Several business groups have urged the U.S. Court of Appeals for the Eighth Circuit to vacate the U.S. Securities and Exchange Commission’s controversial climate disclosure rule, calling it “unlawful several times over.”

In an opening brief Friday, the U.S. Chamber of Commerce and similar advocacy organizations told the St. Louis-based appeals court that the challenged rule exceeds the SEC’s statutory authority, is arbitrary and capricious and violates the First Amendment right to free speech.
