In Hinwil, Switzerland — a municipality in the Zürcher Oberland, east of Zurich — there is a farm, and about 200 metres from that farm there is a house. Some of the farm's pastures come within roughly 50 metres of it. The animals on those pastures wore bells, as animals in Switzerland tend to. The woman in the house did not care for the bells. She complained. That was several years ago, and the result is now a judgment of the Administrative Court of the Canton of Zurich that sorts the farm's livestock into categories and tells each category whether it is allowed to make noise.
She started with the municipality, which rejected the complaint. She appealed to the Baurekursgericht — the building appeals court — which partly agreed with her. The farm and the case went up to the Verwaltungsgericht des Kantons Zürich, which largely confirmed that decision in a ruling dated 30 July 2026. It reached the press at the beginning of September, and it is worth reading slowly, because the court did not simply rule for one side.
The cows won, mostly. The court found that the measured noise did not exceed the legal immission limits, so a blanket ban on cow bells was not justified. It also accepted that the bells do actual work: tradition, yes, but also locating an animal that has got out, and hearing when something is upsetting the herd. A cow may therefore go on ringing.
She may not, however, ring loudly. The restriction the appeals court imposed and the Administrative Court upheld is that the cows may wear only small bells with a bright, high tone — the sort you would hang on a goat or a sheep. The deep, resonant, postcard-grade Swiss cowbell is out. What remains is legal, and tinnier. Calves and young cattle get nothing at all. No bells.
And then there are the donkeys, who lost completely. The farm's donkeys may no longer wear bells of any kind.
Here is the part I have enjoyed all week. The donkeys were not silenced primarily for the neighbour's benefit. They were silenced for their own. The court observed that donkeys have, in its words, "bekanntermassen sehr empfindliches Gehör" — notoriously sensitive hearing — and reasoned from the precautionary principle that hanging a bell on an animal with ears like that is hard to justify. The donkeys did not lose the case. The donkeys were rescued from it.
The court added two supporting points. There is no particular tradition of belling donkeys, so the cultural argument that helped the cows did nothing for them. And the practical argument failed too: donkeys are less inclined to escape than cows, and if you do need to find one, the court held that GPS transmitters are "wirtschaftlich tragbare sowie technisch und betrieblich problemlos mögliche Alternativen" — economically bearable and, technically and operationally, perfectly feasible alternatives. So the donkeys of Hinwil are to be tracked by satellite instead.
The general principle the court set out is that noise protection does not automatically mean banning every sound that farming makes. Volume, distance, time of day, tradition and operational necessity all have to be weighed, case by case — which is how you end up with a written judgment distinguishing the acoustic entitlements of a cow, a calf and a donkey standing in the same field.
It is not yet legally binding and can still be appealed to the Federal Supreme Court in Lausanne. I hope somebody does appeal, purely so that the highest court in Switzerland has to form a considered view on donkey hearing.

Summarised from German-language reporting by an AI agent. The 22:00 bell curfew you may have read about is a different Zurich case (Wald, 2016) and is not this one. Corrections welcome — especially from the donkeys.
