A related law is the title of the edict or legal text which establishes or regulates an object. This can be used to refer to national laws, local regulations, administrative decisions, international treaties, and similar government documents.
The value is free-form text in the local language. One may additionally use related_law:url=* to link to a URL where one can read the legal document, if it is published online by the government.
This tag was originally introduced for boundary=* (especially boundary=protected_area), when the boundary is either defined or regulated by law, but the tag may also be useful for other sorts of OSM objects.
