2022 Political Law, Q14

A foreign commercial ship was spotted by the Philippine Coast Guard dumping garbage and toxic waste 20 nautical miles from Nasugbu, Batangas, the nearest coastline of the Philippines. The officers of the ship were arrested and charged in the Regional Trial Court (RTC) of Batangas for violation of environmental laws of the Philippines. The officers of the ship filed a motion to dismiss the case on the ground that Philippine courts do not have territorial jurisdiction over the case since the vessel was sailing outside the territorial sea of the Philippines when the arrest was made. Is the ground to dismiss correct? Explain briefly. (5 points)

1. Contiguous Zone Authority
Under Article 33 of the United Nations Convention on the Law of the Sea, the coastal State may exercise necessary control within its contiguous zone, extending up to twenty-four nautical miles from baselines. This control allows the coastal State to prevent and punish infringements of its customs, fiscal, immigration, or sanitary laws committed within its territory or territorial sea. Discharging garbage or toxic waste into coastal waters violates national sanitary and environmental protection laws, authorizing coastal enforcement officers to arrest offenders and enforce domestic penal statutes within the contiguous zone.

2. EEZ Environment Protection
Under Article 56 of the United Nations Convention on the Law of the Sea, the coastal State possesses sovereign rights and jurisdiction over the protection and preservation of the marine environment within its Exclusive Economic Zone, extending up to two hundred nautical miles. Coastal States retain authority to enforce environmental protection legislation against foreign vessels dumping hazardous substances or pollutants. Consequently, domestic trial courts possess jurisdiction to adjudicate environmental law violations committed by foreign vessels operating within the Exclusive Economic Zone.

3. Enforcement Coastal Jurisdiction
Foreign commercial vessels navigating beyond the territorial sea remain subject to coastal State jurisdiction for specific statutory violations occurring within recognized maritime zones. While innocent passage applies in the territorial sea, dumping toxic waste within twenty nautical miles infringes upon sanitary and environmental regulations governing the contiguous zone and Exclusive Economic Zone. Coastal authorities possess legitimate power to board, inspect, arrest, and prosecute foreign vessel officers, rendering motions to dismiss based on lack of territorial jurisdiction legally untenable.
