Case Summary (G.R. No. 93832)

Procedural Background: From Criminal Charge to Civil Suit

An information for violation of Section 4, R.A. No. 6425, was filed against Minucher (and Abbas Torabian) after a police buy‑bust at Minucher’s house in May 1986; the arrest involved Philippine narcotics agents and the private respondent, Arthur Scalzo. The accused were acquitted by the Pasig RTC on January 8, 1988. Minucher thereafter instituted Civil Case No. 88‑45691 in RTC Manila on August 3, 1988, claiming damages for what he alleged were trumped‑up drug trafficking charges instigated by Scalzo.

Factual Findings by the RTC (Narrative of Events)

The RTC summarized Minucher’s testimony: introductions between Minucher and Scalzo began May 13, 1986, through an informer (Jose Iñigo); commercial transactions (caviar, carpets) and social meetings occurred between May 13 and 27, 1986; Minucher paid Scalzo $2,000 for assistance with visas; on May 27, 1986, Scalzo led Minucher outside his house purportedly to meet a cousin; an American with a firearm and numerous Philippine soldiers then arrested Minucher and Torabian, handcuffed them, brought them back into the house, and conducted a search of the safe; large sums of money, carpets, jewelry and appliances were alleged missing; Minucher and Torabian were detained at Camp Crame for three days; the arrest and allegations were widely publicized internationally.

Pre‑trial Jurisdictional Battles and Early Motions

Scalzo’s counsel filed special appearances and motions, including a motion for extension of time to file an answer and a special appearance to quash summons on grounds of non‑residency and lack of personal jurisdiction. The trial court denied the quash motion, construing earlier motions for extension as a voluntary appearance. Appeals and petitions followed to the Court of Appeals and this Court, with mixed procedural rulings; at one point Scalzo was declared in default but later reinstated and permitted to file an answer denying material allegations and asserting affirmative defenses, including that he acted in discharge of official duties as a DEA agent. He later sought dismissal on grounds of diplomatic immunity and produced diplomatic notes and certifications in support.

Documentary Evidence and the Diplomatic‑Status Claim

Scalzo presented multiple documentary exhibits: Diplomatic Note No. 414 (May 29, 1990) and other subsequent diplomatic notes (Nos. 757 and 791), a Vice Consul certification, DFA endorsements and a November 18, 1992 letter from DFA’s Office of Protocol, DEA certifications and Scalzo’s investigation reports. These documents were offered to show that the U.S. Embassy and the Philippine Department of Foreign Affairs recognized Scalzo as a member of the U.S. diplomatic mission (listed as an Assistant Attaché) during October 14, 1985 to August 10, 1988, and that the U.S. asserted his diplomatic immunity.

Trial Court Decision and Appellate Reversal

On November 17, 1995 the RTC rendered judgment for Minucher, awarding actual, moral and exemplary damages and attorney’s fees; the RTC found that although Scalzo claimed diplomatic status and some evidence supported that claim, the challenged acts were committed outside the scope of official duties and thus he could be held personally liable. The Court of Appeals subsequently reversed, holding that Scalzo was sufficiently clothed with diplomatic immunity throughout his term of duty and thereby immune from Philippine criminal and civil jurisdiction pursuant to the Vienna Convention. This reversal precipitated the present petition for review.

Issues Presented to the Supreme Court in This Petition

The petition framed two central issues: (1) whether the doctrine of conclusiveness of judgment or res judicata precluded the Court of Appeals from resolving the appeal differently from the prior Supreme Court decision (G.R. No. 97765), and (2) whether Arthur Scalzo is entitled to diplomatic immunity or, alternatively, to state immunity for acts performed in an official capacity.

Doctrine of Conclusiveness of Judgment / Res Judicata Analysis

The Court summarized the elements of res judicata: finality of prior judgment, valid jurisdiction over subject matter and parties, judgment on the merits, and identity of parties, subject matter and causes of action. The Court explained that the prior Supreme Court decision (G.R. No. 97765) did not resolve the immunity question with finality because the earlier opinion expressly reserved the question of the authenticity of the diplomatic note and noted Scalzo’s reservation of his right to present evidence regarding his status. Consequently, the earlier disposition did not foreclose relitigation of the immunity question by final adjudication and could not be invoked as conclusive res judicata to bar the appellate court’s different resolution.

Legal Principles Under the Vienna Convention and Diplomatic Immunity

The Court reviewed the Vienna Convention’s codification of long‑standing customary international law on diplomatic immunity. It emphasized that full, blanket immunity (civil and criminal) is afforded only to “diplomatic agents” defined as heads of mission and members of the diplomatic staff; other categories (administrative, technical and service staff, consuls, attaches not accorded diplomatic rank) do not automatically receive such broad immunity. The Court stressed that the core inquiry is whether the person performs duties of a diplomatic nature; diplomatic immunity is to be applied restrictively.

Evidentiary and Authenticity Concerns About Post Litem Motam Diplomatic Notes

The Court observed that many of Scalzo’s diplomatic notes were issued post litem motam (after the litigation began) and that the trial court, and earlier Supreme Court scrutiny, reasonably questioned their authenticity and the undue delay in securing them. While the DFA’s Office of Protocol ultimately issued a certification indicating Scalzo was listed as an Assistant Attaché during the relevant period, the record lacked certified true copies of the underlying Department records used to produce that post litem motam certification, which gave the courts reason to be circumspect.

United States State Department Standards and Accreditation Criteria

The Court referenced the U.S. State Department’s standards for recognition of diplomatic agents: an acknowledged diplomatic title; performance of diplomatic duties; possession of a diplomatic passport or a diplomatic note assigning duties; relevant visa status; age and full‑time diplomatic function. These standards informed the inquiry into the functional nature of Scalzo’s activities in the Philippines and whether they were essentially diplomatic.

Doctrine of State Immunity and Relevant Philippine Jurisprudence

Beyond individual diplomatic immunity, the Court considered the doctrine of state immunity from suit: a State cannot be sued in the courts of another State without consent, and actions against officials acting in their official capacity may be regarded as actions against the foreign State itself. The Court cited United States of America v. Guinto to illustrate that officers acting within authority on behalf of their State are protected by state immunity. The Court also recited limitations: the immunity does not extend to acts outside authority, u
