There is often an appetite for more detailed instructions. Organisations and societies generate guidelines, standards, instructions, laws etc. No matter how detailed they are, it seems that more detail is needed to handle exceptions or resolve ambiguities.
It has been noted that the 10 Commandments (Exodus Chapter 20), which provide a legal and moral code for pretty much every aspect of a society (in English translation, New International Version) comprises about 287 words.
The American Declaration of Independence is some 1320 words[1] (more if you include title, signatories etc).
It has also been often reported that the EU Regulation on the export of duck eggs amounted to 46,000 words. Alas, this is widely recognised as a myth. But just because there are some popular myths out there does not weaken the overall case that there is a proliferation of words in the pursuit of precise regulations. And this pursuit can never reach its goal.
For EU regulations, I have not found a site that lists them in order of size but just picking a few it is easy to find some quite substantial ones. For example “REGULATION (EU) No 1151/2012 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 21 November 2012 on quality schemes for agricultural products and foodstuffs “ comes in at over 17,000 words.
A report that regulations about cabbages came to 26,000 words is also reported to be a myth but I have a copy of the document (Not EU Regulation but a Red Tractor publication).
