AI Legal Research Grant

National Innovation Agency (NIA) — Ministry of Higher Education, Science, Research and Innovation

KEY FINDINGS

What the Data Reveals

AI analysis of all 311 ordinances across 19 categories, spanning 53 years of Bangkok municipal legislation.

43%

Critically Outdated

135 ordinances are 30+ years old. Many predate BTS, smartphones, food delivery, and the modern economy they are supposed to regulate.

69%

Over 20 Years Old

Combined with high-risk ordinances (20-29 years), over two-thirds of Bangkok's legal framework was written for a fundamentally different city.

Overlapping Zoning Laws

74 separate ordinances regulate building zones across Bangkok — many conflicting with each other. These should be consolidated into a single unified urban planning code.

Digital-Era Ordinances

Zero ordinances address digital government, smart city infrastructure, data governance, or platform economy regulation. Bangkok's legal framework has no digital chapter.
