About jurisdiction:
Art?culo 4.- Jurisdicci?n. Quedan sometidos a la jurisdicci?n dominicana:
3) Los actos de interferencia il?cita ejecutados o cualquier violaci?n a los tratados y convenios internacionales ratificados por el Estado dominicano, leyes, reglamentos y programas que regulen la seguridad de la aviaci?n civil, cometidos a bordo de aeronaves extranjeras que vuelen sobre territorio dominicano o se encuentren estacionadas en ?l, cuando tales actos o faltas interesen o incidan en la seguridad o el orden p?blico de la Rep?blica Dominicana o cuando se produzcan o se pretenda que tengan efecto en el territorio nacional.
4) Cuando se trate de un acto de interferencia il?cita o cualquier violaci?n a los tratados y convenios internacionales ratificados por el Congreso, leyes, reglamentos y programas que regulen la seguridad de la aviaci?n civil, cometidos durante un vuelo de una aeronave extranjera, se aplicar?n las leyes dominicanas si se realiza en la Rep?blica Dominicana el primer aterrizaje posterior a la comisi?n del delito.
If the events did not occur in the Dominican airspace, then Sub Article 3 would not apply. If it was in DR airspace, there would be a jurisdiction of DR.
About subarticle 4, then OK the prosecutor could claim jurisdiction based on foreign aircraft having the first landing in the DR, "cometidos durante un vuelo de una aeronave extranjera, se aplicar?n las leyes dominicanas si se realiza en la Rep?blica Dominicana el primer aterrizaje posterior a la comisi?n del delito" but if I was the defense lawayer I would argue that it's fine that if we apply this subarticle, the FOREIGN TREATIES RATIFIED BY CONGRESS BE APPLIED, so we must apply treaty bound by coungress, but the current biding treaty is the very Tokyo convention mentioned above (though if the defense is some me-too-lawyer, he may not even know about existence of some Tokyo Convention).
Then aso we have Subarticle 5:
Art?culo 5.- Aplicaci?n del Derecho Internacional.
Los actos de interferencia il?cita y otros actos que atenten contra la seguridad de la aviaci?n civil, que involucren aeronaves de Estado, de Estados extranjeros, quedan sometidos a las normas aplicables del derecho internacional.
Again...this would be leaning towards Tokyo Convention.
So all will be depending now on whether the acts were committed in/over the Dominican airspace and whether his lawyer is decent and makes use of the Tokyo Convention... then, He walks...
And about DR airspace... the incident would need have to take place less than 30 minutes before landing for this to be in the DR airspace .. I do not know how far the country's airspace extends, but I assume it is not farther than 400 kms from the borders of DR's landmass (which would be the last 30 minutes of flight, more or less).
Also the articles of the law state that the captain must make a written statement to CESAC along with witnesses, for him not to be required to testify at trial. Has he done that? We do not know. Possibility is, he has, or he has not. 50/50 chance. If he had not, he would need to show up at trial (good luck at that, that's how traffic tickets get shot down in court in the U.S.).
In any case, with half-decent lawyer, I believe the Norwegian will walk ... My bets would be 80% thanks to lack of jurisdiction cause, 20% thanks to no statement/testimony of captain.
