Review the ECtHR judgment and the national decision together under Section 363a StPO.
If an ECtHR judgment establishes a violation of the Convention or one of its Protocols, the central requirement of Section 363a(1) StPO is met. The next question is whether the violation could have adversely influenced the content of a criminal court decision.
For the review, you need the complete ECtHR judgment, the national decision identified in it and the documents from your own proceedings. The application for renewal is filed with the Supreme Court.
