Update III:  SCR 60.03  A judge shall avoid impropriety and the appearance of impropriety in all of the judge’s activities.
A.  SCR 60.03(1) states: "A judge shall respect and comply with the law and shall act at all times in a manner that promotes public confidence in the integrity and impartiality of the judiciary."

That's cited from a decision (March 22, 2004) of the Judicial Conduct Advisory Committee (OPINION 03-1) deciding that "a judge (is) required, after a contested election, to recuse himself or herself from contested matters involving a former campaign manager," for "a reasonable period of time."

Surely, Ziegler's conflicts, her pattern of conflicts, are much more serious and cause much more damage in not avoiding the "impropriety and the appearance of impropriety," promoting the public confidence in the integrity and impartiality of the judiciary. 

Update II: Hearing ended.
