1. Introduction

Threat messages, whether via SMS, messaging applications, or voice calls from unknown numbers, can be intimidating and cause distress. Under Philippine law, such communications may constitute criminal offenses. This article will outline:

The primary laws relevant to threat messages in the Philippines.
The classifications of threats under the Revised Penal Code.
The procedures for filing complaints and gathering evidence.
Additional remedies and protective measures.

2. Relevant Laws in the Philippines

2.1 Revised Penal Code (RPC)

Grave Threats (Article 282): A person commits grave threats when they threaten another with a wrong amounting to a crime (e.g., threats of serious physical harm or death). Punishments vary depending on the severity of the threat.
Light Threats (Article 283): Threatening to cause harm or wrong not amounting to a crime but still causing alarm or fear in the person threatened.
Other Related Provisions: Acts that cause anxiety, fear, or distress may fall under other provisions depending on the specifics (e.g., “other light threats” or “unjust vexation,” although “unjust vexation” typically covers acts of annoyance rather than direct threats).

2.2 Cybercrime Prevention Act of 2012 (Republic Act No. 10175)

If the threat is sent electronically (through text messages, instant messaging apps, email, or social media), it can fall under offenses penalized by RA 10175 if it involves illegal access, identity theft, cyberstalking, or other forms of cyber harassment.
Under RA 10175, law enforcement agencies such as the Cybercrime divisions of the Philippine National Police (PNP) or National Bureau of Investigation (NBI) have the authority to investigate and gather digital evidence related to cyber threats.

2.3 Safe Spaces Act (Republic Act No. 11313)

Primarily aimed at addressing gender-based sexual harassment in public spaces, online spaces, workplaces, and educational institutions. If a threat is accompanied by sexual harassment or gender-based violence (e.g., repeated harassing or threatening sexual messages), the Safe Spaces Act may apply.

2.4 Other Potentially Applicable Laws

Anti-Photo and Video Voyeurism Act (RA 9995), if the threat messages involve sharing intimate images without consent.
Anti-Bullying Law (RA 10627), if the threats involve minors and are part of bullying behavior in schools, though usually handled in educational institutions rather than criminal courts.

3. Classification of Threats

3.1 Grave Threats

Definition: Threatening another with the infliction of a crime (e.g., murder, serious physical harm, kidnapping).
Penalty: The penalty varies, but can include imprisonment (known as prisión mayor or prisión correccional) depending on the nature and seriousness of the threat.

3.2 Light Threats

Definition: Threatening another with harm that does not constitute a crime but still causes fear or alarm (e.g., minor property damage, minimal physical harm).
Penalty: Typically lower than grave threats (often arresto menor or arresto mayor).

3.3 Unjust Vexation

Sometimes, messages that do not directly threaten but cause repeated harassment, annoyance, or disturbance could be treated under “Unjust Vexation” (Article 287 of the RPC). While less severe than actual threats, it can still be a basis for complaint.

4. Practical Steps if You Receive Threat Messages

Stay Calm and Do Not Engage
- Refrain from responding to the unknown number. Engaging might provoke further threats or harassment.
Preserve All Evidence
- Take screenshots of the messages, including timestamps, sender’s number, or any sender ID information.
- If they are voice messages or calls, record the call times and keep relevant voice logs where possible.
Report to Law Enforcement
- Philippine National Police (PNP) Cybercrime Unit: You can file a complaint and submit the evidence you have collected.
- National Bureau of Investigation (NBI) Cybercrime Division: Particularly if the threat persists or escalates, or if you believe the threat might be part of a larger crime (e.g., extortion, blackmail).
Coordinate with Your Telecommunications Provider
- Some threats can be traced back if the SIM registration details are accurate. However, the enforcement of the SIM Card Registration Act is still evolving. Law enforcement typically must coordinate with the telecom service provider to obtain subscriber information or call data records, subject to compliance with privacy laws and court orders.
Seek Legal Counsel
- Consult with a lawyer to help you evaluate the nature of the threats and determine which legal remedies fit your situation.
- A lawyer can also help you prepare sworn statements or affidavits needed for the case.
File a Complaint or Case
- Depending on the type of threat, you may file a criminal complaint for Grave Threats, Light Threats, or Unjust Vexation under the Revised Penal Code.
- If the threat involves cyber elements—such as repeated harassment through SMS, chat apps, or social media—cite RA 10175 in your complaint.
- For gender-based harassment or sexual threats, you may invoke the Safe Spaces Act.

5. Legal Remedies and Court Procedures

5.1 Preliminary Investigation

After you file a complaint with the prosecutor’s office or law enforcement, the complaint undergoes preliminary investigation. The prosecutor determines if there is probable cause to file the case in court.

5.2 Filing of Information in Court

If probable cause is found, the prosecutor files the Information in the appropriate Regional Trial Court (RTC). For less serious offenses (light threats), it could be under the jurisdiction of the Municipal Trial Court (MTC).

5.3 Trial Proper

The accused will be arraigned, and the trial process commences. You, as the complainant, may need to provide testimony and evidence.
The court will then decide whether the accused is guilty beyond reasonable doubt and impose the corresponding penalty under the RPC or other applicable laws.

5.4 Civil Remedies

You may also have the option to file a separate civil action for damages if you have suffered mental anguish, anxiety, or any other form of harm. The threat must have caused tangible or provable harm for civil damages to be awarded.

6. Protective Measures and Other Considerations

Temporary Protection Orders (TPOs)
- If the person sending threats is known or can be identified, and there is a danger of physical harm (especially in cases of domestic abuse or gender-based violence), you may apply for a TPO under the Anti-Violence Against Women and Their Children Act (RA 9262) or Safe Spaces Act (RA 11313) if applicable.
Law Enforcement Assistance
- In cases of imminent physical harm, request police patrols in your area or coordinate with barangay officials to keep an eye on your safety.
Digital Security
- Change privacy settings on social media if the threats extend beyond phone messages.
- Consider using call-blocking or message-filtering functions.
- Report the threatening account or number through the respective platform (e.g., Facebook, Viber, WhatsApp) if applicable.
Mental Health Support
- Threats can be distressing. If necessary, seek psychological support or counseling. Some organizations and community centers offer free or low-cost mental health resources.

7. Frequently Asked Questions

What if the sender’s phone number is not registered or is a prepaid SIM?
- Under the SIM Card Registration Act (RA 11934), all SIM cards are required to be registered. However, enforcement is ongoing. Law enforcement may still be able to track the number by coordinating with the telecom provider, although it can be more challenging with unregistered or fraudulently registered SIMs.
How long can I wait before reporting to the police?
- It’s best to report immediately to preserve evidence and increase the chances of tracing the sender. However, even if you delay, you can still file a complaint as long as you are within the prescriptive periods for criminal offenses.
Can I apply for a restraining order if I don’t know who is sending the threats?
- Generally, you need to identify the respondent for a restraining order to be effective. If the identity of the threat sender is unknown, your primary recourse is to work with law enforcement to uncover their identity.
What if the threats are directed at my family or property?
- The same provisions on Grave Threats or Light Threats can apply. Document all messages and file a complaint on behalf of the threatened parties, especially if minors are involved.
Is mediation possible if I discover who is threatening me?
- In some cases, amicable settlement may be explored, but serious threats (e.g., grave threats) often proceed in the criminal justice system due to public policy concerns. A lawyer can advise on whether mediation is an option.

8. Conclusion

Receiving threat messages from unknown numbers can be alarming, but Philippine law offers multiple remedies to address and penalize such actions. Key steps include preserving evidence, consulting law enforcement and legal counsel, and, if necessary, filing a criminal complaint. While cyber elements may complicate the process, the Cybercrime Prevention Act of 2012 strengthens the ability of the PNP and NBI to investigate and prosecute individuals who use electronic communications to threaten or harass others.
