Question juridique clé
Whether Art. 174a CPP/VD allowing an advance fee for complaint cases violates federal law and the right to complain.
Solution extraite
The advance-fee mechanism is not incompatible in itself with federal criminal law or federal supremacy; the appellant did not show that the fee lacked a reasonable basis.
Motifs extraits
Federal substantive criminal law does not preclude cantonal procedural requirements that may halt proceedings. The appellant failed to demonstrate that the requested advance was materially unjustified or that the refusal to proceed lacked reasonable grounds.
