Key legal question
When does the 30-day period under Art. 274f(1) OR begin after a conciliation authority finds no settlement?
Extracted holding
The period begins only upon the formal establishment of the failed settlement, not merely when the conciliation hearing ends; the form of that establishment is governed by cantonal procedure.
Extracted reasoning
The federal rule is unclear on the starting point. A mere factual failure of negotiations is insufficient because the conciliation procedure must be formally concluded by a binding decision or notice of no settlement. If the authority orally announces the decision with the required instructions, the period starts the next day; if the result is communicated only in writing, it starts the day after service.
