The BIS oversight mechanisms stem from the following three key aspects:
clearly defined responsibility of senior officers
the powers of authorized departments to independently and regularly oversee certain areas
the decentralization of intelligence activities performed by several independent entities - decentralization applying also to the evaluation and archiving of information and data prevents potential misuse of tools available to the Service
Oversight focuses on the legitimacy of intelligence activities, on the observation of internal regulations, on the allocation of funds and on the use of material and technological tools the Service has at its disposal.
Internal oversight mechanisms are a dynamic system adjusted to internal and external conditions. Oversight aims not only to identify mistakes and shortcomings, but also to prevent them.
The Inspection Department reporting directly to the BIS Director monitors various activities of the Service. It focuses mainly on detecting and investigating misdemeanors and criminal offences committed by BIS officers. In doing so the Inspection Department has the powers of a police body.
Department of Internal Security
Oversight activities of the Department of Internal Security focus on protecting the Service against activities and phenomena potentially threatening its internal security.
Internal Audit Group
The Internal Audit Group is an independent department reporting directly to the BIS Director.
The powers and responsibilities of the Internal Audit Group are provided for in the Rules on the Organization of the BIS and in an internal regulation. Furthermore, they are governed by Act No. 320/2001 Coll., on Financial Control in Public Administration, and its implementing regulation No. 416/2004 Coll. Internal financial oversight is to a certain extent carried out by expert monitoring units of the BIS.
