The union for police officers is rejecting suggestions a record high number of complaints about the police reflects a drop in standards.
The Independent Police Conduct Authority says the number of complaints it has received in the past year is the highest recorded in its 20-year history.
The IPCA's annual report shows there were 2073 complaints registered in the past year, with 80% of those accepted for investigation.
The most common complaints about police actions include failure to investigate incidents, poor attitude, bad language and use of force.
The Council for Civil Liberties says the figures suggest society's attitude to the police has changed for the worse and reflects a drop in standards.
However, Police Association president Greg O'Connor says the report also shows that less complaints are being upheld, which points to more frivolous complaints being made.
