Summary

Helsinki Court of Appeal overturned a district court ruling and returned the Eagle S cable damage case to district court. The appeal court found Finnish authorities have jurisdiction to investigate charges against the crew of the Cook Islands-registered vessel Eagle S, which damaged underwater cables with its anchor on the Finnish economic zone in the Gulf of Finland on December 25, 2024. The district court previously ruled in October 2025 that Finnish authorities lacked jurisdiction, considering the incident a maritime accident under the UN Convention on the Law of the Sea, requiring adjudication by the flag state or defendants' national courts. The appeal court disagreed, stating the incident was not a maritime accident under that convention and did not limit Finnish criminal jurisdiction. The appeal court decision can be further appealed to the Supreme Court if leave is granted.

Classification

Confidence: High

The incident involves hostile damage to underwater infrastructure by a foreign vessel in Finland's economic zone, which constitutes hybrid aggression targeting critical maritime infrastructure. The legal and jurisdictional contention highlights the hybrid warfare nature of the signal.
