Question juridique clé
Whether the cantonal appeal against the refusal to proceed was inadmissible for lack of conclusions and motivation.
Solution extraite
The appeal court could clearly recognize that a cantonal appeal had been filed and what relief was sought; declaring it inadmissible was arbitrary.
Motifs extraits
Under Vaud procedure, such appeals need only be in writing and understandable. The filing expressly challenged the refusal to proceed, requested reopening of the investigation, and sought investigative measures; the lower court's contrary view was manifestly untenable.
