U.S. Chamber files amicus brief

July 11, 2022

In a lawsuit brought by local governments against energy companies for damages allegedly attributable to climate change, the U.S. Chamber filed an amicus brief urging the Supreme Court to grant review and decide (1) whether federal rather than state common law applies to the plaintiffs’ claims, and (2) whether a plaintiff may evade federal jurisdiction by pleading federal common law claims as state-law claims.

William M. Jay and Andrew Kim of Goodwin Procter LLP and the U.S. Chamber’s Litigation Center served as co-counsel for the U.S. Chamber.

The U.S. Chamber previously filed an amicus brief in this case before the Tenth Circuit.
