Scope of the Criminal Code

Effect of Foreign Verdicts

Section 6

(5) If an act of a person falling under the jurisdiction of Hungarian criminal law has already been adjudicated by a foreign court, with the exception set forth in Subsection (1), the Attorney General shall decide on the institution of criminal proceedings. In such case, the time of sentence served in a foreign country or the time of detention shall be deducted from the sentence imposed by the Hungarian court.

Article 20
Ne bis in idem
1. Except as provided in this Statute, no person shall be tried before the Court with respect to conduct which formed the basis of crimes for which the person has been convicted or acquitted by the Court.
2. No person shall be tried by another court for a crime referred to in article 5 for which that person has already been convicted or acquitted by the Court.
3. No person who has been tried by another court for conduct also proscribed under article 6, 7 or 8 shall be tried by the Court with respect to the same conduct unless the proceedings in the other court:
(a) Were for the purpose of shielding the person concerned from criminal responsibility for crimes within the jurisdiction of the Court; or
(b) Otherwise were not conducted independently or impartially in accordance with the norms of due process recognized by international law and were conducted in a manner which, in the circumstances, was inconsistent with an intent to bring the person concerned to justice.
