CHARLESTON, W.Va. (AP) -- The state Supreme Court has denied a bid by institutional shareholders in the former Massey Energy Co. to revive a lawsuit they filed two weeks after the Upper Big Branch mine disaster.
In an order released Friday, the justices upheld a 2011 dismissal order in a lawsuit brought by the California State Teachers' Retirement System, Amalgamated Bank and Manville Trust.
Twenty-nine men died in the 2010 explosion at the mine near Montcoal.
The lawsuit had accused Virginia-based Massey of violating a 2008 settlement agreement aimed at making its operations safer.
The shareholders originally sued Massey in 2007, saying it routinely failed to comply with worker-safety laws.
The justices affirmed a Kanawha County judge's ruling that the settlement agreement was invalidated the day Alpha Natural Resources bought Massey in June 2011.
