Facts

• On October 16, 1992, in Roxas City, Danilo (Danny) Buhat, armed with a knife, stabbed Ramon George Yu. Spouses Osmeña and Herminia Altavas joined in — he hitting the victim with his fists, she with a chair — while Renato Buhat and another person held the victim's arms to restrain him.
• On March 25, 1993 an Information for HOMICIDE was filed in the RTC of Roxas City, Branch 17 (Crim. Case No. C-3991) against Danny Buhat, "John Doe" and "Richard Doe."
• The body of that Information alleged that Buhat stabbed the victim while two unknown assailants held his arms, "using superior strength." That phrase, already present in the original, is what makes the later amendment merely formal.
• Before arraignment, private complainant Betty Yu appealed the prosecutor's resolution, and the prosecution moved to defer arraignment. Petitioner opposed, invoking his right to a speedy trial.
• On June 9, 1993 he was arraigned and pleaded "not guilty," and trial proceeded — the prosecution presenting at least two witnesses before the appeal was resolved.
• On February 3, 1994 Secretary of Justice Franklin M. Drilon found the appeal meritorious and ordered the City Prosecutor "to amend the information by upgrading the offense charged to MURDER and implead therein additional accused Herminia Altavas, Osmeña Altavas and Renato Buhat."
• On March 10, 1994 the Assistant City Prosecutor moved for leave to amend; petitioner opposed, calling it a prohibited substantial amendment.
• On June 2, 1994 Judge Jose O. Alovera denied the motion, reasoning that under Crespo v. Mogul the court is not bound by the Secretary's directive, and that the inquest prosecutor's findings were more persuasive.
• The Solicitor General brought certiorari (CA-G.R. SP No. 35554); on March 28, 1995 the Court of Appeals set the order aside, allowed the amendment to Murder, permitted the inclusion of the Altavases, and made its injunction permanent.
• On December 17, 1996 the First Division dismissed Buhat's petition but ordered a corrected Amended Information conforming to the Secretary's findings.

Issue

Ruling

"WHEREFORE, the petition is DISMISSED for lack of merit. The City Prosecutor of Roxas City is HEREBY ORDERED to file the correct Amended Information fully in accordance with the findings of fact set forth in the Resolution of the Secretary of Justice, dated February 3, 1994, and in disregard of the finding of the Court of Appeals in its Decision, dated March 28, 1995, in CA-G.R. SP No. 35554 to the effect that "Danny Buhat and Renato Buhat are one and the same person."

SO ORDERED."

Ratio

• The Court began from the text of Section 14: amendment "in form or substance without leave of court at any time before the accused enters his plea," but [a]fter the plea and during the trial, a formal amendment may only be made with leave of court and when it can be done without causing prejudice to the rights of the accused.
• The measure of prejudice is the Casey test — whether a defence under the original remains available, and whether the accused's evidence remains equally applicable. An amendment is formal if it does not change the nature of the crime, alter the prosecution's theory, cause surprise, or expose the accused to a higher penalty.
• On conspiracy the Court applied an exception, not the general rule. People v. Montenegro and People v. Zulueta treat a post-arraignment conspiracy allegation as substantial, because it attributes co-conspirators' acts to the accused. But under Regala v. CFI of Bataan, where "the principal accused's direct participation in the killing does not change," adding "conspiring, confederating and helping one another" is merely formal. Here both versions alleged that Buhat stabbed the victim while others held his arms — so his role as "the actual wielder of the knife remained identical," leaving his denial and alibi untouched.
• On the caption, the Court invoked U.S. v. Lim San: the technical name is "a mere conclusion of law formulated by the prosecutor," and the real question is not whether the accused committed a crime with a specific technical name, but whether he performed the acts alleged in the body. If he did, "the law determines the crime and the penalty."
• Applied, the original Information already charged Murder in substance. Abuse of superior strength being a qualifying circumstance under Article 248, the change of title "was merely a formal correction to make the designation conform to the facts already charged" — which is precisely what distinguishes this case from Dionaldo v. Dacuycuy, where the body lacked any qualifying circumstance.
• On double jeopardy, the original case "was never dismissed or terminated" — the trial court merely allowed the original Information to be amended on the same sheet of paper by crossing out 'Homicide' and writing 'Murder'. The Altavases "were never in prior jeopardy," not having been impleaded; and replacing "John Doe" with a real name is "a mere formal correction."

Doctrine

• "Notwithstanding apparent contradiction between caption and body, … the characterization of the crime by the fiscal in the caption of the information is immaterial and purposeless … the facts stated in the body of the pleading must determine the crime of which the defendant stands charged and for which he must be tried."
• The post-plea rule: "After the plea and during the trial, a formal amendment may only be made with leave of court and when it can be done without causing prejudice to the rights of the accused," the test being whether the accused's defence and evidence remain equally applicable.
• The Regala exception: adding conspiracy post-plea is a permissible formal amendment where the principal is already charged as such and his physical participation is unchanged.
• Designation conformity is form: where the body already alleges a qualifying circumstance, the Information already charges Murder as a matter of law, and changing the title is purely formal.

• The Dacuycuy rule is the boundary: upgrading Homicide to Murder after arraignment is proscribed and void where the body of the original Information alleged no qualifying circumstance — the accused having been informed only of Homicide.
• The Montenegro–Zulueta rule survives: alleging conspiracy post-arraignment is substantial, and must be disallowed over objection, where it fundamentally alters the prosecution's theory, introduces new elements, or attributes co-conspirators' independent acts to an accused not previously charged on that footing.
• Note what carried this case: not a general permission to upgrade charges, but the fact that "using superior strength" was already in the body and Buhat's role as stabber never varied.
• And note the disposition's sting — the Court dismissed the petition but corrected the Court of Appeals, ordering an Amended Information that does not treat "Danny Buhat and Renato Buhat" as the same person.

Facts

• October 16, 1992: Danilo (Danny) Buhat, armed with a knife, unlawfully attacked, stabbed, and injured Ramon George Yu in Roxas City. Spouses Osmeña Altavas (who continuously hit the victim with his fists) and Herminia Altavas (who hit the victim with a chair), together with Renato Buhat and another unidentified person (who held the victim's arms to restrain him), participated in the attack.
• March 25, 1993: The prosecution filed an Information for HOMICIDE in the Regional Trial Court (RTC) of Roxas City, Branch 17, docketed as Criminal Case No. C-3991, against petitioner Danny Buhat, "John Doe," and "Richard Doe." The body of the Information alleged that Buhat stabbed the victim while the two unknown assailants held the victim's arms, "using superior strength," which inflicted mortal wounds causing death.
• Subsequent Date (Exact Date NOT IN RECORD): Prior to arraignment, the private complainant Betty Yu filed an appeal/motion for reconsideration with the Office of the City Prosecutor of Roxas City to challenge the resolution ordering the filing of the Homicide Information. The prosecution subsequently filed a motion to defer the arraignment of the petitioner pending the resolution of this appeal.
• Subsequent Date (Exact Date NOT IN RECORD): Petitioner Danilo Buhat opposed the prosecution's motion to defer arraignment, invoking his constitutional right to a speedy trial.
• June 9, 1993: The RTC proceeded with the arraignment. Petitioner entered a plea of "not guilty" to the charge of Homicide under the original Information, and trial on the merits ensued.
• Subsequent Date (Exact Date NOT IN RECORD): The prosecution presented at least two witnesses in the trial before any resolution on the private complainant's appeal was issued.
• February 3, 1994: Then Secretary of Justice Franklin M. Drilon issued a Resolution finding Betty Yu's appeal meritorious and ordered the City Prosecutor of Roxas City "to amend the information by upgrading the offense charged to MURDER and implead therein additional accused Herminia Altavas, Osmeña Altavas and Renato Buhat."
• March 10, 1994: In compliance with the Secretary of Justice's directive, the Assistant City Prosecutor filed a Motion for Leave to Amend Information. Petitioner opposed the motion, claiming it constituted a prohibited substantial amendment.
• June 2, 1994: RTC Presiding Judge Jose O. Alovera issued an Order denying the prosecution's motion to amend the Information, on the grounds that: (a) under Crespo v. Mogul, the court is not bound to follow the Secretary of Justice's directive once an Information is filed, and (b) the inquest prosecutor's findings were more persuasive as he had observed the demeanor of the witnesses during the preliminary investigation.
• Subsequent Date (Exact Date NOT IN RECORD): The Solicitor General filed a Petition for Certiorari under Rule 65 before the Court of Appeals, docketed as CA-G.R. SP No. 35554, seeking to annul the June 2, 1994 RTC Order.
• January 30, 1995: The Court of Appeals issued a writ of preliminary injunction enjoining the RTC from proceeding with the trial under the original Homicide Information.
• March 28, 1995: The Court of Appeals rendered a Decision granting the petition for certiorari, setting aside the June 2, 1994 RTC Order, allowing the amendment of the Information to Murder, permitting the inclusion of Herminia Altavas and Osmeña Altavas as additional accused, and making the preliminary injunction permanent.
• Subsequent Date (Exact Date NOT IN RECORD): Petitioner Danilo Buhat filed the instant Petition for Review on Certiorari under Rule 45 before the Supreme Court of the Philippines, assailing the CA's decision.
• December 17, 1996: The Supreme Court First Division promulgated its Decision dismissing the petition, affirming the CA's ruling in principle, but ordering the City Prosecutor of Roxas City to file a corrected Amended Information that perfectly conforms to the specific findings of fact in the February 3, 1994 Resolution of the Secretary of Justice.

Arguments of the Parties

• Prohibited Substantial Amendment After Plea: Petitioner contended that upgrading the crime from Homicide to Murder after he had already entered a "not guilty" plea was a substantial amendment strictly prohibited under Section 14, Rule 110§ of the Rules of Court, as it altered the nature of the charge and exposed him to a much higher penalty (death or reclusion perpetua).
• Prejudice Caused by Conspiracy Allegation: He argued that adding the allegation of conspiracy ("conspiring, confederating and helping one another") was a substantial change that radically modified his defense. Invoking People v. Montenegro and People v. Zulueta, he claimed that the conspiracy allegation widened the "battlefront" and prejudiced him by allowing the prosecution to attribute the acts, admissions, and knowledge of the newly impleaded co-accused to him.
• Double Jeopardy: Petitioner claimed that proceeding under an upgraded charge of Murder after he was arraigned for Homicide violated his constitutional right against double jeopardy, asserting that the first prosecution was effectively terminated without his consent.

• Factual Sufficiency of original Information: The prosecution argued that the original Information, though captioned as Homicide, already contained factual allegations in its body that qualified the offense to Murder—namely, that petitioner stabbed the victim while two companions held the victim's arms, "using superior strength." Therefore, the change of designation in the caption to Murder was a mere formal correction of a conclusion of law.
• Formal and Non-Prejudicial Nature of Conspiracy Allegation: The prosecution asserted that adding the conspiracy allegation was a mere formal amendment because it did not change their core theory that petitioner acted as the principal actor who stabbed the victim. Invoking the exception in Regala v. Court of First Instance of Bataan, they argued that petitioner's defense was not compromised because his physical participation remained identical.
• Inapplicability of Double Jeopardy: The Solicitor General maintained that: (a) double jeopardy was inapplicable because the original Homicide case was never dismissed or terminated, and (b) the newly impleaded Altavases were never in prior jeopardy as they were not named in the original Information.
• Factual Error in the Amended Information: The Solicitor General filed a Comment and Motion highlighting that the Amended Information drafted by the Assistant City Prosecutor was factually defective because it failed to correctly reflect the findings of the Secretary of Justice (by alleging that the Altavases held the victim's arms, instead of Renato Buhat and an unknown person holding his arms while Herminia Altavas hit him with a chair and Osmeña Altavas punched him).

• Factual recitals in original Information: Both parties agreed that the original Homicide Information filed in Criminal Case No. C-3991 contained the factual recital that petitioner Danilo Buhat stabbed the victim Ramon George Yu while two unknown assailants held the victim's arms, "using superior strength."

Issue

1. Whether the post-plea inclusion of additional co-accused (Herminia Altavas and Osmeña Altavas) and the substitution of the real name of "Renato Buhat" for the fictitious name of "John Doe" constitutes a prohibited substantial amendment or violates the constitutional protection against double jeopardy under Section 7, Rule 117§ of the Rules of Court.
2. Whether the factual recitals in the body of an Information control over the technical designation of the offense in its caption or preamble under Sections 6, 8, and 9 of Rule 110§.

Ruling

• MAIN ISSUE: NO. The post-arraignment amendment upgrading the charge to Murder and alleging conspiracy is merely a formal, permissible amendment under Section 14, Rule 110§ of the Rules of Court because the body of the original Information already alleged the qualifying circumstance of "abuse of superior strength" and the petitioner's role as principal did not change.
• SECONDARY ISSUES:
  1. NO. The inclusion of the additional co-accused and the substitution of the real name "Renato Buhat" for the fictitious "John Doe" is a mere formal amendment that does not prejudice the rights of any accused or violate the rule against double jeopardy.
  2. YES. The factual allegations in the body of the Information control over the technical designation or title of the offense in the caption or preamble.

"WHEREFORE, the petition is DISMISSED for lack of merit. The City Prosecutor of Roxas City is HEREBY ORDERED to file the correct Amended Information fully in accordance with the findings of fact set forth in the Resolution of the Secretary of Justice, dated February 3, 1994, and in disregard of the finding of the Court of Appeals in its Decision, dated March 28, 1995, in CA-G.R. SP No. 35554 to the effect that "Danny Buhat and Renato Buhat are one and the same person."

SO ORDERED."

Ratio

1. The Post-Plea Amendment Rule under Section 14, Rule 110§: The Court began by analyzing the text of Section 14, Rule 110 of the 1985 Rules§ on Criminal Procedure (now Section 14, Rule 110§ of the 2000 Rules). Under this provision, an Information may be amended in form or substance without leave of court at any time before the accused enters his plea. However, once a plea has been ente§red:

   "After the plea and during the trial, a formal amendment may only be made with leave of court and when it can be done without causing prejudice to the rights of the accused." Therefore, the primary procedural inquiry is whether the post-arraignment amendment is formal or substantial.

2. The Test of Prejudice for Post-Plea Amendments: Under the Casey test, which the Court reaffirmed, the primary measure of whether an amendment causes prejudice to the accused is whether a defense under the original Information remains available after the amendment, and whether the evidence prepared by the accused continues to apply to the Information in its amended form. An amendment is formal if it does not change the nature of the crime, alter the prosecution's theory of the case, cause surprise, or expose the accused to a higher penalty.
3. Exception to the Rule Against Post-Plea Conspiracy Allegations (The Regala Doctrine): While People v. Montenegro and People v. Zulueta state that alleging conspiracy post-arraignment is generally a substantial amendment because it attributes the acts of co-conspirators to the accused, the Court recognized a vital exception established in Regala v. Court of First Instance of Bataan and People v. Court of Appeals (1983). When the principal accused's direct participation in the killing does not change under the amendment, adding the phrase "conspiring, confederating and helping one another" is merely a formal amendment. Here, both the original and amended Informations alleged that Danilo Buhat stabbed the victim while other persons held the victim's arms. Since his role as the actual wielder of the knife remained identical, the introduction of a conspiracy theory did not alter his defense of denial or alibi, causing him no surprise or prejudice.
4. Primacy of Factual Recitals in the Body of the Information (Rule 110§, Sections 6 and 9): Under Sections 6 and 9 of Rule 110§, an Information is sufficient if it states the name of the accused, the designation of the offense, and the acts or omissions complained of. The Court held that the technical name given to the crime in the caption is a mere conclusion of law formulated by the prosecutor. Quoting U.S. v. Lim San, the Court explained that the real question is not whether the accused committed a crime with a specific technical name, but whether he performed the acts alleged in the body of the Information. If he did, the law determines the crime and the penalty.
5. Factual Sufficiency of "Abuse of Superior Strength": In this case, while the original Information was captioned as "Homicide," its body explicitly alleged that Danilo Buhat stabbed the victim while two unknown companions held his arms, "using superior strength." Under Article 248 of the Revised Penal Code, "abuse of superior strength" is a qualifying circumstance that elevates a killing to Murder. Therefore, the original Information already legally charged the petitioner with Murder in its body. The amendment changing the title from "Homicide" to "Murder" was merely a formal correction to make the designation conform to the facts already charged, distinguishing this case from Dionaldo v. Dacuycuy where the body of the Information lacked any qualifying circumstances.
6. No Violation of Double Jeopardy (Rule 117§, Section 7): The Court rejected the petitioner's claim of double jeopardy. Under Section 7 of Rule 117§, double jeopardy requires that the first case was validly terminated by final acquittal, conviction, or dismissal without the accused's consent. Here, the original Homicide case was never dismissed or terminated; the trial court merely allowed the original Information to be amended on the same sheet of paper by crossing out "Homicide" and writing "Murder" in the caption. Furthermore, the Altavases were never in prior jeopardy as they were not impleaded in the original Information, and substituting the name "Renato Buhat" for the fictitious "John Doe" is a mere formal correction of a name that does not alter the prosecution's theory.

Doctrine

• The Primacy of Factual Recitals (The Lim San Rule):

  "Notwithstanding apparent contradiction between caption and body, . . . the characterization of the crime by the fiscal in the caption of the information is immaterial and purposeless . . . the facts stated in the body of the pleading must determine the crime of which the defendant stands charged and for which he must be tried." The technical name of the offense is a mere conclusion of law; the real issue of fact is whether the accused performed the specific physical acts described in the body of the Information.

• The Post-Plea Formal Amendment Rule (Rule 110§, Section 14):

  "After the plea and during the trial, a formal amendment may only be made with leave of court and when it can be done without causing prejudice to the rights of the accused." The test of prejudice is whether any defense or evidence originally prepared by the accused remains equally available and applicable after the amendment is admitted.

• The Formal Conspiracy Amendment Exception (The Regala Rule): While adding conspiracy is generally substantial, it is a permissible formal amendment if the principal accused is already charged as a principal in the original Information and his physical participation (e.g., as the stabber) remains completely unchanged under the amended Information.
• Designation Conformity as Form: If the body of an Information captioned as Homicide already contains allegations of qualifying circumstances (like abuse of superior strength), the original Information already charges Murder as a matter of law. Changing the technical designation in the title to Murder is a purely formal amendment that does not prejudice the accused's constitutional right to be informed of the nature and cause of the accusation.

• The Dacuycuy Substantial Amendment Rule: Changing the designation of the offense from Homicide to Murder post-arraignment is strictly proscribed and void as a substantial amendment under Section 14, Rule 110§ if the body of the original Information did not allege any qualifying circumstances. In such a case, the accused was only informed of Homicide, and upgrading the charge would violate his right to notice and due process.
• The Montenegro-Zulueta Rule: Alleging conspiracy post-arraignment is a substantial amendment that must be disallowed over the accused's objection if it fundamentally alters the prosecution's theory of the case, introduces new elements, or attributes the independent acts of co-conspirators to an accused who was not previously charged under such a theory.

• The relationship of Buhat v. Court of Appeals to the Topic of Prosecution of Offenses (Rule 110§) > IV. Complaint or Information > c. Amendment or Substitution is DIRECT.
• This case is the leading authority on the interplay between factual sufficiency (Sections 6, 8, & 9) and the post-arraignment amendment limitations (Section 14) of Rule 110§. It establishes that the restriction against post-plea substantial amendments is not a mechanical rule based solely on the caption of the offense. Instead, the court must look at the body of the original indictment. If the body already sufficiently alleged the qualifying facts, the accused's right to be informed has been fully satisfied. The prosecution is therefore allowed to formally amend the title of the crime to match the factual allegations. This case serves as a critical guide for law students and practitioners on how the "description of the criminal acts" in the body of the Information remains the supreme constitutional benchmark for evaluating the validity of post-plea amendments.
