Case Summary (G.R. No. 115838)

Petitioner

Siegfred D. Deduro, alleging repeated instances of “red-tagging,” surveillance, and public labelling as a Communist Party of the Philippines–New People’s Army (CPP-NPA) affiliate, with consequent threats to his right to life, liberty, and security.

Respondent

Maj. Gen. Eric C. Vinoya, sued in official capacity for acts or omissions of military personnel under his command.

Key Dates

• 22 October 2020 – Filing of Petition for Writ of Amparo before RTC Iloilo City.
• 26 October 2020 – RTC denies petition outright.
• 4 November 2020 – Petition for Review on Certiorari filed with the Supreme Court.
• 4 July 2023 – Supreme Court issues decision.

Applicable Law

• 1987 Constitution (post-1990 decision) – Articles on life, liberty, and security.
• A.M. No. 07-9-12-SC, Rule on the Writ of Amparo – Sections 1, 5, 6, 9–12, 14, 17–19.
• Rule 45, Rules of Court – appeal from final amparo orders.

Background Facts

• Deduro recounts multiple events of red-tagging: a June 19, 2020 Iloilo Provincial Peace and Order Council meeting where military officers identified him publicly as CPP-NPA hierarchy; posters in December 2017 and March 2019 labeling him and fellow activists as terrorists; surveillance by unidentified men in January 2019; red-tagging during a symposium in August 2019; further posters in August 2020 and social media posts in October 2020.
• Two individuals who appeared alongside Deduro in such materials—Jose Reynaldo Porquia and Zara R. Alvarez—were subsequently murdered, heightening Deduro’s fear.
• Deduro filed for writ of amparo, seeking protection orders, production of military records, destruction of existing dossiers, and an injunction against further red-tagging or harassment.

RTC Ruling

Branch 24, RTC Iloilo City issued an Order (26 Oct 2020) dismissing the petition for lack of prima facie proof of threats to life, liberty, or security. The court held that red-tagging and alleged surveillance, without more, did not amount to actionable threats under the Amparo Rule. The RTC did not require respondent to file a return.

Issues on Appeal

A. Whether Deduro established a prima facie case for issuance of the writ of amparo.
B. Whether the RTC erred in dismissing the petition without ordering a return or conducting a summary hearing.

Supreme Court’s Legal Framework on the Writ of Amparo

• Purpose: expeditious relief against extrajudicial killings, enforced disappearances, or threats thereof (Sec. 1).
• Initial evaluation (Sec. 6): petition must on its face show threatened violation of life, liberty, or security by unlawful act or omission of a public official or agent, supported by affidavit.
• Issuance of writ triggers respondent’s 72-hour duty to file a detailed return (Secs. 9–10).
• Summary hearing (Secs. 13, 18): evaluation of evidence by substantial-evidence standard; judgment within 10 days.
• Red-tagging, vilification, and guilt by association constitute actionable threats to life, liberty, or security.

Application of Law to Facts

• Deduro’s allegations and attached photographs establish at least a prima facie link between red-tagging by military units under respondent’s command and threats to his security, especially in light of subsequent killings of similarly labeled persons.
• Mere membership or inclusion in an order of battle does not suffice; but the combination of public military presentations, widely circulated posters, social media labelling,
