TALLAHASSEE — Attorneys for Florida Power & Light customers Friday went to the state Supreme Court in a long-running lawsuit that alleges the utility did not meet obligations to help prevent power outages during 2017’s Hurricane Irma. The attorneys filed a notice of taking the case to the Supreme Court after a panel of the 3rd District Court of Appeal in August refused to reconsider a decision that backed FPL’s arguments that the state Public Service Commission has authority to determine whether the utility met its obligations during the storm. The decision backing FPL, issued May 22, reversed rulings that said customers could pursue a class-action lawsuit against the utility.
