 2025). This decision demonstrates that while parties may, at times, find success in advancing arguments that have been rejected by other courts, there are risks to advancing such arguments, including the risk of sanctions.

A recent decision sheds light on the U.S. government’s cleanup obligations in land sales involving former military sites.  In Hamilton Square, LLC v. United States, No. 20-1285 (Fed. Cl. July 15, 2025), the U.S. Court of Federal Claims allowed a key environmental remediation claim to proceed while dismissing others in a suit alleging the Navy breached its obligation to remediate newly discovered petroleum and chloroform contamination at a property in Novato, California.

On June 6, 2025, the D.C. Circuit ruled in Appalachian Voices et al. v. FERC that the Federal Energy Regulatory Commission’s (FERC) approval of an extension of the construction deadline for Mountain Valley Pipeline, LLC’s (MVP) MVP Southgate Project (the “Southgate Project”) was permissible, denying environmental groups’ petitions for review. This case potentially forecasts future judicial treatment of agency action in the aftermath of the Loper Bright v. Raimondo decision, and signals how courts may treat future challenges aimed at delaying development in light of recent curtailment of the National Environmental Policy Act (NEPA). Read More »

On June 20, 2025, the Supreme Court issued it opinion in Diamond Alternative Energy v. EPA, holding fuel producers had standing—and had specifically demonstrated redressability—to challenge California-specific regulations EPA approved under the Clean Air Act.  The Court’s opinion  reversing and remanding to the D.C. Circuit left the merits of the case for another day, but acknowledged that the regulations at issue may be rescinded shortly, mooting most, if not all, of the parties’ controversy. Read More »

On May 29, 2025, the Supreme Court decided Seven County Infrastructure Coalition v. Eagle County, reversing the D.C. Circuit’s determination that the Environmental Impact Statement (“EIS”) issued by the U.S. Surface Transportation Board (the “Board”) in connection with an approximately 88-mile railroad line in northeastern Utah violated the National Environmental Policy Act (“NEPA”).  Justice Kavanaugh, writing for the Court, concluded the NEPA question presented “is not close” and the Board was “absolutely correct” in declining to evaluate “environmental effects from separate projects upstream or downstream from the project at issue” in the EIS.    Read More »

In a January 17, 2025 opinion in the cases of Montana Wildlife Federation et al. v. Deb Haaland et al. and Western Watersheds Project et al. v. Deb Haaland et al., the United States Court of Appeals for the Ninth Circuit examined a number of oil and gas leases in Idaho and Montana sold during the prior Trump administration, vacating some and overturning vacatur of others. The opinion offers insight into how a court may look to analyze improper agency action in instances where significant economic expenditure has already taken place. Read More »
