When the Law Gets Weird

Every country's legal code carries the sediment of its history. Laws are written in response to specific problems at specific moments in time, and when those moments pass, the laws sometimes don't. The result is a global collection of statutes that range from the mildly peculiar to the genuinely baffling — still technically on the books, still occasionally enforced, and always fascinating as windows into the cultures and concerns that created them.

Here is a tour of some of the world's most curious surviving laws — and what they can tell us about the societies that made them.

Singapore: No Chewing Gum (Almost)

Singapore banned the import and sale of chewing gum in 1992, a law so associated with the city-state that it has become a defining feature of its global reputation. The motivation was practical and very Singaporean: gum left on Mass Rapid Transit sensor pads was causing train door malfunctions. In a country that takes public cleanliness and infrastructure seriously, the solution was simply to remove the product.

The ban was partially relaxed in 2004, when sugarless, therapeutic gum was permitted to be sold by pharmacists — but only with a prescription. Casual gum-chewing remains effectively illegal, and the fines for importing gum for sale can be substantial. Whether the law is proportionate is debated; that it works is not.

Milan, Italy: You Must Smile

An old municipal ordinance in Milan reportedly requires citizens to smile at all times in public — with exceptions for hospitals and funerals. The law is rarely if ever enforced, but it survives in the city's legal code as a curious relic, perhaps reflecting an era when civic cheerfulness was considered a matter of public order. Milan's fashion-forward, fast-moving residents have largely declined to notice.

Denmark: Your Horse Must Not Be Left Untied

Danish law still includes provisions requiring horses to be properly secured when left in public places. In an era of cars and bicycles, this is not exactly a pressing concern, but the law persists — a holdover from a time when loose horses were a genuine public safety hazard in city streets. The Danish legal system, like most, retains many such anachronisms simply because updating every obsolete statute is an enormous undertaking.

Switzerland: No Flushing After 10pm

In some Swiss apartment buildings, local noise ordinances are interpreted to prohibit flushing toilets after 10pm, as the noise is considered a disturbance to neighbours. Switzerland's famous commitment to orderliness and consideration for others is admirable, but critics have noted that this particular application of the principle creates its own rather obvious problems.

The United Kingdom: A Collection of Curiosities

Britain's centuries-deep legal tradition has left behind a remarkable collection of oddities:

  • It was historically illegal to die in the Houses of Parliament — though enforcement was, practically speaking, challenging
  • A law once existed requiring taxi drivers to carry a bale of hay (a holdover from horse-drawn cab regulations)
  • In York, it is technically legal to shoot a Scotsman with a crossbow within the city walls — after midnight and with a bow and arrow. This is, of course, entirely unenforceable and no one should attempt it
  • Placing a postage stamp bearing the monarch's image upside down on an envelope is technically an act of treason under some readings of obsolete law

Most of these British curiosities were never formally repealed — they simply became dead letters as society and enforcement priorities moved on.

Why Strange Laws Survive

The persistence of odd laws tells us something important about how legal systems work. Legislatures spend their time on current priorities; repealing old, harmless laws rarely rises to the top of the agenda. The effort of identifying, cataloguing, and formally abolishing every outdated statute is immense. Unless a law causes active harm, it tends to stay on the books indefinitely.

Occasionally, however, an ancient law resurfaces in unexpected ways. Legal historians and curious lawyers sometimes discover that old statutes provide unexpected precedents or complicate modern cases. The law, it turns out, has a long memory — even when the problem it was designed to solve has been forgotten entirely.

The Takeaway

Strange laws are not just curiosities. They are fossils — preserved impressions of the concerns, values, and everyday problems of past societies. Reading them with curiosity rather than condescension reveals a great deal about how communities have tried, throughout history, to manage the messy, unpredictable business of living together.
