Final answer:
When a judge inadvertently receives ex parte communication, they must disclose the information to all involved parties and possibly recuse themselves to maintain the judicial process's integrity and impartiality.
Step-by-step explanation:
When judges receive ex parte communication, it presents a challenge to the concept of a fair and balanced judicial procedure. In a legal system that values adversarial proceedings and full disclosure, such communication goes against the requirement of impartiality and the equal representation of parties. The Judicial power of the United States demands that cases only be tried when there is a genuine controversy to resolve and that all deliberations and decisions are made with the utmost fairness and integrity to maintain public confidence in the judiciary.
Furthermore, as part of ensuring justice, the law prohibits prior restraint, securing the principle that freedom of expression must not be unconstitutionally hindered unless under the most extreme circumstances. Therefore, if a judge inadvertently receives an ex parte communication, they must disclose it to all parties involved and may have to recuse themselves from the case to uphold the integrity of the judicial process and the impartial nature of the adjudication.
