Court opinions and articles don’t change. An article or court opinion will never be updated. Court opinions can be effected by later decisions, their authoritative value can be reduced or eliminated but the text of the original opinion will remain the same. So we can take that opinion stick it in a book and just leave it there. But that’s not true for statutes and regulations. Every time a legislature meets some statute is going to change and when statutes change then the regulations change. And because of that dynamic character we don’t just stick statutes and regulations in books and leave them there. So to cite to statutes and regulations we’ve developed differing numbering systems.

36 C.F.R. §800.4 (2011)
Administrative agencies are part of the executive branch. Congress delegates the power to issue regulations, known as promulgation, and to adjudicate disputes. Congress delegates this power with the expectation that the regulations will carry out intent of legislature. If the regulations, also called rules, are properly promulgated and fulfill the intent of the statute they have the same legal effect as statutes.The regulation above is for the identification of historic properties under the §106 process.
