Če na pristojnem sodišču iz prvega odstavka teče postopek zaradi zahtevka, ki temelji na enotnih pravilih, ali je sodišče v takem pravnem sporu izreklo sodbo, potem ni mogoče vložiti nove tožbe zaradi iste zadeve med istimi strankami, razen če sklepa sodišča, pri katerem je bila vložena prva tožba, ni mogoče izvesti v državi, v kateri se vlaga nova tožba.
2 Where an action based on these Uniform Rules is pending before a court or tribunal competent pursuant to paragraph 1, or where in such litigation a judgment has been delivered by such a court or tribunal, no new action may be brought between the same parties on the same grounds unless the judgment of the court or tribunal before which the first action was brought is not enforceable in the State in which the new action is brought.
