Case Law On Emerging Ai-Related Offenses Under Singapore Cybercrime Law
🧑‍⚖️ Singapore Legal Framework Addressing AI‑Related Offenses
Singapore’s legal system is not yet built around explicit “AI crime” statutes, but existing laws have been interpreted and applied to AI‑enabled misconduct or AI‑generated content harms. Key frameworks include:
1. Computer Misuse Act (CMA)
The CMA criminalizes unauthorized access and modification of computer systems and data.
If AI is used to bypass security, phish, or gain unauthorized access, the offender may be charged under CMA sections 3 (unauthorized access) or 5 (unauthorized modification).
Deepfake‑enabled frauds that secure access to data or systems can be charged under CMA as well.  ICLG Business Reports
2. Penal Code (Cheating, Defamation, and AI‑generated Impersonation)
Under the Penal Code:
Section 415 & 416 — cheating and cheating by personation: AI‑generated content that impersonates someone to deceive (e.g., make financial gains) can meet elements of fraud.
Section 499 & 500 — defamation: deepfakes attributing false statements to others can be defamatory.
Deepfakes or AI outputs used dishonestly can therefore attract regular criminal offenses like fraud and defamation even if no AI‑specific law exists. withersworldwide.com
3. Protection from Online Falsehoods and Manipulation Act (POFMA)
POFMA tackles the spread of false statements online. It can apply to AI‑generated misinformation and gives authorities powers to issue corrections or demand takedowns.
Publishing or enabling falsehoods that mislead the public can trigger enforcement actions under POFMA. Wikipedia
4. Emerging Legislation
The Criminal Law (Miscellaneous Amendments) Bill 2025 proposes new offenses related to intimate images created by AI and makes it an offense to produce or possess such images without consent. This expands the Penal Code to include AI‑generated intimate materials within statutory protections. withersworldwide.com
📌 Case Law and Judicial Responses Involving AI or AI‑Generated Content
While traditional appellate case law on AI crimes is still nascent in Singapore, there are recent judicial decisions and sanctions showing how courts are applying established laws to AI‑related conduct:
Case 1 — High Court Sanctions Lawyer for Citing AI‑Generated Fake Case (2025)
Core Facts:
A lawyer filed court submissions in a civil dispute citing a non‑existent legal authority that was generated by an AI tool and presented as real.
Judgment:
Assistant Registrar Tan Yu Qing held that citing a fake authority was a misuse of technology and an abuse of process. The lawyer was ordered to pay $800 personally to the opposing party for wasting judicial time.
Legal Significance:
Although this was not a criminal prosecution, the High Court treated the use of fabricated AI‑generated content seriously under court procedure rules.
The judge stressed that lawyers must independently verify AI outputs and cannot treat generative AI as a substitute for actual legal research. The Straits Times+1
Case 2 — Second AI Hallucination Case in Singapore Courts (2025)
Core Facts:
In another civil matter, parties’ submissions included entirely fictitious cases likely generated by AI. The High Court (Justice S Mohan) noted the danger of AI “hallucinations”—plausible but fabricated legal authorities.
Outcome:
The judge reserved judgment on sanctions, and the incident reinforced judicial expectations that AI outputs must be vetted.
Legal Significance:
Courts have begun to treat AI‑invented citations as improper conduct under procedural rules.
This signals that AI misuse can have adverse legal consequences even outside traditional criminal prosecutions. The Business Times
Case 3 — Application of CMA to AI‑Enabled Cyberattacks (Phishing Example, 2019)
Core Facts:
While not directly AI, the Public Prosecutor v Lim Yi Jie case shows how CMA enforcement works in online deception cases: a phishing site caused a victim to divulge secure credentials.
Legal Principle:
Under s.3 of the CMA (now amended), using technology—potentially including AI—to cause unauthorized access is criminal.
Relevance to AI:
If AI enhances phishing (e.g., generating highly personalized phishing messages), the same CMA provisions could capture such conduct. ICLG Business Reports
Case 4 — Misinformation and POFMA Enforcement (General Online Falsehoods)
Statutory Context:
POFMA has been used to counter falsehoods spread online. While no leading deepfake case has yet been publicized in Singapore under POFMA specifically for AI content, the Act expressly covers false statements communicated online, including via bots or synthetic media that have real‑world harms.
Legal Significance:
Publishing or facilitating false AI‑generated content aimed at influencing public opinion or causing harm can be restrained or sanctioned under POFMA. Wikipedia
Case 5 — Future Potential: AI Intimate Image Offenses (Criminal Law Amendments 2025)
Legislative Framework:
The Criminal Law (Miscellaneous Amendments) Bill 2025 expands the definition of “intimate image” to include AI‑generated material without consent.
Expected Criminal Consequences:
Producing or possessing non‑consensual AI‑generated intimate images will be a specific offense.
Penalties could include imprisonment and fines, aligning with broader Singapore laws against image abuse. withersworldwide.com
While this is a statutory development, not a decided case yet, it represents Singapore’s first explicit criminal law response uniquely tailored to AI misuse.

Deepfake, Harassment, and Defamation
AI‑generated deepfakes that harm reputation may be prosecuted under Penal Code defamation provisions or civilly actionable for damages and injunctions.
Deepfake pornography can trigger prosecution under the Films Act for possessing or distributing obscene content, even if AI‑generated. guardianlaw.com.sg
AI Content and Online Harms
The Protection from Harassment Act (POHA) may be invoked where AI‑generated content causes harassment, alarm, or distress.
Victims can seek protective orders or criminal charges. Nanyang Technological University
🧠Key Takeaways
Established Laws Are Being Used for AI Misuse.
Singapore courts apply the Computer Misuse Act, Penal Code, POFMA, and procedural rules to cases involving AI‑generated misconduct.
AI‑Generated Misconduct Can Lead to Legal Sanctions — Even Without AI‑Specific Laws.
Citing fabricated case law led to sanctions in court procedures.
Misrepresentation, fraud, and deception enabled by AI can be charged as cheating or unauthorized access.
New Legislation Is Emerging.
