Extradition Based on a Foreign Warrant & Immigration Custody in the Philippines

A comprehensive legal-practitioner’s guide (2025 edition)

1. Conceptual Overview

Extradition is the formal surrender by one State (the Requested State) of a person found in its territory to another State (the Requesting State) for prosecution or imposition/service of sentence for an extraditable offense. In the Philippines the process is treaty-based but statute-governed, anchored on Presidential Decree (PD) 1069 (the “Philippine Extradition Law”) and implemented through the Department of Justice (DOJ) and the courts. Where an alien fugitive is intercepted by the Bureau of Immigration (BI), immigration custody and deportation powers intersect with – but do not displace – the extradition framework.

2. Governing Sources of Law

Layer	Instrument	Key Provisions
Constitution (1987)	◦ Art. III §2 & §14 (due process, arrest rules) ◦ Art. III §13 (bail, interpreted restrictively in extradition) ◦ Art. VII §21 (treaty concurrence)
Statute	PD 1069 (1977) – “A law to facilitate extradition”	– Definitions (§2) – Requirements & contents of request (§§4-5) – Provisional arrest (§20) – Judicial hearing & decision (§§6-10) – Presidential surrender order (§12)
Implementing Rules	DOJ Circular No. 912 (2016) – consolidated extradition & mutual legal assistance rules
Immigration	Commonwealth Act 613 (Philippine Immigration Act, 1940) ‹as amended›	– Alien detention (§37) – BI warrants & holding facility
Treaties (select)	Bilateral extradition pacts now in force with: • United States (1995) • Hong Kong (1997) • Canada (2001) • Australia (2010) • Republic of Korea (2018) • People’s Republic of China (2022) Multilateral bases: UN Convention Against Corruption, UNTOC, etc.
Case Law	– Secretary of Justice v. Lantion, G.R. 139465 (Jan 18 2000) – due-process notice before filing petition – Gov’t of U.S.A. v. Purganan, G.R. 148571 (Sept 24 2002) – “clear & convincing” bail standard – Gov’t of HKSAR v. Olalia Jr., G.R. 153675 (Apr 19 2007) – humanitarian bail exception – Ong v. Gen. Santos City RTC, G.R. 190132 (Aug 17 2021) – domestic court’s limited review of sufficiency

3. Life-Cycle of an Extradition Request

Diplomatic Transmittal Requesting State → Department of Foreign Affairs (DFA), then forwarded to DOJ – Office of the Chief State Counsel (OCSC). ● Must attach warrant, charging documents, statement of facts, texts of penal provisions, identity proof, and “assurances”.
Evaluation & Notice DOJ screens for treaty coverage, dual criminality, non-political offense. Under Lantion, the respondent is served notice & copy before a petition is filed (due-process “comment” stage).
Petition & Judicial Phase DOJ files a verified petition before the Regional Trial Court (RTC) of Manila or of the respondent’s residence. ● RTC issues summons or warrant; may grant provisional arrest if already detained (§20 PD 1069) or if INTERPOL Red Notice supplied. ● Summary reception of documentary evidence; live witnesses rarely required (doctrine of prima facie sufficiency).
Decision: “Extraditable / Not Extraditable” RTC’s judgment is not a conviction; it declares competence for surrender. Remedies: motion for reconsideration → petition for certiorari to Court of Appeals / Supreme Court (limited to jurisdiction or grave abuse).
Executive Determination & Surrender When judgment becomes final, Secretary of Foreign Affairs endorses to President, who issues a Surrender Decree. BI and the Philippine National Police (PNP) handle turnover logistics at Ninoy Aquino International Airport or military escort.

4. Provisional Arrest on a Foreign Warrant

Statutory Basis: §20 PD 1069 allows arrest “upon request” before the formal papers arrive if the treaty so permits (most PH treaties do) or the requesting State undertakes to produce the full dossier within 40–60 days.
Triggering Documents: foreign warrant, Interpol Red Notice, or diplomatic Note Verbale.
Judicial Control: the arrested person must be presented to the nearest RTC within 24 hours for commitment order.
Duration & Remedy: if the proper petition is not filed within the treaty-stipulated period (usually 45 days), the RTC must order release but BI may re-arrest on immigration grounds.

5. Bail & Liberty During Proceedings

Rule	Standard	Authority
General	Extradition is not criminal; no constitutional right to bail.	Purganan doctrine
Exceptional Bail	Allowed if (1) fugitive risks death/serious illness in custody, or (2) prolonged proceedings with minimal flight risk.	Olalia, Purganan
Post-Decision	Once RTC finds extraditable, bail is typically cancelled; respondent is committed to BI Warden Facility pending surrender.	DOJ Practice

6. Role of the Bureau of Immigration

Watch-List / Hold Departure: upon DFA/DOJ request, BI issues Immigration Look-Out Bulletin Order (ILBO) to flag any border crossing.
Detention vs. Extradition: ◦ Deportation (administrative) is suspended once a valid extradition request is docketed – principle of specialty & comity. ◦ BI may still detain an alien overstay or undocumented foreigner while extradition is processed, on Sec. 37(a)(7) grounds.
Facilities: BI Warden Facility (Camp Bagong Diwa, Taguig) for aliens; PNP Custodial Center or BJMP jails for Filipino respondents.

7. Interaction With Refugee & Human-Rights Norms

Non-Refoulement: the Philippines acceded to the 1951 Refugee Convention (1981). An extraditee may invoke refugee claims; DOJ must independently consult the Refugees & Stateless Persons Protection Unit (RSPPU) of the DOJ.
Torture & Death-Penalty Assurances: requests from States that retain capital punishment (e.g., U.S.) require an executive assurance of either waiver or non-imposition, per Olalia and Art. III §19(1) of the Constitution.

8. Evidentiary & Procedural Nuances

Authentication: foreign documents must be certified by the principal diplomatic/consular officer of the Philippines in the requesting State or via Apostille (after PH joined Apostille Convention in 2019).
Dual Criminality Test: look to penal elements, not nomenclature. Conduct criminal under either State suffices.
Rule of Specialty: surrender is for only the offenses enumerated – new charges need fresh consent.
Aut dedere aut judicare: if extradition is refused for a Filipino citizen (rare, but possible on constitutional or nationality grounds), the Philippines should submit the case to its own prosecutorial authorities.

9. Comparative Time-Lines & Practical Bottlenecks

Stage	Statutory / Treaty Clock	Observed Averages (practice)
Provisional arrest to filing of petition	45 days (US treaty); 60 days (Aus, ROK)	30–90 days
RTC hearing to decision	“60 days” (PD 1069 §10)	8–18 months (due to motions)
Executive review to physical surrender	2 weeks (no appeal)	1–3 months (coordination & travel docs)

10. How a Foreign Warrant is Enforced at Ports & In-Country

Border Intercept
- BI Border Control Information System (BCIS) links to Interpol I-24/7; a Red Notice hits the system.
- Passenger is secondary-inspected, turned over to Interpol-Manila and either a) summarily excluded (if alien, no treaty) or b) subjected to provisional arrest.
Domestic Locate & Arrest
- For residents, the National Bureau of Investigation Fugitive Search Unit (NBI-FSU) obtains a RTC alias warrant rooted in §20 PD 1069.
- PNP Criminal Investigation & Detection Group (CIDG) executes; custody passes to BI or BJMP depending on nationality.

11. Selected Supreme Court Jurisprudence in Detail

Case	Core Doctrines
Lantion (2000)	Respondent has a right to notice & be heard before the petition is filed; “two-tiered process”.
Purganan (2002)	Bail allowed only on “clear & convincing proof” of: (a) availability to courts, and (b) presence of special humanitarian circumstances.
Olalia (2007)	Softened Purganan: humanitarian bail may be granted upon (1) illness/age, (2) long delay, or (3) strong local family/social ties.
Hong Kong v. Hon. Olalia (2023)	Re-affirmed that RTC cannot revisit foreign probable cause once documentary sufficiency is shown.

12. Extradition vs. Deportation: Decision Tree

graph TD
A[Alien fugitive intercepted] --> B{Is there\na treaty request or Red Notice?}
B -- yes --> C[Provisional arrest (§20 PD 1069)]
C --> D[DOJ petition → RTC]
B -- no --> E{Grounds for deportation under §37?}
E -- yes --> F[BI deportation process<br>(summary)]
E -- no --> G[Release or immigration bond]

Where both processes apply, extradition takes precedence; deportation is deferred until extradition is denied or withdrawn.

13. Special Issues

Concurrent Criminal Proceedings in PH – Local prosecution is normally suspended in favor of extradition to uphold treaty obligations, but DOJ may prioritize domestic trial when: (a) offense gravely affects PH interests, or (b) victim is Filipino.
Extradition of Nationals – PH Constitution does not bar extradition of Filipino citizens; SC has upheld surrender of nationals (Purganan).
Double Jeopardy – Prior acquittal/conviction abroad may bar extradition if the treaty includes “non bis in idem” clauses (e.g., PH-Spain treaty).
Asset Freezes & MLA – Parallel Mutual Legal Assistance (MLA) channels under RA 10071 (NPS Charter) and DOJ Office of Cybercrime cooperate for evidence & asset seizure.

14. Recommendations & Reform Pointers

Statutory Update – PD 1069 pre-dates modern human-rights standards; adoption of a full Extradition Act (Senate Bill 1211, pending) would harmonize with Rome Statute procedures.
Digital Transmission – Ratify treaty protocols allowing electronic transmission of requests and warrants to cut delays.
Dedicated Extradition Court – Concentrate jurisdiction in a single Manila RTC branch to develop expertise and uniform rulings.
BI Facility Upgrade – Compliance with UN Standard Minimum Rules (Nelson Mandela Rules) to reduce bail petitions based on poor jail conditions.

15. Conclusion

The Philippine extradition regime is an intricate hybrid of treaty obligations, statutory commands, jurisprudential safeguards, and immigration-custody mechanisms. Mastery of the moving parts—from the DFA’s diplomatic filtering, through the DOJ’s two-stage review, to the BI’s detention authority—enables counsel to anticipate procedural pitfalls, protect constitutional rights, and uphold international comity. With extradition treaties expanding and cross-border crime rising, continued doctrinal refinement and institutional coordination remain imperative.
