The Application section establishes when the various Rules apply to a judge or judicial candidate.
I. APPLICABILITY OF THIS CODE
(A) The provisions of the Code apply to all full-time judges. Parts II through IV of this section identify those provisions that apply to three distinct categories of part-time judges. Canon 4 applies to judges and judicial candidates.
(B) A judge, within the meaning of this Code includes a court commissioner.
(C) A “full-time” judge, within the meaning of this Code, includes any judge of a court of record. A “full-time” judge also includes a judge of a court not of record who:
(1) serves in a court whose judicial weighted caseload measure, as approved by the Judicial Council, shows the need for at least 1.0 judges; or
(2) serves in more than one court whose total judicial weighted caseload measure, as approved by the Judicial Council, shows the need for at least 1.0 judges.
(D) Paragraphs (C)(1) and (C)(2) apply on the day of the judge’s appointment for judges appointed on or after January 1, 2013, and they apply on January 2, 2017 for judges appointed before January 1, 2013.
 The Rules in this Code have been formulated to address the ethical obligations of any person who serves a judicial function and are premised upon the supposition that a uniform system of ethical principles should apply to all those authorized to perform judicial functions.
 The determination of which category and, accordingly, which specific Rules apply to an individual judicial officer depends upon the facts of the particular judicial service.
