Kernrechtsfrage
Whether the decision extending pre-trial detention must be served on the accused and defense counsel under § 47 StPO.
Extrahierter Entscheid
No. The Obergericht only notifies the requesting authority; service on the accused or defense counsel is not required.
Extrahierte Begründung
If investigation detention lasts more than one month, the files are sent to the Schwurgerichtskammer or Obergericht for a decision on continuation of detention. That decision is communicated only to the requesting authority; the accused and counsel can inquire about the outcome and may challenge continued detention by complaint without first requesting release.
