During the investigation, the supervisor is authorised to enter any place, including business premises as well as vehicles and excluding houses, within the framework of a company visit. In doing so, the supervisor is only allowed to look around and not to search. In addition, the supervisor shall be authorised to demand inspection of and the making of copies of business information and documents. This competence does not only relate to paper documents, but also to digital data. Furthermore, the supervisory authorities have the power to demand (factual) information from, for example, employees of the company and to hear them. In general, the principle regarding these powers is that supervisors may exercise their powers to the extent that the exercise of these powers is related to the purpose and scope of the investigation.
During the investigation by the supervisory authority, the company has an obligation to cooperate. This means, for example, that you, as a company or its employee, may not refuse the supervisor access to company premises or vehicles or to digital data. If you, as a company, do not cooperate in what the supervisor can reasonably claim, it can lead to sanctions, including an administrative fine. When you intentionally fail to comply with the claim under a statutory regulation of a supervisor, then it may even result in a crime punishable by criminal law.
