G.R. No. 27120 - Agapito vs. Molo

Rodrigo Yorac, the accused, was initially prosecuted for slight physical injuries arising from an assault on the offended party, Lam Hock.
The assault involved hitting Lam Hock with a piece of wood, an act for which Yorac pleaded guilty, resulting in an earlier conviction.

The prosecution occurred before the City Court of Bacolod, with Lam Hock as the offended party.
On April 10, 1968, a medical certificate issued by Dr. Rogelio Zulueta indicated that Lam Hock suffered a head injury severe enough to warrant confinement starting on April 8, 1968.
Yorac pleaded guilty on April 16, 1968, and was sentenced to ten days of arresto menor, which he began serving immediately.

Despite the prior conviction, the provincial fiscal filed an information on April 18, 1968, before the Court of First Instance of Negros Occidental.
This new prosecution charged Yorac with frustrated murder arising from the same act against Lam Hock.
A second medical certificate, dated April 17, 1968, issued by the same physician, purportedly showed that Lam Hock sustained a greater injury – specifically noting a contusion with a lacerated wound in the parietooccipital region and a moderately severe cerebral concussion.
The physician also clarified that there was no radiographic evidence of fracture, and the healing period was estimated to be eighteen to twenty-one days.

On June 10, 1968, Rodrigo Yorac filed a motion to quash the information for frustrated murder, invoking the defense of double jeopardy.
Yorac argued that since he had already been convicted and punished for slight physical injuries – an offense inherently included within the charge of frustrated murder – subjecting him to a second prosecution would violate his constitutional rights.
The Honorable Judge Nestor B. Alampay granted the motion on June 21, 1968, dismissing the criminal case for frustrated murder and ordering the immediate release of the accused.

The People of the Philippines, as appellants, appealed the lower court’s resolution.
The issue raised was whether the subsequent prosecution for frustrated murder, based on a revised medical certificate, could be sustained without violating the double jeopardy rule.

Whether the subsequent prosecution for frustrated murder, following a prior conviction for slight physical injuries resulting from the same act, violates the constitutional protection against double jeopardy.
Whether the second, more detailed medical certificate published a new or supervening fact justifying a new and distinct offense that could warrant a charge of frustrated murder.
Whether the principle from People v. Buling and related precedents (such as People v. Tarok, Melo v. People, and others) applies in barring the second prosecution.
