XII. Ando, an Indonesian national who just visited the Philippines, purchased a ticket for a passenger vessel bound for Hong Kong. While on board the vessel, he saw his mortal enemy Iason, also an Indonesian national, seated at the back portion of the cabin and who was busy reading a newspaper. Ando stealthily approached Iason and when he was near him, Ando stabbed and killed Iason. The vessel is registered in Malaysia. The killing happened just a few moments after the vessel left the port of Manila. Operatives from the PNP Maritime Command arrested Ando. Presented for the killing of Iason, Ando contended that he did not incur criminal liability because both he and the victim were Indonesians. He likewise argued that he could not be prosecuted in Manila because the vessel is a Malaysian-registered ship. Discuss the merits of Ando's contentions. (4%)
