In resolving scheduling conflicts the following priorities should ordinarily prevail:
(a) appellate cases should prevail over trial cases;
(b) criminal felony trials should prevail over civil trials;
(c) cases in which the trial date has been first set (by published calendar, order or notice) should take precedence over cases which were set later;
(d) trials should prevail over hearings, and hearings should prevail over conferences; and,
(e) trials and hearings of a judge in travel status should prevail over trials and hearings of a judge sitting in residence.
