In a novel legal strategy, oil companies like Exxon Mobil and Chevron are citing First Amendment protections while facing lawsuits over climate misinformation. This tactic has raised eyebrows among legal experts who see a significant shift in the original intent of anti-SLAPP laws designed to protect against oppressive litigation.

Oil Companies Leverage Free Speech to Combat Climate Lawsuits
Major oil firms are invoking free speech rights to challenge climate-related lawsuits brought by states and municipalities.
As climate change lawsuits ramp up across the United States, major oil companies are employing a striking legal strategy—claiming that their First Amendment rights are being infringed upon. This unexpected twist has surfaced in several ongoing court battles, where companies such as Exxon Mobil and Chevron stand accused of misleading the public about global warming.
The lawsuits, launched by state officials including California's attorney general Rob Bonta, assert that these corporations have not only spread misinformation but also bear responsibility for the rising costs of dealing with climate change. In response, the oil companies have enlisted a legal mechanism known as “anti-SLAPP” (Strategic Lawsuit Against Public Participation) provisions, arguing that the lawsuits themselves violate their rights to free speech.
Legal experts, such as Nicole Ligon from Campbell University, highlight the problematic nature of this defense. “What we’re seeing now is a complete inversion of the original intent of these laws,” she explained. Anti-SLAPP laws were conceived to prevent powerful entities from silencing critics through the threat of expensive litigation. Now, these oil companies are flipping this narrative, claiming that critics seeking accountability are the ones infringing on their rights.
Courtrooms across the country are witnessing these contentious battles as nearly 40 such climate lawsuits have been filed against oil companies since 2017. The stakes are high, with municipalities seeking billions of dollars in damages to assist in adaptation efforts for the impacts of climate change.
Further complicating the scenario, the previous Trump administration engaged in a legal push to halt these lawsuits, even filing preemptive actions against states like Hawaii and Michigan. Despite these attempts, Hawaii has proceeded with its own suit, while Michigan remains committed to holding oil companies accountable.
As this legal saga unfolds, the implications for corporate accountability and public discourse on climate change remain uncertain. The outcome of these cases may shape not only the future of the oil industry but also the effectiveness of legal frameworks designed to confront misinformation in the context of global warming.
