The Florida Supreme Court on Thursday unanimously rejected a petition filed by a Palm Beach County attorney alleging that top state officials have improperly tried to interfere with a November referendum on abortion rights. Adam Richardson, of Lake Worth, filed the petition Sept. 10 amid a controversy about an Agency for Health Care Administration webpage and video public-service announcement about abortion issues. While the agency contended the information presented facts, critics said it was biased against a ballot measure, known as Amendment 4, that seeks to enshrine abortion rights in the state Constitution.
