A federal appeals court has ruled that a high-stakes lawsuit filed by the City of Chicago against major oil and gas companies must proceed in Cook County’s local court system, rather than in federal court. On July 15, a three-judge panel of the U.S. Seventh Circuit—comprised of judges appointed by presidents from both parties—unanimously upheld a lower court’s decision to keep the litigation in state court. The energy giants, including Chevron and BP, had argued that their past work performing fuel-related duties for the federal government should have entitled them to move the case to federal jurisdiction. However, the appellate panel ruled that any past federal contracts were too loosely connected to the city’s current claims to justify overriding state court authority, leaving the companies to face the case in a venue often described by business advocates as one of the most challenging in the country for corporate defendants.
The lawsuit, which Chicago filed in February 2024, centers on the allegation that petroleum companies spent decades knowingly spreading “disinformation” to mislead the public about the environmental impact of fossil fuels. The city claims this strategy fueled climate change, ultimately leading to local disasters like floods and droughts that have cost taxpayers significant sums. Furthermore, the city argues that these companies exacerbated social and racial inequities by targeting low-income and minority communities. By leaning on legal tactics popularized by past litigation against the tobacco and pharmaceutical industries, Chicago is seeking to hold these corporations financially liable for what they define as a widespread “public nuisance” and a fraudulent campaign to promote products known to be harmful.
For the oil and gas companies, the venue is a primary concern. Cook County significantly favors the Democratic Party and has frequently been labeled a “judicial hellhole” by business reform groups, who argue that corporate defendants struggle to receive a fair trial in the jurisdiction. With local government and private trial lawyers aligned against them, energy companies view the move to state court as a strategic setback. They contend that the lawsuit is essentially a policy-driven attempt to bypass federal regulations and force a transition away from traditional fuels through the hammer of litigation, rather than through legislative processes.
The Seventh Circuit’s decision addressed a specific legal theory—the “federal officer” status—which companies have used successfully in other parts of the country to remove cases from state courts. The energy companies cited a recent Supreme Court ruling (Chevron v. Plaquemines Parish) as evidence that their work for the government should trigger federal oversight. However, the Seventh Circuit panel, led by Judge Rebecca Taibleson, concluded that the Supreme Court’s ruling did not apply here. They reasoned that Chicago’s specific claims target the companies’ marketing and alleged deception of the general public, rather than any work the companies performed on behalf of the federal government or military. According to the court, the city’s pursuit of damages is independent of the companies’ federal duties.
The case has also drawn scrutiny for its financing and the law firms involved. The City of Chicago is represented by the San Francisco firm Sher Edling LLP, which has led similar “climate accountability” suits across the nation. Reports have noted that this firm receives significant funding from a “dark money” group backed by billionaires specifically aimed at litigating against the energy industry. Critics in Congress and beyond have questioned the ethics of a private, billionaire-funded firm using municipal lawsuits to attempt to bankrupt one of the nation’s core economic industries. These critics argue that the collaboration between local government and private interests creates a predatory legal cycle that circumvents constitutional norms.
Looking ahead, the road for these companies is narrow, though not yet closed. While the Seventh Circuit has denied their effort to move the case to federal court, the litigation is far from reaching a final verdict. Cook County Circuit Judge Allen Walker has refused to pause the proceedings, signaling that he believes the city’s consumer protection claims can move forward regardless of upcoming Supreme Court decisions on similar climate cases originating from other states like Colorado. As the legal battle unfolds, the energy industry continues to prepare for an uphill climb, while the City of Chicago and its legal partners push forward with a case that tests the boundaries of where corporate culpability ends and national environmental policy begins.
