Section 4. Applicability of The Criminal Law Outside the Territory of Latvia

(4) Foreigners who do not have a permanent residence permit for the Republic of Latvia and who have committed a criminal offence in the territory of another state, in the cases provided for in international agreements binding upon the Republic of Latvia, irrespective of the laws of the state in which the offence has been committed, shall be held liable in accordance with this Law if they have not been held criminally liable for such offence or committed to stand trial in the territory of another state.

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.
