Identify the original precisely and explain why the evidence purpose has ended.
Start with the receipt or confirmation listing the seized items and identify each record precisely. The key issue is whether the original is still needed for the evidence. Section 110 para. 4 StPO requires a seizure for evidentiary purposes to be lifted on request once recordings or copies fulfil that purpose, unless the original is expected to be inspected at the main hearing.
Make the request in writing and explain the practical disadvantage caused by continued retention. You may offer a replacement copy where it preserves the evidentiary purpose in full.
