Municipal authorities considering pyrotechnics permits under a Veracruz noise law must assess the potential health effects on children and adolescents on the autism spectrum, particularly where sound sensitivity is involved, Mexico’s Supreme Court has ruled.
The ruling arose from a request by the mother of a girl with autism and hyperacusis, a condition involving heightened sensitivity to certain sounds. She had asked a municipal authority in Veracruz to take steps to raise awareness about pyrotechnics and regulate their use after excessive detonations in her locality affected her daughter’s health and wellbeing, as well as other people on the autism spectrum.
The municipal council responded by recommending that residents use pyrotechnics only during the hours set out in the state’s Noise Law, from 6am to 11pm. The mother brought an amparo case, arguing that the response was insufficient and that the legal provision did not adequately protect disabled people. A district court granted protection in relation to the municipal response but not the provision itself. The review then reached the Supreme Court.
A licence is not automatic permission
The Supreme Court upheld Article 10 of the Veracruz law, but only through an interpretation that places concrete duties on municipal licensing decisions. The provision regulates the hours for pyrotechnics use and requires a municipal licence. The judgment makes clear that compliance with the permitted hours is not, by itself, enough to justify an approval.
Before a licence is granted, the authority must examine the kind and quantity of pyrotechnics proposed, their sound intensity, the location and timing of their use, and the possible effects on the health of people on the autism spectrum. That assessment is especially important where children or adolescents could be affected and have sound sensitivity.
If an authority identifies a risk to health which cannot be prevented by an available measure, it cannot issue the licence. The ruling therefore requires a decision based on the particular event and its likely effects, rather than an automatic approval for a traditional celebration or for an event scheduled within the statutory hours.
What the judgment changes
The decision does not impose a general prohibition on fireworks or declare that all traditional celebrations must end. It keeps the Veracruz provision in force while requiring municipal authorities to apply it in a way that protects health, inclusion and the best interests of disabled children.
Nor does the ruling state that every autistic person will experience sound in the same way. Its focus is on the differentiated effects that intense sounds can have on people on the autism spectrum who have hyperacusis or comparable sound sensitivity. That distinction matters because a permit decision must address actual potential harm, not make assumptions about an entire group of people.
The Court framed the issue through the social model of disability, which requires public authorities to identify and remove barriers in the environment that prevent equal participation. In this case, the relevant barrier may be the intensity, timing or setting of a proposed pyrotechnic display. The task for the licensing authority is to consider whether changes can prevent harm before deciding whether permission can be granted.
A local case with wider practical significance
The immediate legal issue concerned a Veracruz statute and its municipal-licensing requirement. The ruling does not set a universal decibel limit or announce a nationwide permit scheme. It does, however, set out a clear test for decisions made under the law examined by the Court: a permitted time window cannot displace the duty to consider health risks to disabled children and young people.
For organisers, municipal officials and families in the places governed by that framework, the practical consequence is that event details now matter directly to a licensing decision. The type, scale, sound, site and timetable of a display must be considered alongside whether effective safeguards are available. Where they are not, the licence must be refused.
The ruling was made by the full Supreme Court on 28 October in Amparo en Revisión 73/2026. Its immediate result is a more demanding process for pyrotechnics licences under the Veracruz provision, while preserving the need to balance traditional events with the health and inclusion of people who may be affected by intense noise.
