ExxonMobil is attempting to use an unusual Texas law to target and intimidate its critics, claiming that lawsuits against the company over its long history of downplaying and denying the climate crisis violate the US constitution’s guarantees of free speech.

The US’s largest oil firm is asking the Texas supreme court to allow it to use the law, known as rule 202, to pursue legal action against more than a dozen California municipal officials. Exxon claims that in filing lawsuits against the company over its role in the climate crisis, the officials are orchestrating a conspiracy against the firm’s first amendment rights.
