G.R. No. 128514 - People vs. Leones

Case Summary (G.R. No. 128514)

Factual Narrative: Seizure and Initial Control of M/T Tabangao

On the evening of March 2, 1991, the M/T Tabangao (PNOC-owned cargo vessel carrying kerosene, regular gasoline, and diesel oil, total value P40,426,793.87) was boarded off Mindoro by seven armed pirates led by Emilio Changco. The pirates used an aluminum ladder, were armed with M-16 rifles, handguns and bolos, detained the 21-man crew and took control of the vessel. The pirates had the vessel repainted and renamed "Galilee" (registry at San Lorenzo, Honduras), and sent misleading radio messages reporting repairs while they sailed away.

Factual Narrative: Voyage, Transfers, and Return

The pirates compelled the crew to sail to Singapore area; the vessel cruised near Singapore on March 9 and again anchored 10–18 nautical miles off Singapore on March 28. A transfer of cargo from the Tabangao (Galilee) to the Navi Pride was supervised by Cheong San Hiong; two ship-to-ship transfers were completed (March 29–30). The pirates later returned to Philippine waters; crew members were released in batches on April 10, 1991 with threats not to report the incident until April 12.

Reporting, Investigation, and Arrests

The crew reported the incident on April 12, 1991 to PNOC and the Coast Guard and executed sworn statements before the NBI. Surveillance and investigation led to arrests in May 1991: Tulin, Infante, and Loyola were captured following intelligence and surveillance; Cheong San Hiong and Cecilio Changco were arrested at Alpha Hotel, Batangas City. An Information for qualified piracy (violation of PD No. 532) was filed October 24, 1991.

Information, Trial, and Pleas

The Information charged the accused with qualified piracy (PD No. 532) for acts committed between March 2 and April 10, 1991 in Philippine jurisdictional waters, alleging conspiracy, boarding, seizure, violence and direction of the vessel to Singapore for unlawful disposition of cargo. On arraignment the accused pleaded not guilty and trial ensued.

Defenses Offered by the Accused

Tulin, Loyola, and Infante claimed denial and presented an alternative account that they were recruited as casual workers by the vessel’s officers on March 2 and denied travel to Singapore. Cecilio Changco maintained an alibi (at home sleeping on April 10). Cheong San Hiong asserted he was a bona fide Port Captain/agent for Navi Marine Services, participated as buyer/inspector in alleged legitimate ship-to-ship purchases brokered by Paul Gan, denied knowledge that cargo was pirated, and raised issues on jurisdiction and sufficiency of charge and proof.

Trial Court Findings and Conviction

The trial court found the prosecution’s witnesses—officers and crew of M/T Tabangao—credible and positively identifying the accused as pirates and conspirators. The court concluded that Emilio Changco and accused-appellants conspired to seize the vessel and its cargo, that transfers to Navi Pride were effected, and that Cheong San Hiong aided in disposition of the cargo. The trial court convicted Tulin, Loyola, Infante, and Cecilio Changco as principals of qualified piracy (Section 2(d), PD 532) and Cheong San Hiong as accomplice; imposed penalties including reclusion perpetua (death penalty could not be imposed due to the 1987 Constitution), orders for restitution to PNOC (P11,240,000.00) and to Caltex (P40,426,793.87) with interest, deportation of Hiong after service, and credit for detention under conditions.

Issues Presented on Appeal

The Supreme Court summarized the principal issues as: (1) legal effect of representation by a non-lawyer during trial; (2) effect of absence of counsel during custodial investigation and validity of confessions; (3) sufficiency of prosecution evidence to prove qualified piracy beyond reasonable doubt; (4) whether RA 7659 superseded PD 532 regarding piracy; and (5) whether Cheong could be convicted as accomplice when charged as principal and for acts allegedly outside Philippine waters.

Waiver of Counsel at Trial and Validity of Representation

The Court examined a written manifestation executed by certain accused on February 11, 1992 adopting proceedings handled earlier by a non-lawyer, Tomas Posadas. The Court held that waiver of right to representation at trial is permissible if made unequivocally, knowingly and intelligently with the full assistance of a bona fide lawyer. Because counsel Atty. Abdul Basar appeared and affirmed that the accused understood the nature and consequences of their manifestation and the accused confirmed this in open court, the Court found a valid waiver and that due process was not violated by the earlier non-lawyer representation (citing People v. Serzo and Sayson v. People).

Right to Counsel during Custodial Investigation and Inadmissibility of Confessions

The Court applied Section 12, Article III of the 1987 Constitution (right to be informed of right to remain silent and to have counsel; waiver valid only in writing and in presence of counsel) and the Miranda doctrine. It held that confessions or admissions obtained in violation of this constitutional right are inadmissible and that the “fruit of the poisonous tree” doctrine prohibits derivative evidence obtained from such unlawful confessions. The Court determined that uncounselled confessions in this case were inadmissible; however, it found other admissible evidence sufficient to support conviction beyond reasonable doubt.

Sufficiency of the Evidence, Conspiracy, and Credibility Findings

The Court affirmed the trial court’s credibility assessments: prosecution witnesses (master, officers, crew) consistently identified accused and recounted events; accused’s alternative narratives were implausible and uncorroborated. The Court stressed that determinations of witness credibility and demeanor by the trial court are to be accorded high respect. Conspiracy findings were upheld: co-conspirators need not participate in every detail and may perform separate tasks that, in combination, implement a single criminal design. The Court found coordination among accused (including logistical roles assigned to Cecilio Changco and others) sufficient to sustain conspiracy and principal liability for those so proven.

Evaluation of Cheong San Hiong’s Role and Liability

The Court addressed Cheong’s arguments separately. It concluded that PD 532 was not superseded by RA 7659; both laws operate harmoniously—PD 532 punishes piracy in Philippine waters and includes passengers and complement, while RA 7659 broadened Article 122 to include Philippine waters but did not repeal or nullify PD 532. Concerning Cheong’s locus of action and participation, the Court found the initial attack and seizure occurred in Philippine waters (thus within PD 532’s ambit), and that the subsequent disposition of the vessel and cargo abroad formed part of the piracy enterprise. The Court upheld the trial court’s finding that Cheong knowingly aided in disposition of the stolen cargo—supervising transfers, falsifying documents (General Declaration and crew list), certifying quantities, paying brokers, and arranging provisions—conduct that satisfied Section 4 of PD 532 (aiding or abetting pirates or acquiring property taken by pirates). The Court applied the presumption in Section 4 that one performing such acts did so knowingly, which Cheong failed to overcome.

Jurisdictional and Due Process Considerations for Cheong

Addressing the contention that Cheong was convicted as an accomplice though charged as principal, the Court noted established principle that if proof is insufficient to sustain pr

Facts of the Case

On the evening of March 2, 1991, M/T Tabangao, a cargo vessel owned by PNOC Shipping and Transport Corporation, was underway off the coast of Mindoro near Silonay Island.
The vessel was loaded with 2,000 barrels of kerosene, 2,600 barrels of regular gasoline, and 40,000 barrels of diesel oil, with a total value cited in the record as P40,426,793,87.
M/T Tabangao was manned by 21 crew members, including Captain Edilberto Libo-on, Second Mate Christian Torralba, and Operator Isaias Ervas.
Seven fully armed pirates, led by Emilio Changco (older brother of accused-appellant Cecilio Changco), suddenly boarded the vessel using an aluminum ladder, detained the crew, and took complete control of the ship.
The pirates included accused-appellants Roger P. Tulin, Virgilio I. Loyola, and Andres C. Infante, Jr., and were armed with M-16 rifles, .45 and .38 caliber handguns, and bolos.
Under the pirates’ control, the vessel’s name and identifying marks were altered: the name “M/T Tabangao” and the PNOC logo were painted over in black on the hull and chimney; the vessel was painted and renamed “Galilee,” with registry at San Lorenzo, Honduras.
The pirates forced the crew to sail toward Singapore while sending misleading radio messages to PNOC that the ship was undergoing repairs; PNOC lost radio contact and reported the disappearance leading to search efforts by the Philippine Coast Guard, Philippine Air Force, and Philippine Navy, which were unsuccessful.
The ship arrived in the vicinity of Singapore on March 9, 1991; pirates waited for a rendezvous that did not occur and were forced to return to the Philippines, arriving in the vicinity of Calatagan, Batangas on March 20, 1991, where the vessel remained at sea.
On March 28 and March 30, 1991, the vessel again anchored off Singapore and completed ship-to-ship transfers of cargo to another vessel, Navi Pride; accused-appellant Cheong San Hiong supervised the reception of cargo on board Navi Pride.
The first completed transfer occurred after interruptions; on March 30, 1991 the transfer from M/T Tabangao (Galilee) to Navi Pride was completed.
On April 8, 1991 M/T Tabangao arrived at Calatagan, Batangas but remained at sea; on April 10, 1991 members of the crew were released in three batches with stern warnings not to report the incident until April 12, 1991 or face death.
The first batch of released crew were picked up from the shoreline by a newly painted passenger jeep driven by accused-appellant Cecilio Changco; Cecilio brought them to Imus, Cavite and gave P20,000.00 to Captain Libo-on for the crew’s fare to their homes.
The second batch was similarly fetched by accused-appellant Cecilio Changco at midnight of April 10, 1991 and brought to different places in Metro Manila.
On April 12, 1991 the Chief Engineer and crew reported the incident to PNOC Shipping and Transport Corporation and to the Coast Guard and National Bureau of Investigation (NBI); sworn statements and affidavits were executed by ship officers and crew.

Arrests and Criminal Information

Following the report and NBI investigation, a series of arrests were effected:
- May 19, 1991: NBI, after surveillance at U.K. Beach, Balibago, Calatagan, Batangas, arrested accused-appellant Roger P. Tulin and brought him to NBI headquarters in Manila.
- Around the same time NBI agents arrested accused-appellants Andres C. Infante, Jr. and Virgilio I. Loyola at Aguinaldo Hi-way while pursuing the mastermind who evaded arrest.
- May 20, 1991: Accused-appellants Cheong San Hiong and Cecilio Changco were arrested at the lobby of Alpha Hotel in Batangas City.
October 24, 1991: An Information was filed charging qualified piracy (violation of Presidential Decree No. 532 — piracy in Philippine waters) against Roger P. Tulin, Virgilio I. Loyola, Cecilio O. Changco, Andres C. Infante, and Cheong San Hiong, and nine (9) other John Does, for acts occurring from March 2 to April 10, 1991, alleging conspiracy, boarding, seizing, and directing the vessel to Singapore where cargo was unloaded.

Trial: Pleas, Proceedings and Representation

The case was docketed as Criminal Case No. 91-94896 before Branch 49, Regional Trial Court of the National Capital Judicial Region, Manila.
Upon arraignment, the accused-appellants pleaded not guilty; trial was conducted and evidence adduced.
During trial, the accused-appellants were at some stage represented by Mr. Tomas Posadas, who later was discovered not to be a member of the Philippine Bar.
A manifestation (Exhibit “20”) was executed by accused-appellants Tulin, Loyola, Cecilio Changco, and Infante, Jr. on February 11, 1991, stating they adopted the evidence taken when represented by Mr. Posadas; later, while represented by Atty. Abdul Basar, they reaffirmed in open court (tsn, February 11, 1992, pp. 7-59) that they were apprised of the nature and consequences of that manifestation and had voluntarily and intelligently executed it.

Defense Theories and Testimony of Accused-Appellants

Roger P. Tulin, Virgilio I. Loyola, and Andres C. Infante, Jr.:
- Maintained denial of the charges and disputed the alleged transfer of cargo to Navi Pride.
- Testified inconsistently about their whereabouts on March 1, 1991 but claimed they were hired on March 2, 1991 by Captain Edilberto Liboon and Second Mate Christian Torralba who approached them by the beach and offered work on board M/T Tabangao at P3,000.00 per month.
- Claimed to have had no sea experience, performed menial tasks (cooking, cleaning, errands), and alleged they were paid P1,000.00 each for nineteen days upon arrival in Batangas on March 21, 1991; they had no written employment contracts or receipts.
- Asserts independent livelihood sources and denied going to Singapore.
Cecilio O. Changco:
- Categorically denied participation; testified he was at home sleeping on April 10, 1991.
- Identified as the younger brother of Emilio Changco, and as a person who fetched released crew from the shoreline.
Cheong San Hiong (aka Ramzan Ali):
- Presented credentials: studied in Sydney, held a “Certificate” as Chief Officer and a Master’s course; worked as a Master for two years and was employed as Port Captain by Navi Marine Services, Pte., Ltd., which traded petroleum and owned Navi Pride.
- Described company dealings with broker Paul Gan for the purchase of bunker oil; narrated his role supervising ship-to-ship transfers off Singapore, taking soundings and samples, supervising two transfers purportedly involving M/T Galilee, dealing with brokers and surveyors, receiving payment, and reporting to his company on March 29–30, 1991.
- Asserted he did not know the full identity of the M/T Galilee’s captain beyond the name “Captain Bobby,” which later was shown to be Emilio Changco; claimed he acted as a broker/port captain in supervising transfers and had been billeted at Alpha Hotel under the name “SONNY CSH” where he met Emilio Changco (alias Kevin Ocampo).

Prosecution Evidence and Identification

The prosecution presented testimony of the master, officers and members of M/T Tabangao’s crew, who identified and pointed to the accused as among those who attacked and seized the vessel on March 2, 1991 and who supervised and participated in the voyage to areas off Singapore where the cargo was transferred and sold.
A Joint Affidavit (Exhibit “B”) executed by Benjamin Suyo, Norberto Senosa, Christian Torralba and Isaias Wervas identified the accused as some of the pirates.
Documentary and circumstantial evidence included alterations of the vessel’s name and marking, the surfacing of M/T Tabangao (renamed Galilee) off Singapore, cargo transfer documentation (quantity certificates, general declarations, crew lists) connected to Navi Pride and Navi Marine Services, and the alleged sale proceeds.
Trial court credited prosecution witnesses’ categorical identifications over the accused-appellants’ bare denials.

Trial Court Findings and Disposition

After trial, the trial court rendered a 95-page decision convicting accused-appellants Tulin, Loyola, Infante, Jr., and Cecilio Changco as principals of qualified piracy under
