Artikel 30

1. Any Contracting State which, before the institution or in the course of proceedings for an offence which it considers to be neither of a political nature nor a purely military one, is aware of proceedings pending in another Contracting State against the same person in respect of the same offence shall consider whether it can either waive or suspend its own proceedings, or transfer them to the other State.
2. If it deems it advisable in the circumstances not to waive or suspend its own proceedings it shall so notify the other State in good time and in any event before judgment is given on the merits.
