Question juridique clé
Whether the Federal Court could review the canton’s interpretation of Tunisian criminal law and prescription rules in cassation.
Solution extraite
No. Cassation review is limited to federal law; the interpretation and application of foreign law cannot be reviewed, except insofar as the canton correctly framed and applied Swiss conflict rules such as arts. 5 and 6 CP.
Motifs extraits
Art. 269 PPF limits the remedy to violations of federal law. Foreign law issues fall outside review, so the court may only examine whether the canton correctly understood the Swiss lex mitior rules and seriously considered which law is more favorable.
