The Supreme Court is hearing a case this week which could have a profound impact on the ability of citizen groups to prosecute polluters. They are reviewing a decision by a South Carolina appeals court which overturned the liability of an incinerator operator to pay penalties — and legal fees — for illegal dumping once the operator ceased dumping. Patrick Parenteau (par-EN-toe), Vermont Law School professor and former head of the school’s environmental law center, discusses the case’s implications with host Steve Curwood.
