G.R. No. 248974 - Heirs of Tulauan vs. Mateo

On September 10, 1950, at about noon, a customs patrol team aboard Patrol Boat ST-23 intercepted five Philippine‐registered sailing vessels on the high seas, between British North Borneo and Sulu.
The vessels were en route to Tawi-tawi, Sulu, indicating an intention to enter domestic waters despite originating from a foreign port.

The cargo was significant in that it violated importation regulations, lacking both the necessary permit from the Commissioner of Customs and the required import license under Republic Act No. 426.

The vessels and their cargo were declared forfeited for violation of Section 1363(a) of the Revised Administrative Code and Section 20 of Republic Act No. 426, in connection with Section 1363(f) of the Revised Administrative Code.
The apprehension and seizure were conducted in accordance with these statutory provisions, which explicitly cover vessels unlawfully engaged in the importation of merchandise, irrespective of whether the place of importation had yet been reached.

The seizure was initially conducted by the customs patrol, followed by a decision of the Collector of Customs of Jolo ordering forfeiture of the vessels and cargo.
The petitioner-appellants, owners of the vessels, challenged the seizure on two primary grounds:

Jurisdiction – contending that since the interception occurred on the high seas, the vessels had not yet engaged in importation into Philippine territory.
Due Process and Legal Validity – arguing that the seizure and forfeiture were in violation of due process rights and that the expiration of Republic Act No. 426 should have abated any liability.

The action taken by Customs was anchored on an overarching government policy aimed at curtailing smuggling and its associated evils, a policy that does not tolerate circumvention even when technical arguments are raised regarding territorial boundaries.
The vigorous language used in earlier decisions underscored that it would be irrational for Philippine vessels, manned by Filipino sailors, to engage in smuggling by deliberately avoiding legal importation procedures.

Whether the seizure of the vessels on the high seas, beyond the territorial waters of the Philippines, falls within the jurisdiction of the Commissioner of Customs.
Whether the vessels, although intercepted outside the territorial limit, were unquestionably bound for a Philippine port, thereby justifying seizure.

Whether the seizure and forfeiture of the vessels and cargo were legally justified under Section 1363(a) and (f) of the Revised Administrative Code and related importation laws.
Whether the action taken by the Commissioner of Customs adhered to the due process requirements under the law.

Whether the repeal or expiration of Republic Act No. 426 (or its referenced counterpart) abated any legal liability, thus challenging the validity of the seizure and forfeiture.
Whether the jurisdiction acquired by the Commissioner of Customs prior to the expiration of the law remains intact and enforceable.
