Separate warrants sought the surrender of suspects so German proceedings could address the allegations.
A county court permitted surrender on September 18, 2026.
The defense announced an appeal; the reviewed reporting did not establish that it had been filed.
A Warsaw court rejected the request in October 2025 after considering objections specific to that proceeding.
The refusal ended that surrender request before the Polish court, not every Nord Stream case.
An initial approval was overturned over a procedural classification problem.
A renewed order survived further appeal, and Serhii K. was transferred in November 2025.
What the courts decided: whether and how a requested person would enter Germany’s criminal process. What they did not decide: whether Germany’s allegations were proved.
