Facts

• On July 15, 1994 Ellen Vertudazo, whose husband worked in Saudi Arabia, moved with her children into a rented apartment in Barangay Punta, Ormoc City. She knew her neighbour Roneto Degamo alias "Roy" only by sight.
• On September 30, 1994 Degamo invited her brother-in-law Venancio out for the night; Venancio left saying he would return.
• On October 1, 1994 at 1:00 a.m., hearing her name called and believing Venancio had returned, she opened the door. Degamo forced his way in, poked a knife at her neck, threatened to kill her if she resisted or screamed, ordered the light off and her clothes removed, and raped her on the concrete floor while holding the knife.
• That morning she reported to the Barangay Captain and the police. On October 3 a medical examination found no traumatic injury and no spermatozoa — the examination having occurred more than 48 hours after the act.
• On October 4, 1994 a complaint for Rape was filed in the RTC of Ormoc City, Branch 12.
• On November 8, 1994, her trauma worsening, she was brought to psychiatrist Dr. Gemelina Cerro-Go, who diagnosed acute and chronic psychosis (insanity) induced by the rape. The diagnosis came a month after the complaint — the fact that makes the amendment a supervening event.
• Degamo was arraigned on the original complaint and pleaded not guilty.
• On January 17, 1995, before trial proper, the prosecution moved to amend the complaint to allege that "by reason of the incident of rape, the victim has become insane" under Article 335. The trial court granted the motion over the defense's silence, and Degamo was re-arraigned and again pleaded not guilty.
• On February 16, 1995 Dr. Go testified that the psychosis was equivalent to insanity, that the victim had not fully recovered, and that treatment would take six months to five years.
• On May 22, 1995 the RTC convicted him of qualified rape and imposed DEATH. Decided En Banc, April 30, 2003.

Issue

Ruling

"WHEREFORE, the judgment of the lower court convicting appellant Roneto Degamo alias "Roy" of qualified rape and sentencing him to suffer the penalty of DEATH is AFFIRMED with the MODIFICATION that appellant is ordered to pay complainant Ellen Vertudazo the amounts of Seventy-Five Thousand Pesos (P75,000.00), as civil indemnity; Fifty Thousand Pesos (P50,000.00), as moral damages; Twenty-Five Thousand Pesos (P25,000.00) as exemplary damages; and Twenty-Five Thousand Pesos (P25,000.00) as temperate damages. Costs against appellant."

Ratio

• The Court applied the Teehankee guidelines. A substantial amendment "consists of a recital of facts constituting the offense charged and determinative of the jurisdiction of the court. All other matters are merely of form." Expressly formal are: allegations relating only to the range of the penalty; amendments that do not charge a different offence; additional allegations that do not alter the prosecution's theory so as to cause surprise; and those that do not adversely affect a substantial right, such as the right to invoke prescription.
• The prejudice test: "whether or not a defense under the information as it originally stood would be equally available after the amendment is made, and whether or not any evidence which the accused might have would be equally applicable … if the answer is in the affirmative, the amendment is one of form and not of substance."
• Applied, all four markers pointed to form: the crime remained rape under Article 335; the addition related only to the range of the penalty; his defences of denial and "illicit love affair" remained equally available; and his evidence was not rendered inapplicable.
• The supervening-event branch is what makes the case distinctive. Following Melo v. People, amending to charge a more serious offence raises no double jeopardy where the factual basis of the more serious charge did not exist at the time of filing but arises as a subsequent event.
• And insanity is peculiarly suited to that treatment: it "is a clinical and psychiatric condition that is not always readily discernible immediately after the commission of the crime," and "may take weeks or even months of psychiatric observation and treatment" before a diagnosis is possible.
• Objection was in any event waived. "Objection to the amendment of an information or complaint must be raised at the time the amendment is made, otherwise, silence would be deemed a consent to said amendment" — and such objections "cannot be raised for the first time on appeal."
• On the meaning of "insane" the Court used legislative history. Under R.A. No. 2632, Senator Pedro Sabido had proposed "perpetual incapacity or insanity," but the legislature deliberately deleted "perpetual." Hence "the courts should not interject a condition, make a distinction, or impose any limitation where the legislators did not opt to do so" — so it suffices that the post-traumatic insanity is clinically manifest at the filing of the complaint or any time before judgment.

Doctrine

• A substantial amendment "consists of a recital of facts constituting the offense charged and determinative of the jurisdiction of the court"; formal amendments include those relating only to the range of the penalty, those not charging a different offence, those not altering the prosecution's theory, and those not affecting a substantial right.
• The prejudice test asks whether the original defence and evidence remain equally available and applicable.
• Supervening events: an amendment charging a more serious offence raises no double jeopardy where its factual basis arose after the original filing — and post-traumatic insanity, being clinically undiagnosable at once, qualifies.
• Waiver: objection to an amendment "must be raised at the time the amendment is made," silence being consent.
• "Has become insane" is unqualified: the degree of insanity is irrelevant, the legislature having deleted "perpetual."
• Evidence: neither the weapon, nor genital trauma, nor spermatozoa is indispensable.

• The formal/substantial line still holds elsewhere — this amendment escaped it only because it added no new offence and touched only the penalty range; adding a qualifying circumstance that changes the crime charged remains proscribed after plea. Compare Pacoy v. Cajigal, where the label moved from Homicide to Murder but no circumstance was added, and Buhat v. CA, where the qualifying circumstance was already in the body.
• The supervening-event rationale is tied to its facts: what justified it was that the insanity was medically undiscoverable at filing — an amendment adding a circumstance the prosecution simply failed to plead would not qualify.
• Note that the accused was re-arraigned anyway, so the notice objection had little purchase; and his silence at the amendment waived the point regardless.
• And note the death sentence: this is a pre-R.A. No. 9346 decision, so the penalty as imposed no longer reflects current law even though the procedural holding stands.

Facts

1. July 15, 1994: Complainant Ellen Vertudazo, a married woman whose husband was working as an overseas contract worker in Saudi Arabia, moved with her children into a rented apartment in Barangay Punta, Ormoc City. Complainant was not personally acquainted with their neighbor, appellant Roneto Degamo alias "Roy," but knew him by sight.
2. August 2, 1994: Complainant's brother-in-law, Venancio, arrived from the province for a visit and stayed at complainant's house, where he subsequently became acquainted with appellant.
3. September 30, 1994: Appellant invited Venancio for a night out. Venancio left complainant's house immediately after supper, telling her that he would return.
4. October 1, 1994 (1:00 a.m.): Complainant heard someone calling her name from outside the house. Believing that Venancio had returned, she unwittingly opened the door of her apartment. Appellant immediately forced his way inside, poked a knife at complainant's neck, and threatened to kill her if she resisted or screamed. He commanded her to turn off the light, strip off her clothes, and lie on the concrete floor, where he proceeded to have carnal knowledge of her against her will while continuing to hold the knife. He warned her not to tell anyone, then fled the scene.
5. October 1, 1994 (morning): Complainant reported the rape to the Barangay Captain and to the local police.
6. October 3, 1994: Complainant underwent a physical and medical examination by Dr. Ernesto Calipayan. The medical report revealed that her private parts showed no signs of traumatic injury, and the microscopic examination of the cervical and vaginal smear was negative for spermatozoa. (Dr. Calipayan later explained that human spermatozoa survive only 48 to 72 hours, and the examination occurred more than 48 hours after the commission of the offense).
7. October 4, 1994: A formal criminal complaint for Rape was filed against appellant Roneto Degamo before the Regional Trial Court (RTC) of Ormoc City, Branch 12.
8. November 8, 1994: Due to severe and worsening psychological trauma, complainant was brought by her family to psychiatrist Dr. Gemelina Cerro-Go in Tacloban City. Dr. Go diagnosed complainant as suffering from acute and chronic psychosis (insanity) induced by the overwhelming trauma secondary to the rape.
9. December 15, 1994 and January 3, 1995: Complainant underwent psychiatric sessions with Dr. Go, who prescribed anti-psychotic drugs, low-acting tranquilizer injections, anti-depressants, and oral tablets.
10. Arraignment [Date NOT IN RECORD]: Prior to January 17, 1995, appellant Roneto Degamo was arraigned under the original complaint and entered a plea of not guilty.
11. January 17, 1995: Before the trial proper commenced, the prosecution filed a motion to amend the complaint to include the qualifying circumstance of the victim's resulting insanity under Article 335 of the RPC. The trial court granted the motion and admitted the Amended Complaint over the implicit silence of the defense.
12. Re-arraignment [Date NOT IN RECORD]: Following the admission of the Amended Complaint, appellant was re-arraigned and again entered a plea of not guilty.
13. February 16, 1995: During the trial, Dr. Gemelina Cerro-Go testified as an expert witness, declaring that the victim's psychosis was equivalent to insanity, that she had not fully recovered, and that she required continuous treatment for six months to five years to prevent regression.
14. May 22, 1995: The RTC rendered its Decision convicting appellant of qualified rape and sentencing him to suffer the penalty of Death.
15. April 30, 2003: The Supreme Court En Banc promulgated its Decision affirming the conviction and the death sentence, with modifications to the civil damages.

Arguments of the Parties

1. Procedural Sufficiency of the Amendment: The amendment of the complaint after the plea to include the allegation that "by reason of the incident of rape, the victim has become insane" is a purely formal amendment under Section 14, Rule 110 of the Rules of Court§. It does not alter the nature of the offense (which remains rape) or the prosecution's basic theory of the case, nor does it render the defense of denial unavailable.
2. Supervening Event Justification: The resulting insanity of the victim was clinically diagnosed only after the filing of the original complaint. It is akin to a supervening event because mental trauma is not immediately discernible and requires psychiatric observation before a conclusive diagnosis of psychosis can be made.
3. Waiver of Procedural Objection: The appellant failed to raise any objection to the amendment at the time the prosecution moved to amend the complaint, nor did he object during his re-arraignment or the trial proper, thereby waiving any right to challenge the amendment on appeal.

1. Prejudice to Substantial Rights: The post-arraignment amendment is a substantial amendment that violates the accused's constitutional right to be informed of the nature and cause of the accusation against him. The insertion of the insanity qualification escalated the penalty from a discretionary range (reclusion perpetua to death) under simple rape with a deadly weapon to a mandatory death sentence, severely prejudicing his defense.
2. Factual Improbability and Consensuality: The accusation is fabricated. Complainant and appellant were lovers who had engaged in consensual sexual relations on five different occasions. Complainant fabricated the rape charge out of fear that her husband's relatives would discover her infidelity.
3. Discrepancies and Insufficiency of Evidence: The prosecution failed to establish rape beyond reasonable doubt because:
   • (a) The complainant contradicted herself on whether she voluntarily opened the door for appellant;
   • (b) The medical examination showed no vaginal lacerations and was completely negative for semen;
   • (c) The prosecution failed to present the alleged deadly weapon (knife) in evidence; and
   • (d) The complainant was not genuinely insane because she gave coherent and intelligent answers on the witness stand during the trial.

• NOT IN RECORD (No stipulations of fact were entered by the parties).

Issue

1. Whether the non-presentation of the physical weapon (knife) used in the commission of the crime is fatal to a conviction for rape with a deadly weapon.
2. Whether the absence of physical traumatic injury on the victim's genitalia and the negative microscopic findings of spermatozoa in the medical examination preclude a conviction for rape.
3. Whether a temporary or treatable mental disorder (psychosis) induced by trauma falls within the statutory scope of the qualifying circumstance "has become insane" by reason or on the occasion of rape under Article 335 of the Revised Penal Code, as amended by Republic Act No. 7659.

Ruling

1. On the Main Issue: NO. The trial court did not err in admitting the Amended Complaint. The amendment is purely formal, did not prejudice the substantial rights of the appellant, and is equivalent to a supervening event.
2. On the first Secondary Issue: NO. The non-presentation of the weapon is not fatal. The credible testimony of the victim is sufficient to establish that a deadly weapon was used.
3. On the second Secondary Issue: NO. Traumatic injury and the presence of semen are not indispensable elements of rape, especially where the victim submitted due to fear for her life.
4. On the third Secondary Issue: YES. Under rules of statutory construction, the degree of insanity (whether permanent or temporary) is irrelevant under Article 335 of the RPC.

"WHEREFORE, the judgment of the lower court convicting appellant Roneto Degamo alias "Roy" of qualified rape and sentencing him to suffer the penalty of DEATH is AFFIRMED with the MODIFICATION that appellant is ordered to pay complainant Ellen Vertudazo the amounts of Seventy-Five Thousand Pesos (P75,000.00), as civil indemnity; Fifty Thousand Pesos (P50,000.00), as moral damages; Twenty-Five Thousand Pesos (P25,000.00) as exemplary damages; and Twenty-Five Thousand Pesos (P25,000.00) as temperate damages. Costs against appellant."

Ratio

1. Substantial Amendment defined: A substantial amendment consists of a recital of facts constituting the offense charged and determinative of the jurisdiction of the court. All other matters are merely of form.
2. Formal Amendments categorized: The Court held that the following are merely formal:
   • New allegations which relate only to the range of the penalty that the court might impose in the event of conviction;
   • An amendment which does not charge another offense different or distinct from that charged in the original one;
   • Additional allegations which do not alter the prosecution's theory of the case so as to cause surprise to the accused and affect the form of defense he has or will assume; and
   • An amendment which does not adversely affect any substantial right of the accused, such as his right to invoke prescription.
3. Prejudice Test: The test as to whether an amendment is only of form and does not prejudice the accused is:

   "whether or not a defense under the information as it originally stood would be equally available after the amendment is made, and whether or not any evidence which the accused might have would be equally applicable to the information in one form as in the other; if the answer is in the affirmative, the amendment is one of form and not of substance."

1. It did not charge another offense; the crime remained rape under Article 335.
2. It merely related to the range of the penalty (authorizing the death penalty).
3. The appellant's defenses of denial and consent ("illicit love affair") under the original Information remained equally available and applicable to the Amended Information.
4. The evidence of the defense was not rendered inapplicable.

• Insanity is a clinical and psychiatric condition that is not always readily discernible immediately after the commission of the crime.
• It may take weeks or even months of psychiatric observation and treatment before a medical expert can conclusively diagnose the victim with post-traumatic psychosis.
• Under these unique circumstances, the clinical diagnosis of insanity after the filing of the original complaint is legally treated as a supervening event. Thus, the corresponding amendment is procedurally valid and does not offend the double jeopardy clause.

"Objection to the amendment of an information or complaint must be raised at the time the amendment is made, otherwise, silence would be deemed a consent to said amendment."

1. Legislative Intent: The primary duty of the court is to determine legislative intent from the language of the statute, utilizing legislative history as an extrinsic aid.
2. Legislative History: The Court reviewed the history of Republic Act No. 2632 (the first amendment to Article 335 of the RPC that introduced the insanity qualification). The Congressional Records show that while Senator Pedro Sabido originally proposed the term "perpetual incapacity or insanity," the legislature deliberately deleted the word "perpetual" and retained only "insanity."
3. Doctrine of No Distinction: It is a settled rule of statutory construction that:

   "the courts should not interject a condition, make a distinction, or impose any limitation where the legislators did not opt to do so."

1. Weapon Non-Presentation: The non-presentation of the physical weapon is not fatal. The credible testimony of the rape victim that the accused was armed with a deadly weapon is sufficient to establish that qualifying circumstance beyond reasonable doubt.
2. Vaginal Trauma & Semen: The absence of spermatozoa or physical lacerations does not disprove rape. A woman threatened with death by a knife cannot be expected to exert a degree of physical resistance that would produce traumatic vaginal injury, and spermatozoa can naturally degrade or fail to be recovered if the medical examination occurs more than 48 to 72 hours after the crime.

Separate Opinions

• Three Unnamed Members of the Court maintained their position that Republic Act No. 7659, insofar as it prescribes the death penalty, is unconstitutional. However, they submitted to the majority ruling that the law is constitutional and concurred in the imposition of the death penalty on the appellant.
