Statement on Maryland Supreme Court Decision on Mayor & City Council of Baltimore v. BP p.l.c.

March 30, 2026

The Maryland Supreme Court today dismissed climate lawfare suits brought by Baltimore, Annapolis, and Anne Arundel County against 26 energy companies, ruling that “cases involving regulation of interstate pollution arise under federal law” — and have for over a century. The court dismissed every theory plaintiffs advanced — public nuisance, private nuisance, trespass, and failure to warn — on both federal preemption and state law grounds. Today’s decision is the latest confirmation that global emissions policy belongs with Congress, not in state courtrooms. American families deserve affordable energy, not higher costs driven by litigation that is designed to circumvent the democratic process.
