"... The cause of the fire has not yet been established..." But, surely there is plenty of documentary evidence already available to rule things out of consideration? A venue licensed as a “restaurant” but producing a 34‑fatality fire should have had clear, routine compliance evidence of electrical safety inspections, LPG records, fire safety certifications, occupancy permits, and proof it was operating within its approved category. If those records are missing, falsified, or show the venue was actually functioning as a nightlife space, that’s not a paperwork glitch, it’s grounds for criminal charges. One would hope that, even under Thai law, the absence of required documentation is itself a violation, and operating outside approved use is a separate offence. So investigators should already be able to rule out certain causes, and if they can’t, that points to regulatory breaches long before the fire started.
