The new Dutch Police Act mandates that certain rules be followed in handling complaints against a police force or its officials. These rules address the formation of an independent commission, whose members can advise the mayor about the settlement of complaints; the terms in which a complaint must be settled; the registration of complaints and the way in which they are settled by the mayor; and periodic publication of the way in which complaints are settled and the action taken. In Rotterdam a complaint can be made when a citizen is not satisfied with the way in which he/she has been treated by the police. It can be made verbally at any police office or in writing to the mayor, the public prosecutor, or the force manager for the regional chief of police. The complaint will then be forwarded to the chief for the district involved. If a complaint is made verbally, it will be heard by a high-ranking officer, who attempts to resolve the problem immediately. The officer may have a meeting with the police officers concerned. If this satisfies the complainant, both the complaint and the result are recorded in writing and confirmed by letter within 2 weeks. If the problems remain in the relationship, the complaint is recorded in an official report and dealt with in the same way as a written complaint. A written complaint is investigated by the chief. Within a week, the complainant will be invited to a meeting with a high-ranking officer, as well as the officers implicated in the complaint. The chief renders his judgment in the matter, and a letter is subsequently sent to the complainant, confirming the content of the meeting and the judgment. If the complainant is not satisfied with the handling of the complaint, there are several avenues of appeal.
