Question juridique clé
Whether a request to extend a court-set deadline is timely when posted on the last day but received only after expiry.
Solution extraite
Yes. Under the cantonal rules, the request was timely once handed to the Swiss Post before midnight on the last day.
Motifs extraits
The cantonal procedure act treats deadlines as met when the act is performed by midnight; written filings are timely if handed to the Swiss Post by then. No special rule excluded extension requests or cost-advance extension requests. The contrary cantonal practice lacked a statutory basis and was arbitrary.
