Article 23.
2. In addition, it shall hear cases established under Spanish criminal laws as crimes, even though they have been committed outside national territory, provided that those criminally responsible were Spanish, or foreigners who had acquired Spanish nationality subsequent to the crime and when the following requirements are fulfilled :
a) That the act is punishable in the place of enforcement, unless in virtue of an international treaty or a regulatory act of an international organisation to which Spain is signatory, this requirement is not necessary.
b) That the injured party or the Public Prosecutor file a complaint or action before the Spanish courts.
c) That the offender has not been acquitted, pardoned or sanctioned abroad or in this last case, has not completed their sentence. If they have only completed it partly it shall be taken into account as proportionally reduced.
