Unfortunately, most of these (in the modern day) really are about local governance structures (eccentric or otherwise; Darazik’s kenothronism, and indeed those of Glennén and Syndal; Eävalle’s auction; et. al.).
Historians argue about how much this qualifies as a “just as planned”, or not, but it can’t be denied that in the years after the Great Convention (devised 502-526, constituting a universal legal code) was promulgated - the Universal Commerce Code having arrived on the scene a couple of centuries earlier - the vast bulk of both criminal and commercial law were harmonized.
It also didn’t help much that a lot of what we might consider local laws and ordinances were conveniently kicked over into the realm of property rights and contracts. (If a citysteader has a particular vision for Ameri, or Chanayíma, or Chresytíäné, or Máhadenel, it’s easy enough to phrase that as a specialized property right in aesthetics.)
Some of them are effectively permissible carve-outs from more general laws. While anharmonic indecency is the general legal means of telling people to put on a damn shirt, etc., when wandering through public volumes¹, the Cyrsan islands - and other regions of Makaé-lin culture, such as Clajdíä (Thirteen Colonies) - revise this such that it can only be used to tell people to put on some damn pants. On similar cultural grounds, Paltraeth and its daughter worlds make it clear that the traditional kaeth body-check-as-greeting, etal., isn’t legal battery even if it feels like it.
That said, there are others. That also said, I don’t have a definitive list handy, alas, But one that did come to mind is this:
A large chunk of the nation of Palar lives in floating sky cities, so they have local laws concerning shoving, overcrowding, and suchlike that are much more toothsome than standard Imperial laws, because people might fall a long damn way. (Such were later cross-ported to the cloud coral islands of Torachal and the floatstone skymotes of Calríäkay.)
As I think of more, I shall try and remember to post them.
Incidentally, while JHPrime is correct here:
And conlegiality isn’t an example of this, the authors of the conlegius statutes were inspired by the same fundamental principle.
- Not all public volumes: not, for an example neither complete nor conclusive, bath-houses, hot springs, bathing beaches, or palaestrae.
