Oct. 10 (UPI) -- The U.S. Supreme Court declined to hear former Massey Energy CEO Don Blankenship's appeal of a conviction stemming from a fatal 2010 mine explosion in Montcoal, W.Va.
Blankenship earlier this year wrapped up his 1-year sentence at a Bakersfield, Calif., low-security federal prison on a charge of conspiracy to violate mine safety standards. His appeal centered on the contention that a District Court judge should not have directed a jury that "reckless disregard" of federal safety standards could lead to a conviction, the Charleston Gazette-Mail reported.
