What Are the Criminal Consequences of Falsifying Medical Certificates?
Introduction
Falsifying a medical certificate can result in criminal prosecution even when the document is intended only to obtain a personal advantage, such as leave, school exemption, employment accommodation, or access to a benefit. Philippine law separately punishes the private person who falsifies a medical certificate and the person who knowingly uses a false certificate.
The principal provisions are Article 174 of the Revised Penal Code, as amended by R.A. No. 10951, and Article 175 of the Revised Penal Code. The applicable offense depends on whether the accused created or altered the certificate, merely used it, or performed both acts.
What Law Applies to Private Persons?
Article 174 of the Revised Penal Code specifically covers false medical certificates. It imposes a penalty on three categories of offenders: physicians or surgeons who issue false certificates in connection with their profession; public officers who issue false certificates of merit or service; and private persons who falsify certificates within the classes covered by the provision.
Under the last paragraph of Article 174, a private person who falsifies a medical certificate may be punished by arresto mayor. R.A. No. 10951 amended Article 174 and increased the applicable fine for physicians and public officers to a fine not exceeding P200,000, but the amendment retained the penalty of arresto mayor for a private person who falsifies a covered certificate.
The governing provisions are [The Revised Penal Code (1930)](#L1.178) and [R.A. No. 10951 (2017)](#L2.25).
What Acts Constitute Falsification?
For a private person, falsification may include fabricating a medical certificate, altering an authentic certificate, inserting false medical findings, changing the date or period of incapacity, or making it appear that a physician issued or signed a certificate when the physician did not do so.
The prosecution must establish that the accused performed a falsifying act covered by the law and that the document falls within the class of certificates contemplated by Article 174. A document that merely contains an error is not automatically criminally falsified. The circumstances must show that the document was deliberately made false or was altered in a manner prohibited by law.
Where the charge is instead based on falsification of a private document under Article 172, the prosecution must generally prove damage to a third person or intent to cause such damage. [Malabanan v. Sandiganbayan, G.R. No. 186329, 2017](#J4.16) explains that the elements of falsification under Article 172, paragraph 2, include falsification of a private document and damage or intent to cause damage to a third person.
Is Personal Advantage Enough to Establish Liability?
Personal advantage by itself does not replace the elements of the offense. The fact that a person wanted to obtain sick leave, avoid work, pass a school requirement, qualify for a benefit, or obtain another accommodation may help prove motive or intent, but the prosecution must still prove the specific falsifying act and the required circumstances under Article 174.
Article 174 is directed at the falsification of a covered certificate. It does not require the prosecution to prove that the accused actually obtained the intended benefit before criminal liability may arise. Conversely, an unsuccessful attempt to obtain the benefit does not necessarily prevent prosecution if the falsification itself is complete.
Falsifying a Certificate Versus Using One
The Revised Penal Code distinguishes the person who falsifies a certificate from the person who knowingly uses one. Article 174 punishes a private person who falsifies the certificate. Article 175 punishes anyone who knowingly uses a false certificate mentioned in Article 174.
| Conduct | Potential provision | Important requirement |
|---|---|---|
| Creating or altering a false medical certificate | Article 174, Revised Penal Code | The accused must have falsified a certificate covered by the provision. |
| Knowingly presenting or relying on a false medical certificate | Article 175, Revised Penal Code | The accused must know that the certificate is false. |
| Falsifying and later submitting the same certificate | Possible liability under Articles 174 and 175, subject to the Information and the facts proved | The prosecution must properly charge and prove each alleged offense. |
Article 175 provides that a person who knowingly uses a false certificate covered by Article 174 is punished by arresto menor. Mere possession may be insufficient unless the circumstances show knowing use, attempted use, or another legally relevant act.
In [Brisenio v. People of the Philippines, G.R. No. 241336, 2021](#J1.7), the Supreme Court recognized the evidentiary principle that possession and use of a forged document may support the inference that the possessor was the forger when the accused fails to provide a satisfactory explanation. That inference is rebuttable and does not dispense with the prosecution’s obligation to prove guilt beyond reasonable doubt.
What Must the Prosecution Prove?
In a prosecution against a private person for falsifying a medical certificate under Article 174, the prosecution should establish the following matters:
- The accused is a private person who is not being prosecuted under the provisions applicable specifically to physicians or public officers.
- The document is a medical certificate or another certificate within the scope of Article 174.
- The accused falsified the certificate by fabricating, altering, or otherwise making it falsely appear authentic or truthful.
- The act was intentional and was not merely the result of clerical error, misunderstanding, or accidental alteration.
If the charge is for using a false certificate under Article 175, the prosecution must additionally show that the accused knowingly used the certificate. A person who innocently receives a false certificate without knowing its falsity may contest the required criminal intent.
Can the Accused Be Charged Even Without Actual Damage?
Yes, depending on the offense charged. Article 174 focuses on the falsification of a covered certificate, while Article 175 focuses on the knowing use of that false certificate. Actual financial loss or successful receipt of a benefit is not necessarily an element of either offense.
This differs from the second paragraph of Article 172, which expressly refers to damage or intent to cause damage when the falsification is committed in a private document. The precise statutory provision alleged in the Information therefore matters.
In falsification of public documents, the Supreme Court has stated that intent to gain or injure another is generally immaterial because the law protects public faith and the truthfulness of public records. [Mamaongpong v. Praxedes, G.R. No. 278545, 2023](#J2.1). That doctrine should not be mechanically applied to every certificate case; the classification of the document and the specific charge remain determinative.
Typical Examples
A private employee who edits a genuine medical certificate to extend the period of rest may face prosecution for falsification under Article 174. The fact that the employee sought only additional leave does not, by itself, remove the act from the scope of the provision.
A student who did not create the certificate but knowingly submits a fabricated medical certificate to excuse an absence may face liability under Article 175. The central issue would be whether the student knew that the certificate was false when it was submitted.
A person who obtains a certificate from a physician but changes the physician’s findings, signature, or dates may be treated differently from a person who merely submits the document without participating in its falsification. The evidence must identify each accused’s particular act.
Importance of the Information and Evidence
The accused cannot be convicted of an offense that was not properly alleged in the Information or that is not necessarily included in the offense charged. [Malabanan v. Sandiganbayan, G.R. No. 186329, 2017](#J4.16) emphasizes the constitutional right to be informed of the nature and cause of the accusation.
The prosecution should preserve the original certificate, the allegedly altered version, authentication or testimony from the issuing physician or facility, relevant electronic records, and evidence showing how the document was created or submitted. Screenshots or photocopies may require proper authentication and a satisfactory explanation of their source.
Where the authenticity of a signature or medical record is disputed, the defense may examine the issuing clinic’s records, appointment logs, electronic metadata, payment records, and testimony from the physician or clinic personnel. The absence of a genuine clinic record may be significant, but it must be evaluated together with the other evidence.
Possible Defenses and Issues
A defense may challenge whether the document is covered by Article 174, whether the accused personally falsified it, whether the accused knew it was false, or whether the prosecution proved the alleged act beyond reasonable doubt.
The defense may also argue that the alteration was accidental, that the accused relied in good faith on information supplied by another person, or that the accused did not know the certificate was false when it was used. These defenses depend on the documentary and testimonial evidence.
Intent is assessed from the surrounding circumstances. However, an accusation or suspicion alone is insufficient. In administrative proceedings involving alleged document falsification, the Supreme Court has likewise reiterated that charges must be supported by substantial evidence rather than mere allegations or suspicion. [In Re: Talaboc, A.C. No. 11889, 2024](#J6.1).
Penalty and Related Offenses
The private person who falsifies a medical certificate under Article 174 is subject to arresto mayor. A person who knowingly uses a false certificate under Article 175 is subject to arresto menor.
Other charges may arise if the false medical certificate is used as part of a broader scheme. For example, additional liability may be considered where the document is used to obtain money, property, or another benefit through deceit. The proper charge depends on the facts, the nature of the document, the victim’s loss, and the allegations in the Information.
The penalties and statutory text should be checked against the current law because R.A. No. 10951 amended several fines and monetary thresholds in the Revised Penal Code. Its amendment to Article 174 increased the fine applicable to physicians and public officers but retained arresto mayor for a private person who falsifies a covered certificate.
Practical Steps for Employers, Schools, and Individuals
- Verify questionable certificates directly with the issuing physician or medical facility, subject to privacy and authorization requirements.
- Preserve the original document, electronic file, submission record, and communications concerning its preparation or use.
- Do not publicly accuse the person of falsification before the evidence is assessed and appropriate legal advice is obtained.
- Identify whether the suspected conduct is falsification, knowing use, fraud, or another offense before preparing a complaint.
- For an accused person, obtain the original records and avoid altering, deleting, or communicating about potentially relevant evidence.
Conclusion
A private person who deliberately fabricates or alters a medical certificate may be prosecuted under Article 174 of the Revised Penal Code, as amended by R.A. No. 10951. A person who knowingly submits or uses a false certificate may separately face liability under Article 175.
Personal advantage, such as obtaining leave or avoiding an obligation, may explain the conduct but does not alone establish guilt. The decisive issues are the nature of the certificate, the accused’s specific act, knowledge and intent, the allegations in the Information, and whether the prosecution can prove every element beyond reasonable doubt.
Anyone handling a suspected falsified certificate should preserve the records, verify the document through proper channels, and seek advice before filing a criminal complaint or taking disciplinary action.
