First link is commentary from Cato, the second link is to the Opinion of the Court.
The case name is MAYOR AND CITY COUNCIL OF BALTIMORE, Plaintiff, V. BP P.L.C., et al., Defendants.
State Judge Videtta A. Brown presided.
She ruled that the Clean Air Act gives the Federal Government sole and undisputed jurisdiction over climate issues and that the States are preempted and barred from interfering in climate policy and from handling climate claims.
She also shot down a number of Maryland State law claims which had been brought by the city in an effort by the Plaintiffs to throw ■■■■ at the wall and see what sticks. In this case, nothing.
Climate suits, in such as they should even be permitted to proceed at all, should be the exclusive domain of the Federal courts and this State Judge correctly realized this.
