Professor Hines completed his phased retirement in 2014, but he intends to keep teaching part-time in the next few years. He is currently completing a major article, co-authored with Laura J. Hines, on the "Federal Constitutionalization of Punitive Damage Limits." This article reviews in detail how over 500 state and federal courts have implemented the new due-process-based federal "Guideposts" intended to prevent unconstitutional excessiveness in the size of punitive damage awards since these limitations were last restated and refined by the U.S. Supreme Court in State Farm Insurance Co. v. Campbell 2003.
