All of the following are forms of legislative law EXCEPT

• A. The federal Constitution.
• B. Administrative decisions.
• C. Statutes.
• D. Treaties.

Answer: (B)

The key idea is distinguishing sources of law that come from the legislature from those that come from agencies. Legislative law is created through formal acts by the legislative branch and includes foundational rules like the Constitution, statutes enacted by lawmakers, and treaties that have been ratified and given domestic effect. Administrative decisions, by contrast, come from government agencies acting under delegated authority; they interpret and implement statutes and create regulations, but they are not themselves acts of the legislature. They are part of administrative law, not legislative law, even though they bind people and can have the force of law. So administrative decisions are not forms of legislative law, making them the correct choice.
