G.R. No. L-5221 - Ferrer y Rodriguez vs. Pecson

On February 2, 1949, petitioner Benito Ferrer y Rodriguez, while driving a jeepney along Dapitan Street in Manila, allegedly operated his vehicle in a careless, reckless, and imprudent manner.
The reckless driving resulted in the petitioner side‑swiping another jeepney, causing a collision.
The collision inflicted serious physical injuries on a passenger, Avelino Tiu, which included:

The victim’s injuries required, and would continue to require, medical attention for a period estimated between six (6) and eight (8) months, thereby preventing him from engaging in his customary labor.

Following the incident, petitioner was charged before the Municipal Court of Manila under criminal case No. 10050 for serious physical injuries through reckless imprudence.
After trial, the Municipal Court found petitioner guilty and imposed a sentence of three (3) months of arresto mayor.

Petitioner appealed the Municipal Court’s decision by elevating the case to the Court of First Instance of Manila.
On November 27, 1950, petitioner, through counsel, filed a motion to dismiss the case on the grounds that the Municipal Court of Manila lacked jurisdiction over an offense punishable by a term exceeding its competency.
Initially, Judge Potenciano Pecson denied the motion to dismiss. However, on a subsequent motion for reconsideration dated June 6, 1951 (Annex D), he granted the motion and dismissed the case for lack of jurisdiction.
Later, on August 29, 1951 (Annex E), Judge Pecson, responding to a motion for reconsideration by the fiscal, revoked his earlier dismissal order, thereby reinstating his December 14, 1950 ruling that denied the motion to dismiss.
Counsel for petitioner Ferrer petitioned for a further reconsideration; upon its denial on October 31, 1951 (Annex I), the petitioner filed the present petition for certiorari seeking to revoke the August 29, 1951 order and reinstate the June 6, 1951 order dismissing the case.

At the time the complaint was filed (March 1, 1949), the applicable law was the Revised Motor Vehicle Law (Act No. 3932), specifically Section 67, which penalized acts of negligence or reckless driving resulting in serious physical injuries with imprisonment from a minimum of fifteen (15) days to a maximum of six (6) years.
The amended provisions provided by Republic Act No. 587, which took effect on January 1, 1951, reclassified such offenses to be prosecuted under the Revised Penal Code. However, this amendment was not given retroactive effect.
The jurisdiction of the Municipal Court, as defined by the Judiciary Act of 1948, was limited to offenses carrying a penalty not exceeding six (6) months, a constraint central to the controversy in this case.

Whether the Municipal Court of Manila had the jurisdiction to try a criminal case involving an offense with a potential penalty of up to six (6) years.
Whether the Court of First Instance possessed appellate jurisdiction over a case that originated in a court lacking proper original jurisdiction.

Whether Republic Act No. 587, which amended the applicable law by allowing prosecution under the Revised Penal Code, should be applied retroactively to confer jurisdiction on the Municipal Court.
Whether petitioner’s choice to invoke the Revised Motor Vehicle Law (in force at the time of the commission of the offense) precludes the retroactive application of the more favorable amended provisions.

The validity of the multiple orders—first denying, then granting, and subsequently revoking the dismissal of the case—issued by Judge Pecson.
The appropriateness of granting certiorari to reinstate the dismissal order based on lack of jurisdiction.
