Morgan & Morgan, a national plaintiffs' law firm, is seeking to dismiss a lawsuit filed by Arkansas personal injury lawyer Jody Shackelford. Shackelford accuses Morgan & Morgan of engaging in unfair and deceptive advertising practices that allegedly harm his business. The law firm argues that Shackelford is barred under federal law and state ethics rules from bringing the lawsuit in U.S. court and contends that he has no private right to bring these claims. Morgan & Morgan asked a judge on Wednesday to toss the case.
