"Two former BP Plc supervisors won the dismissal on Tuesday of some of the manslaughter charges facing them over the Gulf of Mexico drilling rig explosion that killed 11 people in 2010."

"U.S. District Judge Stanwood Duval in New Orleans dismissed 11 counts of seaman's manslaughter facing Deepwater Horizon rig well site leaders Robert Kaluza and Donald Vidrine.

But the judge refused to dismiss 11 other counts of involuntary manslaughter, leaving those and a Clean Water Act violation charge to be heard at a trial starting in June."
