I still wish that Judge Walter Steed had sued the State. He was removed from his judgeship after many years because of his large family (see this earlier post http://fallofreynolds.blogspot.com/2011/01/higher-standard.html).
I can't read the tea leaves, but if the justices read Judge Waddoups' 2013 ruling, they have to realize that Utah is straining at something absurd. Look at it this way:
A. Utah wants a bigamy statute to remain in force to prosecute cohabiting adults who think of themselves as spouses, even though in the eyes of the law they CANNOT BE SPOUSES.
