Factual Background

Petitioner was first charged with frustrated murder for shooting Hultman. After the prosecution rested, Hultman died. The private prosecutor moved to file and admit an amended information upgrading the charge to murder without holding a new preliminary investigation. The trial court granted the motion, entered a not‐guilty plea over petitioner’s refusal to be arraigned, and appointed a public defender when petitioner’s retained counsel abstained. Petitioner then petitioned for certiorari, prohibition, and mandamus to nullify these actions and compel a preliminary investigation.

Issues Presented

(a) Whether upgrading the charge from frustrated to consummated murder by amended information, filed after plea, is valid without a new preliminary investigation.
(b) Whether the appointment of a counsel de oficio is proper when petitioner’s counsel of choice refuses to participate.
(c) Whether the trial court may preferentially schedule petitioner’s trial over older criminal cases.

Legal Analysis and Rationale

  1. Amendment vs. Substitution
  • Under Rule 110, Sec. 14, an information may be amended in substance without leave before plea; after plea, amendments are limited to matters of form with leave. Substitution (charging a different offense) requires dismissal of the original information, leave of court, and a fresh preliminary investigation.
  1. Identity of Offenses
  • Frustrated murder is a stage of the crime of murder; both require intent to kill and qualifying circumstances (treachery, premeditation). The supervening fact of the victim’s death does not create a distinct offense but completes the same criminal act.
  1. Formal Amendment
  • Adding the fact of death is a formal amendment that does not alter the theory of the prosecution or prejudice petitioner’s defense. Under the 1987 Constitution, petitioner’s due process rights were preserved because the essential elements remained unchanged and no double jeopardy arose.
  1. Preliminary Investigation
  • A new preliminary investigation is unnecessary when the amended charge is formally related to the original and relies on the same facts. Requiring another hearing would impose needless delay.

Appointment of Counsel de Oficio

Because petitioner’s counsel of choice abstained, impeding the orderly conduct of trial, the trial court properly appointed a public defender to secure petitioner’s right to counsel
