Massey Ex-CEO's Conviction Upheld Over Fatal Mine Blast
The 4th U.S. Circuit Court of Appeals rejected Blankenship's argument that his conviction should be overturned because the trial judge made several errors, and because prosecutors did not properly allege the specific mine safety regulations he allegedly conspired to violate.
Blankenship was convicted in December 2015 on a misdemeanor charge of conspiring to violate federal safety standards in connection with Massey's Upper Big Branch mine, site of the April 5, 2010 explosion. He was acquitted on related felony charges.
