All collective labour disputes may be submitted to conciliation procedures.
Disputes which, for whatever reason, have not been submitted to a conventional conciliation procedure established either by the collective labour agreement or by a special agreement, may be referred to a national or regional conciliation commission.
When the dispute arises in connection with the establishment, revision or renewal of a branch agreement or a professional or cross-industry agreement, the Minister responsible for labour may, at the written and reasoned request of one of the parties or on his own initiative, directly initiate the mediation procedure under the conditions set out in Chapter III.
