Artikel 25

(1). Where the parties have agreed that disputes referred to in Article 23 (4) (a), (b), (c), (d), (h) and (i) shall be resolved through procedures other than those established in that Article, or agree on procedures to resolve a particular dispute that has arisen between them, such disputes shall, at the request of any of the parties to the dispute, be resolved as provided for in their agreement.
(2). The provisions of Article 25 (1) apply also to the disputes referred to in Article 23 (4) (e), (f) and (g), unless national legislation, rules or regulations prevent shippers from having this freedom of choice.
(3). Where conciliation proceedings have been initiated, such proceedings shall have precedence over remedies available under national law. If a party seeks remedies under national law in respect of a dispute to which this chapter applies without invoking the procedures provided for in this chapter, then, upon the request of a respondent to those proceedings, they shall be stayed and the dispute shall be referred to the procedures defined in this chapter by the court or other authority where the national remedies are sought.
