BATON ROUGE, La. - A divided Louisiana First Circuit Court of Appeal panel ruled March 14 that certification of the class action claims of East Baton Rouge residents for exposure to sulfuric acid following a February 1999 refinery release was in error in part based on the record (Henry T. Stewart III, et al. v. Rhodia Inc., et al., No. 11-434 $(consolidated$), La. App., 1st Cir.; 2012 La. App. LEXIS 346).
