BATON ROUGE, La. (AP) — State laws governing disputes over how to handle the cleanup of environmental damage caused by drilling years ago have been reworked under a bill supported by Gov. Bobby Jindal and now headed to his desk.

Final legislative passage came Tuesday with a 27-12 Senate vote, over the objections of senators who said it was inappropriate to make the new rules retroactively apply to cover hundreds of long-running lawsuits.
