G.R. No. L-2621 - People vs. Guanco

On June 30, 1946, appellant Jesus Guanco drove a jeep along the public highway between the municipalities of Hinigaran and Pontevedra, Negros Occidental.
The jeep, while being driven at a speed between 50 to 60 miles per hour—which exceeded the legal limit—zigzagged and overturned into a ditch.

As a result of the accident, four of the fourteen passengers in the jeep were killed.
The accident occurred when the vehicle lost control due to high speed, leading to the fatalities.

Appellant Jesus Guanco was charged with violating Act No. 3992 (Motor Vehicle Law) for operating a motor vehicle without a proper license, as he was less than 18 years of age and did not possess the required license, in violation of Section 27 of the Act.
In another related prosecution, he was charged and convicted of multiple homicide through reckless imprudence, with the court noting that his action of driving without a license was indicative of negligence.
The separate case concerning multiple homicide resulted in a conviction by the Court of First Instance of Negros Occidental and was later affirmed by the Court of Appeals, which ordered his commitment to the Training School for Boys under a suspended sentence pursuant to Article 80 of the Revised Penal Code.

The initial trial in the Justice of the Peace Court of Hinigaran, Negros Occidental, resulted in a conviction for violation of the Motor Vehicle Law, with a sentence imposing a fine of P50 and subsidiary imprisonment for insolvency along with an order to pay costs.
Appellant moved for a new trial, which was denied, and subsequently, he appealed to the Court of Appeals.
The appellant argued that the two prosecutions constituted double jeopardy, claiming that being convicted in the case of multiple homicide through reckless imprudence and then separately for the violation of the Motor Vehicle Law put him in jeopardy twice for essentially the same act.

Whether prosecuting appellant for the violation of Section 27 of Act No. 3992 (operating a motor vehicle without a license) is barred because of his earlier conviction for multiple homicide through reckless imprudence.
Whether the facts in the two cases overlap to such an extent that they amount to a single offense, thereby constituting double jeopardy.

Whether the specific charge in the present case (driving without a license) is legally distinct from the charge of reckless imprudence resulting in multiple homicide, despite sharing the common factual background of operating the vehicle on the day of the accident.
