I am not surprised by the Wisconsin Supreme Court's decision to publicly reprimand Justice Annette Ziegler for her handling of some cases involving West Bend Mutual during a time when her husband was one of the directors. One of the things that I do is serve the Court as a referee in attorney discipline cases. Although the final determination as to discipline lies with the Court, I have to make a recommendation. To do that, I often try to find analagous cases and see what discipline was ordered/
It's difficult for two reasons. First, it is hard to find one case that is exactly like another because a variety of factors are considered in determining the appropriate discipline. Second (and this is partially a function of the latter point), for any general "type" of case, you can often find significantly different discipline. This is one of the reasons that type of anectodal analysis done by the hyper-ideological Wisconsin Democracy Campaign is of little value. For cases with a harsh result, you can often find more lenient counterexamples.
But you can get a sense of things. My sense about the Ziegler case has always been that, for someone with no prior disciplinary history on a violation that did not involve dishonesty or knowing disregard of the rules (the court concluded that she should have known that she needed to recuse, not that she intentionally declined to do so) and that resulted in no harm to anyone, a reprimand was the most likely result. In fact, my guess is that, for a matter that was not as high profile as this, the reprimand would most likely have been private. That was simply not possible here.
Some people have suggested that more serious consequences are in order because the former Judge Ziegler now sits on the Wisconsin Supreme Court. But that cuts the other way as well. She was elected to a multi-member Court by voters who were aware of this issue. To remove her - even temporarily - would frustrate the will of the voters. You can just as easily argue that this sets the bar for more serious discipline somewhat higher.
