It's hard to see how suing one of your best customers in hopes they'll buy more from you is a smart business decision.
But that's the dubious strategy pursued by North Dakota and its coal industry in filing a federal lawsuit against the state of Minnesota -- one of North Dakota's most cost-effective markets for coal-fired electricity.
This flawed lawsuit seeks to overturn key provisions of Minnesota's historic 2007 Next Generation Energy Act, keeping the state mired in the fossil-fuel past instead of moving toward a future powered by clean, renewable energy.
The lawsuit, filed Nov. 2 by North Dakota Attorney General Wayne Stenehjem, alleges that the Minnesota law's restrictions on coal-fired electricity discriminate against North Dakota companies, violating the U.S. Constitution's interstate commerce clause.
Two coal companies, a North Dakota coal trade group and three utility companies joined Stenehjem in filing the suit.
The lawsuit is unlikely to succeed and is a waste of taxpayer dollars.
The weakness of the its principal discrimination argument, along with the other out-there reasoning included in it, reveals this legal maneuver for what it really is: a Hail Mary-effort by Big Coal to hang onto the big energy market next door.
Minnesota's groundbreaking law, signed by then-Gov. Tim Pawlenty, a Republican, put in place some of the nation's most aggressive renewable-energy standards.
