What term refers to a collection of rules enacted by law in a particular jurisdiction?

The term that refers to a collection of rules enacted by law in a particular jurisdiction is known as a "Code." Codes are comprehensive sets of laws that are organized by subject matter, providing a systematic framework for governance in various areas, including criminal law, civil law, and commercial law, among others.

For instance, in fire safety and prevention contexts, a fire code would include regulations and requirements necessary to ensure safety against fire hazards. This body of rules is officially adopted and enforced by governmental bodies and is designed to be easily referenced.

While regulations and statutes also represent rules, they do not encompass the same structured, comprehensive nature as a code. Regulations typically pertain to specific rule-making by government agencies to enforce statutes, while statutes are individual laws enacted by a legislature. Guidelines, meanwhile, generally refer to recommended practices that may not have the force of law. Thus, a code stands out as the most appropriate term for a systematic body of rules within a jurisdiction.
