Belarusian enforced-disappearance case reaches Swiss appeal trial

The appeal trial opened on September 22, 2026, at the Cantonal Court of St Gallen, placing one of Belarus’s darkest political episodes before a Swiss court. A 48-year-old Belarusian national stands accused of taking part in the enforced disappearance of three opposition politicians in 1999. The relatives of those men are pursuing the case as private prosecutors.

The proceedings carry significance beyond the individual defendant. Switzerland introduced enforced disappearance as a criminal offence in 2017, incorporating an obligation linked to a United Nations convention. This appeal gives the St Gallen court an opportunity to apply that provision in a case involving alleged state-backed violence abroad.

The defendant’s own account brought the allegations into the Swiss legal system. In a 2019 asylum application, he stated that he had participated in the murders of three opposition politicians on behalf of the regime led by President Alexander Lukashenko. He is alleged to have been a member of a Belarusian special forces unit. The appeal court must now assess the reliability of those statements and the evidence surrounding them.

The alleged disappearances date back 27 years, to a period when opponents of Alexander Lukashenko’s government vanished in Belarus. The source material identifies the victims as three opposition politicians, but the present proceedings focus on the defendant’s alleged role and on whether the evidence meets the requirements of Swiss criminal law.

The accusation entered the Swiss record after the defendant described his alleged involvement during an asylum process. Such statements can carry major legal weight, but they also require careful scrutiny. The Rorschach District Court found contradictions in his accounts and concluded in September 2023 that the evidence did not support a conviction.

The case therefore turns on more than the gravity of the allegations. Judges must examine what the defendant said, when he said it, whether the accounts remained consistent, and how they compare with other evidence. The relatives’ decision to appeal keeps the disappearances before the Swiss courts and ensures that the legal record will address events that Belarusian authorities have not resolved through a process accepted by the families.

The September 2023 acquittal is the appeal’s immediate legal starting point. The Rorschach District Court cleared the defendant after finding contradictory statements and a lack of evidence. The relatives of the missing politicians then lodged an appeal, taking the case to the Cantonal Court of St Gallen.

The appeal process allows the higher court to revisit the factual and legal assessment made at first instance. The judges will consider whether the lower court evaluated the defendant’s statements and the wider evidentiary record correctly. The source does not indicate when the appeal court will issue its ruling or whether additional witnesses will appear.

The proceedings have drawn close attention from media organisations and rights NGOs. Their interest reflects the case’s unusual position in Swiss justice: it concerns alleged crimes committed abroad, a Belarusian defendant, and a Swiss statutory offence that has existed for less than a decade. Any ruling will help clarify how Swiss courts approach allegations of enforced disappearance when the underlying events occurred overseas and the evidence may be decades old.
