Is an appeal admissible against the refusal to grant suspensive effect in this debt-enforcement matter?
No. Under cantonal law, no specific appeal lies against the decision on suspensive effect, and the challenge raises a merits issue not reviewable by this remedy.
Granting or refusing suspensive effect is a matter of discretion. Such a decision is generally not appealable unless cantonal law expressly provides a remedy. Vaud law does not provide a specific appeal. The appellant's arguments concern the merits, which belong in a reform-type review rather than a nullity appeal.
