Final answer:
A judge must disqualify themselves in a proceeding when their impartiality might be compromised, such as having a personal interest or relationship with one of the parties. This ensures fairness and maintains the integrity of the judicial system.
Step-by-step explanation:
A judge must disqualify himself in a proceeding in which the judge's impartiality might be compromised. This is to ensure that the judge remains unbiased and can make fair judgments.
One example of a situation where a judge may need to disqualify themselves is if they have a personal or financial interest in the outcome of the case. If a judge has a close relationship with one of the parties involved, it may also create a conflict of interest and require their disqualification.
Disqualification is important to maintain the integrity of the judicial system and ensure that all parties receive a fair trial.
