Questão jurídica principal
Admissibility of the federal nullity appeal against a cantonal criminal-procedure decision on seizure
Decisão extraída
The nullity appeal was inadmissible because the contested decision rested on cantonal criminal procedure, not on federal substantive criminal law, and the complainants lacked standing under the applicable rules.
Fundamentação extraída
Nullity review lies only for violations of federal law in cases based on federal substantive law; here the issue concerned procedural seizure law. The complainants also did not fall within the exhaustive standing provisions.
