Chief Justice Mark Cady and Justice Bruce Zager emerged as “swing” votes on the Iowa Supreme Court during the latest session, according to new analysis by Ryan Koopmans at the On Brief blog. During the 2012/2013 term, the high court handed down split decisions in 30 of the 83 cases considered that were not related to attorney discipline. Two distinct “voting blocs” emerged, with Justices David Wiggins, Daryl Hecht, and Brent Appel often on one side and Justices Edward Mansfield and Thomas Waterman on the other side. Cady and Zager were usually part of the majority and only occasionally sided with the dissenters.
A similar analysis by Koopmans showed that during the Iowa Supreme Court’s 2011/2012 term, Zager was the only swing justice, never dissenting from a majority opinion. Cady typically ended up on the same side as Waterman and Mansfield.
Tables on this page show how often each of the seven Iowa Supreme Court justices agreed with each other in non-unanimous decisions during the past two years. It will be interesting to see whether these trends hold or change.
Governor Terry Branstad appointed Cady in 1998 and Mansfield, Waterman, and Zager in 2011. Governor Tom Vilsack appointed Wiggins in 2003 and Appel and Hecht in 2006. None of the justices will be up for retention in 2014. Cady, Appel, and Hecht should have little trouble being retained again in 2016, judging from the failed attempt by social conservatives to oust Wiggins in 2012.
