"CHARLESTON, W.Va. -- Six Massey Energy management personnel -- including the company's corporate safety director -- have filed suit challenging subpoenas that would force them to answer questions about the April 5 explosion that killed 29 workers at Massey's Upper Big Branch Mine.

Lawyers for Massey vice president of safety Elizabeth Chamberlin and five other mine managers allege the state Office of Miners Health, Safety and Training is wrongly using its subpoena power to help federal Mine Safety and Health Administration officials force them to appear for interviews with investigators."
