Every person, who has in his/her disposing power objects or property items that are to be seized, shall be obliged to release them, when so requested by the criminal police, or to facilitate the seizure in any other way. This also includes the submission of written documents. This obligation may be enforced, if necessary also by way of a search of person or premises (for the applicable prerequisites see answers to A.40).
If information saved on data carriers is to be seized, everybody shall grant access to the information and hand over or have produced an electronic data carrier in a generally customary data format, when so requested. Moreover, he/she shall suffer the production of a back-up copy of the information saved on the data carriers. Seizure is admissible if it appears to be necessary
1. for reasons of evidence,
2. to secure private law claims, or
3. to secure the skimming off of an enrichment, a forfeiture, a recovery or another property-law order stipulated by law.
Seizure of electronic data is also possible. After seizure a confiscation is possible for the same reasons. In case of refusal to produce documents, they can also be obtained by a search warrant.
