ExxonMobil asked a federal court on Monday to throw out a subpoena from New York state which would force the firm to handover decades of documents as part of a wide-ranging inquiry into whether it misled investors about climate change risks.
The move means Exxon has now requested the US District Court in Texas for injunctions against two major climate subpoenas, one issued by New York and the other from Massachusetts which the company challenged in June.
Exxon has claimed the current inquiries are politically motivated.
A group of state attorneys general, led by New York, said in March they would go after the world’s largest publicly traded oil company for allegedly violating securities laws by soft-pedaling the dangers of climate change and efforts to fight it.
Judge Ed Kinkeade has yet to rule on Exxon’s requests in the high-profile case.
But in a statement to the court last week, Kinkeade said he would be concerned if there was “bias or prejudgement about what the investigation of Exxon would discover” when Massachusetts Attorney General Maura Healey issued her subpoena.
