The crime of estafa was committed in Kuwait. In my opinion, there is no jurisdiction of the court committed outside the Philippines except in Article 2. The court in Kuwait has jurisdiction over the case of estafa.
Under Revised Penal Code,
Article 2. Application of its provisions. - Except as provided in the treaties and laws of preferential application, the provisions of this Code shall be enforced not only within the Philippine Archipelago, including its atmosphere, its interior waters and maritime zone, but also outside of its jurisdiction, against those who:
1. Should commit an offense while on a Philippine ship or airship
2. Should forge or counterfeit any coin or currency note of the Philippine Islands or obligations and securities issued by the Government of the Philippine Islands;
3. Should be liable for acts connected with the introduction into these islands of the obligations and securities mentioned in the presiding number;
4. While being public officers or employees, should commit an offense in the exercise of their functions; or
5. Should commit any of the crimes against national security and the law of nations, defined in Title One of Book Two of this Code.
There is no fact attending that falls in one of the items above.
