Where two or more offences carry the same penalty, the authorities of the place where the initial prosecution procedures were carried out have jurisdiction.
2 Where charges have already been brought in a participant canton in respect of one of the offences at the time of the procedure to establish jurisdiction in accordance with Articles 39–42, the proceedings shall be conducted separately.
