What happened
A fire at the Ozone Disco in Quezon City in 1996 killed 162 people, many of them students celebrating the end of the school year.
The investigation
Investigations focused on overcrowding, exit design, fire-safety violations and failures in the inspection and permitting process.
What the courts or investigators concluded
Years of litigation eventually produced convictions of club officials and public employees for offenses connected to the unsafe conditions and approvals.
Why the case remains significant
The disaster remains one of the deadliest nightclub fires in history and a Philippine reference point for why occupancy limits, outward-opening exits and meaningful fire inspections matter.
