Judges often learn private information while doing their jobs that isn't available to the public. This could include details from sealed court files, confidential records, or facts learned during court proceedings that haven't been made public.
This rule says a judge can't use that private information for personal reasons or share it with others unless it relates to their actual judicial work. For example, a judge can't use inside information they learned from a case to help themselves financially, give an advantage to a friend, or share juicy details with people outside the court.
The point of this rule is to keep judges honest and protect people's privacy. People who go to court often have to share sensitive information, like financial records, medical details, or personal disputes. They deserve to know that judges won't misuse or leak that information for reasons that have nothing to do with running the court system fairly.
