People vs. Quebral

The governing principle is that when a negative averment constitutes an essential element of a criminal offense, the burden of proof rests on the prosecution. Because proving a negative is inherently difficult, the prosecution discharges this burden by establishing a prima facie case through the best available evidence, after which the evidentiary burden shifts to the accused to prove the existence of the license or certificate. The Court applied this rule to uphold the conviction, finding that an official non-registration certificate and the accused’s own correspondence sufficiently established the statutory element.

In June 1937, the provincial fiscal of Pangasinan filed an information charging Fernando C. Quebral with the illegal practice of medicine from 1930 to May 1937 across several municipalities without securing a certificate of registration from the Board of Medical Examiners, in violation of Section 770 of the Revised Administrative Code. The prosecution established that the accused diagnosed, treated, and prescribed for patients in exchange for compensation. The trial court found that the acts constituted the practice of medicine but ruled that the burden to prove registration rested on the accused, resulting in conviction and a P200 fine. The accused appealed, contesting the allocation of the burden of proof and the sufficiency of the evidence regarding his lack of a medical certificate.

• The accused, Fernando C. Quebral, diagnosed, treated, and prescribed for various patients between 1930 and May 1937 in multiple municipalities within Pangasinan, receiving monetary compensation for his services.
• The prosecution charged Quebral with violating Section 770 of the Revised Administrative Code, which prohibits practicing medicine without a prior certificate of registration issued by the Board of Medical Examiners.
• The trial court found that the accused’s acts constituted the practice of medicine but held that the burden to prove registration rested on the accused, citing prior jurisprudence and procedural rules.
• The trial court convicted Quebral and imposed a fine of P200. On appeal, Quebral maintained that the prosecution failed to prove he lacked a valid medical certificate.
• During trial, the prosecution introduced Exhibit F-2, a certification signed by the Chairman of the Board of Medical Examiners stating that diligent search of the Board’s records revealed no registration for Quebral.
• The prosecution also introduced Exhibit H-3, a letter written by Quebral to the President of the Philippines, which quoted a newspaper article confirming that he did not hold a degree in medicine.
• The trial court relied on Exhibits F-2 and H-3 to establish the absence of a registration certificate and affirmed the conviction.

• Defendant-Appellant Quebral maintained that the prosecution bore the burden to prove the negative averment that he practiced medicine without the proper certificate of registration.
• He argued that the prosecution failed to adduce direct evidence of his non-registration, and under the presumption of innocence, the absence of such proof warranted acquittal.
• He contended that the trial court improperly shifted the burden of proof to him by requiring him to affirmatively demonstrate his registration status.

• The People, as appellee, contended that the negative averment regarding non-registration was a matter of defense, thereby placing the burden of proof on the accused to establish his lawful registration.
• Alternatively, the People argued that the prosecution satisfied its evidentiary obligation by presenting official board records and the accused’s own correspondence, which collectively established a prima facie case of unlicensed practice.

• Procedural Issues: Whether the prosecution bears the burden of proving the negative averment of non-registration, or whether the burden shifts to the accused to prove registration as an affirmative defense.
• Substantive Issues: Whether the evidence presented by the prosecution, specifically an official non-registration certification and the accused’s own letter, sufficiently established the essential element of practicing medicine without a valid certificate under Section 770 of the Administrative Code.

• Procedural: The Court held that the prosecution bears the burden of proving the negative averment when it constitutes an essential element of the offense. Because proving a negative is inherently difficult, the prosecution need only establish a prima facie case through the best available evidence, which shifts the evidentiary burden to the accused to produce contrary proof.
• Substantive: The Court found that Section 770 explicitly makes the want of a certificate an inseparable element of the offense, requiring the prosecution to prove it. The Court ruled that Exhibit F-2, an official certification from the Board of Medical Examiners attesting to the absence of the accused’s name in the registry, and Exhibit H-3, the accused’s own letter acknowledging he lacked a medical degree, constituted sufficient prima facie evidence. Accordingly, the prosecution discharged its burden, and the conviction was affirmed.

• Burden of Proving Negative Averments in Criminal Cases — When a negative fact is an essential ingredient of a statutory offense, the prosecution must prove it. However, because proving a negative is practically difficult, the prosecution satisfies this burden by presenting prima facie evidence, which shifts the burden of production to the defense. The Court applied this doctrine to the crime of illegal medical practice, holding that an official certification of non-registration and the accused’s own admission sufficiently established the negative element, thereby sustaining the conviction.

• "The rule, however, is different when the subject of the negative averment does not constitute an essential element of the offense, but is purely a matter of defense. In such case, the burden of proof is upon the defendant." — The Court articulated the distinction between negative elements of a crime and affirmative defenses to clarify the proper allocation of the burden of proof.
• "The certificate of a custodian that he has diligently searched for a document or an entry of a specified tenor and has been unable to find it ought to be usually as satisfactory for evidencing its non-existence in his office as his testimony on the stand to this effect would be." — The Court relied on this evidentiary principle to admit the Board Chairman’s certification as an exception to the hearsay rule, validating it as competent proof of non-registration.

• U.S. v. Tria, 17 Phil. 303 — Cited as controlling precedent for the rule that when a negative averment inheres in the offense, the prosecution bears the burden of proof but may satisfy it by establishing a prima facie case due to the inherent difficulty of proving a negative.
• U.S. v. Chan Toco, 12 Phil. 262 — Cited to delineate the boundary between negative averments that form essential elements of a crime and those that operate solely as matters of defense.
• U.S. v. Gonzalez, 10 Phil. 67; U.S. v. Co Pinco, 10 Phil. 370; U.S. v. De la Torre, 42 Phil. 65 — Referenced to illustrate established jurisprudence on the allocation of the burden of proof regarding professional registration and statutory negative requirements.

• Section 770, Revised Administrative Code — Prohibits the practice of medicine without a prior certificate of registration. The Court held that the absence of such a certificate is an essential element of the offense, mandating prosecution to prove it.
• Section 297, Code of Civil Procedure — Referenced regarding the general rule on the burden of proof and the prosecution’s obligation to establish each element of the charged offense beyond reasonable doubt.
