Complaints against officers of the Queensland Police Service are divided into three categories: breaches of discipline, misconduct, and official misconduct. Responsibility for the satisfactory resolution of complaints against police officers is a shared process. The Criminal Justice Commission is responsible for investigating allegations of misconduct and official misconduct against police, while the Queensland Police Service is responsible for investigating and resolving complaints involving breaches of discipline. The Criminal Justice Commission and the Queensland Police Service actively encourage people to complain if they consider a police officer's conduct to be unprofessional and the conduct constitutes a breach of discipline or is criminal in nature. Complaints can be resolved in four ways: (1) no further action if the matter is minor in nature and complainant concerns can be satisfactorily explained at the time; (2) informal resolution; (3) mediation between the subject police officer and the complainant; and (4) full investigation and sanctions when complaints are substantiated. Data on complaint outcomes indicate that complainants dealt with by informal resolution are more satisfied than complainants dealt with by formal investigation. 5 references, 15 endnotes, 10 tables, and 1 figure
