Swiss Federal Supreme Court, 27.02.2026, 1C_117/2026
Facts
A German-Italian national, A.________, was arrested in Switzerland following an alert issued by German authorities in the Schengen Information System (SIS). Germany requested his extradition for fraud, both for the purpose of criminal prosecution and for the enforcement of a sentence.
The Federal Office of Justice (FOJ) granted the extradition. This decision was upheld by the Federal Criminal Court (FCC) following an appeal by A.________. The latter then filed a public law appeal with the Federal Supreme Court (FSC), requesting that the FCC's judgment be set aside and his extradition be denied.
Legal Analysis
The Federal Supreme Court reiterates the admissibility requirements for a public law appeal in the field of international mutual legal assistance. According toArticle 84 of the Federal Supreme Court Act (FSCA), such an appeal is only admissible if the case is of particular importance. The appellant is required to explain in their brief how this condition is met.
Furthermore, in accordance with the general requirement for substantiation underArticle 42(2) FSCA, the appellant must concisely but precisely explain how the contested decision violates the law. They cannot simply rely on appellate-style criticism or general references to case files.
Article 108 FSCA allows the Court to rule via simplified procedure on appeals that are manifestly inadmissible.
Application to the present case
The Federal Supreme Court notes that the appellant fails to explain in any way how his case is "of particular importance" within the meaning of Article 84 FSCA. This failure alone is sufficient to render the appeal inadmissible.
The Court adds that the appeal brief also fails to meet the substantiation requirements of Article 42(2) FSCA. The grievances raised by the appellant are deemed insufficiently supported:
- The assertion that a German judgment is time-barred is supported only by a blanket reference to documents, without any precise demonstration.
- The arguments regarding the revocation of a suspended sentence fail to demonstrate how the detailed reasoning of the Federal Criminal Court violates Swiss law.
- The appellant fails to establish the existence of manifest errors or contradictions in the request for mutual legal assistance.
As the inadmissibility of the appeal is manifest, the Federal Supreme Court applies the simplified procedure under Art. 108 of the Federal Supreme Court Act (LTF). The request for legal aid is also rejected, as the appellant has not demonstrated indigence.
Outcome
The Federal Supreme Court declares the appeal inadmissible. The request for legal aid is rejected, and the court costs are charged to the appellant.
