G.R. No. L-19069 - People vs. Peralta

On December 21, 1960, at 10:00 A.M., the Chief of Police of Bacuag, Surigao del Norte, apprehended three suspicious-looking strangers loitering in Pagao, a sitio of Bacuag.
A bag in their possession was confiscated which contained:

Three carbines (caliber .30 M1) and one revolver (caliber .22);
Three flashlights with batteries;
Two fully loaded carbine ammunition magazines and twelve rounds of carbine ammunition;
A balisong and a screw driver;
Seven false keys, one of which was identified as a master (or picklock) key;
Personal effects including trousers, shirts, and a pair of shoes.

The accused—Ramon Lopez, Manuel Buico, and Arturo Caniete—faced charges in the Justice of the Peace Court of Bacuag for:

Illegal possession of firearms (to which they pleaded guilty);
Illegal possession of false keys (with Buico and Caniete pleading guilty, and Lopez pleading not guilty).

An investigation revealed that the items, particularly the false keys, were alleged to be possessed without lawful cause and included a picklock, implying an adaptation for the commission of robbery.

A separate information was filed in the Court of First Instance of Surigao del Norte, charging the accused with illegal possession of false keys under the Revised Penal Code (Article 301 in relation to Article 305).
The prosecution’s information alleged that on or about December 21, 1960, the accused willfully and unlawfully possessed seven false keys, one being a picklock or master key.
This charge was compounded by the fact that the same accused had been previously convicted on December 24, 1960, in Criminal Case No. 374 for illegal possession of firearms, an offense carrying a penalty of imprisonment and a fine.

Article 304 of the Revised Penal Code mandates that any person who, without lawful cause, possesses picklocks or similar tools especially adapted to the commission of robbery shall be punished.
The description of the false keys in the information was tied legally to Article 306, which defines “false keys” to include those tools mentioned in the preceding article (i.e., the picklocks).

Whether the facts stated in the information, which did not explicitly elaborate that the keys were "specially adapted to the commission of the crime of robbery," still constituted the offense of illegal possession of false keys.
Whether the inherent characteristic of one of the keys (being a picklock or master key) was sufficient to imply its adaptation for the commission of robbery.

Whether the omission of the phrase “specially adapted to the commission of the crime of robbery” in the information rendered the charge defective, or if the nature of a picklock automatically defines it as such.
Whether the legal definition of “false keys” as provided in Article 306 adequately encompasses picklocks or similar tools, thereby substantiating the charge.

How the previous conviction for illegal possession of firearms influenced the interpretation of the aggravating circumstances in the current charge.
