Artikel 18

1. The Party in the territory of which the alleged offender is present shall, when it has jurisdiction in accordance with Article 14, if it does not extradite that person, be obliged, without exception whatsoever and whether or not the offence was committed in its territory, to submit the case without undue delay to its competent authorities for the purpose of prosecution, through proceedings in accordance with the laws of that Party. Those authorities shall take their decision in the same manner as in the case of any other offence of a serious nature under the law of that Party.
2. Whenever a Party is permitted under its domestic law to extradite or otherwise surrender one of its nationals only upon the condition that the person will be returned to that Party to serve the sentence imposed as a result of the trial or proceeding for which the extradition or surrender of the person was sought, and this Party and the Party seeking the extradition of the person agree with this option and other terms they may deem appropriate, such a conditional extradition or surrender shall be sufficient to discharge the obligation set forth in paragraph 1.
