Key legal question
Whether the declinatory request should transfer venue to Valais despite a prior intercantonal agreement assigning the case to Vaud.
Extracted holding
No. The prior agreement on venue was treated as definitive, and no compelling reasons justified revisiting it years later.
Extracted reasoning
The parties had already agreed on Vaud competence under the cantonal procedure. After such an agreement, a transfer is only justified by imperative reasons. The case was long advanced, the investigation was closed, and trial was imminent. The appellant relied only on general arguments about the place of commission, which could have been raised earlier and did not amount to compelling grounds.
