For organisational purposes, the National Prosecution Authority is divided into Prosecution Districts. There are five Prosecution Districts: Southern Finland, Western Finland, Northern Finland, Eastern Finland and Åland.
A Prosecution District is responsible for organising prosecution duties in criminal matters considered in its area. Additionally, Prosecution Districts
- develop the prosecution activities in their areas under the guidance of the Office of the Prosecutor General
- are responsible for the effectiveness of prosecution activities
- supervise the legality and consistency of the activities of the prosecutors
- take care of co-operation between authorities.
The Chief District Prosecutor heads a Prosecution District, assisted by Deputy Chief District Prosecutors.
