Is there any concept of international double jeopardy? I understand why we want to avoid this within the same country, but if someone commits a crime against both Country A and Country B simultaneously (one act) and they are sentenced to <i>N</i> months in prison or a $<i>Y</i> fine in Country A, I don&#x27;t immediately see any reason why Country B shouldn&#x27;t be allowed to pursue a case against them as well.
