Discussion

Red Velhouse:

As of October 13, 2026, the trial has not opened. Hamburg’s Higher Regional Court is scheduled to begin tomorrow. Sofia, what has the court decided, and what must prosecutors still prove?

Sofia Jadler:

The court admitted the indictment and found sufficient preliminary suspicion. That is a threshold decision, not a verdict. Prosecutors allege that Kuznietsov coordinated a seven-person team using the yacht Andromeda, explosives, and divers. At trial, they must prove his conduct, intent, and every element of the charges. They do not necessarily have to identify the senior person behind the alleged operation, but they must connect this defendant to the charged conduct. That allows the prosecution to pursue individual liability without first resolving the much larger question of state authorization. Kuznietsov denies involvement, and his lawyers dispute the existence of direct incriminating evidence.

Red Velhouse:

Before we discuss the alleged chain of command, Sam, why did these pipelines carry such political weight before they became evidence in a criminal case?

Sam Dewinski:

Nord Stream 1 and Nord Stream 2 embodied a long argument over whether energy trade could be separated from security and geopolitical dependence. They connected Russian supply to Germany and became symbols of Europe’s relationship with Moscow. The explosions came only months after Russia’s full-scale invasion of Ukraine. That history does not identify the saboteurs, but it explains why every later fact has been read as part of a much larger strategic story. The important discipline is to separate symbolism, possible military advantage, and proof of who authorized an attack.

Red Velhouse:

What is documented about Kuznietsov, and what remains reported rather than established?

Sofia Jadler:

The clearest public connection is to Ukraine’s armed forces. German reporting on the indictment identifies him as an officer in 2022, when the explosions occurred. Other reporting says he later left military service. Ukrainian media have also described earlier work in the Security Service of Ukraine, or SBU, including an economic-security unit, education at military and SBU-related institutions, and later energy-sector business. Those latter details are reported biography, not court findings; the dates, duties, and any continuing intelligence relationship remain unclear. None of this, by itself, proves participation or authorization.

Sam Dewinski:

Backgrounds are often turned into retrospective explanations. Military service becomes evidence of capability, intelligence work becomes evidence of access, and energy-sector contacts become evidence of motive or logistics. Those connections may matter, but a historian would ask whether they are independently documented and tied to this operation rather than merely compatible with it. A plausible biography is not a demonstrated role.

Red Velhouse:

Sofia, does military status create immunity, a combatant defense, or a superior-orders argument?

Sofia Jadler:

Not automatically. Military status may bear on capability, contacts, or knowledge, but it does not immunize someone from prosecution for alleged sabotage or war crimes. A claimed order could be relevant, but an unlawful order is not a legal eraser. The court will focus on the defendant’s contribution and mental state. The prosecution still needs an operation-specific bridge from biography to conduct.

Red Velhouse:

What does the prosecution allege about the wider operation, and what remains unresolved?

Sam Dewinski:

The reported structure—a coordinator, skipper, explosives specialist, and four divers—invites a command-history explanation. But the public record leaves several possibilities open: a state operation, state-linked individuals acting without authorization, or an independent group. Reports about a commander called “Roman,” possible links to Roman Chervinsky, and possible supervision by Valerii Zaluzhnyi are leads, not settled facts. The responsible approach is to preserve those competing versions until testimony and documents test them.

Sofia Jadler:

The strongest evidence would be operation-specific: authenticated orders, communications, money transfers, official equipment, access arranged through state institutions, participant testimony, or proof of direction and control over this mission. German reporting says prosecutors also rely on photographs, witnesses, travel and communications data, rental records, and other circumstantial material. It reports no fingerprint or DNA match for Kuznietsov on the Andromeda. That absence does not decide the case, but it makes the coherence of the circumstantial chain especially important.

Ann Tofado:

That evidentiary gap explains why Kyiv keeps two messages separate. Ukraine’s Prosecutor General’s Office rejects the suggestion that Ukrainian authorities, institutions, or officials ordered or participated in the explosions, says it found no evidence of official involvement, and says Ukraine is cooperating with German investigators. Cooperation signals that Kyiv wants the process handled through institutions. The denial limits diplomatic damage without requiring Ukraine to certify every detail of Kuznietsov’s personal history. It also leaves open the narrower possibility that individuals acted without authorization.

Red Velhouse:

The indictment includes a war-crime allegation involving civilian objects, along with explosives and destruction offenses. Why does that classification matter?

Sofia Jadler:

Because it adds legal elements. Prosecutors characterize the pipelines as civilian objects and the destruction as an unlawful attack. The defense may argue that they had military or dual-use significance. Under the distinction rule, an object is civilian unless it makes an effective contribution to military action and its destruction offers a definite military advantage. Economic importance or political symbolism alone does not make infrastructure a lawful military target. Even if the war-crime theory fails, separate explosives or destruction charges could remain.

Sam Dewinski:

A pipeline can be a commercial asset, a symbol of geopolitical dependence, and a possible strategic object at the same time. Those descriptions are not interchangeable. The wartime setting explains why the pipelines became targets in competing narratives, but it cannot answer whether this particular attack met the legal requirements for a war crime. History supplies the setting; the court must supply the finding.

Red Velhouse:

The detonations occurred in international waters, within the exclusive economic zones of Denmark and Sweden. Why can Germany hear the case, and what did the other investigations establish?

Sofia Jadler:

The German Federal Court of Justice rejected the argument that location automatically defeats German jurisdiction. German law permits prosecution of specified international-law offenses committed abroad. That resolves a jurisdictional objection, not guilt or state responsibility. Sweden closed its investigation because it concluded Swedish jurisdiction did not apply. Denmark found the explosions deliberate but insufficient grounds for a criminal case there. Neither decision determines Germany’s case. Germany has cleared one gate, not reached the finish line.

Ann Tofado:

Those separate investigations leave Germany carrying the main prosecutorial burden. Berlin must show that judicial independence applies even when the defendant is Ukrainian and Germany remains a major supporter of Ukraine. Kyiv must defend its official denial without appearing to obstruct German justice. Cooperation is useful diplomatically, but it also means Ukraine cannot control how the evidence develops. The verdict will therefore be interpreted politically well beyond the courtroom.

Red Velhouse:

A second Ukrainian suspect was arrested in Croatia in August, and a court approved extradition to Germany in September. Could that change the case?

Sofia Jadler:

It could broaden the evidence, but extradition is not proof against either suspect. A second defendant might provide corroboration, contradiction, or new procedural complications. The useful questions will be whether testimony or records connect individuals to the yacht, explosives, diving, communications, and any chain of command. The court may establish one person’s role without resolving who authorized the broader operation.

Sam Dewinski:

That distinction is often where the historical record remains most durable. A trial can clarify who did what without producing a complete political history of the operation. Infrastructure and war explain the setting, biography may explain capability, and trial evidence must establish participation. Each layer answers a different question.

Red Velhouse:

What would count as a meaningful outcome if the court resolves Kuznietsov’s role but not the broader chain of command?

Sofia Jadler:

A careful judgment could clarify German jurisdiction, treatment of critical infrastructure, and the evidence needed to distinguish participation from state responsibility. An acquittal would ordinarily mean the prosecution failed to prove the charges against him; it would not necessarily exonerate Ukraine or another state. A conviction would establish his liability under the charges proved, but would not automatically establish that Ukraine bears state responsibility. Individual criminal responsibility and state responsibility are separate legal questions.

Ann Tofado:

The political consequences would depend on what the judgment actually establishes. A conviction based on personal participation could strengthen demands for accountability while leaving the state question open. Evidence of official direction would be far more disruptive for Germany-Ukraine relations and possible compensation claims. An acquittal could be presented as vindication, but legally it would primarily show that this prosecution did not prove its case against this defendant. The temptation to turn one criminal judgment into a complete geopolitical verdict will be strong; the judgment may not support it.

Red Velhouse:

The central unresolved issue is not simply who placed the explosives, but how far the evidence can connect Serhii Kuznietsov to the operation—and whether it can establish state direction. The historical setting explains why the pipelines became powerful symbols, but symbolism cannot substitute for proof. Watch the opening hearings, evidence about his military and reported intelligence background, testimony concerning the Andromeda, the Croatian suspect’s extradition, and the competing accounts from German prosecutors, the defense, and Ukraine’s government. The trial may establish individual liability without resolving the full chain of command or Ukrainian state responsibility.
