Binding versus Persuasive Authority. A county court in Illinois is deciding a case involving an issue that has never been addressed before in that state’s courts. The Iowa Supreme Court, however, recently decided a case involving a very similar fact pattern. Is the Illinois court obligated to follow the Iowa Supreme Court’s decision on the issue? If the United States Supreme Court had decided a similar case, would that decision be binding on the Illinois court? Explain. (See The Common Law.)
