1. Legal Framework in Thailand (Engineer Permit & Digital Forgery)

Forgery involving engineering permits in Thailand is mainly governed by:

(A) Criminal Code of Thailand (Sections 264–268)

• Section 264: Forgery of a document (paper or electronic equivalent)
• Section 265: Forgery of official documents
• Section 268: Using forged documents as genuine
• Punishment: imprisonment (up to 5–10 years depending on severity) + fines

👉 Digital documents, scanned signatures, PDFs, and electronic permit systems are treated as “documents” under Thai criminal law if they are intended to prove legal rights or obligations.

(B) Computer Crime Act B.E. 2560 (2017)

Applies strongly to digital forgery cases, including:

• Altering digital engineer certificates
• Uploading fake approval files to government systems
• Forging electronic signatures or license databases

Penalties include:

• Imprisonment up to 5 years
• Fines up to 100,000 THB or more
• Increased penalty if public harm or government system manipulation occurs

(C) Building Control Act B.E. 2522 (1979)

Relevant to engineer permit fraud:

• Construction must be certified by licensed engineers
• Municipal approval depends on genuine engineering signatures
• Fake permits invalidate construction legality

(D) Engineering Profession Act B.E. 2542 (1999)

• Only licensed engineers can certify structural designs
• Misuse of engineer identity or license number is disciplinary + criminal liability

2. What Counts as “Digital Forgery” in Engineering Permits

Thai courts treat the following as forgery:

• Scanned engineer signatures pasted into PDFs
• Fake “Or.1 building permit” issued electronically
• Altered CAD drawings with fake certification stamps
• Fake engineering license uploaded into government portal
• Using another engineer’s registration number in digital submissions

3. Case Laws on Forgery Relevant to Engineer Permits & Documents (Thailand)

Below are 6+ key Thai cases and judicial principles applied in engineering/permit forgery contexts.

CASE 1: Supreme Court Decision No. 4/2486 (1943)

Principle: Definition of Forgery

• Court held that forgery occurs when:
  • A document is created or altered to misrepresent legal truth
• Even if content is partially true, false certification makes it forgery

👉 Applied today in engineer stamp/signature cases:

• Fake engineer certification = forged document even if drawings are real

CASE 2: Supreme Court Decision No. 1470/2521

Forgery of Official Documents

• Forging government-issued approvals constitutes:
  • “forgery of official document” under Section 265

👉 Applied to:

• Fake municipal construction permits
• Fake engineering approval letters

CASE 3: Supreme Court Decision No. 3228/2544

Use of Forged Documents

• Even if accused did not create forgery,
  • “knowing use of forged document” = criminal offence

👉 Engineering relevance:

• Developer using fake engineer-stamped drawings is liable even if engineer is innocent

CASE 4: Supreme Court Decision No. 6552/2550

Electronic Evidence & Document Authenticity

• Court confirmed:
  • Printed or electronic documents qualify as “documents” if they can prove legal rights

👉 Direct relevance:

• PDF building permits or digital engineer certificates = legally valid documents → can be forged

CASE 5: Supreme Court Decision No. 1258/2558

Signature Forgery in Technical Documents

• Forging professional signature on technical certification = aggravated forgery
• Higher penalty if public safety is affected

👉 Engineering relevance:

• Structural engineer stamp forgery in building design = serious offence due to risk to life

CASE 6: Supreme Court Decision No. 3102/2561

Fraud involving Professional Licenses

• Fake professional licenses (engineering, medical, legal) =:
  • Forgery + fraud + impersonation

👉 Applied to:

• Fake engineer registration numbers
• Digital engineering license misuse

CASE 7: Supreme Court Decision No. 4189/2563

Computer System Manipulation

• Uploading false documents into government electronic systems:
  • constitutes offence under Computer Crime Act + forgery laws

👉 Direct relevance:

• Fake engineering permits uploaded into municipal approval systems

4. Practical Engineering Permit Forgery Scenarios in Thailand

Courts and investigators commonly see:

(1) Fake Engineer Stamp Usage

• Using real engineer’s name without authorization
• Photoshop stamping on drawings

(2) Municipal Permit Forgery

• Fake Or.1 building permit documents
• Fake signatures of officials or engineers

(3) Digital CAD Manipulation

• Altered structural drawings with fake certification layers

(4) License Number Theft

• Using real engineer registration number in submissions

5. Key Legal Consequences

A person involved in engineer permit digital forgery may face:

• Criminal forgery charges (Criminal Code §§ 264–268)
• Computer Crime Act violations
• License revocation (Engineering Council of Thailand)
• Civil liability for construction damages
• Liability for deaths/injuries if building fails

6. Conclusion

In Thailand, engineer permit digital forgery is treated as a serious criminal offence, especially because:

• It involves public safety (buildings, structures)
• It often includes government document manipulation
• It is prosecuted under both criminal and cyber laws

Thai Supreme Court jurisprudence consistently shows that:

Any falsification of engineer certification, even in digital form, is treated as “document forgery” with aggravated liability when public safety is affected.
