Complaints to the Office for Judicial Complaints (now handled by the Judicial Conduct Investigations Office) can be made on various grounds, such as inappropriate behaviour, conflict of interest, and misuse of judicial status. However, objections to judicial decisions in a case are not grounds for complaint as these should be addressed through the appeals process. 

Key Point: The complaints system is designed to address misconduct or improper behaviour by judges, while the appeals process addresses dissatisfaction with judicial decisions.
