Key legal question
Whether a subsidiary constitutional complaint was admissible against the TPF complaints chamber decision
Extracted holding
No. The challenged decision was not a cantonal final decision, and the proper avenue was a criminal-law appeal only if Article 79 LTF applied.
Extracted reasoning
A subsidiary constitutional complaint under Article 113 LTF is unavailable against a federal authority decision of this kind. Under Article 79 LTF, decisions of the TPF complaints chamber are generally not appealable except when they concern coercive measures.
