The affidavit shall clearly state the facts and reasons for the belief that bias or prejudice exists, being definite and specific as to time, place, persons and circumstances of extra-judicial conduct or statements that demonstrate either bias in favor of any adverse party, or prejudice toward the moving party in particular, or a systematic pattern of prejudicial conduct toward persons similarly situated to the moving party that would influence the judge and impede or prevent impartiality in that action. Allegations consisting of bare conclusions and opinions shall not be legally sufficient to support the motion or warrant further proceedings.
