Generally, citation rules are all a bit weird since the aim is to represent a resource in as small a space as possible. Hopefully, we are communicating with others who speak our "citation language." The Bluebook is not comprehensive for citing laws everywhere. For the most part, when one begins to cite uncommon resources or laws that are far afield of the usual statutes, cases, and regulations in the United States, the rules aren't specific as to how to do it properly. You must then make some analogies from your resource to a known resource to create a viable citation. Sometimes you may need to consult with a law librarian or others who are knowledgeable about your resource because sometimes "it takes a village" to come up with a viable citation.
Citations are to the 20th edition of The Bluebook, A Uniform System of Citation.
NEVER use the two character postal abbreviations for states. Look up the abbreviation for the state in Table 10.1, Geographical Terms, U.S. states, cities, and territories. They use the old style state abbreviations up to four characters in length.
NEVER use "at" before a section (§) or paragraph (¶) symbol. Weird Rule #3 stems from pinciting in Short Form Citations (B4, R4). The word "at" precedes the pincite page number, but Rule 3.3 advises you to never use "at" before a section or paragraph symbol.
