Florida Supreme Court set a new standard Thursday for out-of-court speech by attorneys and suggested that telling people an opposing party used prostitutes to get business may cross the line.

In a Broward County case that ended in a 4-3 split decision, the Supreme Court examined a lawsuit where the owner of Donovan Marine Inc. accused a competitor, Daniel Delmonico of MYD Marine Distributor Inc., of hiring prostitutes to attract new business clients.
