G.R. No. 116001 - People vs. Go y Ko

On October 22, 1992, SPO1 Mauro Piamonte and SPO3 Candido Liquido, members of the Calamba Police Intelligence and Follow-up Unit, received an intelligence report about methamphetamine hydrochloride ("shabu") being supplied at Crossing, Calamba, Laguna.
Police civilian agent Ronnie Panuringan observed accused-appellant Luisito Go, alias "King Louie," entering Flamingo Disco House with two women and noticed a gun tucked at appellant’s waist.
The policemen, accompanied by a waiter, went to the disco, identified themselves, and asked appellant to stand. The gun was plainly visible; appellant could not produce a license but instead presented a driver's license of a certain Tan Antonio Lerios. The police confiscated a 9mm Walther P88 firearm with ten live rounds.
Appellant was invited for questioning at the police precinct after being asked for his car parked outside. Police noticed a Philippine National Police (PNP) ID hanging inside the car, which appellant denied owning. He failed to produce driver’s license and vehicle registration papers.

Police saw glass tooters and tin foils inside the car; appellant remained silent and suggested talking at the police headquarters, intimating he had money.
On opening an attaché case in appellant’s possession, police found two black clutch bags; one contained shiny white crystalline substance wrapped in cellophane, and the other contained P120,000 in cash.
At the police station, investigation revealed eight cellophane bags containing suspected shabu inside one clutch bag and drug paraphernalia inside the attaché case, including three glass tooters, tin foils, an improvised burner, magazines, and newspapers.

Criminal Case No. 3308-92-C for possession of 750.39 grams of methamphetamine hydrochloride in violation of Article III of R.A. 6425 (Dangerous Drugs Act).
Criminal Case No. 3309-92-C for illegal possession of a firearm in violation of P.D. 1866.

The Regional Trial Court (RTC) found appellant guilty beyond reasonable doubt in both cases. Sentence for the drug charge was imprisonment of 6 years 1 day to 12 years and a fine of P12,000; for illegal firearm possession, reclusion perpetua.
Appellant posted bond which was later cancelled due to detention at the Makati Police Station.

Appellant appealed the firearm conviction directly to the Supreme Court (G.R. No. 116001) due to the severe penalty imposed.
Appeal on the drug conviction was filed with the Court of Appeals (CA).
The CA affirmed appellant’s conviction but modified the drug penalty to imprisonment of 6 years and 1 day to 12 years plus a fine of P6,000, citing Section 8 of R.A. 6425 and subsidiary imprisonment in case of insolvency.
The two cases were consolidated for review by the Supreme Court.

Whether the warrantless arrest of accused-appellant was valid.
Whether the subsequent search and seizure of the firearm, shabu, and drug paraphernalia were lawful and admissible.
Whether appellant’s guilt for illegal possession of firearm and shabu was proven beyond reasonable doubt.
Whether appellant’s claim of possession of a valid firearm license exonerates him from illegal possession of firearm charge.
What is the appropriate penalty for illegal possession of firearm under the amended law.
