MORGANTOWN, W.Va. (AP) -- Shareholders in the former Massey Energy Co. want West Virginia's Supreme Court to revive a lawsuit they filed after the Upper Big Branch mine disaster.
Lawyers for the California State Teachers' Retirement System, Amalgamated Bank and Manville Trust are asking the justices to overturn a 2011 dismissal order and send their case back to Kanawha County Circuit Court.
Oral arguments are scheduled for Wednesday in Charleston.
The lawsuit 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.
Under the settlement, Massey agreed to make safety a priority. Then the mine near Montcoal exploded in 2010, killing 29 men.
The shareholders say Massey is in contempt of the settlement.
