What types of legal sources can applicable law include?

Applicable law can encompass a wide array of legal sources, which is why the correct answer covers all of the provided options.

Constitutional provisions establish the foundational legal principles of a jurisdiction. They provide the highest authority within the legal framework and guide the interpretation and application of other laws.

Case law doctrines are derived from judicial decisions and serve as precedents that courts must follow when similar issues arise. This body of law evolves with each court ruling, reflecting the common law tradition.

Secondary authorities, such as legal commentaries and analyses, help interpret and clarify the law but do not themselves create binding legal standards.

Ordinances refer to laws enacted by local governmental bodies, while regulations are detailed directives issued by government agencies to enforce statutes. These provide the necessary detail and structure to implement and enforce laws effectively.

Statutes are formal written laws, essential components of the legal system which dictate specific legal requirements and standards.

Principles can encompass general legal doctrines or maxims that guide legal reasoning and decision-making.

Guides may include resources such as legal textbooks, treatises
