Questione giuridica chiave
Whether approval for secondary use of mutual legal assistance materials in the Berlin administrative proceedings was lawful
Decisione estratta
The approval was lawful because the proceedings were closely connected to the criminal case and the request clearly defined the intended use.
Motivazione estratta
Secondary use is admissible when the new proceedings are sufficiently connected to the criminal matter and the request is sufficiently precise; here the Berlin proceedings concerned a decisive preliminary question for the criminal case.
