Federal Supreme Court, 29.04.2026, 1C_214/2026
Facts
In July 2024, Slovenia requested that Switzerland extradite A.________, an individual being prosecuted in his home country for fraud and money laundering. He is accused of defrauding investors, resulting in total estimated losses of over 1.5 million euros.
On June 25, 2025, the Federal Office of Justice (FOJ) issued an arrest warrant for the purpose of extradition, which was served to the individual on July 9, 2025. During the proceedings, A.________ alleged that he had been the victim of an attempted poisoning in a Slovenian prison, which led the FOJ to request clarification from the Slovenian authorities.
On October 23, 2025, the FOJ authorized the extradition. At the same time, as A.________ had raised the defense of a political offense, the FOJ referred the matter to the Federal Criminal Court (FCC) for a ruling. A.________ also filed an appeal against the extradition decision with the FCC.
In a single decision dated April 8, 2026, the FCC joined the two proceedings, rejected the political offense defense, and dismissed the appeal, thereby confirming the extradition decision. A.________ then filed a public law appeal with the Federal Supreme Court, seeking to have his extradition denied.
Law
The Federal Supreme Court reiterates the admissibility requirements for a public law appeal in the field of international mutual assistance in criminal matters, as governed by Art. 84 of the Federal Supreme Court Act (FSCA).
According toArt. 84 para. 1 FSCA, such an appeal is only admissible if it involves a "particularly important case." Paragraph 2 specifies that a case is considered as such, in particular, when there are reasons to believe that fundamental procedural principles have been violated or that the proceedings abroad exhibit serious defects. The Federal Supreme Court emphasizes that this condition is intended to limit access to its jurisdiction and must be interpreted restrictively. The existence of a particularly important case is admitted only in exceptional circumstances, even in extradition matters.
In accordance withArt. 42 para. 2 FSCA, the appellant is required to substantiate their appeal by explaining how the contested decision violates the law. When admissibility depends on Art. 84 FSCA, the appellant must specifically demonstrate why their case is "particularly important."
Finally,Art. 109 FSCA allows the Federal Supreme Court to rule via simplified procedure (with three judges) and to declare an appeal inadmissible if it does not meet the requirement of a particularly important case.
Application to the specific case
The Federal Supreme Court is examining whether the appellant has sufficiently demonstrated that their case constitutes a "particularly important case" justifying a review on the merits.
The appellant maintains that the Slovenian criminal proceedings are politically motivated. To support these claims, they cite an alleged poisoning attempt, threatening letters, and attempted bribery by Slovenian state agents.
However, the Federal Supreme Court finds that the grounds for the appeal are largely insufficient.
- General grounds: The appellant merely refers to their previous submissions, which fails to meet the requirements for substantiation under Art. 42 para. 2 of the Federal Supreme Court Act (LTF).
- Poisoning attempt: The "laboratory test" provided was deemed inconclusive by the lower court because it contained neither a date nor a name. Furthermore, the appellant failed to mention that, according to Slovenian authorities, they personally refused a medical examination upon their release from prison.
- Threatening letters: The appellant provides no evidence linking these letters to Slovenian state bodies; their assertion is described as an "incomprehensible assumption."
- Corruption and threats: The allegations of attempted bribery and death threats against their family are not sufficiently substantiated.
The Federal Supreme Court concludes that neither the facts established by the Federal Criminal Court nor the appellant's insufficiently substantiated grievances provide concrete evidence of political persecution. The appellant fails to demonstrate the existence of a particularly important case within the meaning of Art. 84 LTF. Furthermore, the Federal Criminal Court correctly applied the case law regarding the political offense exception.
Outcome
The Federal Supreme Court does not enter into the merits of the appeal, deeming it inadmissible.
The appellant's request for free legal aid is also rejected. On one hand, they failed to provide the necessary documents to prove their indigence. On the other hand, their appeal was devoid of any chance of success from the outset due to its inadequate substantiation and unsubstantiated allegations.
Consequently, the court costs, set at 2,000 francs, are charged to the appellant.
