Section 120 of the Criminal Cooperation in the European Union Act lays down a set of special conditions for the validity of the procedure for the taking over of the execution of a criminal sentence: such taking over may be ordered only on the initiative of the competent foreign judicial authority, and the latter’s initiative as well as a number of supporting documents should be transmitted to the Hungarian Minister of Justice to ultimately decide on such request. As the procedure for legal assistance involves the national authorities of different countries, it cannot be launched unilaterally by the decision of only one national judicial forum (by a Hungarian court in the present case).
