Sooner or later somebody has to put a rule in writing - an organiser setting conditions of entry, a coach answering a parent, a competitor making a complaint. Quoting it properly saves a great deal of argument later.

Quote the number, not your memory of it

Write the rule number and the words, rather than your own summary of what it means. "Rule 41.5 permits a designer label where it has been approved and recorded in the Sponsor Tag Register" settles a question. "I'm fairly sure maker's labels are allowed" starts one.

Link to the exact clause

The rules are published as a wiki, and every clause has its own web address. Open the clause and copy the address from your browser. It looks like this:

https://dancesport.org.au/dswiki/doku.php?id=rules:competitors#r35_4

The part after the # is what matters. Without it the reader lands at the top of a long page and has to hunt; with it they land on the clause itself. Whenever you search on the Rules page, the links beside each result already carry it - so the simplest method is to search, then copy the link.

If you are writing conditions of entry

Organisers should cite the rule number in the conditions rather than repeating the rule in their own words. Rewording a rule creates a second version of it, and if the two ever differ it is the organiser who has to explain why.

Rule numbers change

Rules are occasionally renumbered when a rulebook is revised - the words stay the same but the number moves. If you are quoting from an older document, check the number still points where you think it does before you send it. The search will tell you in seconds.
