Facts

Pascua’s written application alleged that PICOP’s “Blue Guards” possessed numerous unlicensed firearms—M16 rifles, AK-47s, grenade launchers, handguns, ammunition, hand grenades—hidden within a 155-hectare compound containing hundreds of structures. The application attached affidavits, a joint deposition of Bacolod and Morito, and informant statements. At the hearing, only Bacolod was examined; Pascua and other deponents did not appear or affirm their statements. The RTC issued the warrant, and the SOU executed it, seizing dozens of firearms and thousands of rounds of ammunition. PICOP filed motions to quash and suppress; the RTC denied them. Petitioners then filed a Rule 65 petition in the Supreme Court.

Issues

  1. Whether the RTC abused its discretion in issuing Search Warrant No. 799(95) for lack of sufficient probable cause and for violating the prohibition against general warrants.
  2. Whether the warrant was unlawfully served or implemented.
  3. Whether State Prosecutor Dacera abused his discretion by proceeding with IS No. 95-167 based on evidence allegedly seized under an invalid warrant.

Preliminary Issue: Questions of Law vs. Fact

The Supreme Court held that petitioners challenged procedural violations of the Constitution and Rules in issuing the warrant—purely legal questions—and thus Rule 65 certiorari was appropriate.

Validity of Search Warrant: Personal Examination

Under the 1987 Constitution and Rule 126, the judge must personally examine the complainant and witnesses under oath, in writing, and attach sworn statements. Here, the RTC only administered oath and took testimony from Bacolod; Pascua and other deponents were never personally examined. Reliance on affidavits alone is insufficient and contrary to established doctrine requiring probing, exhaustive judicial inquiry.

Validity of Search Warrant: Personal Knowledge

Bacolod’s testimony was based on “belief” drawn from informant reports and surveillance, not on facts within his personal knowledge that PICOP or its security detail lacked licenses. No certification from the Firearms and Explosives Office was produced. The absence of the best available evidence concerning licensing, without justification, rendered probable cause improperly established.

Validity of Search Warrant: Particularity

The warrant described only the entire PICOP compound—“Barangay Tabon, Bislig, Surigao del
