ST. PAUL, Minn. (AP) — Minnesota officials have decided against appealing a federal appellate court's decision striking down part of a 2007 energy law aiming to curb coal power generation.

The Star Tribune reports that the 8th U.S. Circuit Court of Appeals ruled in June that Minnesota's law illegally regulated out-of-state utilities by restricting electricity imports from power plants that increase greenhouse gases, such as coal generators.

Utilities in North Dakota had argued the state had overstepped its bounds.

Gov. Mark Dayton said about a week after the ruling that the state would appeal, asking for a "rehearing," which usually means a review by all 12 judges on the 8th Circuit bench. But such hearings are hard to get accepted.

The Minnesota Public Utilities Commission and the Minnesota Department of Commerce said on Monday that the state has decided against an appeal.
