The states of North Dakota and Minnesota on Wednesday took their legal battle over coal-generated electricity to a federal appeals court in St. Paul and faced tough questions from the three-judge panel.
The case pits Minnesota regulators against the state of North Dakota and its utility and coal interests over a 2007 Minnesota law restricting new power generation from coal. North Dakota successfully argued in federal district court that the law illegally regulates out-of-state utilities in violation of the U.S. Constitution's Commerce Clause.
Now, the Eighth U.S. Circuit Court of Appeals is reviewing an April district court ruling that enjoined Minnesota from enforcing key sections of the law. North Dakota interests say it hampers their ability to find buyers for power from existing coal-fired generating plants or to plan for new ones.
"We think the statute as it is enacted is unconstitutional — a violation of the Commerce Clause," said North Dakota Attorney General Wayne Stenehjem, who attended the oral arguments, although another attorney addressed the court on behalf of his state.
The Commerce Clause is meant to bar states from interfering in interstate commerce.
Stenehjem, in an interview with the Star Tribune afterward, said he wouldn't try to guess which way the court is leaning. Attorneys for both states faced questions from judges, who clearly had studied the lengthy pleadings filed by both sides and 31 outside groups as "friends of the court."
"It is always hard to tell just based on the questions that are asked where a court might be going," he added.
In a statement, Minnesota Commerce Commissioner Mike Rothman said: "I hope the federal appeals court will respect our state's decision to choose to purchase clean, renewable energy resources rather than striking down the law, with the consequence that Minnesota utilities would be allowed to import electricity from new, polluting coal-fired power plants in other states."
